5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) New -noout option to asn1parse. This causes no output to be produced
8 its main use is when combined with -strparse and -out to extract data
9 from a file (which may not be in ASN.1 format).
12 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
13 when producing the local key id.
14 [Richard Levitte <levitte@stacken.kth.se>]
16 *) New option -dhparam in s_server. This allows a DH parameter file to be
17 stated explicitly. If it is not stated then it tries the first server
18 certificate file. The previous behaviour hard coded the filename
22 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
23 a public key to be input or output. For example:
24 openssl rsa -in key.pem -pubout -out pubkey.pem
25 Also added necessary DSA public key functions to handle this.
28 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
29 in the message. This was handled by allowing
30 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
31 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
33 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
34 to the end of the strings whereas this didn't. This would cause problems
35 if strings read with d2i_ASN1_bytes() were later modified.
36 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
38 *) Fix for base64 decode bug. When a base64 bio reads only one line of
39 data and it contains EOF it will end up returning an error. This is
40 caused by input 46 bytes long. The cause is due to the way base64
41 BIOs find the start of base64 encoded data. They do this by trying a
42 trial decode on each line until they find one that works. When they
43 do a flag is set and it starts again knowing it can pass all the
44 data directly through the decoder. Unfortunately it doesn't reset
45 the context it uses. This means that if EOF is reached an attempt
46 is made to pass two EOFs through the context and this causes the
47 resulting error. This can also cause other problems as well. As is
48 usual with these problems it takes *ages* to find and the fix is
49 trivial: move one line.
50 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
52 *) Ugly workaround to get s_client and s_server working under Windows. The
53 old code wouldn't work because it needed to select() on sockets and the
54 tty (for keypresses and to see if data could be written). Win32 only
55 supports select() on sockets so we select() with a 1s timeout on the
56 sockets and then see if any characters are waiting to be read, if none
57 are present then we retry, we also assume we can always write data to
58 the tty. This isn't nice because the code then blocks until we've
59 received a complete line of data and it is effectively polling the
60 keyboard at 1s intervals: however it's quite a bit better than not
61 working at all :-) A dedicated Windows application might handle this
62 with an event loop for example.
65 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
66 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
67 will be called when RSA_sign() and RSA_verify() are used. This is useful
68 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
69 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
70 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
71 This necessitated the support of an extra signature type NID_md5_sha1
72 for SSL signatures and modifications to the SSL library to use it instead
73 of calling RSA_public_decrypt() and RSA_private_encrypt().
76 *) Add new -verify -CAfile and -CApath options to the crl program, these
77 will lookup a CRL issuers certificate and verify the signature in a
78 similar way to the verify program. Tidy up the crl program so it
79 no longer acesses structures directly. Make the ASN1 CRL parsing a bit
80 less strict. It will now permit CRL extensions even if it is not
81 a V2 CRL: this will allow it to tolerate some broken CRLs.
84 *) Initialize all non-automatic variables each time one of the openssl
85 sub-programs is started (this is necessary as they may be started
86 multiple times from the "OpenSSL>" prompt).
87 [Lennart Bang, Bodo Moeller]
89 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
90 removing all other RSA functionality (this is what NO_RSA does). This
91 is so (for example) those in the US can disable those operations covered
92 by the RSA patent while allowing storage and parsing of RSA keys and RSA
96 *) Non-copying interface to BIO pairs.
97 (still largely untested)
100 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
101 ASCII string. This was handled independently in various places before.
104 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
105 UTF8 strings a character at a time.
108 *) Use client_version from client hello to select the protocol
109 (s23_srvr.c) and for RSA client key exchange verification
110 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
113 *) Add various utility functions to handle SPKACs, these were previously
114 handled by poking round in the structure internals. Added new function
115 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
116 print, verify and generate SPKACs. Based on an original idea from
117 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
120 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
123 *) Allow the config file extension section to be overwritten on the
124 command line. Based on an original idea from Massimiliano Pala
125 <madwolf@comune.modena.it>. The new option is called -extensions
126 and can be applied to ca, req and x509. Also -reqexts to override
127 the request extensions in req and -crlexts to override the crl extensions
131 *) Add new feature to the SPKAC handling in ca. Now you can include
132 the same field multiple times by preceding it by "XXXX." for example:
135 this is the same syntax as used in the req config file.
138 *) Allow certificate extensions to be added to certificate requests. These
139 are specified in a 'req_extensions' option of the req section of the
140 config file. They can be printed out with the -text option to req but
141 are otherwise ignored at present.
144 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
145 data read consists of only the final block it would not decrypted because
146 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
147 A misplaced 'break' also meant the decrypted final block might not be
148 copied until the next read.
151 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
152 a few extra parameters to the DH structure: these will be useful if
153 for example we want the value of 'q' or implement X9.42 DH.
156 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
157 provides hooks that allow the default DSA functions or functions on a
158 "per key" basis to be replaced. This allows hardware acceleration and
159 hardware key storage to be handled without major modification to the
160 library. Also added low level modexp hooks and CRYPTO_EX structure and
161 associated functions.
164 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
165 as "read only": it can't be written to and the buffer it points to will
166 not be freed. Reading from a read only BIO is much more efficient than
167 a normal memory BIO. This was added because there are several times when
168 an area of memory needs to be read from a BIO. The previous method was
169 to create a memory BIO and write the data to it, this results in two
170 copies of the data and an O(n^2) reading algorithm. There is a new
171 function BIO_new_mem_buf() which creates a read only memory BIO from
172 an area of memory. Also modified the PKCS#7 routines to use read only
176 *) Bugfix: ssl23_get_client_hello did not work properly when called in
177 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
178 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
179 but a retry condition occured while trying to read the rest.
182 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
183 NID_pkcs7_encrypted by default: this was wrong since this should almost
184 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
185 the encrypted data type: this is a more sensible place to put it and it
186 allows the PKCS#12 code to be tidied up that duplicated this
190 *) Changed obj_dat.pl script so it takes its input and output files on
191 the command line. This should avoid shell escape redirection problems
195 *) Initial support for certificate extension requests, these are included
196 in things like Xenroll certificate requests. Included functions to allow
197 extensions to be obtained and added.
200 *) -crlf option to s_client and s_server for sending newlines as
201 CRLF (as required by many protocols).
204 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
206 *) Install libRSAglue.a when OpenSSL is built with RSAref.
207 [Ralf S. Engelschall]
209 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
210 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
212 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
216 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
217 DH parameters/keys (q is lost during that conversion, but the resulting
218 DH parameters contain its length).
220 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
221 much faster than DH_generate_parameters (which creates parameters
222 where p = 2*q + 1), and also the smaller q makes DH computations
223 much more efficient (160-bit exponentiation instead of 1024-bit
224 exponentiation); so this provides a convenient way to support DHE
225 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
226 utter importance to use
227 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
229 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
230 when such DH parameters are used, because otherwise small subgroup
231 attacks may become possible!
234 *) Avoid memory leak in i2d_DHparams.
237 *) Allow the -k option to be used more than once in the enc program:
238 this allows the same encrypted message to be read by multiple recipients.
241 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
242 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
243 it will always use the numerical form of the OID, even if it has a short
247 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
248 method only got called if p,q,dmp1,dmq1,iqmp components were present,
249 otherwise bn_mod_exp was called. In the case of hardware keys for example
250 no private key components need be present and it might store extra data
251 in the RSA structure, which cannot be accessed from bn_mod_exp.
252 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
253 private key operations.
256 *) Added support for SPARC Linux.
259 *) pem_password_cb function type incompatibly changed from
260 typedef int pem_password_cb(char *buf, int size, int rwflag);
262 ....(char *buf, int size, int rwflag, void *userdata);
263 so that applications can pass data to their callbacks:
264 The PEM[_ASN1]_{read,write}... functions and macros now take an
265 additional void * argument, which is just handed through whenever
266 the password callback is called.
267 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
269 New function SSL_CTX_set_default_passwd_cb_userdata.
271 Compatibility note: As many C implementations push function arguments
272 onto the stack in reverse order, the new library version is likely to
273 interoperate with programs that have been compiled with the old
274 pem_password_cb definition (PEM_whatever takes some data that
275 happens to be on the stack as its last argument, and the callback
276 just ignores this garbage); but there is no guarantee whatsoever that
279 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
280 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
281 problems not only on Windows, but also on some Unix platforms.
282 To avoid problematic command lines, these definitions are now in an
283 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
284 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
287 *) MIPS III/IV assembler module is reimplemented.
290 *) More DES library cleanups: remove references to srand/rand and
291 delete an unused file.
294 *) Add support for the the free Netwide assembler (NASM) under Win32,
295 since not many people have MASM (ml) and it can be hard to obtain.
296 This is currently experimental but it seems to work OK and pass all
297 the tests. Check out INSTALL.W32 for info.
300 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
301 without temporary keys kept an extra copy of the server key,
302 and connections with temporary keys did not free everything in case
306 *) New function RSA_check_key and new openssl rsa option -check
307 for verifying the consistency of RSA keys.
308 [Ulf Moeller, Bodo Moeller]
310 *) Various changes to make Win32 compile work:
311 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
312 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
313 comparison" warnings.
314 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
317 *) Add a debugging option to PKCS#5 v2 key generation function: when
318 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
319 derived keys are printed to stderr.
322 *) Copy the flags in ASN1_STRING_dup().
323 [Roman E. Pavlov <pre@mo.msk.ru>]
325 *) The x509 application mishandled signing requests containing DSA
326 keys when the signing key was also DSA and the parameters didn't match.
328 It was supposed to omit the parameters when they matched the signing key:
329 the verifying software was then supposed to automatically use the CA's
330 parameters if they were absent from the end user certificate.
332 Omitting parameters is no longer recommended. The test was also
333 the wrong way round! This was probably due to unusual behaviour in
334 EVP_cmp_parameters() which returns 1 if the parameters match.
335 This meant that parameters were omitted when they *didn't* match and
336 the certificate was useless. Certificates signed with 'ca' didn't have
338 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
340 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
341 The interface is as follows:
343 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
344 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
345 "off" is now the default.
346 The library internally uses
347 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
348 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
349 to disable memory-checking temporarily.
351 Some inconsistent states that previously were possible (and were
352 even the default) are now avoided.
354 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
355 with each memory chunk allocated; this is occasionally more helpful
356 than just having a counter.
358 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
360 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
364 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
365 which largely parallels "options", but is for changing API behaviour,
366 whereas "options" are about protocol behaviour.
367 Initial "mode" flags are:
369 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
370 a single record has been written.
371 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
372 retries use the same buffer location.
373 (But all of the contents must be
377 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
380 *) Fix problems with no-hmac etc.
381 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
383 *) New functions RSA_get_default_method(), RSA_set_method() and
384 RSA_get_method(). These allows replacement of RSA_METHODs without having
385 to mess around with the internals of an RSA structure.
388 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
389 Also really enable memory leak checks in openssl.c and in some
391 [Chad C. Mulligan, Bodo Moeller]
393 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
394 up the length of negative integers. This has now been simplified to just
395 store the length when it is first determined and use it later, rather
396 than trying to keep track of where data is copied and updating it to
398 [Steve Henson, reported by Brien Wheeler
399 <bwheeler@authentica-security.com>]
401 *) Add a new function PKCS7_signatureVerify. This allows the verification
402 of a PKCS#7 signature but with the signing certificate passed to the
403 function itself. This contrasts with PKCS7_dataVerify which assumes the
404 certificate is present in the PKCS#7 structure. This isn't always the
405 case: certificates can be omitted from a PKCS#7 structure and be
406 distributed by "out of band" means (such as a certificate database).
409 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
410 function prototypes in pem.h, also change util/mkdef.pl to add the
411 necessary function names.
414 *) mk1mf.pl (used by Windows builds) did not properly read the
415 options set by Configure in the top level Makefile, and Configure
416 was not even able to write more than one option correctly.
417 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
420 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
421 file to be loaded from a BIO or FILE pointer. The BIO version will
422 for example allow memory BIOs to contain config info.
425 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
426 Whoever hopes to achieve shared-library compatibility across versions
427 must use this, not the compile-time macro.
428 (Exercise 0.9.4: Which is the minimum library version required by
430 Note: All this applies only to multi-threaded programs, others don't
434 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
435 through a BIO pair triggered the default case, i.e.
436 SSLerr(...,SSL_R_UNKNOWN_STATE).
439 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
440 can use the SSL library even if none of the specific BIOs is
444 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
445 for the encoded length.
446 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
448 *) Add initial documentation of the X509V3 functions.
451 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
452 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
453 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
454 secure PKCS#8 private key format with a high iteration count.
457 *) Fix determination of Perl interpreter: A perl or perl5
458 _directory_ in $PATH was also accepted as the interpreter.
459 [Ralf S. Engelschall]
461 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
462 wrong with it but it was very old and did things like calling
463 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
467 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
468 to use the new extension code.
471 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
472 with macros. This should make it easier to change their form, add extra
473 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
477 *) Add to configuration table a new entry that can specify an alternative
478 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
479 according to Mark Crispin <MRC@Panda.COM>.
483 *) DES CBC did not update the IV. Weird.
486 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
487 Changing the behaviour of the former might break existing programs --
488 where IV updating is needed, des_ncbc_encrypt can be used.
491 *) When bntest is run from "make test" it drives bc to check its
492 calculations, as well as internally checking them. If an internal check
493 fails, it needs to cause bc to give a non-zero result or make test carries
494 on without noticing the failure. Fixed.
497 *) DES library cleanups.
500 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
501 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
502 ciphers. NOTE: although the key derivation function has been verified
503 against some published test vectors it has not been extensively tested
504 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
508 *) Instead of "mkdir -p", which is not fully portable, use new
509 Perl script "util/mkdir-p.pl".
512 *) Rewrite the way password based encryption (PBE) is handled. It used to
513 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
514 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
515 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
516 the 'parameter' field of the AlgorithmIdentifier is passed to the
517 underlying key generation function so it must do its own ASN1 parsing.
518 This has also changed the EVP_PBE_CipherInit() function which now has a
519 'parameter' argument instead of literal salt and iteration count values
520 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
523 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
524 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
525 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
526 KEY" because this clashed with PKCS#8 unencrypted string. Since this
527 value was just used as a "magic string" and not used directly its
528 value doesn't matter.
531 *) Introduce some semblance of const correctness to BN. Shame C doesn't
535 *) "linux-sparc64" configuration (ultrapenguin).
536 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
537 "linux-sparc" configuration.
538 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
540 *) config now generates no-xxx options for missing ciphers.
543 *) Support the EBCDIC character set (work in progress).
544 File ebcdic.c not yet included because it has a different license.
545 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
547 *) Support BS2000/OSD-POSIX.
548 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
550 *) Make callbacks for key generation use void * instead of char *.
553 *) Make S/MIME samples compile (not yet tested).
556 *) Additional typesafe stacks.
559 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
563 Changes between 0.9.3 and 0.9.3a [29 May 1999]
565 *) New configuration variant "sco5-gcc".
567 *) Updated some demos.
568 [Sean O Riordain, Wade Scholine]
570 *) Add missing BIO_free at exit of pkcs12 application.
573 *) Fix memory leak in conf.c.
576 *) Updates for Win32 to assembler version of MD5.
579 *) Set #! path to perl in apps/der_chop to where we found it
580 instead of using a fixed path.
583 *) SHA library changes for irix64-mips4-cc.
586 *) Improvements for VMS support.
590 Changes between 0.9.2b and 0.9.3 [24 May 1999]
592 *) Bignum library bug fix. IRIX 6 passes "make test" now!
593 This also avoids the problems with SC4.2 and unpatched SC5.
594 [Andy Polyakov <appro@fy.chalmers.se>]
596 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
597 These are required because of the typesafe stack would otherwise break
598 existing code. If old code used a structure member which used to be STACK
599 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
600 sk_num or sk_value it would produce an error because the num, data members
601 are not present in STACK_OF. Now it just produces a warning. sk_set
602 replaces the old method of assigning a value to sk_value
603 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
604 that does this will no longer work (and should use sk_set instead) but
605 this could be regarded as a "questionable" behaviour anyway.
608 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
609 correctly handle encrypted S/MIME data.
612 *) Change type of various DES function arguments from des_cblock
613 (which means, in function argument declarations, pointer to char)
614 to des_cblock * (meaning pointer to array with 8 char elements),
615 which allows the compiler to do more typechecking; it was like
616 that back in SSLeay, but with lots of ugly casts.
618 Introduce new type const_des_cblock.
621 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
622 problems: find RecipientInfo structure that matches recipient certificate
623 and initialise the ASN1 structures properly based on passed cipher.
626 *) Belatedly make the BN tests actually check the results.
629 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
630 to and from BNs: it was completely broken. New compilation option
631 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
632 key elements as negative integers.
635 *) Reorganize and speed up MD5.
636 [Andy Polyakov <appro@fy.chalmers.se>]
639 [Richard Levitte <richard@levitte.org>]
641 *) New option -out to asn1parse to allow the parsed structure to be
642 output to a file. This is most useful when combined with the -strparse
643 option to examine the output of things like OCTET STRINGS.
646 *) Make SSL library a little more fool-proof by not requiring any longer
647 that SSL_set_{accept,connect}_state be called before
648 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
649 in many applications because usually everything *appeared* to work as
650 intended anyway -- now it really works as intended).
653 *) Move openssl.cnf out of lib/.
656 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
657 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
658 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
659 [Ralf S. Engelschall]
661 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
662 handle PKCS#7 enveloped data properly.
663 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
665 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
666 copying pointers. The cert_st handling is changed by this in
667 various ways (and thus what used to be known as ctx->default_cert
668 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
669 any longer when s->cert does not give us what we need).
670 ssl_cert_instantiate becomes obsolete by this change.
671 As soon as we've got the new code right (possibly it already is?),
672 we have solved a couple of bugs of the earlier code where s->cert
673 was used as if it could not have been shared with other SSL structures.
675 Note that using the SSL API in certain dirty ways now will result
676 in different behaviour than observed with earlier library versions:
677 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
678 does not influence s as it used to.
680 In order to clean up things more thoroughly, inside SSL_SESSION
681 we don't use CERT any longer, but a new structure SESS_CERT
682 that holds per-session data (if available); currently, this is
683 the peer's certificate chain and, for clients, the server's certificate
684 and temporary key. CERT holds only those values that can have
685 meaningful defaults in an SSL_CTX.
688 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
689 from the internal representation. Various PKCS#7 fixes: remove some
690 evil casts and set the enc_dig_alg field properly based on the signing
694 *) Allow PKCS#12 password to be set from the command line or the
695 environment. Let 'ca' get its config file name from the environment
696 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
700 *) Allow certificate policies extension to use an IA5STRING for the
701 organization field. This is contrary to the PKIX definition but
702 VeriSign uses it and IE5 only recognises this form. Document 'x509'
706 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
707 without disallowing inline assembler and the like for non-pedantic builds.
710 *) Support Borland C++ builder.
711 [Janez Jere <jj@void.si>, modified by Ulf Möller]
716 *) SHA-1 cleanups and performance enhancements.
717 [Andy Polyakov <appro@fy.chalmers.se>]
719 *) Sparc v8plus assembler for the bignum library.
720 [Andy Polyakov <appro@fy.chalmers.se>]
722 *) Accept any -xxx and +xxx compiler options in Configure.
725 *) Update HPUX configuration.
728 *) Add missing sk_<type>_unshift() function to safestack.h
729 [Ralf S. Engelschall]
731 *) New function SSL_CTX_use_certificate_chain_file that sets the
732 "extra_cert"s in addition to the certificate. (This makes sense
733 only for "PEM" format files, as chains as a whole are not
737 *) Support verify_depth from the SSL API.
738 x509_vfy.c had what can be considered an off-by-one-error:
739 Its depth (which was not part of the external interface)
740 was actually counting the number of certificates in a chain;
741 now it really counts the depth.
744 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
745 instead of X509err, which often resulted in confusing error
746 messages since the error codes are not globally unique
747 (e.g. an alleged error in ssl3_accept when a certificate
748 didn't match the private key).
750 *) New function SSL_CTX_set_session_id_context that allows to set a default
751 value (so that you don't need SSL_set_session_id_context for each
752 connection using the SSL_CTX).
755 *) OAEP decoding bug fix.
758 *) Support INSTALL_PREFIX for package builders, as proposed by
762 *) New Configure options "threads" and "no-threads". For systems
763 where the proper compiler options are known (currently Solaris
764 and Linux), "threads" is the default.
767 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
770 *) Install various scripts to $(OPENSSLDIR)/misc, not to
771 $(INSTALLTOP)/bin -- they shouldn't clutter directories
772 such as /usr/local/bin.
775 *) "make linux-shared" to build shared libraries.
776 [Niels Poppe <niels@netbox.org>]
778 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
781 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
782 extension adding in x509 utility.
785 *) Remove NOPROTO sections and error code comments.
788 *) Partial rewrite of the DEF file generator to now parse the ANSI
792 *) New Configure options --prefix=DIR and --openssldir=DIR.
795 *) Complete rewrite of the error code script(s). It is all now handled
796 by one script at the top level which handles error code gathering,
797 header rewriting and C source file generation. It should be much better
798 than the old method: it now uses a modified version of Ulf's parser to
799 read the ANSI prototypes in all header files (thus the old K&R definitions
800 aren't needed for error creation any more) and do a better job of
801 translating function codes into names. The old 'ASN1 error code imbedded
802 in a comment' is no longer necessary and it doesn't use .err files which
803 have now been deleted. Also the error code call doesn't have to appear all
804 on one line (which resulted in some large lines...).
807 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
810 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
811 0 (which usually indicates a closed connection), but continue reading.
814 *) Fix some race conditions.
817 *) Add support for CRL distribution points extension. Add Certificate
818 Policies and CRL distribution points documentation.
821 *) Move the autogenerated header file parts to crypto/opensslconf.h.
824 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
825 8 of keying material. Merlin has also confirmed interop with this fix
826 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
827 [Merlin Hughes <merlin@baltimore.ie>]
829 *) Fix lots of warnings.
830 [Richard Levitte <levitte@stacken.kth.se>]
832 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
833 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
834 [Richard Levitte <levitte@stacken.kth.se>]
836 *) Fix problems with sizeof(long) == 8.
837 [Andy Polyakov <appro@fy.chalmers.se>]
839 *) Change functions to ANSI C.
842 *) Fix typos in error codes.
843 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
845 *) Remove defunct assembler files from Configure.
848 *) SPARC v8 assembler BIGNUM implementation.
849 [Andy Polyakov <appro@fy.chalmers.se>]
851 *) Support for Certificate Policies extension: both print and set.
852 Various additions to support the r2i method this uses.
855 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
856 return a const string when you are expecting an allocated buffer.
859 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
860 types DirectoryString and DisplayText.
863 *) Add code to allow r2i extensions to access the configuration database,
864 add an LHASH database driver and add several ctx helper functions.
867 *) Fix an evil bug in bn_expand2() which caused various BN functions to
868 fail when they extended the size of a BIGNUM.
871 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
872 support typesafe stack.
875 *) Fix typo in SSL_[gs]et_options().
876 [Nils Frostberg <nils@medcom.se>]
878 *) Delete various functions and files that belonged to the (now obsolete)
879 old X509V3 handling code.
882 *) New Configure option "rsaref".
885 *) Don't auto-generate pem.h.
888 *) Introduce type-safe ASN.1 SETs.
891 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
892 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
894 *) Introduce type-safe STACKs. This will almost certainly break lots of code
895 that links with OpenSSL (well at least cause lots of warnings), but fear
896 not: the conversion is trivial, and it eliminates loads of evil casts. A
897 few STACKed things have been converted already. Feel free to convert more.
898 In the fullness of time, I'll do away with the STACK type altogether.
901 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
902 specified in <certfile> by updating the entry in the index.txt file.
903 This way one no longer has to edit the index.txt file manually for
904 revoking a certificate. The -revoke option does the gory details now.
905 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
907 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
908 `-text' option at all and this way the `-noout -text' combination was
909 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
910 [Ralf S. Engelschall]
912 *) Make sure a corresponding plain text error message exists for the
913 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
914 verify callback function determined that a certificate was revoked.
915 [Ralf S. Engelschall]
917 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
918 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
919 all available cipers including rc5, which was forgotten until now.
920 In order to let the testing shell script know which algorithms
921 are available, a new (up to now undocumented) command
922 "openssl list-cipher-commands" is used.
925 *) Bugfix: s_client occasionally would sleep in select() when
926 it should have checked SSL_pending() first.
929 *) New functions DSA_do_sign and DSA_do_verify to provide access to
930 the raw DSA values prior to ASN.1 encoding.
933 *) Tweaks to Configure
934 [Niels Poppe <niels@netbox.org>]
936 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
940 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
943 *) New config option to avoid instructions that are illegal on the 80386.
944 The default code is faster, but requires at least a 486.
947 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
948 SSL2_SERVER_VERSION (not used at all) macros, which are now the
949 same as SSL2_VERSION anyway.
952 *) New "-showcerts" option for s_client.
955 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
956 application. Various cleanups and fixes.
959 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
960 modify error routines to work internally. Add error codes and PBE init
961 to library startup routines.
964 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
965 packing functions to asn1 and evp. Changed function names and error
969 *) PKCS12 integration: and so it begins... First of several patches to
970 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
974 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
975 and display support for Thawte strong extranet extension.
978 *) Add LinuxPPC support.
979 [Jeff Dubrule <igor@pobox.org>]
981 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
982 bn_div_words in alpha.s.
983 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
985 *) Make sure the RSA OAEP test is skipped under -DRSAref because
986 OAEP isn't supported when OpenSSL is built with RSAref.
987 [Ulf Moeller <ulf@fitug.de>]
989 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
990 so they no longer are missing under -DNOPROTO.
991 [Soren S. Jorvang <soren@t.dk>]
994 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
996 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
997 doesn't work when the session is reused. Coming soon!
1000 *) Fix a security hole, that allows sessions to be reused in the wrong
1001 context thus bypassing client cert protection! All software that uses
1002 client certs and session caches in multiple contexts NEEDS PATCHING to
1003 allow session reuse! A fuller solution is in the works.
1004 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
1006 *) Some more source tree cleanups (removed obsolete files
1007 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
1008 permission on "config" script to be executable) and a fix for the INSTALL
1010 [Ulf Moeller <ulf@fitug.de>]
1012 *) Remove some legacy and erroneous uses of malloc, free instead of
1014 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
1016 *) Make rsa_oaep_test return non-zero on error.
1017 [Ulf Moeller <ulf@fitug.de>]
1019 *) Add support for native Solaris shared libraries. Configure
1020 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
1021 if someone would make that last step automatic.
1022 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
1024 *) ctx_size was not built with the right compiler during "make links". Fixed.
1027 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
1028 except NULL ciphers". This means the default cipher list will no longer
1029 enable NULL ciphers. They need to be specifically enabled e.g. with
1030 the string "DEFAULT:eNULL".
1033 *) Fix to RSA private encryption routines: if p < q then it would
1034 occasionally produce an invalid result. This will only happen with
1035 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
1038 *) Be less restrictive and allow also `perl util/perlpath.pl
1039 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
1040 because this way one can also use an interpreter named `perl5' (which is
1041 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
1042 installed as `perl').
1043 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1045 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
1046 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1048 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
1049 advapi32.lib to Win32 build and change the pem test comparision
1050 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
1051 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
1052 and crypto/des/ede_cbcm_enc.c.
1055 *) DES quad checksum was broken on big-endian architectures. Fixed.
1058 *) Comment out two functions in bio.h that aren't implemented. Fix up the
1059 Win32 test batch file so it (might) work again. The Win32 test batch file
1060 is horrible: I feel ill....
1063 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
1064 in e_os.h. Audit of header files to check ANSI and non ANSI
1065 sections: 10 functions were absent from non ANSI section and not exported
1066 from Windows DLLs. Fixed up libeay.num for new functions.
1069 *) Make `openssl version' output lines consistent.
1070 [Ralf S. Engelschall]
1072 *) Fix Win32 symbol export lists for BIO functions: Added
1073 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
1074 to ms/libeay{16,32}.def.
1075 [Ralf S. Engelschall]
1077 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
1078 fine under Unix and passes some trivial tests I've now added. But the
1079 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
1080 added to make sure no one expects that this stuff really works in the
1081 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
1082 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
1084 [Ralf S. Engelschall]
1086 *) Fix the generation of two part addresses in perl.
1087 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
1089 *) Add config entry for Linux on MIPS.
1090 [John Tobey <jtobey@channel1.com>]
1092 *) Make links whenever Configure is run, unless we are on Windoze.
1095 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
1096 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
1100 *) Add a useful kludge to allow package maintainers to specify compiler and
1101 other platforms details on the command line without having to patch the
1102 Configure script everytime: One now can use ``perl Configure
1103 <id>:<details>'', i.e. platform ids are allowed to have details appended
1104 to them (seperated by colons). This is treated as there would be a static
1105 pre-configured entry in Configure's %table under key <id> with value
1106 <details> and ``perl Configure <id>'' is called. So, when you want to
1107 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
1108 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
1109 now, which overrides the FreeBSD-elf entry on-the-fly.
1110 [Ralf S. Engelschall]
1112 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
1115 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
1116 on the `perl Configure ...' command line. This way one can compile
1117 OpenSSL libraries with Position Independent Code (PIC) which is needed
1118 for linking it into DSOs.
1119 [Ralf S. Engelschall]
1121 *) Remarkably, export ciphers were totally broken and no-one had noticed!
1125 *) Cleaned up the LICENSE document: The official contact for any license
1126 questions now is the OpenSSL core team under openssl-core@openssl.org.
1127 And add a paragraph about the dual-license situation to make sure people
1128 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
1129 to the OpenSSL toolkit.
1130 [Ralf S. Engelschall]
1132 *) General source tree makefile cleanups: Made `making xxx in yyy...'
1133 display consistent in the source tree and replaced `/bin/rm' by `rm'.
1134 Additonally cleaned up the `make links' target: Remove unnecessary
1135 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
1136 to speed processing and no longer clutter the display with confusing
1137 stuff. Instead only the actually done links are displayed.
1138 [Ralf S. Engelschall]
1140 *) Permit null encryption ciphersuites, used for authentication only. It used
1141 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
1142 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
1146 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
1147 signed attributes when verifying signatures (this would break them),
1148 the detached data encoding was wrong and public keys obtained using
1149 X509_get_pubkey() weren't freed.
1152 *) Add text documentation for the BUFFER functions. Also added a work around
1153 to a Win95 console bug. This was triggered by the password read stuff: the
1154 last character typed gets carried over to the next fread(). If you were
1155 generating a new cert request using 'req' for example then the last
1156 character of the passphrase would be CR which would then enter the first
1160 *) Added the new `Includes OpenSSL Cryptography Software' button as
1161 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
1162 button and can be used by applications based on OpenSSL to show the
1163 relationship to the OpenSSL project.
1164 [Ralf S. Engelschall]
1166 *) Remove confusing variables in function signatures in files
1167 ssl/ssl_lib.c and ssl/ssl.h.
1168 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1170 *) Don't install bss_file.c under PREFIX/include/
1171 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1173 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
1174 functions that return function pointers and has support for NT specific
1175 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1176 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1177 unsigned to signed types: this was killing the Win32 compile.
1180 *) Add new certificate file to stack functions,
1181 SSL_add_dir_cert_subjects_to_stack() and
1182 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1183 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1184 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1185 This means that Apache-SSL and similar packages don't have to mess around
1186 to add as many CAs as they want to the preferred list.
1189 *) Experiment with doxygen documentation. Currently only partially applied to
1191 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1192 openssl.doxy as the configuration file.
1195 *) Get rid of remaining C++-style comments which strict C compilers hate.
1196 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1198 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1199 compiled in by default: it has problems with large keys.
1202 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1203 DH private keys and/or callback functions which directly correspond to
1204 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1205 is needed for applications which have to configure certificates on a
1206 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1208 For the RSA certificate situation is makes no difference, but
1209 for the DSA certificate situation this fixes the "no shared cipher"
1210 problem where the OpenSSL cipher selection procedure failed because the
1211 temporary keys were not overtaken from the context and the API provided
1212 no way to reconfigure them.
1213 The new functions now let applications reconfigure the stuff and they
1214 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1215 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1216 non-public-API function ssl_cert_instantiate() is used as a helper
1217 function and also to reduce code redundancy inside ssl_rsa.c.
1218 [Ralf S. Engelschall]
1220 *) Move s_server -dcert and -dkey options out of the undocumented feature
1221 area because they are useful for the DSA situation and should be
1222 recognized by the users.
1223 [Ralf S. Engelschall]
1225 *) Fix the cipher decision scheme for export ciphers: the export bits are
1226 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1227 SSL_EXP_MASK. So, the original variable has to be used instead of the
1228 already masked variable.
1229 [Richard Levitte <levitte@stacken.kth.se>]
1231 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1232 [Richard Levitte <levitte@stacken.kth.se>]
1234 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1235 from `int' to `unsigned int' because it's a length and initialized by
1236 EVP_DigestFinal() which expects an `unsigned int *'.
1237 [Richard Levitte <levitte@stacken.kth.se>]
1239 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1240 script. Instead use the usual Shell->Perl transition trick.
1241 [Ralf S. Engelschall]
1243 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1244 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1245 -noout -modulus' as it's already the case for `openssl rsa -noout
1246 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1247 currently the public key is printed (a decision which was already done by
1248 `openssl dsa -modulus' in the past) which serves a similar purpose.
1249 Additionally the NO_RSA no longer completely removes the whole -modulus
1250 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1252 [Ralf S. Engelschall]
1254 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1255 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1256 [Arne Ansper <arne@ats.cyber.ee>]
1258 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1259 to be added. Now both 'req' and 'ca' can use new objects defined in the
1263 *) Add cool BIO that does syslog (or event log on NT).
1264 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1266 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1267 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1268 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1269 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1272 *) Add preliminary config info for new extension code.
1275 *) Make RSA_NO_PADDING really use no padding.
1276 [Ulf Moeller <ulf@fitug.de>]
1278 *) Generate errors when private/public key check is done.
1281 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1282 for some CRL extensions and new objects added.
1285 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1286 key usage extension and fuller support for authority key id.
1289 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1290 padding method for RSA, which is recommended for new applications in PKCS
1291 #1 v2.0 (RFC 2437, October 1998).
1292 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1293 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1294 against Bleichbacher's attack on RSA.
1295 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1298 *) Updates to the new SSL compression code
1299 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1301 *) Fix so that the version number in the master secret, when passed
1302 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1303 (because the server will not accept higher), that the version number
1304 is 0x03,0x01, not 0x03,0x00
1305 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1307 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1308 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1309 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1312 *) Support for RAW extensions where an arbitrary extension can be
1313 created by including its DER encoding. See apps/openssl.cnf for
1317 *) Make sure latest Perl versions don't interpret some generated C array
1318 code as Perl array code in the crypto/err/err_genc.pl script.
1319 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1321 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1322 not many people have the assembler. Various Win32 compilation fixes and
1323 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1327 *) Modify configure script 'Configure' to automatically create crypto/date.h
1328 file under Win32 and also build pem.h from pem.org. New script
1329 util/mkfiles.pl to create the MINFO file on environments that can't do a
1330 'make files': perl util/mkfiles.pl >MINFO should work.
1333 *) Major rework of DES function declarations, in the pursuit of correctness
1334 and purity. As a result, many evil casts evaporated, and some weirdness,
1335 too. You may find this causes warnings in your code. Zapping your evil
1336 casts will probably fix them. Mostly.
1339 *) Fix for a typo in asn1.h. Bug fix to object creation script
1340 obj_dat.pl. It considered a zero in an object definition to mean
1341 "end of object": none of the objects in objects.h have any zeros
1342 so it wasn't spotted.
1343 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1345 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1346 Masking (CBCM). In the absence of test vectors, the best I have been able
1347 to do is check that the decrypt undoes the encrypt, so far. Send me test
1348 vectors if you have them.
1351 *) Correct calculation of key length for export ciphers (too much space was
1352 allocated for null ciphers). This has not been tested!
1355 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1356 message is now correct (it understands "crypto" and "ssl" on its
1357 command line). There is also now an "update" option. This will update
1358 the util/ssleay.num and util/libeay.num files with any new functions.
1360 perl util/mkdef.pl crypto ssl update
1361 it will update them.
1364 *) Overhauled the Perl interface (perl/*):
1365 - ported BN stuff to OpenSSL's different BN library
1366 - made the perl/ source tree CVS-aware
1367 - renamed the package from SSLeay to OpenSSL (the files still contain
1368 their history because I've copied them in the repository)
1369 - removed obsolete files (the test scripts will be replaced
1370 by better Test::Harness variants in the future)
1371 [Ralf S. Engelschall]
1373 *) First cut for a very conservative source tree cleanup:
1374 1. merge various obsolete readme texts into doc/ssleay.txt
1375 where we collect the old documents and readme texts.
1376 2. remove the first part of files where I'm already sure that we no
1377 longer need them because of three reasons: either they are just temporary
1378 files which were left by Eric or they are preserved original files where
1379 I've verified that the diff is also available in the CVS via "cvs diff
1380 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1381 the crypto/md/ stuff).
1382 [Ralf S. Engelschall]
1384 *) More extension code. Incomplete support for subject and issuer alt
1385 name, issuer and authority key id. Change the i2v function parameters
1386 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1387 what that's for :-) Fix to ASN1 macro which messed up
1388 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1391 *) Preliminary support for ENUMERATED type. This is largely copied from the
1395 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1396 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1398 *) Make sure `make rehash' target really finds the `openssl' program.
1399 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1401 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1402 like to hear about it if this slows down other processors.
1405 *) Add CygWin32 platform information to Configure script.
1406 [Alan Batie <batie@aahz.jf.intel.com>]
1408 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1409 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1411 *) New program nseq to manipulate netscape certificate sequences
1414 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1418 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1419 but the BN code had some problems that would cause failures when
1420 doing certificate verification and some other functions.
1421 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1423 *) Add ASN1 and PEM code to support netscape certificate sequences.
1426 *) Add ASN1 and PEM code to support netscape certificate sequences.
1429 *) Add several PKIX and private extended key usage OIDs.
1432 *) Modify the 'ca' program to handle the new extension code. Modify
1433 openssl.cnf for new extension format, add comments.
1436 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1437 and add a sample to openssl.cnf so req -x509 now adds appropriate
1441 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1442 error code, add initial support to X509_print() and x509 application.
1445 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1446 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1447 stuff is currently isolated and isn't even compiled yet.
1450 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1451 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1452 Removed the versions check from X509 routines when loading extensions:
1453 this allows certain broken certificates that don't set the version
1454 properly to be processed.
1457 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1458 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1459 can still be regenerated with "make depend".
1462 *) Spelling mistake in C version of CAST-128.
1463 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1465 *) Changes to the error generation code. The perl script err-code.pl
1466 now reads in the old error codes and retains the old numbers, only
1467 adding new ones if necessary. It also only changes the .err files if new
1468 codes are added. The makefiles have been modified to only insert errors
1469 when needed (to avoid needlessly modifying header files). This is done
1470 by only inserting errors if the .err file is newer than the auto generated
1471 C file. To rebuild all the error codes from scratch (the old behaviour)
1472 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1473 or delete all the .err files.
1476 *) CAST-128 was incorrectly implemented for short keys. The C version has
1477 been fixed, but is untested. The assembler versions are also fixed, but
1478 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1479 to regenerate it if needed.
1480 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1481 Hagino <itojun@kame.net>]
1483 *) File was opened incorrectly in randfile.c.
1484 [Ulf Möller <ulf@fitug.de>]
1486 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1487 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1488 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1489 al: it's just almost always a UTCTime. Note this patch adds new error
1490 codes so do a "make errors" if there are problems.
1493 *) Correct Linux 1 recognition in config.
1494 [Ulf Möller <ulf@fitug.de>]
1496 *) Remove pointless MD5 hash when using DSA keys in ca.
1497 [Anonymous <nobody@replay.com>]
1499 *) Generate an error if given an empty string as a cert directory. Also
1500 generate an error if handed NULL (previously returned 0 to indicate an
1501 error, but didn't set one).
1502 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1504 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1507 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1508 parameters. This was causing a warning which killed off the Win32 compile.
1511 *) Remove C++ style comments from crypto/bn/bn_local.h.
1512 [Neil Costigan <neil.costigan@celocom.com>]
1514 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1515 based on a text string, looking up short and long names and finally
1516 "dot" format. The "dot" format stuff didn't work. Added new function
1517 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1518 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1519 OID is not part of the table.
1522 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1523 X509_LOOKUP_by_alias().
1526 *) Sort openssl functions by name.
1529 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1530 encryption from sample DSA keys (in case anyone is interested the password
1534 *) Make _all_ *_free functions accept a NULL pointer.
1535 [Frans Heymans <fheymans@isaserver.be>]
1537 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1539 [Anonymous <nobody@replay.com>]
1541 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1542 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1544 *) Don't blow it for numeric -newkey arguments to apps/req.
1545 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1547 *) Temp key "for export" tests were wrong in s3_srvr.c.
1548 [Anonymous <nobody@replay.com>]
1550 *) Add prototype for temp key callback functions
1551 SSL_CTX_set_tmp_{rsa,dh}_callback().
1554 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1555 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1558 *) X509_name_add_entry() freed the wrong thing after an error.
1559 [Arne Ansper <arne@ats.cyber.ee>]
1561 *) rsa_eay.c would attempt to free a NULL context.
1562 [Arne Ansper <arne@ats.cyber.ee>]
1564 *) BIO_s_socket() had a broken should_retry() on Windoze.
1565 [Arne Ansper <arne@ats.cyber.ee>]
1567 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1568 [Arne Ansper <arne@ats.cyber.ee>]
1570 *) Make sure the already existing X509_STORE->depth variable is initialized
1571 in X509_STORE_new(), but document the fact that this variable is still
1572 unused in the certificate verification process.
1573 [Ralf S. Engelschall]
1575 *) Fix the various library and apps files to free up pkeys obtained from
1576 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1579 *) Fix reference counting in X509_PUBKEY_get(). This makes
1580 demos/maurice/example2.c work, amongst others, probably.
1581 [Steve Henson and Ben Laurie]
1583 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1584 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1585 are no longer created. This way we have a single and consistent command
1586 line interface `openssl <command>', similar to `cvs <command>'.
1587 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1589 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1590 BIT STRING wrapper always have zero unused bits.
1593 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1596 *) Make the top-level INSTALL documentation easier to understand.
1599 *) Makefiles updated to exit if an error occurs in a sub-directory
1600 make (including if user presses ^C) [Paul Sutton]
1602 *) Make Montgomery context stuff explicit in RSA data structure.
1605 *) Fix build order of pem and err to allow for generated pem.h.
1608 *) Fix renumbering bug in X509_NAME_delete_entry().
1611 *) Enhanced the err-ins.pl script so it makes the error library number
1612 global and can add a library name. This is needed for external ASN1 and
1613 other error libraries.
1616 *) Fixed sk_insert which never worked properly.
1619 *) Fix ASN1 macros so they can handle indefinite length construted
1620 EXPLICIT tags. Some non standard certificates use these: they can now
1624 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1625 into a single doc/ssleay.txt bundle. This way the information is still
1626 preserved but no longer messes up this directory. Now it's new room for
1627 the new set of documenation files.
1628 [Ralf S. Engelschall]
1630 *) SETs were incorrectly DER encoded. This was a major pain, because they
1631 shared code with SEQUENCEs, which aren't coded the same. This means that
1632 almost everything to do with SETs or SEQUENCEs has either changed name or
1633 number of arguments.
1634 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1636 *) Fix test data to work with the above.
1639 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1640 was already fixed by Eric for 0.9.1 it seems.
1641 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1643 *) Autodetect FreeBSD3.
1646 *) Fix various bugs in Configure. This affects the following platforms:
1650 unixware-2.0-pentium
1654 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1655 before they are needed.
1658 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1662 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1664 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1665 changed SSLeay to OpenSSL in version strings.
1666 [Ralf S. Engelschall]
1668 *) Some fixups to the top-level documents.
1671 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1672 because the symlink to include/ was missing.
1673 [Ralf S. Engelschall]
1675 *) Incorporated the popular no-RSA/DSA-only patches
1676 which allow to compile a RSA-free SSLeay.
1677 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1679 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1680 when "ssleay" is still not found.
1681 [Ralf S. Engelschall]
1683 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1684 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1686 *) Updated the README file.
1687 [Ralf S. Engelschall]
1689 *) Added various .cvsignore files in the CVS repository subdirs
1690 to make a "cvs update" really silent.
1691 [Ralf S. Engelschall]
1693 *) Recompiled the error-definition header files and added
1694 missing symbols to the Win32 linker tables.
1695 [Ralf S. Engelschall]
1697 *) Cleaned up the top-level documents;
1698 o new files: CHANGES and LICENSE
1699 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1700 o merged COPYRIGHT into LICENSE
1701 o removed obsolete TODO file
1702 o renamed MICROSOFT to INSTALL.W32
1703 [Ralf S. Engelschall]
1705 *) Removed dummy files from the 0.9.1b source tree:
1706 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1707 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1710 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1711 [Ralf S. Engelschall]
1713 *) Added various platform portability fixes.
1716 *) The Genesis of the OpenSSL rpject:
1717 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1718 Young and Tim J. Hudson created while they were working for C2Net until
1720 [The OpenSSL Project]
1723 Changes between 0.9.0b and 0.9.1b [not released]
1725 *) Updated a few CA certificates under certs/
1728 *) Changed some BIGNUM api stuff.
1731 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1732 DGUX x86, Linux Alpha, etc.
1735 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1736 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1740 *) Add -strparse option to asn1pars program which parses nested
1742 [Dr Stephen Henson <shenson@bigfoot.com>]
1744 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1747 *) DSA fix for "ca" program.
1750 *) Added "-genkey" option to "dsaparam" program.
1753 *) Added RIPE MD160 (rmd160) message digest.
1756 *) Added -a (all) option to "ssleay version" command.
1759 *) Added PLATFORM define which is the id given to Configure.
1762 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1765 *) Extended the ASN.1 parser routines.
1768 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1771 *) Added a BN_CTX to the BN library.
1774 *) Fixed the weak key values in DES library
1777 *) Changed API in EVP library for cipher aliases.
1780 *) Added support for RC2/64bit cipher.
1783 *) Converted the lhash library to the crypto/mem.c functions.
1786 *) Added more recognized ASN.1 object ids.
1789 *) Added more RSA padding checks for SSL/TLS.
1792 *) Added BIO proxy/filter functionality.
1795 *) Added extra_certs to SSL_CTX which can be used
1796 send extra CA certificates to the client in the CA cert chain sending
1797 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1800 *) Now Fortezza is denied in the authentication phase because
1801 this is key exchange mechanism is not supported by SSLeay at all.
1804 *) Additional PKCS1 checks.
1807 *) Support the string "TLSv1" for all TLS v1 ciphers.
1810 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1811 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1814 *) Fixed a few memory leaks.
1817 *) Fixed various code and comment typos.
1820 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1821 bytes sent in the client random.
