5 Changes between 0.9.5a and 0.9.6 [xx XXX 2000]
7 *) Add a few more EBCDIC conditionals that make `req' and `x509'
8 work better on such systems.
9 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
11 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
12 Update PKCS12_parse() so it copies the friendlyName and the
13 keyid to the certificates aux info.
16 *) Fix bug in PKCS7_verify() which caused an infinite loop
17 if there was more than one signature.
18 [Sven Uszpelkat <su@celocom.de>]
20 *) Major change in util/mkdef.pl to include extra information
21 about each symbol, as well as presentig variables as well
22 as functions. This change means that there's n more need
23 to rebuild the .num files when some algorithms are excluded.
26 *) Allow the verify time to be set by an application,
27 rather than always using the current time.
30 *) Phase 2 verify code reorganisation. The certificate
31 verify code now looks up an issuer certificate by a
32 number of criteria: subject name, authority key id
33 and key usage. It also verifies self signed certificates
34 by the same criteria. The main comparison function is
35 X509_check_issued() which performs these checks.
37 Lot of changes were necessary in order to support this
38 without completely rewriting the lookup code.
40 Authority and subject key identifier are now cached.
42 The LHASH 'certs' is X509_STORE has now been replaced
43 by a STACK_OF(X509_OBJECT). This is mainly because an
44 LHASH can't store or retrieve multiple objects with
47 As a result various functions (which were all internal
48 use only) have changed to handle the new X509_STORE
49 structure. This will break anything that messed round
50 with X509_STORE internally.
52 The functions X509_STORE_add_cert() now checks for an
53 exact match, rather than just subject name.
55 The X509_STORE API doesn't directly support the retrieval
56 of multiple certificates matching a given criteria, however
57 this can be worked round by performing a lookup first
58 (which will fill the cache with candidate certificates)
59 and then examining the cache for matches. This is probably
60 the best we can do without throwing out X509_LOOKUP
61 entirely (maybe later...).
63 The X509_VERIFY_CTX structure has been enhanced considerably.
65 All certificate lookup operations now go via a get_issuer()
66 callback. Although this currently uses an X509_STORE it
67 can be replaced by custom lookups. This is a simple way
68 to bypass the X509_STORE hackery necessary to make this
69 work and makes it possible to use more efficient techniques
70 in future. A very simple version which uses a simple
71 STACK for its trusted certificate store is also provided
72 using X509_STORE_CTX_trusted_stack().
74 The verify_cb() and verify() callbacks now have equivalents
75 in the X509_STORE_CTX structure.
77 X509_STORE_CTX also has a 'flags' field which can be used
78 to customise the verify behaviour.
81 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
82 excludes S/MIME capabilities.
85 *) When a certificate request is read in keep a copy of the
86 original encoding of the signed data and use it when outputing
87 again. Signatures then use the original encoding rather than
88 a decoded, encoded version which may cause problems if the
89 request is improperly encoded.
92 *) For consistency with other BIO_puts implementations, call
93 buffer_write(b, ...) directly in buffer_puts instead of calling
96 In BIO_puts, increment b->num_write as in BIO_write.
97 [Peter.Sylvester@EdelWeb.fr]
99 *) Fix BN_mul_word for the case where the word is 0. (We have to use
100 BN_zero, we may not return a BIGNUM with an array consisting of
104 *) Avoid calling abort() from within the library when problems are
105 detected, except if preprocessor symbols have been defined
106 (such as REF_CHECK, BN_DEBUG etc.).
109 *) New openssl application 'rsautl'. This utility can be
110 used for low level RSA operations. DER public key
111 BIO/fp routines also added.
114 *) New Configure entry and patches for compiling on QNX 4.
115 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
117 *) A demo state-machine implementation was sponsored by
118 Nuron (http://www.nuron.com/) and is now available in
122 *) New options added to the 'dgst' utility for signature
123 generation and verification.
126 *) Unrecognized PKCS#7 content types are now handled via a
127 catch all ASN1_TYPE structure. This allows unsupported
128 types to be stored as a "blob" and an application can
129 encode and decode it manually.
132 *) Fix various signed/unsigned issues to make a_strex.c
134 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
136 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
137 length if passed a buffer. ASN1_INTEGER_to_BN failed
138 if passed a NULL BN and its argument was negative.
139 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
141 *) Modification to PKCS#7 encoding routines to output definite
142 length encoding. Since currently the whole structures are in
143 memory there's not real point in using indefinite length
144 constructed encoding. However if OpenSSL is compiled with
145 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
148 *) Added BIO_vprintf() and BIO_vsnprintf().
151 *) Added more prefixes to parse for in the the strings written
152 through a logging bio, to cover all the levels that are available
153 through syslog. The prefixes are now:
155 PANIC, EMERG, EMR => LOG_EMERG
156 ALERT, ALR => LOG_ALERT
157 CRIT, CRI => LOG_CRIT
158 ERROR, ERR => LOG_ERR
159 WARNING, WARN, WAR => LOG_WARNING
160 NOTICE, NOTE, NOT => LOG_NOTICE
161 INFO, INF => LOG_INFO
162 DEBUG, DBG => LOG_DEBUG
164 and as before, if none of those prefixes are present at the
165 beginning of the string, LOG_ERR is chosen.
167 On Win32, the LOG_* levels are mapped according to this:
169 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
170 LOG_WARNING => EVENTLOG_WARNING_TYPE
171 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
175 *) Made it possible to reconfigure with just the configuration
176 argument "reconf" or "reconfigure". The command line arguments
177 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
178 and are retrieved from there when reconfiguring.
182 [Assar Westerlund <assar@sics.se>, Richard Levitte]
184 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
187 *) The obj_dat.pl script was messing up the sorting of object
188 names. The reason was that it compared the quoted version
189 of strings as a result "OCSP" > "OCSP Signing" because
190 " > SPACE. Changed script to store unquoted versions of
191 names and add quotes on output. It was also omitting some
192 names from the lookup table if they were given a default
193 value (that is if SN is missing it is given the same
194 value as LN and vice versa), these are now added on the
195 grounds that if an object has a name we should be able to
196 look it up. Finally added warning output when duplicate
197 short or long names are found.
200 *) Changes needed for Tandem NSK.
201 [Scott Uroff scott@xypro.com]
203 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
204 RSA_padding_check_SSLv23(), special padding was never detected
205 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
206 version rollback attacks was not effective.
208 In s23_clnt.c, don't use special rollback-attack detection padding
209 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
210 client; similarly, in s23_srvr.c, don't do the rollback check if
211 SSL 2.0 is the only protocol enabled in the server.
214 *) Make it possible to get hexdumps of unprintable data with 'openssl
215 asn1parse'. By implication, the functions ASN1_parse_dump() and
216 BIO_dump_indent() are added.
219 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
220 these print out strings and name structures based on various
221 flags including RFC2253 support and proper handling of
222 multibyte characters. Added options to the 'x509' utility
223 to allow the various flags to be set.
226 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
227 Also change the functions X509_cmp_current_time() and
228 X509_gmtime_adj() work with an ASN1_TIME structure,
229 this will enable certificates using GeneralizedTime in validity
233 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
234 negative public key encodings) on by default,
235 NO_NEG_PUBKEY_BUG can be set to disable it.
238 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
239 content octets. An i2c_ASN1_OBJECT is unnecessary because
240 the encoding can be trivially obtained from the structure.
243 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
244 not read locks (CRYPTO_r_[un]lock).
247 *) A first attempt at creating official support for shared
248 libraries through configuration. I've kept it so the
249 default is static libraries only, and the OpenSSL programs
250 are always statically linked for now, but there are
251 preparations for dynamic linking in place.
252 This has been tested on Linux and True64.
255 *) Randomness polling function for Win9x, as described in:
256 Peter Gutmann, Software Generation of Practically Strong
260 *) Fix so PRNG is seeded in req if using an already existing
264 *) New options to smime application. -inform and -outform
265 allow alternative formats for the S/MIME message including
266 PEM and DER. The -content option allows the content to be
267 specified separately. This should allow things like Netscape
268 form signing output easier to verify.
271 *) Fix the ASN1 encoding of tags using the 'long form'.
274 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
275 STRING types. These convert content octets to and from the
276 underlying type. The actual tag and length octets are
277 already assumed to have been read in and checked. These
278 are needed because all other string types have virtually
279 identical handling apart from the tag. By having versions
280 of the ASN1 functions that just operate on content octets
281 IMPLICIT tagging can be handled properly. It also allows
282 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
283 and ASN1_INTEGER are identical apart from the tag.
286 *) Change the handling of OID objects as follows:
288 - New object identifiers are inserted in objects.txt, following
289 the syntax given in objects.README.
290 - objects.pl is used to process obj_mac.num and create a new
292 - obj_dat.pl is used to create a new obj_dat.h, using the data in
295 This is currently kind of a hack, and the perl code in objects.pl
296 isn't very elegant, but it works as I intended. The simplest way
297 to check that it worked correctly is to look in obj_dat.h and
298 check the array nid_objs and make sure the objects haven't moved
299 around (this is important!). Additions are OK, as well as
300 consistent name changes.
303 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
306 *) Addition of the command line parameter '-rand file' to 'openssl req'.
307 The given file adds to whatever has already been seeded into the
308 random pool through the RANDFILE configuration file option or
309 environment variable, or the default random state file.
312 *) mkstack.pl now sorts each macro group into lexical order.
313 Previously the output order depended on the order the files
314 appeared in the directory, resulting in needless rewriting
318 *) Patches to make OpenSSL compile under Win32 again. Mostly
319 work arounds for the VC++ problem that it treats func() as
320 func(void). Also stripped out the parts of mkdef.pl that
321 added extra typesafe functions: these no longer exist.
324 *) Reorganisation of the stack code. The macros are now all
325 collected in safestack.h . Each macro is defined in terms of
326 a "stack macro" of the form SKM_<name>(type, a, b). The
327 DEBUG_SAFESTACK is now handled in terms of function casts,
328 this has the advantage of retaining type safety without the
329 use of additional functions. If DEBUG_SAFESTACK is not defined
330 then the non typesafe macros are used instead. Also modified the
331 mkstack.pl script to handle the new form. Needs testing to see
332 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
333 the default if no major problems. Similar behaviour for ASN1_SET_OF
337 *) When some versions of IIS use the 'NET' form of private key the
338 key derivation algorithm is different. Normally MD5(password) is
339 used as a 128 bit RC4 key. In the modified case
340 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
341 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
342 as the old Netscape_RSA functions except they have an additional
343 'sgckey' parameter which uses the modified algorithm. Also added
344 an -sgckey command line option to the rsa utility. Thanks to
345 Adrian Peck <bertie@ncipher.com> for posting details of the modified
346 algorithm to openssl-dev.
349 *) The evp_local.h macros were using 'c.##kname' which resulted in
350 invalid expansion on some systems (SCO 5.0.5 for example).
351 Corrected to 'c.kname'.
352 [Phillip Porch <root@theporch.com>]
354 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
355 a STACK of email addresses from a certificate or request, these look
356 in the subject name and the subject alternative name extensions and
357 omit any duplicate addresses.
360 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
361 This makes DSA verification about 2 % faster.
364 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
365 (meaning that now 2^5 values will be precomputed, which is only 4 KB
366 plus overhead for 1024 bit moduli).
367 This makes exponentiations about 0.5 % faster for 1024 bit
368 exponents (as measured by "openssl speed rsa2048").
371 *) Rename memory handling macros to avoid conflicts with other
373 Malloc => OPENSSL_malloc
374 Malloc_locked => OPENSSL_malloc_locked
375 Realloc => OPENSSL_realloc
379 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
380 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
384 [John Jarvie <jjarvie@newsguy.com>]
386 *) The type-safe stack code has been rejigged. It is now only compiled
387 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
388 by default all type-specific stack functions are "#define"d back to
389 standard stack functions. This results in more streamlined output
390 but retains the type-safety checking possibilities of the original
394 *) The STACK code has been cleaned up, and certain type declarations
395 that didn't make a lot of sense have been brought in line. This has
396 also involved a cleanup of sorts in safestack.h to more correctly
397 map type-safe stack functions onto their plain stack counterparts.
398 This work has also resulted in a variety of "const"ifications of
399 lots of the code, especially "_cmp" operations which should normally
400 be prototyped with "const" parameters anyway.
403 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
404 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
405 (The PRNG state consists of two parts, the large pool 'state' and 'md',
406 where all of 'md' is used each time the PRNG is used, but 'state'
407 is used only indexed by a cyclic counter. As entropy may not be
408 well distributed from the beginning, 'md' is important as a
409 chaining variable. However, the output function chains only half
410 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
411 all of 'md', and seeding with STATE_SIZE dummy bytes will result
412 in all of 'state' being rewritten, with the new values depending
413 on virtually all of 'md'. This overcomes the 80 bit limitation.)
416 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
417 the handshake is continued after ssl_verify_cert_chain();
418 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
419 can lead to 'unexplainable' connection aborts later.
420 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
422 *) Major EVP API cipher revision.
423 Add hooks for extra EVP features. This allows various cipher
424 parameters to be set in the EVP interface. Support added for variable
425 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
426 setting of RC2 and RC5 parameters.
428 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
431 Remove lots of duplicated code from the EVP library. For example *every*
432 cipher init() function handles the 'iv' in the same way according to the
433 cipher mode. They also all do nothing if the 'key' parameter is NULL and
434 for CFB and OFB modes they zero ctx->num.
436 New functionality allows removal of S/MIME code RC2 hack.
438 Most of the routines have the same form and so can be declared in terms
441 By shifting this to the top level EVP_CipherInit() it can be removed from
442 all individual ciphers. If the cipher wants to handle IVs or keys
443 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
446 Change lots of functions like EVP_EncryptUpdate() to now return a
447 value: although software versions of the algorithms cannot fail
448 any installed hardware versions can.
451 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
452 this option is set, tolerate broken clients that send the negotiated
453 protocol version number instead of the requested protocol version
457 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
458 i.e. non-zero for export ciphersuites, zero otherwise.
459 Previous versions had this flag inverted, inconsistent with
460 rsa_tmp_cb (..._TMP_RSA_CB).
461 [Bodo Moeller; problem reported by Amit Chopra]
463 *) Add missing DSA library text string. Work around for some IIS
464 key files with invalid SEQUENCE encoding.
467 *) Add a document (doc/standards.txt) that list all kinds of standards
468 and so on that are implemented in OpenSSL.
471 *) Enhance c_rehash script. Old version would mishandle certificates
472 with the same subject name hash and wouldn't handle CRLs at all.
473 Added -fingerprint option to crl utility, to support new c_rehash
477 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
480 *) Fix for SSL server purpose checking. Server checking was
481 rejecting certificates which had extended key usage present
482 but no ssl client purpose.
483 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
485 *) Make PKCS#12 code work with no password. The PKCS#12 spec
486 is a little unclear about how a blank password is handled.
487 Since the password in encoded as a BMPString with terminating
488 double NULL a zero length password would end up as just the
489 double NULL. However no password at all is different and is
490 handled differently in the PKCS#12 key generation code. NS
491 treats a blank password as zero length. MSIE treats it as no
492 password on export: but it will try both on import. We now do
493 the same: PKCS12_parse() tries zero length and no password if
494 the password is set to "" or NULL (NULL is now a valid password:
495 it wasn't before) as does the pkcs12 application.
498 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
499 perror when PEM_read_bio_X509_REQ fails, the error message must
500 be obtained from the error queue.
503 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
504 it in ERR_remove_state if appropriate, and change ERR_get_state
505 accordingly to avoid race conditions (this is necessary because
506 thread_hash is no longer constant once set).
509 *) Bugfix for linux-elf makefile.one.
512 *) RSA_get_default_method() will now cause a default
513 RSA_METHOD to be chosen if one doesn't exist already.
514 Previously this was only set during a call to RSA_new()
515 or RSA_new_method(NULL) meaning it was possible for
516 RSA_get_default_method() to return NULL.
519 *) Added native name translation to the existing DSO code
520 that will convert (if the flag to do so is set) filenames
521 that are sufficiently small and have no path information
522 into a canonical native form. Eg. "blah" converted to
523 "libblah.so" or "blah.dll" etc.
526 *) New function ERR_error_string_n(e, buf, len) which is like
527 ERR_error_string(e, buf), but writes at most 'len' bytes
528 including the 0 terminator. For ERR_error_string_n, 'buf'
530 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
532 *) CONF library reworked to become more general. A new CONF
533 configuration file reader "class" is implemented as well as a
534 new functions (NCONF_*, for "New CONF") to handle it. The now
535 old CONF_* functions are still there, but are reimplemented to
536 work in terms of the new functions. Also, a set of functions
537 to handle the internal storage of the configuration data is
538 provided to make it easier to write new configuration file
539 reader "classes" (I can definitely see something reading a
540 configuration file in XML format, for example), called _CONF_*,
541 or "the configuration storage API"...
543 The new configuration file reading functions are:
545 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
546 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
548 NCONF_default, NCONF_WIN32
550 NCONF_dump_fp, NCONF_dump_bio
552 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
553 NCONF_new creates a new CONF object. This works in the same way
554 as other interfaces in OpenSSL, like the BIO interface.
555 NCONF_dump_* dump the internal storage of the configuration file,
556 which is useful for debugging. All other functions take the same
557 arguments as the old CONF_* functions wth the exception of the
558 first that must be a `CONF *' instead of a `LHASH *'.
560 To make it easer to use the new classes with the old CONF_* functions,
561 the function CONF_set_default_method is provided.
564 *) Add '-tls1' option to 'openssl ciphers', which was already
565 mentioned in the documentation but had not been implemented.
566 (This option is not yet really useful because even the additional
567 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
570 *) Initial DSO code added into libcrypto for letting OpenSSL (and
571 OpenSSL-based applications) load shared libraries and bind to
572 them in a portable way.
573 [Geoff Thorpe, with contributions from Richard Levitte]
575 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
577 *) Make sure _lrotl and _lrotr are only used with MSVC.
579 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
580 (the default implementation of RAND_status).
582 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
583 to '-clrext' (= clear extensions), as intended and documented.
584 [Bodo Moeller; inconsistency pointed out by Michael Attili
587 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
588 was larger than the MD block size.
589 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
591 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
592 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
593 using the passed key: if the passed key was a private key the result
594 of X509_print(), for example, would be to print out all the private key
598 *) des_quad_cksum() byte order bug fix.
599 [Ulf Möller, using the problem description in krb4-0.9.7, where
600 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
602 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
604 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
606 *) For easily testing in shell scripts whether some command
607 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
608 returns with exit code 0 iff no command of the given name is available.
609 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
610 the output goes to stdout and nothing is printed to stderr.
611 Additional arguments are always ignored.
613 Since for each cipher there is a command of the same name,
614 the 'no-cipher' compilation switches can be tested this way.
616 ('openssl no-XXX' is not able to detect pseudo-commands such
617 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
620 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
623 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
624 is set; it will be thrown away anyway because each handshake creates
626 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
627 to parameters -- in previous versions (since OpenSSL 0.9.3) the
628 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
629 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
632 *) New s_client option -ign_eof: EOF at stdin is ignored, and
633 'Q' and 'R' lose their special meanings (quit/renegotiate).
634 This is part of what -quiet does; unlike -quiet, -ign_eof
635 does not suppress any output.
638 *) Add compatibility options to the purpose and trust code. The
639 purpose X509_PURPOSE_ANY is "any purpose" which automatically
640 accepts a certificate or CA, this was the previous behaviour,
641 with all the associated security issues.
643 X509_TRUST_COMPAT is the old trust behaviour: only and
644 automatically trust self signed roots in certificate store. A
645 new trust setting X509_TRUST_DEFAULT is used to specify that
646 a purpose has no associated trust setting and it should instead
647 use the value in the default purpose.
650 *) Fix the PKCS#8 DSA private key code so it decodes keys again
651 and fix a memory leak.
654 *) In util/mkerr.pl (which implements 'make errors'), preserve
655 reason strings from the previous version of the .c file, as
656 the default to have only downcase letters (and digits) in
657 automatically generated reasons codes is not always appropriate.
660 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
661 using strerror. Previously, ERR_reason_error_string() returned
662 library names as reason strings for SYSerr; but SYSerr is a special
663 case where small numbers are errno values, not library numbers.
666 *) Add '-dsaparam' option to 'openssl dhparam' application. This
667 converts DSA parameters into DH parameters. (When creating parameters,
668 DSA_generate_parameters is used.)
671 *) Include 'length' (recommended exponent length) in C code generated
672 by 'openssl dhparam -C'.
675 *) The second argument to set_label in perlasm was already being used
676 so couldn't be used as a "file scope" flag. Moved to third argument
680 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
681 instead of RAND_bytes for encryption IVs and salts.
684 *) Include RAND_status() into RAND_METHOD instead of implementing
685 it only for md_rand.c Otherwise replacing the PRNG by calling
686 RAND_set_rand_method would be impossible.
689 *) Don't let DSA_generate_key() enter an infinite loop if the random
690 number generation fails.
693 *) New 'rand' application for creating pseudo-random output.
696 *) Added configuration support for Linux/IA64
697 [Rolf Haberrecker <rolf@suse.de>]
699 *) Assembler module support for Mingw32.
702 *) Shared library support for HPUX (in shlib/).
703 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
705 *) Shared library support for Solaris gcc.
706 [Lutz Behnke <behnke@trustcenter.de>]
708 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
710 *) PKCS7_encrypt() was adding text MIME headers twice because they
711 were added manually and by SMIME_crlf_copy().
714 *) In bntest.c don't call BN_rand with zero bits argument.
715 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
717 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
718 case was implemented. This caused BN_div_recp() to fail occasionally.
721 *) Add an optional second argument to the set_label() in the perl
722 assembly language builder. If this argument exists and is set
723 to 1 it signals that the assembler should use a symbol whose
724 scope is the entire file, not just the current function. This
725 is needed with MASM which uses the format label:: for this scope.
726 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
728 *) Change the ASN1 types so they are typedefs by default. Before
729 almost all types were #define'd to ASN1_STRING which was causing
730 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
734 *) Change names of new functions to the new get1/get0 naming
735 convention: After 'get1', the caller owns a reference count
736 and has to call ..._free; 'get0' returns a pointer to some
737 data structure without incrementing reference counters.
738 (Some of the existing 'get' functions increment a reference
739 counter, some don't.)
740 Similarly, 'set1' and 'add1' functions increase reference
741 counters or duplicate objects.
744 *) Allow for the possibility of temp RSA key generation failure:
745 the code used to assume it always worked and crashed on failure.
748 *) Fix potential buffer overrun problem in BIO_printf().
749 [Ulf Möller, using public domain code by Patrick Powell; problem
750 pointed out by David Sacerdote <das33@cornell.edu>]
752 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
753 RAND_egd() and RAND_status(). In the command line application,
754 the EGD socket can be specified like a seed file using RANDFILE
758 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
759 Some CAs (e.g. Verisign) distribute certificates in this form.
762 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
763 list to exclude them. This means that no special compilation option
764 is needed to use anonymous DH: it just needs to be included in the
768 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
769 EVP_MD_type. The old functionality is available in a new macro called
770 EVP_MD_md(). Change code that uses it and update docs.
773 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
774 where the 'void *' argument is replaced by a function pointer argument.
775 Previously 'void *' was abused to point to functions, which works on
776 many platforms, but is not correct. As these functions are usually
777 called by macros defined in OpenSSL header files, most source code
778 should work without changes.
781 *) <openssl/opensslconf.h> (which is created by Configure) now contains
782 sections with information on -D... compiler switches used for
783 compiling the library so that applications can see them. To enable
784 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
785 must be defined. E.g.,
786 #define OPENSSL_ALGORITHM_DEFINES
787 #include <openssl/opensslconf.h>
788 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
789 [Richard Levitte, Ulf and Bodo Möller]
791 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
795 *) Change the 'other' type in certificate aux info to a STACK_OF
796 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
797 the required ASN1 format: arbitrary types determined by an OID.
800 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
801 argument to 'req'. This is not because the function is newer or
802 better than others it just uses the work 'NEW' in the certificate
803 request header lines. Some software needs this.
806 *) Reorganise password command line arguments: now passwords can be
807 obtained from various sources. Delete the PEM_cb function and make
808 it the default behaviour: i.e. if the callback is NULL and the
809 usrdata argument is not NULL interpret it as a null terminated pass
810 phrase. If usrdata and the callback are NULL then the pass phrase
811 is prompted for as usual.
814 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
815 the support is automatically enabled. The resulting binaries will
816 autodetect the card and use it if present.
817 [Ben Laurie and Compaq Inc.]
819 *) Work around for Netscape hang bug. This sends certificate request
820 and server done in one record. Since this is perfectly legal in the
821 SSL/TLS protocol it isn't a "bug" option and is on by default. See
822 the bugs/SSLv3 entry for more info.
825 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
828 *) Add -rand argument to smime and pkcs12 applications and read/write
832 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
835 *) Add command line password options to the remaining applications.
838 *) Bug fix for BN_div_recp() for numerators with an even number of
842 *) More tests in bntest.c, and changed test_bn output.
845 *) ./config recognizes MacOS X now.
848 *) Bug fix for BN_div() when the first words of num and divsor are
849 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
852 *) Add support for various broken PKCS#8 formats, and command line
853 options to produce them.
856 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
857 get temporary BIGNUMs from a BN_CTX.
860 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
864 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
865 include a #define from the old name to the new. The original intent
866 was that statically linked binaries could for example just call
867 SSLeay_add_all_ciphers() to just add ciphers to the table and not
868 link with digests. This never worked becayse SSLeay_add_all_digests()
869 and SSLeay_add_all_ciphers() were in the same source file so calling
870 one would link with the other. They are now in separate source files.
873 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
876 *) Use a less unusual form of the Miller-Rabin primality test (it used
877 a binary algorithm for exponentiation integrated into the Miller-Rabin
878 loop, our standard modexp algorithms are faster).
881 *) Support for the EBCDIC character set completed.
882 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
884 *) Source code cleanups: use const where appropriate, eliminate casts,
885 use void * instead of char * in lhash.
888 *) Bugfix: ssl3_send_server_key_exchange was not restartable
889 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
890 this the server could overwrite ephemeral keys that the client
894 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
895 using 50 iterations of the Rabin-Miller test.
897 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
898 iterations of the Rabin-Miller test as required by the appendix
899 to FIPS PUB 186[-1]) instead of DSA_is_prime.
900 As BN_is_prime_fasttest includes trial division, DSA parameter
901 generation becomes much faster.
903 This implies a change for the callback functions in DSA_is_prime
904 and DSA_generate_parameters: The callback function is called once
905 for each positive witness in the Rabin-Miller test, not just
906 occasionally in the inner loop; and the parameters to the
907 callback function now provide an iteration count for the outer
908 loop rather than for the current invocation of the inner loop.
909 DSA_generate_parameters additionally can call the callback
910 function with an 'iteration count' of -1, meaning that a
911 candidate has passed the trial division test (when q is generated
912 from an application-provided seed, trial division is skipped).
915 *) New function BN_is_prime_fasttest that optionally does trial
916 division before starting the Rabin-Miller test and has
917 an additional BN_CTX * argument (whereas BN_is_prime always
918 has to allocate at least one BN_CTX).
919 'callback(1, -1, cb_arg)' is called when a number has passed the
920 trial division stage.
923 *) Fix for bug in CRL encoding. The validity dates weren't being handled
927 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
930 *) New function BN_pseudo_rand().
933 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
934 bignum version of BN_from_montgomery() with the working code from
935 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
939 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
940 made it impossible to use the same SSL_SESSION data structure in
941 SSL2 clients in multiple threads.
944 *) The return value of RAND_load_file() no longer counts bytes obtained
945 by stat(). RAND_load_file(..., -1) is new and uses the complete file
946 to seed the PRNG (previously an explicit byte count was required).
947 [Ulf Möller, Bodo Möller]
949 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
950 used (char *) instead of (void *) and had casts all over the place.
953 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
956 *) Retain source code compatibility for BN_prime_checks macro:
957 BN_is_prime(..., BN_prime_checks, ...) now uses
958 BN_prime_checks_for_size to determine the appropriate number of
959 Rabin-Miller iterations.
962 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
963 DH_CHECK_P_NOT_SAFE_PRIME.
964 (Check if this is true? OpenPGP calls them "strong".)
967 *) Merge the functionality of "dh" and "gendh" programs into a new program
968 "dhparam". The old programs are retained for now but will handle DH keys
969 (instead of parameters) in future.
972 *) Make the ciphers, s_server and s_client programs check the return values
973 when a new cipher list is set.
976 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
977 ciphers. Before when the 56bit ciphers were enabled the sorting was
980 The syntax for the cipher sorting has been extended to support sorting by
981 cipher-strength (using the strength_bits hard coded in the tables).
982 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
984 Fix a bug in the cipher-command parser: when supplying a cipher command
985 string with an "undefined" symbol (neither command nor alphanumeric
986 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
989 Due to the strength-sorting extension, the code of the
990 ssl_create_cipher_list() function was completely rearranged. I hope that
991 the readability was also increased :-)
992 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
994 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
995 for the first serial number and places 2 in the serial number file. This
996 avoids problems when the root CA is created with serial number zero and
997 the first user certificate has the same issuer name and serial number
1001 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
1002 the new code. Add documentation for this stuff.
1005 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
1006 X509_*() to X509at_*() on the grounds that they don't handle X509
1007 structures and behave in an analagous way to the X509v3 functions:
1008 they shouldn't be called directly but wrapper functions should be used
1011 So we also now have some wrapper functions that call the X509at functions
1012 when passed certificate requests. (TO DO: similar things can be done with
1013 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
1014 things. Some of these need some d2i or i2d and print functionality
1015 because they handle more complex structures.)
1018 *) Add missing #ifndefs that caused missing symbols when building libssl
1019 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
1020 NO_RSA in ssl/s2*.c.
1021 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
1023 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
1024 has a return value which indicates the quality of the random data
1025 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
1026 error queue. New function RAND_pseudo_bytes() generates output that is
1027 guaranteed to be unique but not unpredictable. RAND_add is like
1028 RAND_seed, but takes an extra argument for an entropy estimate
1029 (RAND_seed always assumes full entropy).
1032 *) Do more iterations of Rabin-Miller probable prime test (specifically,
1033 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
1034 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
1035 in crypto/bn/bn_prime.c for the complete table). This guarantees a
1036 false-positive rate of at most 2^-80 for random input.
1039 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
1042 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
1043 in the 0.9.5 release), this returns the chain
1044 from an X509_CTX structure with a dup of the stack and all
1045 the X509 reference counts upped: so the stack will exist
1046 after X509_CTX_cleanup() has been called. Modify pkcs12.c
1049 Also make SSL_SESSION_print() print out the verify return
1053 *) Add manpage for the pkcs12 command. Also change the default
1054 behaviour so MAC iteration counts are used unless the new
1055 -nomaciter option is used. This improves file security and
1056 only older versions of MSIE (4.0 for example) need it.
1059 *) Honor the no-xxx Configure options when creating .DEF files.
1062 *) Add PKCS#10 attributes to field table: challengePassword,
1063 unstructuredName and unstructuredAddress. These are taken from
1064 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
1065 international characters are used.
1067 More changes to X509_ATTRIBUTE code: allow the setting of types
1068 based on strings. Remove the 'loc' parameter when adding
1069 attributes because these will be a SET OF encoding which is sorted
1073 *) Initial changes to the 'req' utility to allow request generation
1074 automation. This will allow an application to just generate a template
1075 file containing all the field values and have req construct the
1078 Initial support for X509_ATTRIBUTE handling. Stacks of these are
1079 used all over the place including certificate requests and PKCS#7
1080 structures. They are currently handled manually where necessary with
1081 some primitive wrappers for PKCS#7. The new functions behave in a
1082 manner analogous to the X509 extension functions: they allow
1083 attributes to be looked up by NID and added.
1085 Later something similar to the X509V3 code would be desirable to
1086 automatically handle the encoding, decoding and printing of the
1087 more complex types. The string types like challengePassword can
1088 be handled by the string table functions.
1090 Also modified the multi byte string table handling. Now there is
1091 a 'global mask' which masks out certain types. The table itself
1092 can use the flag STABLE_NO_MASK to ignore the mask setting: this
1093 is useful when for example there is only one permissible type
1094 (as in countryName) and using the mask might result in no valid
1098 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
1099 SSL_get_peer_finished to allow applications to obtain the latest
1100 Finished messages sent to the peer or expected from the peer,
1101 respectively. (SSL_get_peer_finished is usually the Finished message
1102 actually received from the peer, otherwise the protocol will be aborted.)
1104 As the Finished message are message digests of the complete handshake
1105 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
1106 be used for external authentication procedures when the authentication
1107 provided by SSL/TLS is not desired or is not enough.
1110 *) Enhanced support for Alpha Linux is added. Now ./config checks if
1111 the host supports BWX extension and if Compaq C is present on the
1112 $PATH. Just exploiting of the BWX extension results in 20-30%
1113 performance kick for some algorithms, e.g. DES and RC4 to mention
1114 a couple. Compaq C in turn generates ~20% faster code for MD5 and
1118 *) Add support for MS "fast SGC". This is arguably a violation of the
1119 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
1120 weak crypto and after checking the certificate is SGC a second one
1121 with strong crypto. MS SGC stops the first handshake after receiving
1122 the server certificate message and sends a second client hello. Since
1123 a server will typically do all the time consuming operations before
1124 expecting any further messages from the client (server key exchange
1125 is the most expensive) there is little difference between the two.
1127 To get OpenSSL to support MS SGC we have to permit a second client
1128 hello message after we have sent server done. In addition we have to
1129 reset the MAC if we do get this second client hello.
1132 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
1133 if a DER encoded private key is RSA or DSA traditional format. Changed
1134 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
1135 format DER encoded private key. Newer code should use PKCS#8 format which
1136 has the key type encoded in the ASN1 structure. Added DER private key
1137 support to pkcs8 application.
1140 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
1141 ciphersuites has been selected (as required by the SSL 3/TLS 1
1142 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
1143 is set, we interpret this as a request to violate the specification
1144 (the worst that can happen is a handshake failure, and 'correct'
1145 behaviour would result in a handshake failure anyway).
1148 *) In SSL_CTX_add_session, take into account that there might be multiple
1149 SSL_SESSION structures with the same session ID (e.g. when two threads
1150 concurrently obtain them from an external cache).
1151 The internal cache can handle only one SSL_SESSION with a given ID,
1152 so if there's a conflict, we now throw out the old one to achieve
1156 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
1157 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
1158 some routines that use cipher OIDs: some ciphers do not have OIDs
1159 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
1163 *) Simplify the trust setting structure and code. Now we just have
1164 two sequences of OIDs for trusted and rejected settings. These will
1165 typically have values the same as the extended key usage extension
1166 and any application specific purposes.
1168 The trust checking code now has a default behaviour: it will just
1169 check for an object with the same NID as the passed id. Functions can
1170 be provided to override either the default behaviour or the behaviour
1171 for a given id. SSL client, server and email already have functions
1172 in place for compatibility: they check the NID and also return "trusted"
1173 if the certificate is self signed.
1176 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
1177 traditional format into an EVP_PKEY structure.
1180 *) Add a password callback function PEM_cb() which either prompts for
1181 a password if usr_data is NULL or otherwise assumes it is a null
1182 terminated password. Allow passwords to be passed on command line
1183 environment or config files in a few more utilities.
1186 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
1187 keys. Add some short names for PKCS#8 PBE algorithms and allow them
1188 to be specified on the command line for the pkcs8 and pkcs12 utilities.
1189 Update documentation.
1192 *) Support for ASN1 "NULL" type. This could be handled before by using
1193 ASN1_TYPE but there wasn't any function that would try to read a NULL
1194 and produce an error if it couldn't. For compatibility we also have
1195 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
1196 don't allocate anything because they don't need to.
1199 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
1201 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
1203 *) Rebuild of the memory allocation routines used by OpenSSL code and
1204 possibly others as well. The purpose is to make an interface that
1205 provide hooks so anyone can build a separate set of allocation and
1206 deallocation routines to be used by OpenSSL, for example memory
1207 pool implementations, or something else, which was previously hard
1208 since Malloc(), Realloc() and Free() were defined as macros having
1209 the values malloc, realloc and free, respectively (except for Win32
1210 compilations). The same is provided for memory debugging code.
1211 OpenSSL already comes with functionality to find memory leaks, but
1212 this gives people a chance to debug other memory problems.
1214 With these changes, a new set of functions and macros have appeared:
1216 CRYPTO_set_mem_debug_functions() [F]
1217 CRYPTO_get_mem_debug_functions() [F]
1218 CRYPTO_dbg_set_options() [F]
1219 CRYPTO_dbg_get_options() [F]
1220 CRYPTO_malloc_debug_init() [M]
1222 The memory debug functions are NULL by default, unless the library
1223 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
1224 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
1225 gives the standard debugging functions that come with OpenSSL) or
1226 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
1227 provided by the library user) must be used. When the standard
1228 debugging functions are used, CRYPTO_dbg_set_options can be used to
1229 request additional information:
1230 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
1231 the CRYPTO_MDEBUG_xxx macro when compiling the library.
1233 Also, things like CRYPTO_set_mem_functions will always give the
1234 expected result (the new set of functions is used for allocation
1235 and deallocation) at all times, regardless of platform and compiler
1238 To finish it up, some functions that were never use in any other
1239 way than through macros have a new API and new semantic:
1242 CRYPTO_dbg_realloc()
1245 All macros of value have retained their old syntax.
1246 [Richard Levitte and Bodo Moeller]
1248 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
1249 ordering of SMIMECapabilities wasn't in "strength order" and there
1250 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
1254 *) Some ASN1 types with illegal zero length encoding (INTEGER,
1255 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
1256 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
1258 *) Merge in my S/MIME library for OpenSSL. This provides a simple
1259 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
1260 functionality to handle multipart/signed properly) and a utility
1261 called 'smime' to call all this stuff. This is based on code I
1262 originally wrote for Celo who have kindly allowed it to be
1263 included in OpenSSL.
1266 *) Add variants des_set_key_checked and des_set_key_unchecked of
1267 des_set_key (aka des_key_sched). Global variable des_check_key
1268 decides which of these is called by des_set_key; this way
1269 des_check_key behaves as it always did, but applications and
1270 the library itself, which was buggy for des_check_key == 1,
1271 have a cleaner way to pick the version they need.
1274 *) New function PKCS12_newpass() which changes the password of a
1278 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
1279 dynamic mix. In both cases the ids can be used as an index into the
1280 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
1281 functions so they accept a list of the field values and the
1282 application doesn't need to directly manipulate the X509_TRUST
1286 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
1290 *) Modify the way the V3 extension code looks up extensions. This now
1291 works in a similar way to the object code: we have some "standard"
1292 extensions in a static table which is searched with OBJ_bsearch()
1293 and the application can add dynamic ones if needed. The file
1294 crypto/x509v3/ext_dat.h now has the info: this file needs to be
1295 updated whenever a new extension is added to the core code and kept
1296 in ext_nid order. There is a simple program 'tabtest.c' which checks
1297 this. New extensions are not added too often so this file can readily
1298 be maintained manually.
1300 There are two big advantages in doing things this way. The extensions
1301 can be looked up immediately and no longer need to be "added" using
1302 X509V3_add_standard_extensions(): this function now does nothing.
1303 [Side note: I get *lots* of email saying the extension code doesn't
1304 work because people forget to call this function]
1305 Also no dynamic allocation is done unless new extensions are added:
1306 so if we don't add custom extensions there is no need to call
1307 X509V3_EXT_cleanup().
1310 *) Modify enc utility's salting as follows: make salting the default. Add a
1311 magic header, so unsalted files fail gracefully instead of just decrypting
1312 to garbage. This is because not salting is a big security hole, so people
1313 should be discouraged from doing it.
1316 *) Fixes and enhancements to the 'x509' utility. It allowed a message
1317 digest to be passed on the command line but it only used this
1318 parameter when signing a certificate. Modified so all relevant
1319 operations are affected by the digest parameter including the
1320 -fingerprint and -x509toreq options. Also -x509toreq choked if a
1321 DSA key was used because it didn't fix the digest.
1324 *) Initial certificate chain verify code. Currently tests the untrusted
1325 certificates for consistency with the verify purpose (which is set
1326 when the X509_STORE_CTX structure is set up) and checks the pathlength.
1328 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
1329 this is because it will reject chains with invalid extensions whereas
1330 every previous version of OpenSSL and SSLeay made no checks at all.
1332 Trust code: checks the root CA for the relevant trust settings. Trust
1333 settings have an initial value consistent with the verify purpose: e.g.
1334 if the verify purpose is for SSL client use it expects the CA to be
1335 trusted for SSL client use. However the default value can be changed to
1336 permit custom trust settings: one example of this would be to only trust
1337 certificates from a specific "secure" set of CAs.
1339 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
1340 which should be used for version portability: especially since the
1341 verify structure is likely to change more often now.
1343 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
1344 to set them. If not set then assume SSL clients will verify SSL servers
1347 Two new options to the verify program: -untrusted allows a set of
1348 untrusted certificates to be passed in and -purpose which sets the
1349 intended purpose of the certificate. If a purpose is set then the
1350 new chain verify code is used to check extension consistency.
1353 *) Support for the authority information access extension.
1356 *) Modify RSA and DSA PEM read routines to transparently handle
1357 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
1358 public keys in a format compatible with certificate
1359 SubjectPublicKeyInfo structures. Unfortunately there were already
1360 functions called *_PublicKey_* which used various odd formats so
1361 these are retained for compatibility: however the DSA variants were
1362 never in a public release so they have been deleted. Changed dsa/rsa
1363 utilities to handle the new format: note no releases ever handled public
1364 keys so we should be OK.
1366 The primary motivation for this change is to avoid the same fiasco
1367 that dogs private keys: there are several incompatible private key
1368 formats some of which are standard and some OpenSSL specific and
1369 require various evil hacks to allow partial transparent handling and
1370 even then it doesn't work with DER formats. Given the option anything
1371 other than PKCS#8 should be dumped: but the other formats have to
1372 stay in the name of compatibility.
1374 With public keys and the benefit of hindsight one standard format
1375 is used which works with EVP_PKEY, RSA or DSA structures: though
1376 it clearly returns an error if you try to read the wrong kind of key.
1378 Added a -pubkey option to the 'x509' utility to output the public key.
1379 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
1380 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
1381 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
1382 that do the same as the EVP_PKEY_assign_*() except they up the
1383 reference count of the added key (they don't "swallow" the
1387 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
1388 CRLs would fail if the file contained no certificates or no CRLs:
1389 added a new function to read in both types and return the number
1390 read: this means that if none are read it will be an error. The
1391 DER versions of the certificate and CRL reader would always fail
1392 because it isn't possible to mix certificates and CRLs in DER format
1393 without choking one or the other routine. Changed this to just read
1394 a certificate: this is the best we can do. Also modified the code
1395 in apps/verify.c to take notice of return codes: it was previously
1396 attempting to read in certificates from NULL pointers and ignoring
1397 any errors: this is one reason why the cert and CRL reader seemed
1398 to work. It doesn't check return codes from the default certificate
1399 routines: these may well fail if the certificates aren't installed.
1402 *) Code to support otherName option in GeneralName.
1405 *) First update to verify code. Change the verify utility
1406 so it warns if it is passed a self signed certificate:
1407 for consistency with the normal behaviour. X509_verify
1408 has been modified to it will now verify a self signed
1409 certificate if *exactly* the same certificate appears
1410 in the store: it was previously impossible to trust a
1411 single self signed certificate. This means that:
1412 openssl verify ss.pem
1413 now gives a warning about a self signed certificate but
1414 openssl verify -CAfile ss.pem ss.pem
1418 *) For servers, store verify_result in SSL_SESSION data structure
1419 (and add it to external session representation).
1420 This is needed when client certificate verifications fails,
1421 but an application-provided verification callback (set by
1422 SSL_CTX_set_cert_verify_callback) allows accepting the session
1423 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
1424 but returns 1): When the session is reused, we have to set
1425 ssl->verify_result to the appropriate error code to avoid
1427 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
1429 *) Fix a bug in the new PKCS#7 code: it didn't consider the
1430 case in PKCS7_dataInit() where the signed PKCS7 structure
1431 didn't contain any existing data because it was being created.
1432 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
1434 *) Add a salt to the key derivation routines in enc.c. This
1435 forms the first 8 bytes of the encrypted file. Also add a
1436 -S option to allow a salt to be input on the command line.
1439 *) New function X509_cmp(). Oddly enough there wasn't a function
1440 to compare two certificates. We do this by working out the SHA1
1441 hash and comparing that. X509_cmp() will be needed by the trust
1445 *) SSL_get1_session() is like SSL_get_session(), but increments
1446 the reference count in the SSL_SESSION returned.
1447 [Geoff Thorpe <geoff@eu.c2.net>]
1449 *) Fix for 'req': it was adding a null to request attributes.
1450 Also change the X509_LOOKUP and X509_INFO code to handle
1451 certificate auxiliary information.
1454 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
1458 *) Add the possibility to add extra information to the memory leak
1459 detecting output, to form tracebacks, showing from where each
1460 allocation was originated: CRYPTO_push_info("constant string") adds
1461 the string plus current file name and line number to a per-thread
1462 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
1463 is like calling CYRPTO_pop_info() until the stack is empty.
1464 Also updated memory leak detection code to be multi-thread-safe.
1467 *) Add options -text and -noout to pkcs7 utility and delete the
1468 encryption options which never did anything. Update docs.
1471 *) Add options to some of the utilities to allow the pass phrase
1472 to be included on either the command line (not recommended on
1473 OSes like Unix) or read from the environment. Update the
1474 manpages and fix a few bugs.
1477 *) Add a few manpages for some of the openssl commands.
1480 *) Fix the -revoke option in ca. It was freeing up memory twice,
1481 leaking and not finding already revoked certificates.
1484 *) Extensive changes to support certificate auxiliary information.
1485 This involves the use of X509_CERT_AUX structure and X509_AUX
1486 functions. An X509_AUX function such as PEM_read_X509_AUX()
1487 can still read in a certificate file in the usual way but it
1488 will also read in any additional "auxiliary information". By
1489 doing things this way a fair degree of compatibility can be
1490 retained: existing certificates can have this information added
1491 using the new 'x509' options.
1493 Current auxiliary information includes an "alias" and some trust
1494 settings. The trust settings will ultimately be used in enhanced
1495 certificate chain verification routines: currently a certificate
1496 can only be trusted if it is self signed and then it is trusted
1500 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
1501 The problem was that one of the replacement routines had not been working
1502 since SSLeay releases. For now the offending routine has been replaced
1503 with non-optimised assembler. Even so, this now gives around 95%
1504 performance improvement for 1024 bit RSA signs.
1507 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
1508 handling. Most clients have the effective key size in bits equal to
1509 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
1510 A few however don't do this and instead use the size of the decrypted key
1511 to determine the RC2 key length and the AlgorithmIdentifier to determine
1512 the effective key length. In this case the effective key length can still
1513 be 40 bits but the key length can be 168 bits for example. This is fixed
1514 by manually forcing an RC2 key into the EVP_PKEY structure because the
1515 EVP code can't currently handle unusual RC2 key sizes: it always assumes
1516 the key length and effective key length are equal.
1519 *) Add a bunch of functions that should simplify the creation of
1520 X509_NAME structures. Now you should be able to do:
1521 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
1522 and have it automatically work out the correct field type and fill in
1523 the structures. The more adventurous can try:
1524 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
1525 and it will (hopefully) work out the correct multibyte encoding.
1528 *) Change the 'req' utility to use the new field handling and multibyte
1529 copy routines. Before the DN field creation was handled in an ad hoc
1530 way in req, ca, and x509 which was rather broken and didn't support
1531 BMPStrings or UTF8Strings. Since some software doesn't implement
1532 BMPStrings or UTF8Strings yet, they can be enabled using the config file
1533 using the dirstring_type option. See the new comment in the default
1534 openssl.cnf for more info.
1537 *) Make crypto/rand/md_rand.c more robust:
1538 - Assure unique random numbers after fork().
1539 - Make sure that concurrent threads access the global counter and
1540 md serializably so that we never lose entropy in them
1541 or use exactly the same state in multiple threads.
1542 Access to the large state is not always serializable because
1543 the additional locking could be a performance killer, and
1544 md should be large enough anyway.
1547 *) New file apps/app_rand.c with commonly needed functionality
1548 for handling the random seed file.
1550 Use the random seed file in some applications that previously did not:
1552 dsaparam -genkey (which also ignored its '-rand' option),
1555 x509 (when signing).
1556 Except on systems with /dev/urandom, it is crucial to have a random
1557 seed file at least for key creation, DSA signing, and for DH exchanges;
1558 for RSA signatures we could do without one.
1560 gendh and gendsa (unlike genrsa) used to read only the first byte
1561 of each file listed in the '-rand' option. The function as previously
1562 found in genrsa is now in app_rand.c and is used by all programs
1563 that support '-rand'.
1566 *) In RAND_write_file, use mode 0600 for creating files;
1567 don't just chmod when it may be too late.
1570 *) Report an error from X509_STORE_load_locations
1571 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
1574 *) New function ASN1_mbstring_copy() this copies a string in either
1575 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
1576 into an ASN1_STRING type. A mask of permissible types is passed
1577 and it chooses the "minimal" type to use or an error if not type
1581 *) Add function equivalents to the various macros in asn1.h. The old
1582 macros are retained with an M_ prefix. Code inside the library can
1583 use the M_ macros. External code (including the openssl utility)
1584 should *NOT* in order to be "shared library friendly".
1587 *) Add various functions that can check a certificate's extensions
1588 to see if it usable for various purposes such as SSL client,
1589 server or S/MIME and CAs of these types. This is currently
1590 VERY EXPERIMENTAL but will ultimately be used for certificate chain
1591 verification. Also added a -purpose flag to x509 utility to
1592 print out all the purposes.
1595 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
1599 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
1600 for, obtain and decode and extension and obtain its critical flag.
1601 This allows all the necessary extension code to be handled in a
1602 single function call.
1605 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
1606 platforms. See crypto/rc4/rc4_enc.c for further details.
1609 *) New -noout option to asn1parse. This causes no output to be produced
1610 its main use is when combined with -strparse and -out to extract data
1611 from a file (which may not be in ASN.1 format).
1614 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
1615 when producing the local key id.
1616 [Richard Levitte <levitte@stacken.kth.se>]
1618 *) New option -dhparam in s_server. This allows a DH parameter file to be
1619 stated explicitly. If it is not stated then it tries the first server
1620 certificate file. The previous behaviour hard coded the filename
1624 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
1625 a public key to be input or output. For example:
1626 openssl rsa -in key.pem -pubout -out pubkey.pem
1627 Also added necessary DSA public key functions to handle this.
1630 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
1631 in the message. This was handled by allowing
1632 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
1633 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
1635 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
1636 to the end of the strings whereas this didn't. This would cause problems
1637 if strings read with d2i_ASN1_bytes() were later modified.
1638 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
1640 *) Fix for base64 decode bug. When a base64 bio reads only one line of
1641 data and it contains EOF it will end up returning an error. This is
1642 caused by input 46 bytes long. The cause is due to the way base64
1643 BIOs find the start of base64 encoded data. They do this by trying a
1644 trial decode on each line until they find one that works. When they
1645 do a flag is set and it starts again knowing it can pass all the
1646 data directly through the decoder. Unfortunately it doesn't reset
1647 the context it uses. This means that if EOF is reached an attempt
1648 is made to pass two EOFs through the context and this causes the
1649 resulting error. This can also cause other problems as well. As is
1650 usual with these problems it takes *ages* to find and the fix is
1651 trivial: move one line.
1652 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
1654 *) Ugly workaround to get s_client and s_server working under Windows. The
1655 old code wouldn't work because it needed to select() on sockets and the
1656 tty (for keypresses and to see if data could be written). Win32 only
1657 supports select() on sockets so we select() with a 1s timeout on the
1658 sockets and then see if any characters are waiting to be read, if none
1659 are present then we retry, we also assume we can always write data to
1660 the tty. This isn't nice because the code then blocks until we've
1661 received a complete line of data and it is effectively polling the
1662 keyboard at 1s intervals: however it's quite a bit better than not
1663 working at all :-) A dedicated Windows application might handle this
1664 with an event loop for example.
1667 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
1668 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
1669 will be called when RSA_sign() and RSA_verify() are used. This is useful
1670 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
1671 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
1672 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
1673 This necessitated the support of an extra signature type NID_md5_sha1
1674 for SSL signatures and modifications to the SSL library to use it instead
1675 of calling RSA_public_decrypt() and RSA_private_encrypt().
1678 *) Add new -verify -CAfile and -CApath options to the crl program, these
1679 will lookup a CRL issuers certificate and verify the signature in a
1680 similar way to the verify program. Tidy up the crl program so it
1681 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
1682 less strict. It will now permit CRL extensions even if it is not
1683 a V2 CRL: this will allow it to tolerate some broken CRLs.
1686 *) Initialize all non-automatic variables each time one of the openssl
1687 sub-programs is started (this is necessary as they may be started
1688 multiple times from the "OpenSSL>" prompt).
1689 [Lennart Bang, Bodo Moeller]
1691 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
1692 removing all other RSA functionality (this is what NO_RSA does). This
1693 is so (for example) those in the US can disable those operations covered
1694 by the RSA patent while allowing storage and parsing of RSA keys and RSA
1698 *) Non-copying interface to BIO pairs.
1699 (still largely untested)
1702 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
1703 ASCII string. This was handled independently in various places before.
1706 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
1707 UTF8 strings a character at a time.
1710 *) Use client_version from client hello to select the protocol
1711 (s23_srvr.c) and for RSA client key exchange verification
1712 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
1715 *) Add various utility functions to handle SPKACs, these were previously
1716 handled by poking round in the structure internals. Added new function
1717 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
1718 print, verify and generate SPKACs. Based on an original idea from
1719 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
1722 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
1725 *) Allow the config file extension section to be overwritten on the
1726 command line. Based on an original idea from Massimiliano Pala
1727 <madwolf@comune.modena.it>. The new option is called -extensions
1728 and can be applied to ca, req and x509. Also -reqexts to override
1729 the request extensions in req and -crlexts to override the crl extensions
1733 *) Add new feature to the SPKAC handling in ca. Now you can include
1734 the same field multiple times by preceding it by "XXXX." for example:
1737 this is the same syntax as used in the req config file.
1740 *) Allow certificate extensions to be added to certificate requests. These
1741 are specified in a 'req_extensions' option of the req section of the
1742 config file. They can be printed out with the -text option to req but
1743 are otherwise ignored at present.
1746 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
1747 data read consists of only the final block it would not decrypted because
1748 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
1749 A misplaced 'break' also meant the decrypted final block might not be
1750 copied until the next read.
1753 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
1754 a few extra parameters to the DH structure: these will be useful if
1755 for example we want the value of 'q' or implement X9.42 DH.
1758 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
1759 provides hooks that allow the default DSA functions or functions on a
1760 "per key" basis to be replaced. This allows hardware acceleration and
1761 hardware key storage to be handled without major modification to the
1762 library. Also added low level modexp hooks and CRYPTO_EX structure and
1763 associated functions.
1766 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
1767 as "read only": it can't be written to and the buffer it points to will
1768 not be freed. Reading from a read only BIO is much more efficient than
1769 a normal memory BIO. This was added because there are several times when
1770 an area of memory needs to be read from a BIO. The previous method was
1771 to create a memory BIO and write the data to it, this results in two
1772 copies of the data and an O(n^2) reading algorithm. There is a new
1773 function BIO_new_mem_buf() which creates a read only memory BIO from
1774 an area of memory. Also modified the PKCS#7 routines to use read only
1778 *) Bugfix: ssl23_get_client_hello did not work properly when called in
1779 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
1780 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
1781 but a retry condition occured while trying to read the rest.
1784 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
1785 NID_pkcs7_encrypted by default: this was wrong since this should almost
1786 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
1787 the encrypted data type: this is a more sensible place to put it and it
1788 allows the PKCS#12 code to be tidied up that duplicated this
1792 *) Changed obj_dat.pl script so it takes its input and output files on
1793 the command line. This should avoid shell escape redirection problems
1797 *) Initial support for certificate extension requests, these are included
1798 in things like Xenroll certificate requests. Included functions to allow
1799 extensions to be obtained and added.
1802 *) -crlf option to s_client and s_server for sending newlines as
1803 CRLF (as required by many protocols).
1806 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
1808 *) Install libRSAglue.a when OpenSSL is built with RSAref.
1809 [Ralf S. Engelschall]
1811 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
1812 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
1814 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
1818 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
1819 DH parameters/keys (q is lost during that conversion, but the resulting
1820 DH parameters contain its length).
1822 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
1823 much faster than DH_generate_parameters (which creates parameters
1824 where p = 2*q + 1), and also the smaller q makes DH computations
1825 much more efficient (160-bit exponentiation instead of 1024-bit
1826 exponentiation); so this provides a convenient way to support DHE
1827 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
1828 utter importance to use
1829 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1831 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1832 when such DH parameters are used, because otherwise small subgroup
1833 attacks may become possible!
1836 *) Avoid memory leak in i2d_DHparams.
1839 *) Allow the -k option to be used more than once in the enc program:
1840 this allows the same encrypted message to be read by multiple recipients.
1843 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
1844 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
1845 it will always use the numerical form of the OID, even if it has a short
1849 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
1850 method only got called if p,q,dmp1,dmq1,iqmp components were present,
1851 otherwise bn_mod_exp was called. In the case of hardware keys for example
1852 no private key components need be present and it might store extra data
1853 in the RSA structure, which cannot be accessed from bn_mod_exp.
1854 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
1855 private key operations.
1858 *) Added support for SPARC Linux.
1861 *) pem_password_cb function type incompatibly changed from
1862 typedef int pem_password_cb(char *buf, int size, int rwflag);
1864 ....(char *buf, int size, int rwflag, void *userdata);
1865 so that applications can pass data to their callbacks:
1866 The PEM[_ASN1]_{read,write}... functions and macros now take an
1867 additional void * argument, which is just handed through whenever
1868 the password callback is called.
1869 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
1871 New function SSL_CTX_set_default_passwd_cb_userdata.
1873 Compatibility note: As many C implementations push function arguments
1874 onto the stack in reverse order, the new library version is likely to
1875 interoperate with programs that have been compiled with the old
1876 pem_password_cb definition (PEM_whatever takes some data that
1877 happens to be on the stack as its last argument, and the callback
1878 just ignores this garbage); but there is no guarantee whatsoever that
1881 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
1882 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
1883 problems not only on Windows, but also on some Unix platforms.
1884 To avoid problematic command lines, these definitions are now in an
1885 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
1886 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
1889 *) MIPS III/IV assembler module is reimplemented.
1892 *) More DES library cleanups: remove references to srand/rand and
1893 delete an unused file.
1896 *) Add support for the the free Netwide assembler (NASM) under Win32,
1897 since not many people have MASM (ml) and it can be hard to obtain.
1898 This is currently experimental but it seems to work OK and pass all
1899 the tests. Check out INSTALL.W32 for info.
1902 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
1903 without temporary keys kept an extra copy of the server key,
1904 and connections with temporary keys did not free everything in case
1908 *) New function RSA_check_key and new openssl rsa option -check
1909 for verifying the consistency of RSA keys.
1910 [Ulf Moeller, Bodo Moeller]
1912 *) Various changes to make Win32 compile work:
1913 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
1914 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
1915 comparison" warnings.
1916 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
1919 *) Add a debugging option to PKCS#5 v2 key generation function: when
1920 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
1921 derived keys are printed to stderr.
1924 *) Copy the flags in ASN1_STRING_dup().
1925 [Roman E. Pavlov <pre@mo.msk.ru>]
1927 *) The x509 application mishandled signing requests containing DSA
1928 keys when the signing key was also DSA and the parameters didn't match.
1930 It was supposed to omit the parameters when they matched the signing key:
1931 the verifying software was then supposed to automatically use the CA's
1932 parameters if they were absent from the end user certificate.
1934 Omitting parameters is no longer recommended. The test was also
1935 the wrong way round! This was probably due to unusual behaviour in
1936 EVP_cmp_parameters() which returns 1 if the parameters match.
1937 This meant that parameters were omitted when they *didn't* match and
1938 the certificate was useless. Certificates signed with 'ca' didn't have
1940 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
1942 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
1943 The interface is as follows:
1944 Applications can use
1945 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
1946 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
1947 "off" is now the default.
1948 The library internally uses
1949 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
1950 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
1951 to disable memory-checking temporarily.
1953 Some inconsistent states that previously were possible (and were
1954 even the default) are now avoided.
1956 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
1957 with each memory chunk allocated; this is occasionally more helpful
1958 than just having a counter.
1960 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
1962 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
1966 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
1967 which largely parallels "options", but is for changing API behaviour,
1968 whereas "options" are about protocol behaviour.
1969 Initial "mode" flags are:
1971 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
1972 a single record has been written.
1973 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
1974 retries use the same buffer location.
1975 (But all of the contents must be
1979 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
1982 *) Fix problems with no-hmac etc.
1983 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
1985 *) New functions RSA_get_default_method(), RSA_set_method() and
1986 RSA_get_method(). These allows replacement of RSA_METHODs without having
1987 to mess around with the internals of an RSA structure.
1990 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
1991 Also really enable memory leak checks in openssl.c and in some
1993 [Chad C. Mulligan, Bodo Moeller]
1995 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
1996 up the length of negative integers. This has now been simplified to just
1997 store the length when it is first determined and use it later, rather
1998 than trying to keep track of where data is copied and updating it to
2000 [Steve Henson, reported by Brien Wheeler
2001 <bwheeler@authentica-security.com>]
2003 *) Add a new function PKCS7_signatureVerify. This allows the verification
2004 of a PKCS#7 signature but with the signing certificate passed to the
2005 function itself. This contrasts with PKCS7_dataVerify which assumes the
2006 certificate is present in the PKCS#7 structure. This isn't always the
2007 case: certificates can be omitted from a PKCS#7 structure and be
2008 distributed by "out of band" means (such as a certificate database).
2011 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
2012 function prototypes in pem.h, also change util/mkdef.pl to add the
2013 necessary function names.
2016 *) mk1mf.pl (used by Windows builds) did not properly read the
2017 options set by Configure in the top level Makefile, and Configure
2018 was not even able to write more than one option correctly.
2019 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
2022 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
2023 file to be loaded from a BIO or FILE pointer. The BIO version will
2024 for example allow memory BIOs to contain config info.
2027 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
2028 Whoever hopes to achieve shared-library compatibility across versions
2029 must use this, not the compile-time macro.
2030 (Exercise 0.9.4: Which is the minimum library version required by
2032 Note: All this applies only to multi-threaded programs, others don't
2036 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
2037 through a BIO pair triggered the default case, i.e.
2038 SSLerr(...,SSL_R_UNKNOWN_STATE).
2041 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
2042 can use the SSL library even if none of the specific BIOs is
2046 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
2047 for the encoded length.
2048 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
2050 *) Add initial documentation of the X509V3 functions.
2053 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
2054 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
2055 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
2056 secure PKCS#8 private key format with a high iteration count.
2059 *) Fix determination of Perl interpreter: A perl or perl5
2060 _directory_ in $PATH was also accepted as the interpreter.
2061 [Ralf S. Engelschall]
2063 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
2064 wrong with it but it was very old and did things like calling
2065 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
2069 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
2070 to use the new extension code.
2073 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
2074 with macros. This should make it easier to change their form, add extra
2075 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
2079 *) Add to configuration table a new entry that can specify an alternative
2080 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
2081 according to Mark Crispin <MRC@Panda.COM>.
2085 *) DES CBC did not update the IV. Weird.
2088 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
2089 Changing the behaviour of the former might break existing programs --
2090 where IV updating is needed, des_ncbc_encrypt can be used.
2093 *) When bntest is run from "make test" it drives bc to check its
2094 calculations, as well as internally checking them. If an internal check
2095 fails, it needs to cause bc to give a non-zero result or make test carries
2096 on without noticing the failure. Fixed.
2099 *) DES library cleanups.
2102 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
2103 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
2104 ciphers. NOTE: although the key derivation function has been verified
2105 against some published test vectors it has not been extensively tested
2106 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
2110 *) Instead of "mkdir -p", which is not fully portable, use new
2111 Perl script "util/mkdir-p.pl".
2114 *) Rewrite the way password based encryption (PBE) is handled. It used to
2115 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
2116 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
2117 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
2118 the 'parameter' field of the AlgorithmIdentifier is passed to the
2119 underlying key generation function so it must do its own ASN1 parsing.
2120 This has also changed the EVP_PBE_CipherInit() function which now has a
2121 'parameter' argument instead of literal salt and iteration count values
2122 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
2125 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
2126 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
2127 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
2128 KEY" because this clashed with PKCS#8 unencrypted string. Since this
2129 value was just used as a "magic string" and not used directly its
2130 value doesn't matter.
2133 *) Introduce some semblance of const correctness to BN. Shame C doesn't
2137 *) "linux-sparc64" configuration (ultrapenguin).
2138 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
2139 "linux-sparc" configuration.
2140 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
2142 *) config now generates no-xxx options for missing ciphers.
2145 *) Support the EBCDIC character set (work in progress).
2146 File ebcdic.c not yet included because it has a different license.
2147 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2149 *) Support BS2000/OSD-POSIX.
2150 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2152 *) Make callbacks for key generation use void * instead of char *.
2155 *) Make S/MIME samples compile (not yet tested).
2158 *) Additional typesafe stacks.
2161 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
2165 Changes between 0.9.3 and 0.9.3a [29 May 1999]
2167 *) New configuration variant "sco5-gcc".
2169 *) Updated some demos.
2170 [Sean O Riordain, Wade Scholine]
2172 *) Add missing BIO_free at exit of pkcs12 application.
2175 *) Fix memory leak in conf.c.
2178 *) Updates for Win32 to assembler version of MD5.
2181 *) Set #! path to perl in apps/der_chop to where we found it
2182 instead of using a fixed path.
2185 *) SHA library changes for irix64-mips4-cc.
2188 *) Improvements for VMS support.
2192 Changes between 0.9.2b and 0.9.3 [24 May 1999]
2194 *) Bignum library bug fix. IRIX 6 passes "make test" now!
2195 This also avoids the problems with SC4.2 and unpatched SC5.
2196 [Andy Polyakov <appro@fy.chalmers.se>]
2198 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
2199 These are required because of the typesafe stack would otherwise break
2200 existing code. If old code used a structure member which used to be STACK
2201 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
2202 sk_num or sk_value it would produce an error because the num, data members
2203 are not present in STACK_OF. Now it just produces a warning. sk_set
2204 replaces the old method of assigning a value to sk_value
2205 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
2206 that does this will no longer work (and should use sk_set instead) but
2207 this could be regarded as a "questionable" behaviour anyway.
2210 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
2211 correctly handle encrypted S/MIME data.
2214 *) Change type of various DES function arguments from des_cblock
2215 (which means, in function argument declarations, pointer to char)
2216 to des_cblock * (meaning pointer to array with 8 char elements),
2217 which allows the compiler to do more typechecking; it was like
2218 that back in SSLeay, but with lots of ugly casts.
2220 Introduce new type const_des_cblock.
2223 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
2224 problems: find RecipientInfo structure that matches recipient certificate
2225 and initialise the ASN1 structures properly based on passed cipher.
2228 *) Belatedly make the BN tests actually check the results.
2231 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
2232 to and from BNs: it was completely broken. New compilation option
2233 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
2234 key elements as negative integers.
2237 *) Reorganize and speed up MD5.
2238 [Andy Polyakov <appro@fy.chalmers.se>]
2241 [Richard Levitte <richard@levitte.org>]
2243 *) New option -out to asn1parse to allow the parsed structure to be
2244 output to a file. This is most useful when combined with the -strparse
2245 option to examine the output of things like OCTET STRINGS.
2248 *) Make SSL library a little more fool-proof by not requiring any longer
2249 that SSL_set_{accept,connect}_state be called before
2250 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
2251 in many applications because usually everything *appeared* to work as
2252 intended anyway -- now it really works as intended).
2255 *) Move openssl.cnf out of lib/.
2258 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
2259 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
2260 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
2261 [Ralf S. Engelschall]
2263 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
2264 handle PKCS#7 enveloped data properly.
2265 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
2267 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
2268 copying pointers. The cert_st handling is changed by this in
2269 various ways (and thus what used to be known as ctx->default_cert
2270 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
2271 any longer when s->cert does not give us what we need).
2272 ssl_cert_instantiate becomes obsolete by this change.
2273 As soon as we've got the new code right (possibly it already is?),
2274 we have solved a couple of bugs of the earlier code where s->cert
2275 was used as if it could not have been shared with other SSL structures.
2277 Note that using the SSL API in certain dirty ways now will result
2278 in different behaviour than observed with earlier library versions:
2279 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
2280 does not influence s as it used to.
2282 In order to clean up things more thoroughly, inside SSL_SESSION
2283 we don't use CERT any longer, but a new structure SESS_CERT
2284 that holds per-session data (if available); currently, this is
2285 the peer's certificate chain and, for clients, the server's certificate
2286 and temporary key. CERT holds only those values that can have
2287 meaningful defaults in an SSL_CTX.
2290 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
2291 from the internal representation. Various PKCS#7 fixes: remove some
2292 evil casts and set the enc_dig_alg field properly based on the signing
2296 *) Allow PKCS#12 password to be set from the command line or the
2297 environment. Let 'ca' get its config file name from the environment
2298 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
2302 *) Allow certificate policies extension to use an IA5STRING for the
2303 organization field. This is contrary to the PKIX definition but
2304 VeriSign uses it and IE5 only recognises this form. Document 'x509'
2308 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
2309 without disallowing inline assembler and the like for non-pedantic builds.
2312 *) Support Borland C++ builder.
2313 [Janez Jere <jj@void.si>, modified by Ulf Möller]
2318 *) SHA-1 cleanups and performance enhancements.
2319 [Andy Polyakov <appro@fy.chalmers.se>]
2321 *) Sparc v8plus assembler for the bignum library.
2322 [Andy Polyakov <appro@fy.chalmers.se>]
2324 *) Accept any -xxx and +xxx compiler options in Configure.
2327 *) Update HPUX configuration.
2330 *) Add missing sk_<type>_unshift() function to safestack.h
2331 [Ralf S. Engelschall]
2333 *) New function SSL_CTX_use_certificate_chain_file that sets the
2334 "extra_cert"s in addition to the certificate. (This makes sense
2335 only for "PEM" format files, as chains as a whole are not
2339 *) Support verify_depth from the SSL API.
2340 x509_vfy.c had what can be considered an off-by-one-error:
2341 Its depth (which was not part of the external interface)
2342 was actually counting the number of certificates in a chain;
2343 now it really counts the depth.
2346 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
2347 instead of X509err, which often resulted in confusing error
2348 messages since the error codes are not globally unique
2349 (e.g. an alleged error in ssl3_accept when a certificate
2350 didn't match the private key).
2352 *) New function SSL_CTX_set_session_id_context that allows to set a default
2353 value (so that you don't need SSL_set_session_id_context for each
2354 connection using the SSL_CTX).
2357 *) OAEP decoding bug fix.
2360 *) Support INSTALL_PREFIX for package builders, as proposed by
2364 *) New Configure options "threads" and "no-threads". For systems
2365 where the proper compiler options are known (currently Solaris
2366 and Linux), "threads" is the default.
2369 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
2372 *) Install various scripts to $(OPENSSLDIR)/misc, not to
2373 $(INSTALLTOP)/bin -- they shouldn't clutter directories
2374 such as /usr/local/bin.
2377 *) "make linux-shared" to build shared libraries.
2378 [Niels Poppe <niels@netbox.org>]
2380 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
2383 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
2384 extension adding in x509 utility.
2387 *) Remove NOPROTO sections and error code comments.
2390 *) Partial rewrite of the DEF file generator to now parse the ANSI
2394 *) New Configure options --prefix=DIR and --openssldir=DIR.
2397 *) Complete rewrite of the error code script(s). It is all now handled
2398 by one script at the top level which handles error code gathering,
2399 header rewriting and C source file generation. It should be much better
2400 than the old method: it now uses a modified version of Ulf's parser to
2401 read the ANSI prototypes in all header files (thus the old K&R definitions
2402 aren't needed for error creation any more) and do a better job of
2403 translating function codes into names. The old 'ASN1 error code imbedded
2404 in a comment' is no longer necessary and it doesn't use .err files which
2405 have now been deleted. Also the error code call doesn't have to appear all
2406 on one line (which resulted in some large lines...).
2409 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
2412 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
2413 0 (which usually indicates a closed connection), but continue reading.
2416 *) Fix some race conditions.
2419 *) Add support for CRL distribution points extension. Add Certificate
2420 Policies and CRL distribution points documentation.
2423 *) Move the autogenerated header file parts to crypto/opensslconf.h.
2426 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
2427 8 of keying material. Merlin has also confirmed interop with this fix
2428 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
2429 [Merlin Hughes <merlin@baltimore.ie>]
2431 *) Fix lots of warnings.
2432 [Richard Levitte <levitte@stacken.kth.se>]
2434 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
2435 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
2436 [Richard Levitte <levitte@stacken.kth.se>]
2438 *) Fix problems with sizeof(long) == 8.
2439 [Andy Polyakov <appro@fy.chalmers.se>]
2441 *) Change functions to ANSI C.
2444 *) Fix typos in error codes.
2445 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
2447 *) Remove defunct assembler files from Configure.
2450 *) SPARC v8 assembler BIGNUM implementation.
2451 [Andy Polyakov <appro@fy.chalmers.se>]
2453 *) Support for Certificate Policies extension: both print and set.
2454 Various additions to support the r2i method this uses.
2457 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
2458 return a const string when you are expecting an allocated buffer.
2461 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
2462 types DirectoryString and DisplayText.
2465 *) Add code to allow r2i extensions to access the configuration database,
2466 add an LHASH database driver and add several ctx helper functions.
2469 *) Fix an evil bug in bn_expand2() which caused various BN functions to
2470 fail when they extended the size of a BIGNUM.
2473 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
2474 support typesafe stack.
2477 *) Fix typo in SSL_[gs]et_options().
2478 [Nils Frostberg <nils@medcom.se>]
2480 *) Delete various functions and files that belonged to the (now obsolete)
2481 old X509V3 handling code.
2484 *) New Configure option "rsaref".
2487 *) Don't auto-generate pem.h.
2490 *) Introduce type-safe ASN.1 SETs.
2493 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
2494 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
2496 *) Introduce type-safe STACKs. This will almost certainly break lots of code
2497 that links with OpenSSL (well at least cause lots of warnings), but fear
2498 not: the conversion is trivial, and it eliminates loads of evil casts. A
2499 few STACKed things have been converted already. Feel free to convert more.
2500 In the fullness of time, I'll do away with the STACK type altogether.
2503 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
2504 specified in <certfile> by updating the entry in the index.txt file.
2505 This way one no longer has to edit the index.txt file manually for
2506 revoking a certificate. The -revoke option does the gory details now.
2507 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
2509 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
2510 `-text' option at all and this way the `-noout -text' combination was
2511 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
2512 [Ralf S. Engelschall]
2514 *) Make sure a corresponding plain text error message exists for the
2515 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
2516 verify callback function determined that a certificate was revoked.
2517 [Ralf S. Engelschall]
2519 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
2520 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
2521 all available cipers including rc5, which was forgotten until now.
2522 In order to let the testing shell script know which algorithms
2523 are available, a new (up to now undocumented) command
2524 "openssl list-cipher-commands" is used.
2527 *) Bugfix: s_client occasionally would sleep in select() when
2528 it should have checked SSL_pending() first.
2531 *) New functions DSA_do_sign and DSA_do_verify to provide access to
2532 the raw DSA values prior to ASN.1 encoding.
2535 *) Tweaks to Configure
2536 [Niels Poppe <niels@netbox.org>]
2538 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
2542 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
2545 *) New config option to avoid instructions that are illegal on the 80386.
2546 The default code is faster, but requires at least a 486.
2549 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
2550 SSL2_SERVER_VERSION (not used at all) macros, which are now the
2551 same as SSL2_VERSION anyway.
2554 *) New "-showcerts" option for s_client.
2557 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
2558 application. Various cleanups and fixes.
2561 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
2562 modify error routines to work internally. Add error codes and PBE init
2563 to library startup routines.
2566 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
2567 packing functions to asn1 and evp. Changed function names and error
2568 codes along the way.
2571 *) PKCS12 integration: and so it begins... First of several patches to
2572 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
2573 objects to objects.h
2576 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
2577 and display support for Thawte strong extranet extension.
2580 *) Add LinuxPPC support.
2581 [Jeff Dubrule <igor@pobox.org>]
2583 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
2584 bn_div_words in alpha.s.
2585 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
2587 *) Make sure the RSA OAEP test is skipped under -DRSAref because
2588 OAEP isn't supported when OpenSSL is built with RSAref.
2589 [Ulf Moeller <ulf@fitug.de>]
2591 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
2592 so they no longer are missing under -DNOPROTO.
2593 [Soren S. Jorvang <soren@t.dk>]
2596 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
2598 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
2599 doesn't work when the session is reused. Coming soon!
2602 *) Fix a security hole, that allows sessions to be reused in the wrong
2603 context thus bypassing client cert protection! All software that uses
2604 client certs and session caches in multiple contexts NEEDS PATCHING to
2605 allow session reuse! A fuller solution is in the works.
2606 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
2608 *) Some more source tree cleanups (removed obsolete files
2609 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
2610 permission on "config" script to be executable) and a fix for the INSTALL
2612 [Ulf Moeller <ulf@fitug.de>]
2614 *) Remove some legacy and erroneous uses of malloc, free instead of
2616 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
2618 *) Make rsa_oaep_test return non-zero on error.
2619 [Ulf Moeller <ulf@fitug.de>]
2621 *) Add support for native Solaris shared libraries. Configure
2622 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
2623 if someone would make that last step automatic.
2624 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
2626 *) ctx_size was not built with the right compiler during "make links". Fixed.
2629 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
2630 except NULL ciphers". This means the default cipher list will no longer
2631 enable NULL ciphers. They need to be specifically enabled e.g. with
2632 the string "DEFAULT:eNULL".
2635 *) Fix to RSA private encryption routines: if p < q then it would
2636 occasionally produce an invalid result. This will only happen with
2637 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
2640 *) Be less restrictive and allow also `perl util/perlpath.pl
2641 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
2642 because this way one can also use an interpreter named `perl5' (which is
2643 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
2644 installed as `perl').
2645 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2647 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
2648 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2650 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
2651 advapi32.lib to Win32 build and change the pem test comparision
2652 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
2653 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
2654 and crypto/des/ede_cbcm_enc.c.
2657 *) DES quad checksum was broken on big-endian architectures. Fixed.
2660 *) Comment out two functions in bio.h that aren't implemented. Fix up the
2661 Win32 test batch file so it (might) work again. The Win32 test batch file
2662 is horrible: I feel ill....
2665 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
2666 in e_os.h. Audit of header files to check ANSI and non ANSI
2667 sections: 10 functions were absent from non ANSI section and not exported
2668 from Windows DLLs. Fixed up libeay.num for new functions.
2671 *) Make `openssl version' output lines consistent.
2672 [Ralf S. Engelschall]
2674 *) Fix Win32 symbol export lists for BIO functions: Added
2675 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
2676 to ms/libeay{16,32}.def.
2677 [Ralf S. Engelschall]
2679 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
2680 fine under Unix and passes some trivial tests I've now added. But the
2681 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
2682 added to make sure no one expects that this stuff really works in the
2683 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
2684 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
2686 [Ralf S. Engelschall]
2688 *) Fix the generation of two part addresses in perl.
2689 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
2691 *) Add config entry for Linux on MIPS.
2692 [John Tobey <jtobey@channel1.com>]
2694 *) Make links whenever Configure is run, unless we are on Windoze.
2697 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
2698 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
2702 *) Add a useful kludge to allow package maintainers to specify compiler and
2703 other platforms details on the command line without having to patch the
2704 Configure script everytime: One now can use ``perl Configure
2705 <id>:<details>'', i.e. platform ids are allowed to have details appended
2706 to them (seperated by colons). This is treated as there would be a static
2707 pre-configured entry in Configure's %table under key <id> with value
2708 <details> and ``perl Configure <id>'' is called. So, when you want to
2709 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
2710 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
2711 now, which overrides the FreeBSD-elf entry on-the-fly.
2712 [Ralf S. Engelschall]
2714 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
2717 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
2718 on the `perl Configure ...' command line. This way one can compile
2719 OpenSSL libraries with Position Independent Code (PIC) which is needed
2720 for linking it into DSOs.
2721 [Ralf S. Engelschall]
2723 *) Remarkably, export ciphers were totally broken and no-one had noticed!
2727 *) Cleaned up the LICENSE document: The official contact for any license
2728 questions now is the OpenSSL core team under openssl-core@openssl.org.
2729 And add a paragraph about the dual-license situation to make sure people
2730 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
2731 to the OpenSSL toolkit.
2732 [Ralf S. Engelschall]
2734 *) General source tree makefile cleanups: Made `making xxx in yyy...'
2735 display consistent in the source tree and replaced `/bin/rm' by `rm'.
2736 Additonally cleaned up the `make links' target: Remove unnecessary
2737 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
2738 to speed processing and no longer clutter the display with confusing
2739 stuff. Instead only the actually done links are displayed.
2740 [Ralf S. Engelschall]
2742 *) Permit null encryption ciphersuites, used for authentication only. It used
2743 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
2744 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
2748 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
2749 signed attributes when verifying signatures (this would break them),
2750 the detached data encoding was wrong and public keys obtained using
2751 X509_get_pubkey() weren't freed.
2754 *) Add text documentation for the BUFFER functions. Also added a work around
2755 to a Win95 console bug. This was triggered by the password read stuff: the
2756 last character typed gets carried over to the next fread(). If you were
2757 generating a new cert request using 'req' for example then the last
2758 character of the passphrase would be CR which would then enter the first
2762 *) Added the new `Includes OpenSSL Cryptography Software' button as
2763 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
2764 button and can be used by applications based on OpenSSL to show the
2765 relationship to the OpenSSL project.
2766 [Ralf S. Engelschall]
2768 *) Remove confusing variables in function signatures in files
2769 ssl/ssl_lib.c and ssl/ssl.h.
2770 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2772 *) Don't install bss_file.c under PREFIX/include/
2773 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2775 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
2776 functions that return function pointers and has support for NT specific
2777 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
2778 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
2779 unsigned to signed types: this was killing the Win32 compile.
2782 *) Add new certificate file to stack functions,
2783 SSL_add_dir_cert_subjects_to_stack() and
2784 SSL_add_file_cert_subjects_to_stack(). These largely supplant
2785 SSL_load_client_CA_file(), and can be used to add multiple certs easily
2786 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
2787 This means that Apache-SSL and similar packages don't have to mess around
2788 to add as many CAs as they want to the preferred list.
2791 *) Experiment with doxygen documentation. Currently only partially applied to
2793 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
2794 openssl.doxy as the configuration file.
2797 *) Get rid of remaining C++-style comments which strict C compilers hate.
2798 [Ralf S. Engelschall, pointed out by Carlos Amengual]
2800 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
2801 compiled in by default: it has problems with large keys.
2804 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
2805 DH private keys and/or callback functions which directly correspond to
2806 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
2807 is needed for applications which have to configure certificates on a
2808 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
2810 For the RSA certificate situation is makes no difference, but
2811 for the DSA certificate situation this fixes the "no shared cipher"
2812 problem where the OpenSSL cipher selection procedure failed because the
2813 temporary keys were not overtaken from the context and the API provided
2814 no way to reconfigure them.
2815 The new functions now let applications reconfigure the stuff and they
2816 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
2817 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
2818 non-public-API function ssl_cert_instantiate() is used as a helper
2819 function and also to reduce code redundancy inside ssl_rsa.c.
2820 [Ralf S. Engelschall]
2822 *) Move s_server -dcert and -dkey options out of the undocumented feature
2823 area because they are useful for the DSA situation and should be
2824 recognized by the users.
2825 [Ralf S. Engelschall]
2827 *) Fix the cipher decision scheme for export ciphers: the export bits are
2828 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
2829 SSL_EXP_MASK. So, the original variable has to be used instead of the
2830 already masked variable.
2831 [Richard Levitte <levitte@stacken.kth.se>]
2833 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
2834 [Richard Levitte <levitte@stacken.kth.se>]
2836 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
2837 from `int' to `unsigned int' because it's a length and initialized by
2838 EVP_DigestFinal() which expects an `unsigned int *'.
2839 [Richard Levitte <levitte@stacken.kth.se>]
2841 *) Don't hard-code path to Perl interpreter on shebang line of Configure
2842 script. Instead use the usual Shell->Perl transition trick.
2843 [Ralf S. Engelschall]
2845 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
2846 (in addition to RSA certificates) to match the behaviour of `openssl dsa
2847 -noout -modulus' as it's already the case for `openssl rsa -noout
2848 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
2849 currently the public key is printed (a decision which was already done by
2850 `openssl dsa -modulus' in the past) which serves a similar purpose.
2851 Additionally the NO_RSA no longer completely removes the whole -modulus
2852 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
2854 [Ralf S. Engelschall]
2856 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
2857 BIO. See the source (crypto/evp/bio_ok.c) for more info.
2858 [Arne Ansper <arne@ats.cyber.ee>]
2860 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
2861 to be added. Now both 'req' and 'ca' can use new objects defined in the
2865 *) Add cool BIO that does syslog (or event log on NT).
2866 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
2868 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
2869 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
2870 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
2871 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
2874 *) Add preliminary config info for new extension code.
2877 *) Make RSA_NO_PADDING really use no padding.
2878 [Ulf Moeller <ulf@fitug.de>]
2880 *) Generate errors when private/public key check is done.
2883 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
2884 for some CRL extensions and new objects added.
2887 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
2888 key usage extension and fuller support for authority key id.
2891 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
2892 padding method for RSA, which is recommended for new applications in PKCS
2893 #1 v2.0 (RFC 2437, October 1998).
2894 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
2895 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
2896 against Bleichbacher's attack on RSA.
2897 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
2900 *) Updates to the new SSL compression code
2901 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2903 *) Fix so that the version number in the master secret, when passed
2904 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
2905 (because the server will not accept higher), that the version number
2906 is 0x03,0x01, not 0x03,0x00
2907 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2909 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
2910 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
2911 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
2914 *) Support for RAW extensions where an arbitrary extension can be
2915 created by including its DER encoding. See apps/openssl.cnf for
2919 *) Make sure latest Perl versions don't interpret some generated C array
2920 code as Perl array code in the crypto/err/err_genc.pl script.
2921 [Lars Weber <3weber@informatik.uni-hamburg.de>]
2923 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
2924 not many people have the assembler. Various Win32 compilation fixes and
2925 update to the INSTALL.W32 file with (hopefully) more accurate Win32
2929 *) Modify configure script 'Configure' to automatically create crypto/date.h
2930 file under Win32 and also build pem.h from pem.org. New script
2931 util/mkfiles.pl to create the MINFO file on environments that can't do a
2932 'make files': perl util/mkfiles.pl >MINFO should work.
2935 *) Major rework of DES function declarations, in the pursuit of correctness
2936 and purity. As a result, many evil casts evaporated, and some weirdness,
2937 too. You may find this causes warnings in your code. Zapping your evil
2938 casts will probably fix them. Mostly.
2941 *) Fix for a typo in asn1.h. Bug fix to object creation script
2942 obj_dat.pl. It considered a zero in an object definition to mean
2943 "end of object": none of the objects in objects.h have any zeros
2944 so it wasn't spotted.
2945 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
2947 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
2948 Masking (CBCM). In the absence of test vectors, the best I have been able
2949 to do is check that the decrypt undoes the encrypt, so far. Send me test
2950 vectors if you have them.
2953 *) Correct calculation of key length for export ciphers (too much space was
2954 allocated for null ciphers). This has not been tested!
2957 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
2958 message is now correct (it understands "crypto" and "ssl" on its
2959 command line). There is also now an "update" option. This will update
2960 the util/ssleay.num and util/libeay.num files with any new functions.
2962 perl util/mkdef.pl crypto ssl update
2963 it will update them.
2966 *) Overhauled the Perl interface (perl/*):
2967 - ported BN stuff to OpenSSL's different BN library
2968 - made the perl/ source tree CVS-aware
2969 - renamed the package from SSLeay to OpenSSL (the files still contain
2970 their history because I've copied them in the repository)
2971 - removed obsolete files (the test scripts will be replaced
2972 by better Test::Harness variants in the future)
2973 [Ralf S. Engelschall]
2975 *) First cut for a very conservative source tree cleanup:
2976 1. merge various obsolete readme texts into doc/ssleay.txt
2977 where we collect the old documents and readme texts.
2978 2. remove the first part of files where I'm already sure that we no
2979 longer need them because of three reasons: either they are just temporary
2980 files which were left by Eric or they are preserved original files where
2981 I've verified that the diff is also available in the CVS via "cvs diff
2982 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
2983 the crypto/md/ stuff).
2984 [Ralf S. Engelschall]
2986 *) More extension code. Incomplete support for subject and issuer alt
2987 name, issuer and authority key id. Change the i2v function parameters
2988 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
2989 what that's for :-) Fix to ASN1 macro which messed up
2990 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
2993 *) Preliminary support for ENUMERATED type. This is largely copied from the
2997 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
2998 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3000 *) Make sure `make rehash' target really finds the `openssl' program.
3001 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3003 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
3004 like to hear about it if this slows down other processors.
3007 *) Add CygWin32 platform information to Configure script.
3008 [Alan Batie <batie@aahz.jf.intel.com>]
3010 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
3011 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
3013 *) New program nseq to manipulate netscape certificate sequences
3016 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
3020 *) Fixes to BN code. Previously the default was to define BN_RECURSION
3021 but the BN code had some problems that would cause failures when
3022 doing certificate verification and some other functions.
3023 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3025 *) Add ASN1 and PEM code to support netscape certificate sequences.
3028 *) Add ASN1 and PEM code to support netscape certificate sequences.
3031 *) Add several PKIX and private extended key usage OIDs.
3034 *) Modify the 'ca' program to handle the new extension code. Modify
3035 openssl.cnf for new extension format, add comments.
3038 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
3039 and add a sample to openssl.cnf so req -x509 now adds appropriate
3043 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
3044 error code, add initial support to X509_print() and x509 application.
3047 *) Takes a deep breath and start addding X509 V3 extension support code. Add
3048 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
3049 stuff is currently isolated and isn't even compiled yet.
3052 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
3053 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
3054 Removed the versions check from X509 routines when loading extensions:
3055 this allows certain broken certificates that don't set the version
3056 properly to be processed.
3059 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
3060 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
3061 can still be regenerated with "make depend".
3064 *) Spelling mistake in C version of CAST-128.
3065 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
3067 *) Changes to the error generation code. The perl script err-code.pl
3068 now reads in the old error codes and retains the old numbers, only
3069 adding new ones if necessary. It also only changes the .err files if new
3070 codes are added. The makefiles have been modified to only insert errors
3071 when needed (to avoid needlessly modifying header files). This is done
3072 by only inserting errors if the .err file is newer than the auto generated
3073 C file. To rebuild all the error codes from scratch (the old behaviour)
3074 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
3075 or delete all the .err files.
3078 *) CAST-128 was incorrectly implemented for short keys. The C version has
3079 been fixed, but is untested. The assembler versions are also fixed, but
3080 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
3081 to regenerate it if needed.
3082 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
3083 Hagino <itojun@kame.net>]
3085 *) File was opened incorrectly in randfile.c.
3086 [Ulf Möller <ulf@fitug.de>]
3088 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
3089 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
3090 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
3091 al: it's just almost always a UTCTime. Note this patch adds new error
3092 codes so do a "make errors" if there are problems.
3095 *) Correct Linux 1 recognition in config.
3096 [Ulf Möller <ulf@fitug.de>]
3098 *) Remove pointless MD5 hash when using DSA keys in ca.
3099 [Anonymous <nobody@replay.com>]
3101 *) Generate an error if given an empty string as a cert directory. Also
3102 generate an error if handed NULL (previously returned 0 to indicate an
3103 error, but didn't set one).
3104 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
3106 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
3109 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
3110 parameters. This was causing a warning which killed off the Win32 compile.
3113 *) Remove C++ style comments from crypto/bn/bn_local.h.
3114 [Neil Costigan <neil.costigan@celocom.com>]
3116 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
3117 based on a text string, looking up short and long names and finally
3118 "dot" format. The "dot" format stuff didn't work. Added new function
3119 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
3120 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
3121 OID is not part of the table.
3124 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
3125 X509_LOOKUP_by_alias().
3128 *) Sort openssl functions by name.
3131 *) Get the gendsa program working (hopefully) and add it to app list. Remove
3132 encryption from sample DSA keys (in case anyone is interested the password
3136 *) Make _all_ *_free functions accept a NULL pointer.
3137 [Frans Heymans <fheymans@isaserver.be>]
3139 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
3141 [Anonymous <nobody@replay.com>]
3143 *) s_server should send the CAfile as acceptable CAs, not its own cert.
3144 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3146 *) Don't blow it for numeric -newkey arguments to apps/req.
3147 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3149 *) Temp key "for export" tests were wrong in s3_srvr.c.
3150 [Anonymous <nobody@replay.com>]
3152 *) Add prototype for temp key callback functions
3153 SSL_CTX_set_tmp_{rsa,dh}_callback().
3156 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
3157 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
3160 *) X509_name_add_entry() freed the wrong thing after an error.
3161 [Arne Ansper <arne@ats.cyber.ee>]
3163 *) rsa_eay.c would attempt to free a NULL context.
3164 [Arne Ansper <arne@ats.cyber.ee>]
3166 *) BIO_s_socket() had a broken should_retry() on Windoze.
3167 [Arne Ansper <arne@ats.cyber.ee>]
3169 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
3170 [Arne Ansper <arne@ats.cyber.ee>]
3172 *) Make sure the already existing X509_STORE->depth variable is initialized
3173 in X509_STORE_new(), but document the fact that this variable is still
3174 unused in the certificate verification process.
3175 [Ralf S. Engelschall]
3177 *) Fix the various library and apps files to free up pkeys obtained from
3178 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
3181 *) Fix reference counting in X509_PUBKEY_get(). This makes
3182 demos/maurice/example2.c work, amongst others, probably.
3183 [Steve Henson and Ben Laurie]
3185 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
3186 `openssl' and second, the shortcut symlinks for the `openssl <command>'
3187 are no longer created. This way we have a single and consistent command
3188 line interface `openssl <command>', similar to `cvs <command>'.
3189 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
3191 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
3192 BIT STRING wrapper always have zero unused bits.
3195 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
3198 *) Make the top-level INSTALL documentation easier to understand.
3201 *) Makefiles updated to exit if an error occurs in a sub-directory
3202 make (including if user presses ^C) [Paul Sutton]
3204 *) Make Montgomery context stuff explicit in RSA data structure.
3207 *) Fix build order of pem and err to allow for generated pem.h.
3210 *) Fix renumbering bug in X509_NAME_delete_entry().
3213 *) Enhanced the err-ins.pl script so it makes the error library number
3214 global and can add a library name. This is needed for external ASN1 and
3215 other error libraries.
3218 *) Fixed sk_insert which never worked properly.
3221 *) Fix ASN1 macros so they can handle indefinite length construted
3222 EXPLICIT tags. Some non standard certificates use these: they can now
3226 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
3227 into a single doc/ssleay.txt bundle. This way the information is still
3228 preserved but no longer messes up this directory. Now it's new room for
3229 the new set of documenation files.
3230 [Ralf S. Engelschall]
3232 *) SETs were incorrectly DER encoded. This was a major pain, because they
3233 shared code with SEQUENCEs, which aren't coded the same. This means that
3234 almost everything to do with SETs or SEQUENCEs has either changed name or
3235 number of arguments.
3236 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
3238 *) Fix test data to work with the above.
3241 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
3242 was already fixed by Eric for 0.9.1 it seems.
3243 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
3245 *) Autodetect FreeBSD3.
3248 *) Fix various bugs in Configure. This affects the following platforms:
3252 unixware-2.0-pentium
3256 *) Eliminate generated files from CVS. Reorder tests to regenerate files
3257 before they are needed.
3260 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
3264 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
3266 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
3267 changed SSLeay to OpenSSL in version strings.
3268 [Ralf S. Engelschall]
3270 *) Some fixups to the top-level documents.
3273 *) Fixed the nasty bug where rsaref.h was not found under compile-time
3274 because the symlink to include/ was missing.
3275 [Ralf S. Engelschall]
3277 *) Incorporated the popular no-RSA/DSA-only patches
3278 which allow to compile a RSA-free SSLeay.
3279 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
3281 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
3282 when "ssleay" is still not found.
3283 [Ralf S. Engelschall]
3285 *) Added more platforms to Configure: Cray T3E, HPUX 11,
3286 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
3288 *) Updated the README file.
3289 [Ralf S. Engelschall]
3291 *) Added various .cvsignore files in the CVS repository subdirs
3292 to make a "cvs update" really silent.
3293 [Ralf S. Engelschall]
3295 *) Recompiled the error-definition header files and added
3296 missing symbols to the Win32 linker tables.
3297 [Ralf S. Engelschall]
3299 *) Cleaned up the top-level documents;
3300 o new files: CHANGES and LICENSE
3301 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
3302 o merged COPYRIGHT into LICENSE
3303 o removed obsolete TODO file
3304 o renamed MICROSOFT to INSTALL.W32
3305 [Ralf S. Engelschall]
3307 *) Removed dummy files from the 0.9.1b source tree:
3308 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
3309 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
3310 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f

3312 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
3313 [Ralf S. Engelschall]
3315 *) Added various platform portability fixes.
3318 *) The Genesis of the OpenSSL rpject:
3319 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
3320 Young and Tim J. Hudson created while they were working for C2Net until
3322 [The OpenSSL Project]
3325 Changes between 0.9.0b and 0.9.1b [not released]
3327 *) Updated a few CA certificates under certs/
3330 *) Changed some BIGNUM api stuff.
3333 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
3334 DGUX x86, Linux Alpha, etc.
3337 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
3338 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
3342 *) Add -strparse option to asn1pars program which parses nested
3344 [Dr Stephen Henson <shenson@bigfoot.com>]
3346 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
3349 *) DSA fix for "ca" program.
3352 *) Added "-genkey" option to "dsaparam" program.
3355 *) Added RIPE MD160 (rmd160) message digest.
3358 *) Added -a (all) option to "ssleay version" command.
3361 *) Added PLATFORM define which is the id given to Configure.
3364 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
3367 *) Extended the ASN.1 parser routines.
3370 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
3373 *) Added a BN_CTX to the BN library.
3376 *) Fixed the weak key values in DES library
3379 *) Changed API in EVP library for cipher aliases.
3382 *) Added support for RC2/64bit cipher.
3385 *) Converted the lhash library to the crypto/mem.c functions.
3388 *) Added more recognized ASN.1 object ids.
3391 *) Added more RSA padding checks for SSL/TLS.
3394 *) Added BIO proxy/filter functionality.
3397 *) Added extra_certs to SSL_CTX which can be used
3398 send extra CA certificates to the client in the CA cert chain sending
3399 process. It can be configured with SSL_CTX_add_extra_chain_cert().
3402 *) Now Fortezza is denied in the authentication phase because
3403 this is key exchange mechanism is not supported by SSLeay at all.
3406 *) Additional PKCS1 checks.
3409 *) Support the string "TLSv1" for all TLS v1 ciphers.
3412 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
3413 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
3416 *) Fixed a few memory leaks.
3419 *) Fixed various code and comment typos.
3422 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
3423 bytes sent in the client random.
