5 Changes between 0.9.5 and 0.9.5a [XX XXX 2000]
6
7 *) For easily testing in shell scripts whether some command
8 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
9 returns with exit code 0 iff no command of the given name is available.
10 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
11 the output goes to stdout and nothing is printed to stderr.
12 Additional arguments are always ignored.
13
14 Since for each cipher there is a command of the same name,
15 the 'no-cipher' compilation switches can be tested this way.
16
17 ('openssl no-XXX' is not able to detect pseudo-commands such
18 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
19 [Bodo Moeller]
20
21 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
22 [Bodo Moeller]
23
24 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
25 is set; it will be thrown away anyway because each handshake creates
26 its own key.
27 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
28 to parameters -- in previous versions (since OpenSSL 0.9.3) the
29 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
30 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
31 [Bodo Moeller]
32
33 *) New s_client option -ign_eof: EOF at stdin is ignored, and
34 'Q' and 'R' lose their special meanings (quit/renegotiate).
35 This is part of what -quiet does; unlike -quiet, -ign_eof
36 does not suppress any output.
37 [Richard Levitte]
38
39 *) Add compatibility options to the purpose and trust code. The
40 purpose X509_PURPOSE_ANY is "any purpose" which automatically
41 accepts a certificate or CA, this was the previous behaviour,
42 with all the associated security issues.
43
44 X509_TRUST_COMPAT is the old trust behaviour: only and
45 automatically trust self signed roots in certificate store. A
46 new trust setting X509_TRUST_DEFAULT is used to specify that
47 a purpose has no associated trust setting and it should instead
48 use the value in the default purpose.
49 [Steve Henson]
50
51 *) Fix the PKCS#8 DSA private key code so it decodes keys again
52 and fix a memory leak.
53 [Steve Henson]
54
55 *) In util/mkerr.pl (which implements 'make errors'), preserve
56 reason strings from the previous version of the .c file, as
57 the default to have only downcase letters (and digits) in
58 automatically generated reasons codes is not always appropriate.
59 [Bodo Moeller]
60
61 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
62 using strerror. Previously, ERR_reason_error_string() returned
63 library names as reason strings for SYSerr; but SYSerr is a special
64 case where small numbers are errno values, not library numbers.
65 [Bodo Moeller]
66
67 *) Add '-dsaparam' option to 'openssl dhparam' application. This
68 converts DSA parameters into DH parameters. (When creating parameters,
69 DSA_generate_parameters is used.)
70 [Bodo Moeller]
71
72 *) Include 'length' (recommended exponent length) in C code generated
73 by 'openssl dhparam -C'.
74 [Bodo Moeller]
75
76 *) The second argument to set_label in perlasm was already being used
77 so couldn't be used as a "file scope" flag. Moved to third argument
78 which was free.
79 [Steve Henson]
80
81 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
82 instead of RAND_bytes for encryption IVs and salts.
83 [Bodo Moeller]
84
85 *) Include RAND_status() into RAND_METHOD instead of implementing
86 it only for md_rand.c Otherwise replacing the PRNG by calling
87 RAND_set_rand_method would be impossible.
88 [Bodo Moeller]
89
90 *) Don't let DSA_generate_key() enter an infinite loop if the random
91 number generation fails.
92 [Bodo Moeller]
93
94 *) New 'rand' application for creating pseudo-random output.
95 [Bodo Moeller]
96
97 *) Added configuration support for Linux/IA64
98 [Rolf Haberrecker <rolf@suse.de>]
99
100 *) Assembler module support for Mingw32.
101 [Ulf Möller]
102
103 *) Shared library support for HPUX (in shlib/).
104 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
105
106 *) Shared library support for Solaris gcc.
107 [Lutz Behnke <behnke@trustcenter.de>]
108
109 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
110
111 *) PKCS7_encrypt() was adding text MIME headers twice because they
112 were added manually and by SMIME_crlf_copy().
113 [Steve Henson]
114
115 *) In bntest.c don't call BN_rand with zero bits argument.
116 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
117
118 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
119 case was implemented. This caused BN_div_recp() to fail occasionally.
120 [Ulf Möller]
121
122 *) Add an optional second argument to the set_label() in the perl
123 assembly language builder. If this argument exists and is set
124 to 1 it signals that the assembler should use a symbol whose
125 scope is the entire file, not just the current function. This
126 is needed with MASM which uses the format label:: for this scope.
127 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
128
129 *) Change the ASN1 types so they are typedefs by default. Before
130 almost all types were #define'd to ASN1_STRING which was causing
131 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
132 for example.
133 [Steve Henson]
134
135 *) Change names of new functions to the new get1/get0 naming
136 convention: After 'get1', the caller owns a reference count
137 and has to call ..._free; 'get0' returns a pointer to some
138 data structure without incrementing reference counters.
139 (Some of the existing 'get' functions increment a reference
140 counter, some don't.)
141 Similarly, 'set1' and 'add1' functions increase reference
142 counters or duplicate objects.
143 [Steve Henson]
144
145 *) Allow for the possibility of temp RSA key generation failure:
146 the code used to assume it always worked and crashed on failure.
147 [Steve Henson]
148
149 *) Fix potential buffer overrun problem in BIO_printf().
150 [Ulf Möller, using public domain code by Patrick Powell; problem
151 pointed out by David Sacerdote <das33@cornell.edu>]
152
153 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
154 RAND_egd() and RAND_status(). In the command line application,
155 the EGD socket can be specified like a seed file using RANDFILE
156 or -rand.
157 [Ulf Möller]
158
159 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
160 Some CAs (e.g. Verisign) distribute certificates in this form.
161 [Steve Henson]
162
163 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
164 list to exclude them. This means that no special compilation option
165 is needed to use anonymous DH: it just needs to be included in the
166 cipher list.
167 [Steve Henson]
168
169 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
170 EVP_MD_type. The old functionality is available in a new macro called
171 EVP_MD_md(). Change code that uses it and update docs.
172 [Steve Henson]
173
174 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
175 where the 'void *' argument is replaced by a function pointer argument.
176 Previously 'void *' was abused to point to functions, which works on
177 many platforms, but is not correct. As these functions are usually
178 called by macros defined in OpenSSL header files, most source code
179 should work without changes.
180 [Richard Levitte]
181
182 *) <openssl/opensslconf.h> (which is created by Configure) now contains
183 sections with information on -D... compiler switches used for
184 compiling the library so that applications can see them. To enable
185 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
186 must be defined. E.g.,
187 #define OPENSSL_ALGORITHM_DEFINES
188 #include <openssl/opensslconf.h>
189 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
190 [Richard Levitte, Ulf and Bodo Möller]
191
192 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
193 record layer.
194 [Bodo Moeller]
195
196 *) Change the 'other' type in certificate aux info to a STACK_OF
197 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
198 the required ASN1 format: arbitrary types determined by an OID.
199 [Steve Henson]
200
201 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
202 argument to 'req'. This is not because the function is newer or
203 better than others it just uses the work 'NEW' in the certificate
204 request header lines. Some software needs this.
205 [Steve Henson]
206
207 *) Reorganise password command line arguments: now passwords can be
208 obtained from various sources. Delete the PEM_cb function and make
209 it the default behaviour: i.e. if the callback is NULL and the
210 usrdata argument is not NULL interpret it as a null terminated pass
211 phrase. If usrdata and the callback are NULL then the pass phrase
212 is prompted for as usual.
213 [Steve Henson]
214
215 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
216 the support is automatically enabled. The resulting binaries will
217 autodetect the card and use it if present.
218 [Ben Laurie and Compaq Inc.]
219
220 *) Work around for Netscape hang bug. This sends certificate request
221 and server done in one record. Since this is perfectly legal in the
222 SSL/TLS protocol it isn't a "bug" option and is on by default. See
223 the bugs/SSLv3 entry for more info.
224 [Steve Henson]
225
226 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
227 [Andy Polyakov]
228
229 *) Add -rand argument to smime and pkcs12 applications and read/write
230 of seed file.
231 [Steve Henson]
232
233 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
234 [Bodo Moeller]
235
236 *) Add command line password options to the remaining applications.
237 [Steve Henson]
238
239 *) Bug fix for BN_div_recp() for numerators with an even number of
240 bits.
241 [Ulf Möller]
242
243 *) More tests in bntest.c, and changed test_bn output.
244 [Ulf Möller]
245
246 *) ./config recognizes MacOS X now.
247 [Andy Polyakov]
248
249 *) Bug fix for BN_div() when the first words of num and divsor are
250 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
251 [Ulf Möller]
252
253 *) Add support for various broken PKCS#8 formats, and command line
254 options to produce them.
255 [Steve Henson]
256
257 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
258 get temporary BIGNUMs from a BN_CTX.
259 [Ulf Möller]
260
261 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
262 for p == 0.
263 [Ulf Möller]
264
265 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
266 include a #define from the old name to the new. The original intent
267 was that statically linked binaries could for example just call
268 SSLeay_add_all_ciphers() to just add ciphers to the table and not
269 link with digests. This never worked becayse SSLeay_add_all_digests()
270 and SSLeay_add_all_ciphers() were in the same source file so calling
271 one would link with the other. They are now in separate source files.
272 [Steve Henson]
273
274 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
275 [Steve Henson]
276
277 *) Use a less unusual form of the Miller-Rabin primality test (it used
278 a binary algorithm for exponentiation integrated into the Miller-Rabin
279 loop, our standard modexp algorithms are faster).
280 [Bodo Moeller]
281
282 *) Support for the EBCDIC character set completed.
283 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
284
285 *) Source code cleanups: use const where appropriate, eliminate casts,
286 use void * instead of char * in lhash.
287 [Ulf Möller]
288
289 *) Bugfix: ssl3_send_server_key_exchange was not restartable
290 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
291 this the server could overwrite ephemeral keys that the client
292 has already seen).
293 [Bodo Moeller]
294
295 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
296 using 50 iterations of the Rabin-Miller test.
297
298 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
299 iterations of the Rabin-Miller test as required by the appendix
300 to FIPS PUB 186[-1]) instead of DSA_is_prime.
301 As BN_is_prime_fasttest includes trial division, DSA parameter
302 generation becomes much faster.
303
304 This implies a change for the callback functions in DSA_is_prime
305 and DSA_generate_parameters: The callback function is called once
306 for each positive witness in the Rabin-Miller test, not just
307 occasionally in the inner loop; and the parameters to the
308 callback function now provide an iteration count for the outer
309 loop rather than for the current invocation of the inner loop.
310 DSA_generate_parameters additionally can call the callback
311 function with an 'iteration count' of -1, meaning that a
312 candidate has passed the trial division test (when q is generated
313 from an application-provided seed, trial division is skipped).
314 [Bodo Moeller]
315
316 *) New function BN_is_prime_fasttest that optionally does trial
317 division before starting the Rabin-Miller test and has
318 an additional BN_CTX * argument (whereas BN_is_prime always
319 has to allocate at least one BN_CTX).
320 'callback(1, -1, cb_arg)' is called when a number has passed the
321 trial division stage.
322 [Bodo Moeller]
323
324 *) Fix for bug in CRL encoding. The validity dates weren't being handled
325 as ASN1_TIME.
326 [Steve Henson]
327
328 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
329 [Steve Henson]
330
331 *) New function BN_pseudo_rand().
332 [Ulf Möller]
333
334 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
335 bignum version of BN_from_montgomery() with the working code from
336 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
337 the comments.
338 [Ulf Möller]
339
340 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
341 made it impossible to use the same SSL_SESSION data structure in
342 SSL2 clients in multiple threads.
343 [Bodo Moeller]
344
345 *) The return value of RAND_load_file() no longer counts bytes obtained
346 by stat(). RAND_load_file(..., -1) is new and uses the complete file
347 to seed the PRNG (previously an explicit byte count was required).
348 [Ulf Möller, Bodo Möller]
349
350 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
351 used (char *) instead of (void *) and had casts all over the place.
352 [Steve Henson]
353
354 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
355 [Ulf Möller]
356
357 *) Retain source code compatibility for BN_prime_checks macro:
358 BN_is_prime(..., BN_prime_checks, ...) now uses
359 BN_prime_checks_for_size to determine the appropriate number of
360 Rabin-Miller iterations.
361 [Ulf Möller]
362
363 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
364 DH_CHECK_P_NOT_SAFE_PRIME.
365 (Check if this is true? OpenPGP calls them "strong".)
366 [Ulf Möller]
367
368 *) Merge the functionality of "dh" and "gendh" programs into a new program
369 "dhparam". The old programs are retained for now but will handle DH keys
370 (instead of parameters) in future.
371 [Steve Henson]
372
373 *) Make the ciphers, s_server and s_client programs check the return values
374 when a new cipher list is set.
375 [Steve Henson]
376
377 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
378 ciphers. Before when the 56bit ciphers were enabled the sorting was
379 wrong.
380
381 The syntax for the cipher sorting has been extended to support sorting by
382 cipher-strength (using the strength_bits hard coded in the tables).
383 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
384
385 Fix a bug in the cipher-command parser: when supplying a cipher command
386 string with an "undefined" symbol (neither command nor alphanumeric
387 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
388 an error is flagged.
389
390 Due to the strength-sorting extension, the code of the
391 ssl_create_cipher_list() function was completely rearranged. I hope that
392 the readability was also increased :-)
393 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
394
395 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
396 for the first serial number and places 2 in the serial number file. This
397 avoids problems when the root CA is created with serial number zero and
398 the first user certificate has the same issuer name and serial number
399 as the root CA.
400 [Steve Henson]
401
402 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
403 the new code. Add documentation for this stuff.
404 [Steve Henson]
405
406 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
407 X509_*() to X509at_*() on the grounds that they don't handle X509
408 structures and behave in an analagous way to the X509v3 functions:
409 they shouldn't be called directly but wrapper functions should be used
410 instead.
411
412 So we also now have some wrapper functions that call the X509at functions
413 when passed certificate requests. (TO DO: similar things can be done with
414 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
415 things. Some of these need some d2i or i2d and print functionality
416 because they handle more complex structures.)
417 [Steve Henson]
418
419 *) Add missing #ifndefs that caused missing symbols when building libssl
420 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
421 NO_RSA in ssl/s2*.c.
422 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
423
424 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
425 has a return value which indicates the quality of the random data
426 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
427 error queue. New function RAND_pseudo_bytes() generates output that is
428 guaranteed to be unique but not unpredictable. RAND_add is like
429 RAND_seed, but takes an extra argument for an entropy estimate
430 (RAND_seed always assumes full entropy).
431 [Ulf Möller]
432
433 *) Do more iterations of Rabin-Miller probable prime test (specifically,
434 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
435 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
436 in crypto/bn/bn_prime.c for the complete table). This guarantees a
437 false-positive rate of at most 2^-80 for random input.
438 [Bodo Moeller]
439
440 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
441 [Bodo Moeller]
442
443 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
444 in the 0.9.5 release), this returns the chain
445 from an X509_CTX structure with a dup of the stack and all
446 the X509 reference counts upped: so the stack will exist
447 after X509_CTX_cleanup() has been called. Modify pkcs12.c
448 to use this.
449
450 Also make SSL_SESSION_print() print out the verify return
451 code.
452 [Steve Henson]
453
454 *) Add manpage for the pkcs12 command. Also change the default
455 behaviour so MAC iteration counts are used unless the new
456 -nomaciter option is used. This improves file security and
457 only older versions of MSIE (4.0 for example) need it.
458 [Steve Henson]
459
460 *) Honor the no-xxx Configure options when creating .DEF files.
461 [Ulf Möller]
462
463 *) Add PKCS#10 attributes to field table: challengePassword,
464 unstructuredName and unstructuredAddress. These are taken from
465 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
466 international characters are used.
467
468 More changes to X509_ATTRIBUTE code: allow the setting of types
469 based on strings. Remove the 'loc' parameter when adding
470 attributes because these will be a SET OF encoding which is sorted
471 in ASN1 order.
472 [Steve Henson]
473
474 *) Initial changes to the 'req' utility to allow request generation
475 automation. This will allow an application to just generate a template
476 file containing all the field values and have req construct the
477 request.
478
479 Initial support for X509_ATTRIBUTE handling. Stacks of these are
480 used all over the place including certificate requests and PKCS#7
481 structures. They are currently handled manually where necessary with
482 some primitive wrappers for PKCS#7. The new functions behave in a
483 manner analogous to the X509 extension functions: they allow
484 attributes to be looked up by NID and added.
485
486 Later something similar to the X509V3 code would be desirable to
487 automatically handle the encoding, decoding and printing of the
488 more complex types. The string types like challengePassword can
489 be handled by the string table functions.
490
491 Also modified the multi byte string table handling. Now there is
492 a 'global mask' which masks out certain types. The table itself
493 can use the flag STABLE_NO_MASK to ignore the mask setting: this
494 is useful when for example there is only one permissible type
495 (as in countryName) and using the mask might result in no valid
496 types at all.
497 [Steve Henson]
498
499 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
500 SSL_get_peer_finished to allow applications to obtain the latest
501 Finished messages sent to the peer or expected from the peer,
502 respectively. (SSL_get_peer_finished is usually the Finished message
503 actually received from the peer, otherwise the protocol will be aborted.)
504
505 As the Finished message are message digests of the complete handshake
506 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
507 be used for external authentication procedures when the authentication
508 provided by SSL/TLS is not desired or is not enough.
509 [Bodo Moeller]
510
511 *) Enhanced support for Alpha Linux is added. Now ./config checks if
512 the host supports BWX extension and if Compaq C is present on the
513 $PATH. Just exploiting of the BWX extension results in 20-30%
514 performance kick for some algorithms, e.g. DES and RC4 to mention
515 a couple. Compaq C in turn generates ~20% faster code for MD5 and
516 SHA1.
517 [Andy Polyakov]
518
519 *) Add support for MS "fast SGC". This is arguably a violation of the
520 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
521 weak crypto and after checking the certificate is SGC a second one
522 with strong crypto. MS SGC stops the first handshake after receiving
523 the server certificate message and sends a second client hello. Since
524 a server will typically do all the time consuming operations before
525 expecting any further messages from the client (server key exchange
526 is the most expensive) there is little difference between the two.
527
528 To get OpenSSL to support MS SGC we have to permit a second client
529 hello message after we have sent server done. In addition we have to
530 reset the MAC if we do get this second client hello.
531 [Steve Henson]
532
533 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
534 if a DER encoded private key is RSA or DSA traditional format. Changed
535 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
536 format DER encoded private key. Newer code should use PKCS#8 format which
537 has the key type encoded in the ASN1 structure. Added DER private key
538 support to pkcs8 application.
539 [Steve Henson]
540
541 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
542 ciphersuites has been selected (as required by the SSL 3/TLS 1
543 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
544 is set, we interpret this as a request to violate the specification
545 (the worst that can happen is a handshake failure, and 'correct'
546 behaviour would result in a handshake failure anyway).
547 [Bodo Moeller]
548
549 *) In SSL_CTX_add_session, take into account that there might be multiple
550 SSL_SESSION structures with the same session ID (e.g. when two threads
551 concurrently obtain them from an external cache).
552 The internal cache can handle only one SSL_SESSION with a given ID,
553 so if there's a conflict, we now throw out the old one to achieve
554 consistency.
555 [Bodo Moeller]
556
557 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
558 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
559 some routines that use cipher OIDs: some ciphers do not have OIDs
560 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
561 example.
562 [Steve Henson]
563
564 *) Simplify the trust setting structure and code. Now we just have
565 two sequences of OIDs for trusted and rejected settings. These will
566 typically have values the same as the extended key usage extension
567 and any application specific purposes.
568
569 The trust checking code now has a default behaviour: it will just
570 check for an object with the same NID as the passed id. Functions can
571 be provided to override either the default behaviour or the behaviour
572 for a given id. SSL client, server and email already have functions
573 in place for compatibility: they check the NID and also return "trusted"
574 if the certificate is self signed.
575 [Steve Henson]
576
577 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
578 traditional format into an EVP_PKEY structure.
579 [Steve Henson]
580
581 *) Add a password callback function PEM_cb() which either prompts for
582 a password if usr_data is NULL or otherwise assumes it is a null
583 terminated password. Allow passwords to be passed on command line
584 environment or config files in a few more utilities.
585 [Steve Henson]
586
587 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
588 keys. Add some short names for PKCS#8 PBE algorithms and allow them
589 to be specified on the command line for the pkcs8 and pkcs12 utilities.
590 Update documentation.
591 [Steve Henson]
592
593 *) Support for ASN1 "NULL" type. This could be handled before by using
594 ASN1_TYPE but there wasn't any function that would try to read a NULL
595 and produce an error if it couldn't. For compatibility we also have
596 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
597 don't allocate anything because they don't need to.
598 [Steve Henson]
599
600 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
601 for details.
602 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
603
604 *) Rebuild of the memory allocation routines used by OpenSSL code and
605 possibly others as well. The purpose is to make an interface that
606 provide hooks so anyone can build a separate set of allocation and
607 deallocation routines to be used by OpenSSL, for example memory
608 pool implementations, or something else, which was previously hard
609 since Malloc(), Realloc() and Free() were defined as macros having
610 the values malloc, realloc and free, respectively (except for Win32
611 compilations). The same is provided for memory debugging code.
612 OpenSSL already comes with functionality to find memory leaks, but
613 this gives people a chance to debug other memory problems.
614
615 With these changes, a new set of functions and macros have appeared:
616
617 CRYPTO_set_mem_debug_functions() [F]
618 CRYPTO_get_mem_debug_functions() [F]
619 CRYPTO_dbg_set_options() [F]
620 CRYPTO_dbg_get_options() [F]
621 CRYPTO_malloc_debug_init() [M]
622
623 The memory debug functions are NULL by default, unless the library
624 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
625 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
626 gives the standard debugging functions that come with OpenSSL) or
627 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
628 provided by the library user) must be used. When the standard
629 debugging functions are used, CRYPTO_dbg_set_options can be used to
630 request additional information:
631 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
632 the CRYPTO_MDEBUG_xxx macro when compiling the library.
633
634 Also, things like CRYPTO_set_mem_functions will always give the
635 expected result (the new set of functions is used for allocation
636 and deallocation) at all times, regardless of platform and compiler
637 options.
638
639 To finish it up, some functions that were never use in any other
640 way than through macros have a new API and new semantic:
641
642 CRYPTO_dbg_malloc()
643 CRYPTO_dbg_realloc()
644 CRYPTO_dbg_free()
645
646 All macros of value have retained their old syntax.
647 [Richard Levitte and Bodo Moeller]
648
649 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
650 ordering of SMIMECapabilities wasn't in "strength order" and there
651 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
652 algorithm.
653 [Steve Henson]
654
655 *) Some ASN1 types with illegal zero length encoding (INTEGER,
656 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
657 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
658
659 *) Merge in my S/MIME library for OpenSSL. This provides a simple
660 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
661 functionality to handle multipart/signed properly) and a utility
662 called 'smime' to call all this stuff. This is based on code I
663 originally wrote for Celo who have kindly allowed it to be
664 included in OpenSSL.
665 [Steve Henson]
666
667 *) Add variants des_set_key_checked and des_set_key_unchecked of
668 des_set_key (aka des_key_sched). Global variable des_check_key
669 decides which of these is called by des_set_key; this way
670 des_check_key behaves as it always did, but applications and
671 the library itself, which was buggy for des_check_key == 1,
672 have a cleaner way to pick the version they need.
673 [Bodo Moeller]
674
675 *) New function PKCS12_newpass() which changes the password of a
676 PKCS12 structure.
677 [Steve Henson]
678
679 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
680 dynamic mix. In both cases the ids can be used as an index into the
681 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
682 functions so they accept a list of the field values and the
683 application doesn't need to directly manipulate the X509_TRUST
684 structure.
685 [Steve Henson]
686
687 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
688 need initialising.
689 [Steve Henson]
690
691 *) Modify the way the V3 extension code looks up extensions. This now
692 works in a similar way to the object code: we have some "standard"
693 extensions in a static table which is searched with OBJ_bsearch()
694 and the application can add dynamic ones if needed. The file
695 crypto/x509v3/ext_dat.h now has the info: this file needs to be
696 updated whenever a new extension is added to the core code and kept
697 in ext_nid order. There is a simple program 'tabtest.c' which checks
698 this. New extensions are not added too often so this file can readily
699 be maintained manually.
700
701 There are two big advantages in doing things this way. The extensions
702 can be looked up immediately and no longer need to be "added" using
703 X509V3_add_standard_extensions(): this function now does nothing.
704 [Side note: I get *lots* of email saying the extension code doesn't
705 work because people forget to call this function]
706 Also no dynamic allocation is done unless new extensions are added:
707 so if we don't add custom extensions there is no need to call
708 X509V3_EXT_cleanup().
709 [Steve Henson]
710
711 *) Modify enc utility's salting as follows: make salting the default. Add a
712 magic header, so unsalted files fail gracefully instead of just decrypting
713 to garbage. This is because not salting is a big security hole, so people
714 should be discouraged from doing it.
715 [Ben Laurie]
716
717 *) Fixes and enhancements to the 'x509' utility. It allowed a message
718 digest to be passed on the command line but it only used this
719 parameter when signing a certificate. Modified so all relevant
720 operations are affected by the digest parameter including the
721 -fingerprint and -x509toreq options. Also -x509toreq choked if a
722 DSA key was used because it didn't fix the digest.
723 [Steve Henson]
724
725 *) Initial certificate chain verify code. Currently tests the untrusted
726 certificates for consistency with the verify purpose (which is set
727 when the X509_STORE_CTX structure is set up) and checks the pathlength.
728
729 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
730 this is because it will reject chains with invalid extensions whereas
731 every previous version of OpenSSL and SSLeay made no checks at all.
732
733 Trust code: checks the root CA for the relevant trust settings. Trust
734 settings have an initial value consistent with the verify purpose: e.g.
735 if the verify purpose is for SSL client use it expects the CA to be
736 trusted for SSL client use. However the default value can be changed to
737 permit custom trust settings: one example of this would be to only trust
738 certificates from a specific "secure" set of CAs.
739
740 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
741 which should be used for version portability: especially since the
742 verify structure is likely to change more often now.
743
744 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
745 to set them. If not set then assume SSL clients will verify SSL servers
746 and vice versa.
747
748 Two new options to the verify program: -untrusted allows a set of
749 untrusted certificates to be passed in and -purpose which sets the
750 intended purpose of the certificate. If a purpose is set then the
751 new chain verify code is used to check extension consistency.
752 [Steve Henson]
753
754 *) Support for the authority information access extension.
755 [Steve Henson]
756
757 *) Modify RSA and DSA PEM read routines to transparently handle
758 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
759 public keys in a format compatible with certificate
760 SubjectPublicKeyInfo structures. Unfortunately there were already
761 functions called *_PublicKey_* which used various odd formats so
762 these are retained for compatibility: however the DSA variants were
763 never in a public release so they have been deleted. Changed dsa/rsa
764 utilities to handle the new format: note no releases ever handled public
765 keys so we should be OK.
766
767 The primary motivation for this change is to avoid the same fiasco
768 that dogs private keys: there are several incompatible private key
769 formats some of which are standard and some OpenSSL specific and
770 require various evil hacks to allow partial transparent handling and
771 even then it doesn't work with DER formats. Given the option anything
772 other than PKCS#8 should be dumped: but the other formats have to
773 stay in the name of compatibility.
774
775 With public keys and the benefit of hindsight one standard format
776 is used which works with EVP_PKEY, RSA or DSA structures: though
777 it clearly returns an error if you try to read the wrong kind of key.
778
779 Added a -pubkey option to the 'x509' utility to output the public key.
780 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
781 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
782 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
783 that do the same as the EVP_PKEY_assign_*() except they up the
784 reference count of the added key (they don't "swallow" the
785 supplied key).
786 [Steve Henson]
787
788 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
789 CRLs would fail if the file contained no certificates or no CRLs:
790 added a new function to read in both types and return the number
791 read: this means that if none are read it will be an error. The
792 DER versions of the certificate and CRL reader would always fail
793 because it isn't possible to mix certificates and CRLs in DER format
794 without choking one or the other routine. Changed this to just read
795 a certificate: this is the best we can do. Also modified the code
796 in apps/verify.c to take notice of return codes: it was previously
797 attempting to read in certificates from NULL pointers and ignoring
798 any errors: this is one reason why the cert and CRL reader seemed
799 to work. It doesn't check return codes from the default certificate
800 routines: these may well fail if the certificates aren't installed.
801 [Steve Henson]
802
803 *) Code to support otherName option in GeneralName.
804 [Steve Henson]
805
806 *) First update to verify code. Change the verify utility
807 so it warns if it is passed a self signed certificate:
808 for consistency with the normal behaviour. X509_verify
809 has been modified to it will now verify a self signed
810 certificate if *exactly* the same certificate appears
811 in the store: it was previously impossible to trust a
812 single self signed certificate. This means that:
813 openssl verify ss.pem
814 now gives a warning about a self signed certificate but
815 openssl verify -CAfile ss.pem ss.pem
816 is OK.
817 [Steve Henson]
818
819 *) For servers, store verify_result in SSL_SESSION data structure
820 (and add it to external session representation).
821 This is needed when client certificate verifications fails,
822 but an application-provided verification callback (set by
823 SSL_CTX_set_cert_verify_callback) allows accepting the session
824 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
825 but returns 1): When the session is reused, we have to set
826 ssl->verify_result to the appropriate error code to avoid
827 security holes.
828 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
829
830 *) Fix a bug in the new PKCS#7 code: it didn't consider the
831 case in PKCS7_dataInit() where the signed PKCS7 structure
832 didn't contain any existing data because it was being created.
833 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
834
835 *) Add a salt to the key derivation routines in enc.c. This
836 forms the first 8 bytes of the encrypted file. Also add a
837 -S option to allow a salt to be input on the command line.
838 [Steve Henson]
839
840 *) New function X509_cmp(). Oddly enough there wasn't a function
841 to compare two certificates. We do this by working out the SHA1
842 hash and comparing that. X509_cmp() will be needed by the trust
843 code.
844 [Steve Henson]
845
846 *) SSL_get1_session() is like SSL_get_session(), but increments
847 the reference count in the SSL_SESSION returned.
848 [Geoff Thorpe <geoff@eu.c2.net>]
849
850 *) Fix for 'req': it was adding a null to request attributes.
851 Also change the X509_LOOKUP and X509_INFO code to handle
852 certificate auxiliary information.
853 [Steve Henson]
854
855 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
856 the 'enc' command.
857 [Steve Henson]
858
859 *) Add the possibility to add extra information to the memory leak
860 detecting output, to form tracebacks, showing from where each
861 allocation was originated: CRYPTO_push_info("constant string") adds
862 the string plus current file name and line number to a per-thread
863 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
864 is like calling CYRPTO_pop_info() until the stack is empty.
865 Also updated memory leak detection code to be multi-thread-safe.
866 [Richard Levitte]
867
868 *) Add options -text and -noout to pkcs7 utility and delete the
869 encryption options which never did anything. Update docs.
870 [Steve Henson]
871
872 *) Add options to some of the utilities to allow the pass phrase
873 to be included on either the command line (not recommended on
874 OSes like Unix) or read from the environment. Update the
875 manpages and fix a few bugs.
876 [Steve Henson]
877
878 *) Add a few manpages for some of the openssl commands.
879 [Steve Henson]
880
881 *) Fix the -revoke option in ca. It was freeing up memory twice,
882 leaking and not finding already revoked certificates.
883 [Steve Henson]
884
885 *) Extensive changes to support certificate auxiliary information.
886 This involves the use of X509_CERT_AUX structure and X509_AUX
887 functions. An X509_AUX function such as PEM_read_X509_AUX()
888 can still read in a certificate file in the usual way but it
889 will also read in any additional "auxiliary information". By
890 doing things this way a fair degree of compatibility can be
891 retained: existing certificates can have this information added
892 using the new 'x509' options.
893
894 Current auxiliary information includes an "alias" and some trust
895 settings. The trust settings will ultimately be used in enhanced
896 certificate chain verification routines: currently a certificate
897 can only be trusted if it is self signed and then it is trusted
898 for all purposes.
899 [Steve Henson]
900
901 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
902 The problem was that one of the replacement routines had not been working
903 since SSLeay releases. For now the offending routine has been replaced
904 with non-optimised assembler. Even so, this now gives around 95%
905 performance improvement for 1024 bit RSA signs.
906 [Mark Cox]
907
908 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
909 handling. Most clients have the effective key size in bits equal to
910 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
911 A few however don't do this and instead use the size of the decrypted key
912 to determine the RC2 key length and the AlgorithmIdentifier to determine
913 the effective key length. In this case the effective key length can still
914 be 40 bits but the key length can be 168 bits for example. This is fixed
915 by manually forcing an RC2 key into the EVP_PKEY structure because the
916 EVP code can't currently handle unusual RC2 key sizes: it always assumes
917 the key length and effective key length are equal.
918 [Steve Henson]
919
920 *) Add a bunch of functions that should simplify the creation of
921 X509_NAME structures. Now you should be able to do:
922 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
923 and have it automatically work out the correct field type and fill in
924 the structures. The more adventurous can try:
925 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
926 and it will (hopefully) work out the correct multibyte encoding.
927 [Steve Henson]
928
929 *) Change the 'req' utility to use the new field handling and multibyte
930 copy routines. Before the DN field creation was handled in an ad hoc
931 way in req, ca, and x509 which was rather broken and didn't support
932 BMPStrings or UTF8Strings. Since some software doesn't implement
933 BMPStrings or UTF8Strings yet, they can be enabled using the config file
934 using the dirstring_type option. See the new comment in the default
935 openssl.cnf for more info.
936 [Steve Henson]
937
938 *) Make crypto/rand/md_rand.c more robust:
939 - Assure unique random numbers after fork().
940 - Make sure that concurrent threads access the global counter and
941 md serializably so that we never lose entropy in them
942 or use exactly the same state in multiple threads.
943 Access to the large state is not always serializable because
944 the additional locking could be a performance killer, and
945 md should be large enough anyway.
946 [Bodo Moeller]
947
948 *) New file apps/app_rand.c with commonly needed functionality
949 for handling the random seed file.
950
951 Use the random seed file in some applications that previously did not:
952 ca,
953 dsaparam -genkey (which also ignored its '-rand' option),
954 s_client,
955 s_server,
956 x509 (when signing).
957 Except on systems with /dev/urandom, it is crucial to have a random
958 seed file at least for key creation, DSA signing, and for DH exchanges;
959 for RSA signatures we could do without one.
960
961 gendh and gendsa (unlike genrsa) used to read only the first byte
962 of each file listed in the '-rand' option. The function as previously
963 found in genrsa is now in app_rand.c and is used by all programs
964 that support '-rand'.
965 [Bodo Moeller]
966
967 *) In RAND_write_file, use mode 0600 for creating files;
968 don't just chmod when it may be too late.
969 [Bodo Moeller]
970
971 *) Report an error from X509_STORE_load_locations
972 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
973 [Bill Perry]
974
975 *) New function ASN1_mbstring_copy() this copies a string in either
976 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
977 into an ASN1_STRING type. A mask of permissible types is passed
978 and it chooses the "minimal" type to use or an error if not type
979 is suitable.
980 [Steve Henson]
981
982 *) Add function equivalents to the various macros in asn1.h. The old
983 macros are retained with an M_ prefix. Code inside the library can
984 use the M_ macros. External code (including the openssl utility)
985 should *NOT* in order to be "shared library friendly".
986 [Steve Henson]
987
988 *) Add various functions that can check a certificate's extensions
989 to see if it usable for various purposes such as SSL client,
990 server or S/MIME and CAs of these types. This is currently
991 VERY EXPERIMENTAL but will ultimately be used for certificate chain
992 verification. Also added a -purpose flag to x509 utility to
993 print out all the purposes.
994 [Steve Henson]
995
996 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
997 functions.
998 [Steve Henson]
999
1000 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
1001 for, obtain and decode and extension and obtain its critical flag.
1002 This allows all the necessary extension code to be handled in a
1003 single function call.
1004 [Steve Henson]
1005
1006 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
1007 platforms. See crypto/rc4/rc4_enc.c for further details.
1008 [Andy Polyakov]
1009
1010 *) New -noout option to asn1parse. This causes no output to be produced
1011 its main use is when combined with -strparse and -out to extract data
1012 from a file (which may not be in ASN.1 format).
1013 [Steve Henson]
1014
1015 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
1016 when producing the local key id.
1017 [Richard Levitte <levitte@stacken.kth.se>]
1018
1019 *) New option -dhparam in s_server. This allows a DH parameter file to be
1020 stated explicitly. If it is not stated then it tries the first server
1021 certificate file. The previous behaviour hard coded the filename
1022 "server.pem".
1023 [Steve Henson]
1024
1025 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
1026 a public key to be input or output. For example:
1027 openssl rsa -in key.pem -pubout -out pubkey.pem
1028 Also added necessary DSA public key functions to handle this.
1029 [Steve Henson]
1030
1031 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
1032 in the message. This was handled by allowing
1033 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
1034 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
1035
1036 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
1037 to the end of the strings whereas this didn't. This would cause problems
1038 if strings read with d2i_ASN1_bytes() were later modified.
1039 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
1040
1041 *) Fix for base64 decode bug. When a base64 bio reads only one line of
1042 data and it contains EOF it will end up returning an error. This is
1043 caused by input 46 bytes long. The cause is due to the way base64
1044 BIOs find the start of base64 encoded data. They do this by trying a
1045 trial decode on each line until they find one that works. When they
1046 do a flag is set and it starts again knowing it can pass all the
1047 data directly through the decoder. Unfortunately it doesn't reset
1048 the context it uses. This means that if EOF is reached an attempt
1049 is made to pass two EOFs through the context and this causes the
1050 resulting error. This can also cause other problems as well. As is
1051 usual with these problems it takes *ages* to find and the fix is
1052 trivial: move one line.
1053 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
1054
1055 *) Ugly workaround to get s_client and s_server working under Windows. The
1056 old code wouldn't work because it needed to select() on sockets and the
1057 tty (for keypresses and to see if data could be written). Win32 only
1058 supports select() on sockets so we select() with a 1s timeout on the
1059 sockets and then see if any characters are waiting to be read, if none
1060 are present then we retry, we also assume we can always write data to
1061 the tty. This isn't nice because the code then blocks until we've
1062 received a complete line of data and it is effectively polling the
1063 keyboard at 1s intervals: however it's quite a bit better than not
1064 working at all :-) A dedicated Windows application might handle this
1065 with an event loop for example.
1066 [Steve Henson]
1067
1068 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
1069 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
1070 will be called when RSA_sign() and RSA_verify() are used. This is useful
1071 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
1072 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
1073 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
1074 This necessitated the support of an extra signature type NID_md5_sha1
1075 for SSL signatures and modifications to the SSL library to use it instead
1076 of calling RSA_public_decrypt() and RSA_private_encrypt().
1077 [Steve Henson]
1078
1079 *) Add new -verify -CAfile and -CApath options to the crl program, these
1080 will lookup a CRL issuers certificate and verify the signature in a
1081 similar way to the verify program. Tidy up the crl program so it
1082 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
1083 less strict. It will now permit CRL extensions even if it is not
1084 a V2 CRL: this will allow it to tolerate some broken CRLs.
1085 [Steve Henson]
1086
1087 *) Initialize all non-automatic variables each time one of the openssl
1088 sub-programs is started (this is necessary as they may be started
1089 multiple times from the "OpenSSL>" prompt).
1090 [Lennart Bang, Bodo Moeller]
1091
1092 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
1093 removing all other RSA functionality (this is what NO_RSA does). This
1094 is so (for example) those in the US can disable those operations covered
1095 by the RSA patent while allowing storage and parsing of RSA keys and RSA
1096 key generation.
1097 [Steve Henson]
1098
1099 *) Non-copying interface to BIO pairs.
1100 (still largely untested)
1101 [Bodo Moeller]
1102
1103 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
1104 ASCII string. This was handled independently in various places before.
1105 [Steve Henson]
1106
1107 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
1108 UTF8 strings a character at a time.
1109 [Steve Henson]
1110
1111 *) Use client_version from client hello to select the protocol
1112 (s23_srvr.c) and for RSA client key exchange verification
1113 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
1114 [Bodo Moeller]
1115
1116 *) Add various utility functions to handle SPKACs, these were previously
1117 handled by poking round in the structure internals. Added new function
1118 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
1119 print, verify and generate SPKACs. Based on an original idea from
1120 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
1121 [Steve Henson]
1122
1123 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
1124 [Andy Polyakov]
1125
1126 *) Allow the config file extension section to be overwritten on the
1127 command line. Based on an original idea from Massimiliano Pala
1128 <madwolf@comune.modena.it>. The new option is called -extensions
1129 and can be applied to ca, req and x509. Also -reqexts to override
1130 the request extensions in req and -crlexts to override the crl extensions
1131 in ca.
1132 [Steve Henson]
1133
1134 *) Add new feature to the SPKAC handling in ca. Now you can include
1135 the same field multiple times by preceding it by "XXXX." for example:
1136 1.OU="Unit name 1"
1137 2.OU="Unit name 2"
1138 this is the same syntax as used in the req config file.
1139 [Steve Henson]
1140
1141 *) Allow certificate extensions to be added to certificate requests. These
1142 are specified in a 'req_extensions' option of the req section of the
1143 config file. They can be printed out with the -text option to req but
1144 are otherwise ignored at present.
1145 [Steve Henson]
1146
1147 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
1148 data read consists of only the final block it would not decrypted because
1149 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
1150 A misplaced 'break' also meant the decrypted final block might not be
1151 copied until the next read.
1152 [Steve Henson]
1153
1154 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
1155 a few extra parameters to the DH structure: these will be useful if
1156 for example we want the value of 'q' or implement X9.42 DH.
1157 [Steve Henson]
1158
1159 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
1160 provides hooks that allow the default DSA functions or functions on a
1161 "per key" basis to be replaced. This allows hardware acceleration and
1162 hardware key storage to be handled without major modification to the
1163 library. Also added low level modexp hooks and CRYPTO_EX structure and
1164 associated functions.
1165 [Steve Henson]
1166
1167 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
1168 as "read only": it can't be written to and the buffer it points to will
1169 not be freed. Reading from a read only BIO is much more efficient than
1170 a normal memory BIO. This was added because there are several times when
1171 an area of memory needs to be read from a BIO. The previous method was
1172 to create a memory BIO and write the data to it, this results in two
1173 copies of the data and an O(n^2) reading algorithm. There is a new
1174 function BIO_new_mem_buf() which creates a read only memory BIO from
1175 an area of memory. Also modified the PKCS#7 routines to use read only
1176 memory BIOs.
1177 [Steve Henson]
1178
1179 *) Bugfix: ssl23_get_client_hello did not work properly when called in
1180 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
1181 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
1182 but a retry condition occured while trying to read the rest.
1183 [Bodo Moeller]
1184
1185 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
1186 NID_pkcs7_encrypted by default: this was wrong since this should almost
1187 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
1188 the encrypted data type: this is a more sensible place to put it and it
1189 allows the PKCS#12 code to be tidied up that duplicated this
1190 functionality.
1191 [Steve Henson]
1192
1193 *) Changed obj_dat.pl script so it takes its input and output files on
1194 the command line. This should avoid shell escape redirection problems
1195 under Win32.
1196 [Steve Henson]
1197
1198 *) Initial support for certificate extension requests, these are included
1199 in things like Xenroll certificate requests. Included functions to allow
1200 extensions to be obtained and added.
1201 [Steve Henson]
1202
1203 *) -crlf option to s_client and s_server for sending newlines as
1204 CRLF (as required by many protocols).
1205 [Bodo Moeller]
1206
1207 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
1208
1209 *) Install libRSAglue.a when OpenSSL is built with RSAref.
1210 [Ralf S. Engelschall]
1211
1212 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
1213 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
1214
1215 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
1216 program.
1217 [Steve Henson]
1218
1219 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
1220 DH parameters/keys (q is lost during that conversion, but the resulting
1221 DH parameters contain its length).
1222
1223 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
1224 much faster than DH_generate_parameters (which creates parameters
1225 where p = 2*q + 1), and also the smaller q makes DH computations
1226 much more efficient (160-bit exponentiation instead of 1024-bit
1227 exponentiation); so this provides a convenient way to support DHE
1228 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
1229 utter importance to use
1230 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1231 or
1232 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1233 when such DH parameters are used, because otherwise small subgroup
1234 attacks may become possible!
1235 [Bodo Moeller]
1236
1237 *) Avoid memory leak in i2d_DHparams.
1238 [Bodo Moeller]
1239
1240 *) Allow the -k option to be used more than once in the enc program:
1241 this allows the same encrypted message to be read by multiple recipients.
1242 [Steve Henson]
1243
1244 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
1245 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
1246 it will always use the numerical form of the OID, even if it has a short
1247 or long name.
1248 [Steve Henson]
1249
1250 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
1251 method only got called if p,q,dmp1,dmq1,iqmp components were present,
1252 otherwise bn_mod_exp was called. In the case of hardware keys for example
1253 no private key components need be present and it might store extra data
1254 in the RSA structure, which cannot be accessed from bn_mod_exp.
1255 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
1256 private key operations.
1257 [Steve Henson]
1258
1259 *) Added support for SPARC Linux.
1260 [Andy Polyakov]
1261
1262 *) pem_password_cb function type incompatibly changed from
1263 typedef int pem_password_cb(char *buf, int size, int rwflag);
1264 to
1265 ....(char *buf, int size, int rwflag, void *userdata);
1266 so that applications can pass data to their callbacks:
1267 The PEM[_ASN1]_{read,write}... functions and macros now take an
1268 additional void * argument, which is just handed through whenever
1269 the password callback is called.
1270 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
1271
1272 New function SSL_CTX_set_default_passwd_cb_userdata.
1273
1274 Compatibility note: As many C implementations push function arguments
1275 onto the stack in reverse order, the new library version is likely to
1276 interoperate with programs that have been compiled with the old
1277 pem_password_cb definition (PEM_whatever takes some data that
1278 happens to be on the stack as its last argument, and the callback
1279 just ignores this garbage); but there is no guarantee whatsoever that
1280 this will work.
1281
1282 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
1283 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
1284 problems not only on Windows, but also on some Unix platforms.
1285 To avoid problematic command lines, these definitions are now in an
1286 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
1287 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
1288 [Bodo Moeller]
1289
1290 *) MIPS III/IV assembler module is reimplemented.
1291 [Andy Polyakov]
1292
1293 *) More DES library cleanups: remove references to srand/rand and
1294 delete an unused file.
1295 [Ulf Möller]
1296
1297 *) Add support for the the free Netwide assembler (NASM) under Win32,
1298 since not many people have MASM (ml) and it can be hard to obtain.
1299 This is currently experimental but it seems to work OK and pass all
1300 the tests. Check out INSTALL.W32 for info.
1301 [Steve Henson]
1302
1303 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
1304 without temporary keys kept an extra copy of the server key,
1305 and connections with temporary keys did not free everything in case
1306 of an error.
1307 [Bodo Moeller]
1308
1309 *) New function RSA_check_key and new openssl rsa option -check
1310 for verifying the consistency of RSA keys.
1311 [Ulf Moeller, Bodo Moeller]
1312
1313 *) Various changes to make Win32 compile work:
1314 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
1315 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
1316 comparison" warnings.
1317 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
1318 [Steve Henson]
1319
1320 *) Add a debugging option to PKCS#5 v2 key generation function: when
1321 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
1322 derived keys are printed to stderr.
1323 [Steve Henson]
1324
1325 *) Copy the flags in ASN1_STRING_dup().
1326 [Roman E. Pavlov <pre@mo.msk.ru>]
1327
1328 *) The x509 application mishandled signing requests containing DSA
1329 keys when the signing key was also DSA and the parameters didn't match.
1330
1331 It was supposed to omit the parameters when they matched the signing key:
1332 the verifying software was then supposed to automatically use the CA's
1333 parameters if they were absent from the end user certificate.
1334
1335 Omitting parameters is no longer recommended. The test was also
1336 the wrong way round! This was probably due to unusual behaviour in
1337 EVP_cmp_parameters() which returns 1 if the parameters match.
1338 This meant that parameters were omitted when they *didn't* match and
1339 the certificate was useless. Certificates signed with 'ca' didn't have
1340 this bug.
1341 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
1342
1343 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
1344 The interface is as follows:
1345 Applications can use
1346 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
1347 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
1348 "off" is now the default.
1349 The library internally uses
1350 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
1351 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
1352 to disable memory-checking temporarily.
1353
1354 Some inconsistent states that previously were possible (and were
1355 even the default) are now avoided.
1356
1357 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
1358 with each memory chunk allocated; this is occasionally more helpful
1359 than just having a counter.
1360
1361 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
1362
1363 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
1364 extensions.
1365 [Bodo Moeller]
1366
1367 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
1368 which largely parallels "options", but is for changing API behaviour,
1369 whereas "options" are about protocol behaviour.
1370 Initial "mode" flags are:
1371
1372 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
1373 a single record has been written.
1374 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
1375 retries use the same buffer location.
1376 (But all of the contents must be
1377 copied!)
1378 [Bodo Moeller]
1379
1380 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
1381 worked.
1382
1383 *) Fix problems with no-hmac etc.
1384 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
1385
1386 *) New functions RSA_get_default_method(), RSA_set_method() and
1387 RSA_get_method(). These allows replacement of RSA_METHODs without having
1388 to mess around with the internals of an RSA structure.
1389 [Steve Henson]
1390
1391 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
1392 Also really enable memory leak checks in openssl.c and in some
1393 test programs.
1394 [Chad C. Mulligan, Bodo Moeller]
1395
1396 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
1397 up the length of negative integers. This has now been simplified to just
1398 store the length when it is first determined and use it later, rather
1399 than trying to keep track of where data is copied and updating it to
1400 point to the end.
1401 [Steve Henson, reported by Brien Wheeler
1402 <bwheeler@authentica-security.com>]
1403
1404 *) Add a new function PKCS7_signatureVerify. This allows the verification
1405 of a PKCS#7 signature but with the signing certificate passed to the
1406 function itself. This contrasts with PKCS7_dataVerify which assumes the
1407 certificate is present in the PKCS#7 structure. This isn't always the
1408 case: certificates can be omitted from a PKCS#7 structure and be
1409 distributed by "out of band" means (such as a certificate database).
1410 [Steve Henson]
1411
1412 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
1413 function prototypes in pem.h, also change util/mkdef.pl to add the
1414 necessary function names.
1415 [Steve Henson]
1416
1417 *) mk1mf.pl (used by Windows builds) did not properly read the
1418 options set by Configure in the top level Makefile, and Configure
1419 was not even able to write more than one option correctly.
1420 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
1421 [Bodo Moeller]
1422
1423 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
1424 file to be loaded from a BIO or FILE pointer. The BIO version will
1425 for example allow memory BIOs to contain config info.
1426 [Steve Henson]
1427
1428 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
1429 Whoever hopes to achieve shared-library compatibility across versions
1430 must use this, not the compile-time macro.
1431 (Exercise 0.9.4: Which is the minimum library version required by
1432 such programs?)
1433 Note: All this applies only to multi-threaded programs, others don't
1434 need locks.
1435 [Bodo Moeller]
1436
1437 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
1438 through a BIO pair triggered the default case, i.e.
1439 SSLerr(...,SSL_R_UNKNOWN_STATE).
1440 [Bodo Moeller]
1441
1442 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
1443 can use the SSL library even if none of the specific BIOs is
1444 appropriate.
1445 [Bodo Moeller]
1446
1447 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
1448 for the encoded length.
1449 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
1450
1451 *) Add initial documentation of the X509V3 functions.
1452 [Steve Henson]
1453
1454 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
1455 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
1456 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
1457 secure PKCS#8 private key format with a high iteration count.
1458 [Steve Henson]
1459
1460 *) Fix determination of Perl interpreter: A perl or perl5
1461 _directory_ in $PATH was also accepted as the interpreter.
1462 [Ralf S. Engelschall]
1463
1464 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
1465 wrong with it but it was very old and did things like calling
1466 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
1467 unusual formatting.
1468 [Steve Henson]
1469
1470 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
1471 to use the new extension code.
1472 [Steve Henson]
1473
1474 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
1475 with macros. This should make it easier to change their form, add extra
1476 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
1477 constant.
1478 [Steve Henson]
1479
1480 *) Add to configuration table a new entry that can specify an alternative
1481 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
1482 according to Mark Crispin <MRC@Panda.COM>.
1483 [Bodo Moeller]
1484
1485 #if 0
1486 *) DES CBC did not update the IV. Weird.
1487 [Ben Laurie]
1488 #else
1489 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
1490 Changing the behaviour of the former might break existing programs --
1491 where IV updating is needed, des_ncbc_encrypt can be used.
1492 #endif
1493
1494 *) When bntest is run from "make test" it drives bc to check its
1495 calculations, as well as internally checking them. If an internal check
1496 fails, it needs to cause bc to give a non-zero result or make test carries
1497 on without noticing the failure. Fixed.
1498 [Ben Laurie]
1499
1500 *) DES library cleanups.
1501 [Ulf Möller]
1502
1503 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
1504 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
1505 ciphers. NOTE: although the key derivation function has been verified
1506 against some published test vectors it has not been extensively tested
1507 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
1508 of v2.0.
1509 [Steve Henson]
1510
1511 *) Instead of "mkdir -p", which is not fully portable, use new
1512 Perl script "util/mkdir-p.pl".
1513 [Bodo Moeller]
1514
1515 *) Rewrite the way password based encryption (PBE) is handled. It used to
1516 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
1517 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
1518 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
1519 the 'parameter' field of the AlgorithmIdentifier is passed to the
1520 underlying key generation function so it must do its own ASN1 parsing.
1521 This has also changed the EVP_PBE_CipherInit() function which now has a
1522 'parameter' argument instead of literal salt and iteration count values
1523 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
1524 [Steve Henson]
1525
1526 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
1527 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
1528 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
1529 KEY" because this clashed with PKCS#8 unencrypted string. Since this
1530 value was just used as a "magic string" and not used directly its
1531 value doesn't matter.
1532 [Steve Henson]
1533
1534 *) Introduce some semblance of const correctness to BN. Shame C doesn't
1535 support mutable.
1536 [Ben Laurie]
1537
1538 *) "linux-sparc64" configuration (ultrapenguin).
1539 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
1540 "linux-sparc" configuration.
1541 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
1542
1543 *) config now generates no-xxx options for missing ciphers.
1544 [Ulf Möller]
1545
1546 *) Support the EBCDIC character set (work in progress).
1547 File ebcdic.c not yet included because it has a different license.
1548 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1549
1550 *) Support BS2000/OSD-POSIX.
1551 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1552
1553 *) Make callbacks for key generation use void * instead of char *.
1554 [Ben Laurie]
1555
1556 *) Make S/MIME samples compile (not yet tested).
1557 [Ben Laurie]
1558
1559 *) Additional typesafe stacks.
1560 [Ben Laurie]
1561
1562 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
1563 [Bodo Moeller]
1564
1565
1566 Changes between 0.9.3 and 0.9.3a [29 May 1999]
1567
1568 *) New configuration variant "sco5-gcc".
1569
1570 *) Updated some demos.
1571 [Sean O Riordain, Wade Scholine]
1572
1573 *) Add missing BIO_free at exit of pkcs12 application.
1574 [Wu Zhigang]
1575
1576 *) Fix memory leak in conf.c.
1577 [Steve Henson]
1578
1579 *) Updates for Win32 to assembler version of MD5.
1580 [Steve Henson]
1581
1582 *) Set #! path to perl in apps/der_chop to where we found it
1583 instead of using a fixed path.
1584 [Bodo Moeller]
1585
1586 *) SHA library changes for irix64-mips4-cc.
1587 [Andy Polyakov]
1588
1589 *) Improvements for VMS support.
1590 [Richard Levitte]
1591
1592
1593 Changes between 0.9.2b and 0.9.3 [24 May 1999]
1594
1595 *) Bignum library bug fix. IRIX 6 passes "make test" now!
1596 This also avoids the problems with SC4.2 and unpatched SC5.
1597 [Andy Polyakov <appro@fy.chalmers.se>]
1598
1599 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
1600 These are required because of the typesafe stack would otherwise break
1601 existing code. If old code used a structure member which used to be STACK
1602 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
1603 sk_num or sk_value it would produce an error because the num, data members
1604 are not present in STACK_OF. Now it just produces a warning. sk_set
1605 replaces the old method of assigning a value to sk_value
1606 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
1607 that does this will no longer work (and should use sk_set instead) but
1608 this could be regarded as a "questionable" behaviour anyway.
1609 [Steve Henson]
1610
1611 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
1612 correctly handle encrypted S/MIME data.
1613 [Steve Henson]
1614
1615 *) Change type of various DES function arguments from des_cblock
1616 (which means, in function argument declarations, pointer to char)
1617 to des_cblock * (meaning pointer to array with 8 char elements),
1618 which allows the compiler to do more typechecking; it was like
1619 that back in SSLeay, but with lots of ugly casts.
1620
1621 Introduce new type const_des_cblock.
1622 [Bodo Moeller]
1623
1624 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
1625 problems: find RecipientInfo structure that matches recipient certificate
1626 and initialise the ASN1 structures properly based on passed cipher.
1627 [Steve Henson]
1628
1629 *) Belatedly make the BN tests actually check the results.
1630 [Ben Laurie]
1631
1632 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
1633 to and from BNs: it was completely broken. New compilation option
1634 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
1635 key elements as negative integers.
1636 [Steve Henson]
1637
1638 *) Reorganize and speed up MD5.
1639 [Andy Polyakov <appro@fy.chalmers.se>]
1640
1641 *) VMS support.
1642 [Richard Levitte <richard@levitte.org>]
1643
1644 *) New option -out to asn1parse to allow the parsed structure to be
1645 output to a file. This is most useful when combined with the -strparse
1646 option to examine the output of things like OCTET STRINGS.
1647 [Steve Henson]
1648
1649 *) Make SSL library a little more fool-proof by not requiring any longer
1650 that SSL_set_{accept,connect}_state be called before
1651 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
1652 in many applications because usually everything *appeared* to work as
1653 intended anyway -- now it really works as intended).
1654 [Bodo Moeller]
1655
1656 *) Move openssl.cnf out of lib/.
1657 [Ulf Möller]
1658
1659 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
1660 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
1661 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
1662 [Ralf S. Engelschall]
1663
1664 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
1665 handle PKCS#7 enveloped data properly.
1666 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
1667
1668 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
1669 copying pointers. The cert_st handling is changed by this in
1670 various ways (and thus what used to be known as ctx->default_cert
1671 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
1672 any longer when s->cert does not give us what we need).
1673 ssl_cert_instantiate becomes obsolete by this change.
1674 As soon as we've got the new code right (possibly it already is?),
1675 we have solved a couple of bugs of the earlier code where s->cert
1676 was used as if it could not have been shared with other SSL structures.
1677
1678 Note that using the SSL API in certain dirty ways now will result
1679 in different behaviour than observed with earlier library versions:
1680 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
1681 does not influence s as it used to.
1682
1683 In order to clean up things more thoroughly, inside SSL_SESSION
1684 we don't use CERT any longer, but a new structure SESS_CERT
1685 that holds per-session data (if available); currently, this is
1686 the peer's certificate chain and, for clients, the server's certificate
1687 and temporary key. CERT holds only those values that can have
1688 meaningful defaults in an SSL_CTX.
1689 [Bodo Moeller]
1690
1691 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
1692 from the internal representation. Various PKCS#7 fixes: remove some
1693 evil casts and set the enc_dig_alg field properly based on the signing
1694 key type.
1695 [Steve Henson]
1696
1697 *) Allow PKCS#12 password to be set from the command line or the
1698 environment. Let 'ca' get its config file name from the environment
1699 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
1700 and 'x509').
1701 [Steve Henson]
1702
1703 *) Allow certificate policies extension to use an IA5STRING for the
1704 organization field. This is contrary to the PKIX definition but
1705 VeriSign uses it and IE5 only recognises this form. Document 'x509'
1706 extension option.
1707 [Steve Henson]
1708
1709 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
1710 without disallowing inline assembler and the like for non-pedantic builds.
1711 [Ben Laurie]
1712
1713 *) Support Borland C++ builder.
1714 [Janez Jere <jj@void.si>, modified by Ulf Möller]
1715
1716 *) Support Mingw32.
1717 [Ulf Möller]
1718
1719 *) SHA-1 cleanups and performance enhancements.
1720 [Andy Polyakov <appro@fy.chalmers.se>]
1721
1722 *) Sparc v8plus assembler for the bignum library.
1723 [Andy Polyakov <appro@fy.chalmers.se>]
1724
1725 *) Accept any -xxx and +xxx compiler options in Configure.
1726 [Ulf Möller]
1727
1728 *) Update HPUX configuration.
1729 [Anonymous]
1730
1731 *) Add missing sk_<type>_unshift() function to safestack.h
1732 [Ralf S. Engelschall]
1733
1734 *) New function SSL_CTX_use_certificate_chain_file that sets the
1735 "extra_cert"s in addition to the certificate. (This makes sense
1736 only for "PEM" format files, as chains as a whole are not
1737 DER-encoded.)
1738 [Bodo Moeller]
1739
1740 *) Support verify_depth from the SSL API.
1741 x509_vfy.c had what can be considered an off-by-one-error:
1742 Its depth (which was not part of the external interface)
1743 was actually counting the number of certificates in a chain;
1744 now it really counts the depth.
1745 [Bodo Moeller]
1746
1747 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
1748 instead of X509err, which often resulted in confusing error
1749 messages since the error codes are not globally unique
1750 (e.g. an alleged error in ssl3_accept when a certificate
1751 didn't match the private key).
1752
1753 *) New function SSL_CTX_set_session_id_context that allows to set a default
1754 value (so that you don't need SSL_set_session_id_context for each
1755 connection using the SSL_CTX).
1756 [Bodo Moeller]
1757
1758 *) OAEP decoding bug fix.
1759 [Ulf Möller]
1760
1761 *) Support INSTALL_PREFIX for package builders, as proposed by
1762 David Harris.
1763 [Bodo Moeller]
1764
1765 *) New Configure options "threads" and "no-threads". For systems
1766 where the proper compiler options are known (currently Solaris
1767 and Linux), "threads" is the default.
1768 [Bodo Moeller]
1769
1770 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
1771 [Bodo Moeller]
1772
1773 *) Install various scripts to $(OPENSSLDIR)/misc, not to
1774 $(INSTALLTOP)/bin -- they shouldn't clutter directories
1775 such as /usr/local/bin.
1776 [Bodo Moeller]
1777
1778 *) "make linux-shared" to build shared libraries.
1779 [Niels Poppe <niels@netbox.org>]
1780
1781 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
1782 [Ulf Möller]
1783
1784 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
1785 extension adding in x509 utility.
1786 [Steve Henson]
1787
1788 *) Remove NOPROTO sections and error code comments.
1789 [Ulf Möller]
1790
1791 *) Partial rewrite of the DEF file generator to now parse the ANSI
1792 prototypes.
1793 [Steve Henson]
1794
1795 *) New Configure options --prefix=DIR and --openssldir=DIR.
1796 [Ulf Möller]
1797
1798 *) Complete rewrite of the error code script(s). It is all now handled
1799 by one script at the top level which handles error code gathering,
1800 header rewriting and C source file generation. It should be much better
1801 than the old method: it now uses a modified version of Ulf's parser to
1802 read the ANSI prototypes in all header files (thus the old K&R definitions
1803 aren't needed for error creation any more) and do a better job of
1804 translating function codes into names. The old 'ASN1 error code imbedded
1805 in a comment' is no longer necessary and it doesn't use .err files which
1806 have now been deleted. Also the error code call doesn't have to appear all
1807 on one line (which resulted in some large lines...).
1808 [Steve Henson]
1809
1810 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
1811 [Bodo Moeller]
1812
1813 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
1814 0 (which usually indicates a closed connection), but continue reading.
1815 [Bodo Moeller]
1816
1817 *) Fix some race conditions.
1818 [Bodo Moeller]
1819
1820 *) Add support for CRL distribution points extension. Add Certificate
1821 Policies and CRL distribution points documentation.
1822 [Steve Henson]
1823
1824 *) Move the autogenerated header file parts to crypto/opensslconf.h.
1825 [Ulf Möller]
1826
1827 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
1828 8 of keying material. Merlin has also confirmed interop with this fix
1829 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
1830 [Merlin Hughes <merlin@baltimore.ie>]
1831
1832 *) Fix lots of warnings.
1833 [Richard Levitte <levitte@stacken.kth.se>]
1834
1835 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
1836 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
1837 [Richard Levitte <levitte@stacken.kth.se>]
1838
1839 *) Fix problems with sizeof(long) == 8.
1840 [Andy Polyakov <appro@fy.chalmers.se>]
1841
1842 *) Change functions to ANSI C.
1843 [Ulf Möller]
1844
1845 *) Fix typos in error codes.
1846 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
1847
1848 *) Remove defunct assembler files from Configure.
1849 [Ulf Möller]
1850
1851 *) SPARC v8 assembler BIGNUM implementation.
1852 [Andy Polyakov <appro@fy.chalmers.se>]
1853
1854 *) Support for Certificate Policies extension: both print and set.
1855 Various additions to support the r2i method this uses.
1856 [Steve Henson]
1857
1858 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
1859 return a const string when you are expecting an allocated buffer.
1860 [Ben Laurie]
1861
1862 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
1863 types DirectoryString and DisplayText.
1864 [Steve Henson]
1865
1866 *) Add code to allow r2i extensions to access the configuration database,
1867 add an LHASH database driver and add several ctx helper functions.
1868 [Steve Henson]
1869
1870 *) Fix an evil bug in bn_expand2() which caused various BN functions to
1871 fail when they extended the size of a BIGNUM.
1872 [Steve Henson]
1873
1874 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
1875 support typesafe stack.
1876 [Steve Henson]
1877
1878 *) Fix typo in SSL_[gs]et_options().
1879 [Nils Frostberg <nils@medcom.se>]
1880
1881 *) Delete various functions and files that belonged to the (now obsolete)
1882 old X509V3 handling code.
1883 [Steve Henson]
1884
1885 *) New Configure option "rsaref".
1886 [Ulf Möller]
1887
1888 *) Don't auto-generate pem.h.
1889 [Bodo Moeller]
1890
1891 *) Introduce type-safe ASN.1 SETs.
1892 [Ben Laurie]
1893
1894 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
1895 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
1896
1897 *) Introduce type-safe STACKs. This will almost certainly break lots of code
1898 that links with OpenSSL (well at least cause lots of warnings), but fear
1899 not: the conversion is trivial, and it eliminates loads of evil casts. A
1900 few STACKed things have been converted already. Feel free to convert more.
1901 In the fullness of time, I'll do away with the STACK type altogether.
1902 [Ben Laurie]
1903
1904 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
1905 specified in <certfile> by updating the entry in the index.txt file.
1906 This way one no longer has to edit the index.txt file manually for
1907 revoking a certificate. The -revoke option does the gory details now.
1908 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
1909
1910 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
1911 `-text' option at all and this way the `-noout -text' combination was
1912 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
1913 [Ralf S. Engelschall]
1914
1915 *) Make sure a corresponding plain text error message exists for the
1916 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
1917 verify callback function determined that a certificate was revoked.
1918 [Ralf S. Engelschall]
1919
1920 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
1921 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
1922 all available cipers including rc5, which was forgotten until now.
1923 In order to let the testing shell script know which algorithms
1924 are available, a new (up to now undocumented) command
1925 "openssl list-cipher-commands" is used.
1926 [Bodo Moeller]
1927
1928 *) Bugfix: s_client occasionally would sleep in select() when
1929 it should have checked SSL_pending() first.
1930 [Bodo Moeller]
1931
1932 *) New functions DSA_do_sign and DSA_do_verify to provide access to
1933 the raw DSA values prior to ASN.1 encoding.
1934 [Ulf Möller]
1935
1936 *) Tweaks to Configure
1937 [Niels Poppe <niels@netbox.org>]
1938
1939 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
1940 yet...
1941 [Steve Henson]
1942
1943 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
1944 [Ulf Möller]
1945
1946 *) New config option to avoid instructions that are illegal on the 80386.
1947 The default code is faster, but requires at least a 486.
1948 [Ulf Möller]
1949
1950 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
1951 SSL2_SERVER_VERSION (not used at all) macros, which are now the
1952 same as SSL2_VERSION anyway.
1953 [Bodo Moeller]
1954
1955 *) New "-showcerts" option for s_client.
1956 [Bodo Moeller]
1957
1958 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
1959 application. Various cleanups and fixes.
1960 [Steve Henson]
1961
1962 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
1963 modify error routines to work internally. Add error codes and PBE init
1964 to library startup routines.
1965 [Steve Henson]
1966
1967 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
1968 packing functions to asn1 and evp. Changed function names and error
1969 codes along the way.
1970 [Steve Henson]
1971
1972 *) PKCS12 integration: and so it begins... First of several patches to
1973 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
1974 objects to objects.h
1975 [Steve Henson]
1976
1977 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
1978 and display support for Thawte strong extranet extension.
1979 [Steve Henson]
1980
1981 *) Add LinuxPPC support.
1982 [Jeff Dubrule <igor@pobox.org>]
1983
1984 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
1985 bn_div_words in alpha.s.
1986 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
1987
1988 *) Make sure the RSA OAEP test is skipped under -DRSAref because
1989 OAEP isn't supported when OpenSSL is built with RSAref.
1990 [Ulf Moeller <ulf@fitug.de>]
1991
1992 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
1993 so they no longer are missing under -DNOPROTO.
1994 [Soren S. Jorvang <soren@t.dk>]
1995
1996
1997 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
1998
1999 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
2000 doesn't work when the session is reused. Coming soon!
2001 [Ben Laurie]
2002
2003 *) Fix a security hole, that allows sessions to be reused in the wrong
2004 context thus bypassing client cert protection! All software that uses
2005 client certs and session caches in multiple contexts NEEDS PATCHING to
2006 allow session reuse! A fuller solution is in the works.
2007 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
2008
2009 *) Some more source tree cleanups (removed obsolete files
2010 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
2011 permission on "config" script to be executable) and a fix for the INSTALL
2012 document.
2013 [Ulf Moeller <ulf@fitug.de>]
2014
2015 *) Remove some legacy and erroneous uses of malloc, free instead of
2016 Malloc, Free.
2017 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
2018
2019 *) Make rsa_oaep_test return non-zero on error.
2020 [Ulf Moeller <ulf@fitug.de>]
2021
2022 *) Add support for native Solaris shared libraries. Configure
2023 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
2024 if someone would make that last step automatic.
2025 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
2026
2027 *) ctx_size was not built with the right compiler during "make links". Fixed.
2028 [Ben Laurie]
2029
2030 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
2031 except NULL ciphers". This means the default cipher list will no longer
2032 enable NULL ciphers. They need to be specifically enabled e.g. with
2033 the string "DEFAULT:eNULL".
2034 [Steve Henson]
2035
2036 *) Fix to RSA private encryption routines: if p < q then it would
2037 occasionally produce an invalid result. This will only happen with
2038 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
2039 [Steve Henson]
2040
2041 *) Be less restrictive and allow also `perl util/perlpath.pl
2042 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
2043 because this way one can also use an interpreter named `perl5' (which is
2044 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
2045 installed as `perl').
2046 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2047
2048 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
2049 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2050
2051 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
2052 advapi32.lib to Win32 build and change the pem test comparision
2053 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
2054 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
2055 and crypto/des/ede_cbcm_enc.c.
2056 [Steve Henson]
2057
2058 *) DES quad checksum was broken on big-endian architectures. Fixed.
2059 [Ben Laurie]
2060
2061 *) Comment out two functions in bio.h that aren't implemented. Fix up the
2062 Win32 test batch file so it (might) work again. The Win32 test batch file
2063 is horrible: I feel ill....
2064 [Steve Henson]
2065
2066 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
2067 in e_os.h. Audit of header files to check ANSI and non ANSI
2068 sections: 10 functions were absent from non ANSI section and not exported
2069 from Windows DLLs. Fixed up libeay.num for new functions.
2070 [Steve Henson]
2071
2072 *) Make `openssl version' output lines consistent.
2073 [Ralf S. Engelschall]
2074
2075 *) Fix Win32 symbol export lists for BIO functions: Added
2076 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
2077 to ms/libeay{16,32}.def.
2078 [Ralf S. Engelschall]
2079
2080 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
2081 fine under Unix and passes some trivial tests I've now added. But the
2082 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
2083 added to make sure no one expects that this stuff really works in the
2084 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
2085 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
2086 openssl_bio.xs.
2087 [Ralf S. Engelschall]
2088
2089 *) Fix the generation of two part addresses in perl.
2090 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
2091
2092 *) Add config entry for Linux on MIPS.
2093 [John Tobey <jtobey@channel1.com>]
2094
2095 *) Make links whenever Configure is run, unless we are on Windoze.
2096 [Ben Laurie]
2097
2098 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
2099 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
2100 in CRLs.
2101 [Steve Henson]
2102
2103 *) Add a useful kludge to allow package maintainers to specify compiler and
2104 other platforms details on the command line without having to patch the
2105 Configure script everytime: One now can use ``perl Configure
2106 <id>:<details>'', i.e. platform ids are allowed to have details appended
2107 to them (seperated by colons). This is treated as there would be a static
2108 pre-configured entry in Configure's %table under key <id> with value
2109 <details> and ``perl Configure <id>'' is called. So, when you want to
2110 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
2111 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
2112 now, which overrides the FreeBSD-elf entry on-the-fly.
2113 [Ralf S. Engelschall]
2114
2115 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
2116 [Ben Laurie]
2117
2118 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
2119 on the `perl Configure ...' command line. This way one can compile
2120 OpenSSL libraries with Position Independent Code (PIC) which is needed
2121 for linking it into DSOs.
2122 [Ralf S. Engelschall]
2123
2124 *) Remarkably, export ciphers were totally broken and no-one had noticed!
2125 Fixed.
2126 [Ben Laurie]
2127
2128 *) Cleaned up the LICENSE document: The official contact for any license
2129 questions now is the OpenSSL core team under openssl-core@openssl.org.
2130 And add a paragraph about the dual-license situation to make sure people
2131 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
2132 to the OpenSSL toolkit.
2133 [Ralf S. Engelschall]
2134
2135 *) General source tree makefile cleanups: Made `making xxx in yyy...'
2136 display consistent in the source tree and replaced `/bin/rm' by `rm'.
2137 Additonally cleaned up the `make links' target: Remove unnecessary
2138 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
2139 to speed processing and no longer clutter the display with confusing
2140 stuff. Instead only the actually done links are displayed.
2141 [Ralf S. Engelschall]
2142
2143 *) Permit null encryption ciphersuites, used for authentication only. It used
2144 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
2145 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
2146 encryption.
2147 [Ben Laurie]
2148
2149 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
2150 signed attributes when verifying signatures (this would break them),
2151 the detached data encoding was wrong and public keys obtained using
2152 X509_get_pubkey() weren't freed.
2153 [Steve Henson]
2154
2155 *) Add text documentation for the BUFFER functions. Also added a work around
2156 to a Win95 console bug. This was triggered by the password read stuff: the
2157 last character typed gets carried over to the next fread(). If you were
2158 generating a new cert request using 'req' for example then the last
2159 character of the passphrase would be CR which would then enter the first
2160 field as blank.
2161 [Steve Henson]
2162
2163 *) Added the new `Includes OpenSSL Cryptography Software' button as
2164 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
2165 button and can be used by applications based on OpenSSL to show the
2166 relationship to the OpenSSL project.
2167 [Ralf S. Engelschall]
2168
2169 *) Remove confusing variables in function signatures in files
2170 ssl/ssl_lib.c and ssl/ssl.h.
2171 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2172
2173 *) Don't install bss_file.c under PREFIX/include/
2174 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2175
2176 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
2177 functions that return function pointers and has support for NT specific
2178 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
2179 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
2180 unsigned to signed types: this was killing the Win32 compile.
2181 [Steve Henson]
2182
2183 *) Add new certificate file to stack functions,
2184 SSL_add_dir_cert_subjects_to_stack() and
2185 SSL_add_file_cert_subjects_to_stack(). These largely supplant
2186 SSL_load_client_CA_file(), and can be used to add multiple certs easily
2187 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
2188 This means that Apache-SSL and similar packages don't have to mess around
2189 to add as many CAs as they want to the preferred list.
2190 [Ben Laurie]
2191
2192 *) Experiment with doxygen documentation. Currently only partially applied to
2193 ssl/ssl_lib.c.
2194 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
2195 openssl.doxy as the configuration file.
2196 [Ben Laurie]
2197
2198 *) Get rid of remaining C++-style comments which strict C compilers hate.
2199 [Ralf S. Engelschall, pointed out by Carlos Amengual]
2200
2201 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
2202 compiled in by default: it has problems with large keys.
2203 [Steve Henson]
2204
2205 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
2206 DH private keys and/or callback functions which directly correspond to
2207 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
2208 is needed for applications which have to configure certificates on a
2209 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
2210 (e.g. s_server).
2211 For the RSA certificate situation is makes no difference, but
2212 for the DSA certificate situation this fixes the "no shared cipher"
2213 problem where the OpenSSL cipher selection procedure failed because the
2214 temporary keys were not overtaken from the context and the API provided
2215 no way to reconfigure them.
2216 The new functions now let applications reconfigure the stuff and they
2217 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
2218 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
2219 non-public-API function ssl_cert_instantiate() is used as a helper
2220 function and also to reduce code redundancy inside ssl_rsa.c.
2221 [Ralf S. Engelschall]
2222
2223 *) Move s_server -dcert and -dkey options out of the undocumented feature
2224 area because they are useful for the DSA situation and should be
2225 recognized by the users.
2226 [Ralf S. Engelschall]
2227
2228 *) Fix the cipher decision scheme for export ciphers: the export bits are
2229 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
2230 SSL_EXP_MASK. So, the original variable has to be used instead of the
2231 already masked variable.
2232 [Richard Levitte <levitte@stacken.kth.se>]
2233
2234 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
2235 [Richard Levitte <levitte@stacken.kth.se>]
2236
2237 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
2238 from `int' to `unsigned int' because it's a length and initialized by
2239 EVP_DigestFinal() which expects an `unsigned int *'.
2240 [Richard Levitte <levitte@stacken.kth.se>]
2241
2242 *) Don't hard-code path to Perl interpreter on shebang line of Configure
2243 script. Instead use the usual Shell->Perl transition trick.
2244 [Ralf S. Engelschall]
2245
2246 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
2247 (in addition to RSA certificates) to match the behaviour of `openssl dsa
2248 -noout -modulus' as it's already the case for `openssl rsa -noout
2249 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
2250 currently the public key is printed (a decision which was already done by
2251 `openssl dsa -modulus' in the past) which serves a similar purpose.
2252 Additionally the NO_RSA no longer completely removes the whole -modulus
2253 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
2254 now, too.
2255 [Ralf S. Engelschall]
2256
2257 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
2258 BIO. See the source (crypto/evp/bio_ok.c) for more info.
2259 [Arne Ansper <arne@ats.cyber.ee>]
2260
2261 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
2262 to be added. Now both 'req' and 'ca' can use new objects defined in the
2263 config file.
2264 [Steve Henson]
2265
2266 *) Add cool BIO that does syslog (or event log on NT).
2267 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
2268
2269 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
2270 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
2271 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
2272 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
2273 [Ben Laurie]
2274
2275 *) Add preliminary config info for new extension code.
2276 [Steve Henson]
2277
2278 *) Make RSA_NO_PADDING really use no padding.
2279 [Ulf Moeller <ulf@fitug.de>]
2280
2281 *) Generate errors when private/public key check is done.
2282 [Ben Laurie]
2283
2284 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
2285 for some CRL extensions and new objects added.
2286 [Steve Henson]
2287
2288 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
2289 key usage extension and fuller support for authority key id.
2290 [Steve Henson]
2291
2292 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
2293 padding method for RSA, which is recommended for new applications in PKCS
2294 #1 v2.0 (RFC 2437, October 1998).
2295 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
2296 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
2297 against Bleichbacher's attack on RSA.
2298 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
2299 Ben Laurie]
2300
2301 *) Updates to the new SSL compression code
2302 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2303
2304 *) Fix so that the version number in the master secret, when passed
2305 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
2306 (because the server will not accept higher), that the version number
2307 is 0x03,0x01, not 0x03,0x00
2308 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2309
2310 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
2311 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
2312 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
2313 [Steve Henson]
2314
2315 *) Support for RAW extensions where an arbitrary extension can be
2316 created by including its DER encoding. See apps/openssl.cnf for
2317 an example.
2318 [Steve Henson]
2319
2320 *) Make sure latest Perl versions don't interpret some generated C array
2321 code as Perl array code in the crypto/err/err_genc.pl script.
2322 [Lars Weber <3weber@informatik.uni-hamburg.de>]
2323
2324 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
2325 not many people have the assembler. Various Win32 compilation fixes and
2326 update to the INSTALL.W32 file with (hopefully) more accurate Win32
2327 build instructions.
2328 [Steve Henson]
2329
2330 *) Modify configure script 'Configure' to automatically create crypto/date.h
2331 file under Win32 and also build pem.h from pem.org. New script
2332 util/mkfiles.pl to create the MINFO file on environments that can't do a
2333 'make files': perl util/mkfiles.pl >MINFO should work.
2334 [Steve Henson]
2335
2336 *) Major rework of DES function declarations, in the pursuit of correctness
2337 and purity. As a result, many evil casts evaporated, and some weirdness,
2338 too. You may find this causes warnings in your code. Zapping your evil
2339 casts will probably fix them. Mostly.
2340 [Ben Laurie]
2341
2342 *) Fix for a typo in asn1.h. Bug fix to object creation script
2343 obj_dat.pl. It considered a zero in an object definition to mean
2344 "end of object": none of the objects in objects.h have any zeros
2345 so it wasn't spotted.
2346 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
2347
2348 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
2349 Masking (CBCM). In the absence of test vectors, the best I have been able
2350 to do is check that the decrypt undoes the encrypt, so far. Send me test
2351 vectors if you have them.
2352 [Ben Laurie]
2353
2354 *) Correct calculation of key length for export ciphers (too much space was
2355 allocated for null ciphers). This has not been tested!
2356 [Ben Laurie]
2357
2358 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
2359 message is now correct (it understands "crypto" and "ssl" on its
2360 command line). There is also now an "update" option. This will update
2361 the util/ssleay.num and util/libeay.num files with any new functions.
2362 If you do a:
2363 perl util/mkdef.pl crypto ssl update
2364 it will update them.
2365 [Steve Henson]
2366
2367 *) Overhauled the Perl interface (perl/*):
2368 - ported BN stuff to OpenSSL's different BN library
2369 - made the perl/ source tree CVS-aware
2370 - renamed the package from SSLeay to OpenSSL (the files still contain
2371 their history because I've copied them in the repository)
2372 - removed obsolete files (the test scripts will be replaced
2373 by better Test::Harness variants in the future)
2374 [Ralf S. Engelschall]
2375
2376 *) First cut for a very conservative source tree cleanup:
2377 1. merge various obsolete readme texts into doc/ssleay.txt
2378 where we collect the old documents and readme texts.
2379 2. remove the first part of files where I'm already sure that we no
2380 longer need them because of three reasons: either they are just temporary
2381 files which were left by Eric or they are preserved original files where
2382 I've verified that the diff is also available in the CVS via "cvs diff
2383 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
2384 the crypto/md/ stuff).
2385 [Ralf S. Engelschall]
2386
2387 *) More extension code. Incomplete support for subject and issuer alt
2388 name, issuer and authority key id. Change the i2v function parameters
2389 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
2390 what that's for :-) Fix to ASN1 macro which messed up
2391 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
2392 [Steve Henson]
2393
2394 *) Preliminary support for ENUMERATED type. This is largely copied from the
2395 INTEGER code.
2396 [Steve Henson]
2397
2398 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
2399 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2400
2401 *) Make sure `make rehash' target really finds the `openssl' program.
2402 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2403
2404 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
2405 like to hear about it if this slows down other processors.
2406 [Ben Laurie]
2407
2408 *) Add CygWin32 platform information to Configure script.
2409 [Alan Batie <batie@aahz.jf.intel.com>]
2410
2411 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
2412 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
2413
2414 *) New program nseq to manipulate netscape certificate sequences
2415 [Steve Henson]
2416
2417 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
2418 few typos.
2419 [Steve Henson]
2420
2421 *) Fixes to BN code. Previously the default was to define BN_RECURSION
2422 but the BN code had some problems that would cause failures when
2423 doing certificate verification and some other functions.
2424 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2425
2426 *) Add ASN1 and PEM code to support netscape certificate sequences.
2427 [Steve Henson]
2428
2429 *) Add ASN1 and PEM code to support netscape certificate sequences.
2430 [Steve Henson]
2431
2432 *) Add several PKIX and private extended key usage OIDs.
2433 [Steve Henson]
2434
2435 *) Modify the 'ca' program to handle the new extension code. Modify
2436 openssl.cnf for new extension format, add comments.
2437 [Steve Henson]
2438
2439 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
2440 and add a sample to openssl.cnf so req -x509 now adds appropriate
2441 CA extensions.
2442 [Steve Henson]
2443
2444 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
2445 error code, add initial support to X509_print() and x509 application.
2446 [Steve Henson]
2447
2448 *) Takes a deep breath and start addding X509 V3 extension support code. Add
2449 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
2450 stuff is currently isolated and isn't even compiled yet.
2451 [Steve Henson]
2452
2453 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
2454 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
2455 Removed the versions check from X509 routines when loading extensions:
2456 this allows certain broken certificates that don't set the version
2457 properly to be processed.
2458 [Steve Henson]
2459
2460 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
2461 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
2462 can still be regenerated with "make depend".
2463 [Ben Laurie]
2464
2465 *) Spelling mistake in C version of CAST-128.
2466 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
2467
2468 *) Changes to the error generation code. The perl script err-code.pl
2469 now reads in the old error codes and retains the old numbers, only
2470 adding new ones if necessary. It also only changes the .err files if new
2471 codes are added. The makefiles have been modified to only insert errors
2472 when needed (to avoid needlessly modifying header files). This is done
2473 by only inserting errors if the .err file is newer than the auto generated
2474 C file. To rebuild all the error codes from scratch (the old behaviour)
2475 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
2476 or delete all the .err files.
2477 [Steve Henson]
2478
2479 *) CAST-128 was incorrectly implemented for short keys. The C version has
2480 been fixed, but is untested. The assembler versions are also fixed, but
2481 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
2482 to regenerate it if needed.
2483 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
2484 Hagino <itojun@kame.net>]
2485
2486 *) File was opened incorrectly in randfile.c.
2487 [Ulf Möller <ulf@fitug.de>]
2488
2489 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
2490 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
2491 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
2492 al: it's just almost always a UTCTime. Note this patch adds new error
2493 codes so do a "make errors" if there are problems.
2494 [Steve Henson]
2495
2496 *) Correct Linux 1 recognition in config.
2497 [Ulf Möller <ulf@fitug.de>]
2498
2499 *) Remove pointless MD5 hash when using DSA keys in ca.
2500 [Anonymous <nobody@replay.com>]
2501
2502 *) Generate an error if given an empty string as a cert directory. Also
2503 generate an error if handed NULL (previously returned 0 to indicate an
2504 error, but didn't set one).
2505 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
2506
2507 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
2508 [Ben Laurie]
2509
2510 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
2511 parameters. This was causing a warning which killed off the Win32 compile.
2512 [Steve Henson]
2513
2514 *) Remove C++ style comments from crypto/bn/bn_local.h.
2515 [Neil Costigan <neil.costigan@celocom.com>]
2516
2517 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
2518 based on a text string, looking up short and long names and finally
2519 "dot" format. The "dot" format stuff didn't work. Added new function
2520 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
2521 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
2522 OID is not part of the table.
2523 [Steve Henson]
2524
2525 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
2526 X509_LOOKUP_by_alias().
2527 [Ben Laurie]
2528
2529 *) Sort openssl functions by name.
2530 [Ben Laurie]
2531
2532 *) Get the gendsa program working (hopefully) and add it to app list. Remove
2533 encryption from sample DSA keys (in case anyone is interested the password
2534 was "1234").
2535 [Steve Henson]
2536
2537 *) Make _all_ *_free functions accept a NULL pointer.
2538 [Frans Heymans <fheymans@isaserver.be>]
2539
2540 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
2541 NULL pointers.
2542 [Anonymous <nobody@replay.com>]
2543
2544 *) s_server should send the CAfile as acceptable CAs, not its own cert.
2545 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2546
2547 *) Don't blow it for numeric -newkey arguments to apps/req.
2548 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2549
2550 *) Temp key "for export" tests were wrong in s3_srvr.c.
2551 [Anonymous <nobody@replay.com>]
2552
2553 *) Add prototype for temp key callback functions
2554 SSL_CTX_set_tmp_{rsa,dh}_callback().
2555 [Ben Laurie]
2556
2557 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
2558 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
2559 [Steve Henson]
2560
2561 *) X509_name_add_entry() freed the wrong thing after an error.
2562 [Arne Ansper <arne@ats.cyber.ee>]
2563
2564 *) rsa_eay.c would attempt to free a NULL context.
2565 [Arne Ansper <arne@ats.cyber.ee>]
2566
2567 *) BIO_s_socket() had a broken should_retry() on Windoze.
2568 [Arne Ansper <arne@ats.cyber.ee>]
2569
2570 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
2571 [Arne Ansper <arne@ats.cyber.ee>]
2572
2573 *) Make sure the already existing X509_STORE->depth variable is initialized
2574 in X509_STORE_new(), but document the fact that this variable is still
2575 unused in the certificate verification process.
2576 [Ralf S. Engelschall]
2577
2578 *) Fix the various library and apps files to free up pkeys obtained from
2579 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
2580 [Steve Henson]
2581
2582 *) Fix reference counting in X509_PUBKEY_get(). This makes
2583 demos/maurice/example2.c work, amongst others, probably.
2584 [Steve Henson and Ben Laurie]
2585
2586 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
2587 `openssl' and second, the shortcut symlinks for the `openssl <command>'
2588 are no longer created. This way we have a single and consistent command
2589 line interface `openssl <command>', similar to `cvs <command>'.
2590 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
2591
2592 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
2593 BIT STRING wrapper always have zero unused bits.
2594 [Steve Henson]
2595
2596 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
2597 [Steve Henson]
2598
2599 *) Make the top-level INSTALL documentation easier to understand.
2600 [Paul Sutton]
2601
2602 *) Makefiles updated to exit if an error occurs in a sub-directory
2603 make (including if user presses ^C) [Paul Sutton]
2604
2605 *) Make Montgomery context stuff explicit in RSA data structure.
2606 [Ben Laurie]
2607
2608 *) Fix build order of pem and err to allow for generated pem.h.
2609 [Ben Laurie]
2610
2611 *) Fix renumbering bug in X509_NAME_delete_entry().
2612 [Ben Laurie]
2613
2614 *) Enhanced the err-ins.pl script so it makes the error library number
2615 global and can add a library name. This is needed for external ASN1 and
2616 other error libraries.
2617 [Steve Henson]
2618
2619 *) Fixed sk_insert which never worked properly.
2620 [Steve Henson]
2621
2622 *) Fix ASN1 macros so they can handle indefinite length construted
2623 EXPLICIT tags. Some non standard certificates use these: they can now
2624 be read in.
2625 [Steve Henson]
2626
2627 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
2628 into a single doc/ssleay.txt bundle. This way the information is still
2629 preserved but no longer messes up this directory. Now it's new room for
2630 the new set of documenation files.
2631 [Ralf S. Engelschall]
2632
2633 *) SETs were incorrectly DER encoded. This was a major pain, because they
2634 shared code with SEQUENCEs, which aren't coded the same. This means that
2635 almost everything to do with SETs or SEQUENCEs has either changed name or
2636 number of arguments.
2637 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
2638
2639 *) Fix test data to work with the above.
2640 [Ben Laurie]
2641
2642 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
2643 was already fixed by Eric for 0.9.1 it seems.
2644 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
2645
2646 *) Autodetect FreeBSD3.
2647 [Ben Laurie]
2648
2649 *) Fix various bugs in Configure. This affects the following platforms:
2650 nextstep
2651 ncr-scde
2652 unixware-2.0
2653 unixware-2.0-pentium
2654 sco5-cc.
2655 [Ben Laurie]
2656
2657 *) Eliminate generated files from CVS. Reorder tests to regenerate files
2658 before they are needed.
2659 [Ben Laurie]
2660
2661 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
2662 [Ben Laurie]
2663
2664
2665 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
2666
2667 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
2668 changed SSLeay to OpenSSL in version strings.
2669 [Ralf S. Engelschall]
2670
2671 *) Some fixups to the top-level documents.
2672 [Paul Sutton]
2673
2674 *) Fixed the nasty bug where rsaref.h was not found under compile-time
2675 because the symlink to include/ was missing.
2676 [Ralf S. Engelschall]
2677
2678 *) Incorporated the popular no-RSA/DSA-only patches
2679 which allow to compile a RSA-free SSLeay.
2680 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
2681
2682 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
2683 when "ssleay" is still not found.
2684 [Ralf S. Engelschall]
2685
2686 *) Added more platforms to Configure: Cray T3E, HPUX 11,
2687 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
2688
2689 *) Updated the README file.
2690 [Ralf S. Engelschall]
2691
2692 *) Added various .cvsignore files in the CVS repository subdirs
2693 to make a "cvs update" really silent.
2694 [Ralf S. Engelschall]
2695
2696 *) Recompiled the error-definition header files and added
2697 missing symbols to the Win32 linker tables.
2698 [Ralf S. Engelschall]
2699
2700 *) Cleaned up the top-level documents;
2701 o new files: CHANGES and LICENSE
2702 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
2703 o merged COPYRIGHT into LICENSE
2704 o removed obsolete TODO file
2705 o renamed MICROSOFT to INSTALL.W32
2706 [Ralf S. Engelschall]
2707
2708 *) Removed dummy files from the 0.9.1b source tree:
2709 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
2710 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
2711 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
2712 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
2713 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
2714 [Ralf S. Engelschall]
2715
2716 *) Added various platform portability fixes.
2717 [Mark J. Cox]
2718
2719 *) The Genesis of the OpenSSL rpject:
2720 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
2721 Young and Tim J. Hudson created while they were working for C2Net until
2722 summer 1998.
2723 [The OpenSSL Project]
2724
2725
2726 Changes between 0.9.0b and 0.9.1b [not released]
2727
2728 *) Updated a few CA certificates under certs/
2729 [Eric A. Young]
2730
2731 *) Changed some BIGNUM api stuff.
2732 [Eric A. Young]
2733
2734 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
2735 DGUX x86, Linux Alpha, etc.
2736 [Eric A. Young]
2737
2738 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
2739 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
2740 available).
2741 [Eric A. Young]
2742
2743 *) Add -strparse option to asn1pars program which parses nested
2744 binary structures
2745 [Dr Stephen Henson <shenson@bigfoot.com>]
2746
2747 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
2748 [Eric A. Young]
2749
2750 *) DSA fix for "ca" program.
2751 [Eric A. Young]
2752
2753 *) Added "-genkey" option to "dsaparam" program.
2754 [Eric A. Young]
2755
2756 *) Added RIPE MD160 (rmd160) message digest.
2757 [Eric A. Young]
2758
2759 *) Added -a (all) option to "ssleay version" command.
2760 [Eric A. Young]
2761
2762 *) Added PLATFORM define which is the id given to Configure.
2763 [Eric A. Young]
2764
2765 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
2766 [Eric A. Young]
2767
2768 *) Extended the ASN.1 parser routines.
2769 [Eric A. Young]
2770
2771 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
2772 [Eric A. Young]
2773
2774 *) Added a BN_CTX to the BN library.
2775 [Eric A. Young]
2776
2777 *) Fixed the weak key values in DES library
2778 [Eric A. Young]
2779
2780 *) Changed API in EVP library for cipher aliases.
2781 [Eric A. Young]
2782
2783 *) Added support for RC2/64bit cipher.
2784 [Eric A. Young]
2785
2786 *) Converted the lhash library to the crypto/mem.c functions.
2787 [Eric A. Young]
2788
2789 *) Added more recognized ASN.1 object ids.
2790 [Eric A. Young]
2791
2792 *) Added more RSA padding checks for SSL/TLS.
2793 [Eric A. Young]
2794
2795 *) Added BIO proxy/filter functionality.
2796 [Eric A. Young]
2797
2798 *) Added extra_certs to SSL_CTX which can be used
2799 send extra CA certificates to the client in the CA cert chain sending
2800 process. It can be configured with SSL_CTX_add_extra_chain_cert().
2801 [Eric A. Young]
2802
2803 *) Now Fortezza is denied in the authentication phase because
2804 this is key exchange mechanism is not supported by SSLeay at all.
2805 [Eric A. Young]
2806
2807 *) Additional PKCS1 checks.
2808 [Eric A. Young]
2809
2810 *) Support the string "TLSv1" for all TLS v1 ciphers.
2811 [Eric A. Young]
2812
2813 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
2814 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
2815 [Eric A. Young]
2816
2817 *) Fixed a few memory leaks.
2818 [Eric A. Young]
2819
2820 *) Fixed various code and comment typos.
2821 [Eric A. Young]
2822
2823 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
2824 bytes sent in the client random.
2825 [Edward Bishop <ebishop@spyglass.com>]
2826
