3 _______________
4
5 Changes between 0.9.3a and 0.9.4
6
7 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
8 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
9 problems not only on Windows, but also on some Unix platforms.
10 To avoid problematic command lines, these definitions are now made
11 in auto-generated file crypto/buildinf.h, which also defines DATE
12 and thus replaces crypto/date.h.
13 [Bodo Moeller]
14
15 *) MIPS III/IV assembler module is reimplemented.
16 [Andy Polyakov]
17
18 *) More DES library cleanups: remove references to srand/rand and
19 delete an unused file.
20 [Ulf Möller]
21
22 *) Add support for the the free Netwide assembler (NASM) under Win32,
23 since not many people have MASM (ml) and it can be hard to obtain.
24 This is currently experimental but it seems to work OK and pass all
25 the tests. Check out INSTALL.W32 for info.
26 [Steve Henson]
27
28 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
29 without temporary keys kept an extra copy of the server key,
30 and connections with temporary keys did not free everything in case
31 of an error.
32 [Bodo Moeller]
33
34 *) New function RSA_check_key and new openssl rsa option -check
35 for verifying the consistency of RSA keys.
36 [Ulf Moeller, Bodo Moeller]
37
38 *) Various changes to make Win32 compile work:
39 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
40 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
41 comparison" warnings.
42 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
43 [Steve Henson]
44
45 *) Add a debugging option to PKCS#5 v2 key generation function: when
46 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
47 derived keys are printed to stderr.
48 [Steve Henson]
49
50 *) Copy the flags in ASN1_STRING_dup().
51 [Roman E. Pavlov <pre@mo.msk.ru>]
52
53 *) The x509 application mishandled signing requests containing DSA
54 keys when the signing key was also DSA and the parameters didn't match.
55
56 It was supposed to omit the parameters when they matched the signing key:
57 the verifying software was then supposed to automatically use the CA's
58 parameters if they were absent from the end user certificate.
59
60 Omitting parameters is no longer recommended. The test was also
61 the wrong way round! This was probably due to unusual behaviour in
62 EVP_cmp_parameters() which returns 1 if the parameters match.
63 This meant that parameters were omitted when they *didn't* match and
64 the certificate was useless. Certificates signed with 'ca' didn't have
65 this bug.
66 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
67
68 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
69 The interface is as follows:
70 Applications can use
71 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
72 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
73 "off" is now the default.
74 The library internally uses
75 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
76 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
77 to disable memory-checking temporarily.
78
79 Some inconsistent states that previously were possible (and were
80 even the default) are now avoided.
81
82 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
83 with each memory chunk allocated; this is occasionally more helpful
84 than just having a counter.
85
86 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
87
88 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
89 extensions.
90 [Bodo Moeller]
91
92 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
93 which largely parallels "options", but is for changing API behaviour,
94 whereas "options" are about protocol behaviour.
95 Initial "mode" flags are:
96
97 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
98 a single record has been written.
99 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
100 retries use the same buffer location.
101 (But all of the contents must be
102 copied!)
103 [Bodo Moeller]
104
105 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
106 worked.
107
108 *) Fix problems with no-hmac etc.
109 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
110
111 *) New functions RSA_get_default_method(), RSA_set_method() and
112 RSA_get_method(). These allows replacement of RSA_METHODs without having
113 to mess around with the internals of an RSA structure.
114 [Steve Henson]
115
116 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
117 Also really enable memory leak checks in openssl.c and in some
118 test programs.
119 [Chad C. Mulligan, Bodo Moeller]
120
121 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
122 up the length of negative integers. This has now been simplified to just
123 store the length when it is first determined and use it later, rather
124 than trying to keep track of where data is copied and updating it to
125 point to the end.
126 [Steve Henson, reported by Brien Wheeler
127 <bwheeler@authentica-security.com>]
128
129 *) Add a new function PKCS7_signatureVerify. This allows the verification
130 of a PKCS#7 signature but with the signing certificate passed to the
131 function itself. This contrasts with PKCS7_dataVerify which assumes the
132 certificate is present in the PKCS#7 structure. This isn't always the
133 case: certificates can be omitted from a PKCS#7 structure and be
134 distributed by "out of band" means (such as a certificate database).
135 [Steve Henson]
136
137 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
138 function prototypes in pem.h, also change util/mkdef.pl to add the
139 necessary function names.
140 [Steve Henson]
141
142 *) mk1mf.pl (used by Windows builds) did not properly read the
143 options set by Configure in the top level Makefile, and Configure
144 was not even able to write more than one option correctly.
145 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
146 [Bodo Moeller]
147
148 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
149 file to be loaded from a BIO or FILE pointer. The BIO version will
150 for example allow memory BIOs to contain config info.
151 [Steve Henson]
152
153 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
154 Whoever hopes to achieve shared-library compatibility across versions
155 must use this, not the compile-time macro.
156 (Exercise 0.9.4: Which is the minimum library version required by
157 such programs?)
158 Note: All this applies only to multi-threaded programs, others don't
159 need locks.
160 [Bodo Moeller]
161
162 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
163 through a BIO pair triggered the default case, i.e.
164 SSLerr(...,SSL_R_UNKNOWN_STATE).
165 [Bodo Moeller]
166
167 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
168 can use the SSL library even if none of the specific BIOs is
169 appropriate.
170 [Bodo Moeller]
171
172 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
173 for the encoded length.
174 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
175
176 *) Add initial documentation of the X509V3 functions.
177 [Steve Henson]
178
179 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
180 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
181 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
182 secure PKCS#8 private key format with a high iteration count.
183 [Steve Henson]
184
185 *) Fix determination of Perl interpreter: A perl or perl5
186 _directory_ in $PATH was also accepted as the interpreter.
187 [Ralf S. Engelschall]
188
189 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
190 wrong with it but it was very old and did things like calling
191 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
192 unusual formatting.
193 [Steve Henson]
194
195 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
196 to use the new extension code.
197 [Steve Henson]
198
199 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
200 with macros. This should make it easier to change their form, add extra
201 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
202 constant.
203 [Steve Henson]
204
205 *) Add to configuration table a new entry that can specify an alternative
206 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
207 according to Mark Crispin <MRC@Panda.COM>.
208 [Bodo Moeller]
209
210 #if 0
211 *) DES CBC did not update the IV. Weird.
212 [Ben Laurie]
213 #else
214 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
215 Changing the behaviour of the former might break existing programs --
216 where IV updating is needed, des_ncbc_encrypt can be used.
217 #endif
218
219 *) When bntest is run from "make test" it drives bc to check its
220 calculations, as well as internally checking them. If an internal check
221 fails, it needs to cause bc to give a non-zero result or make test carries
222 on without noticing the failure. Fixed.
223 [Ben Laurie]
224
225 *) DES library cleanups.
226 [Ulf Möller]
227
228 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
229 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
230 ciphers. NOTE: although the key derivation function has been verified
231 against some published test vectors it has not been extensively tested
232 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
233 of v2.0.
234 [Steve Henson]
235
236 *) Instead of "mkdir -p", which is not fully portable, use new
237 Perl script "util/mkdir-p.pl".
238 [Bodo Moeller]
239
240 *) Rewrite the way password based encryption (PBE) is handled. It used to
241 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
242 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
243 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
244 the 'parameter' field of the AlgorithmIdentifier is passed to the
245 underlying key generation function so it must do its own ASN1 parsing.
246 This has also changed the EVP_PBE_CipherInit() function which now has a
247 'parameter' argument instead of literal salt and iteration count values
248 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
249 [Steve Henson]
250
251 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
252 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
253 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
254 KEY" because this clashed with PKCS#8 unencrypted string. Since this
255 value was just used as a "magic string" and not used directly its
256 value doesn't matter.
257 [Steve Henson]
258
259 *) Introduce some semblance of const correctness to BN. Shame C doesn't
260 support mutable.
261 [Ben Laurie]
262
263 *) "linux-sparc64" configuration (ultrapenguin).
264 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
265 "linux-sparc" configuration.
266 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
267
268 *) config now generates no-xxx options for missing ciphers.
269 [Ulf Möller]
270
271 *) Support the EBCDIC character set (work in progress).
272 File ebcdic.c not yet included because it has a different license.
273 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
274
275 *) Support BS2000/OSD-POSIX.
276 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
277
278 *) Make callbacks for key generation use void * instead of char *.
279 [Ben Laurie]
280
281 *) Make S/MIME samples compile (not yet tested).
282 [Ben Laurie]
283
284 *) Additional typesafe stacks.
285 [Ben Laurie]
286
287 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
288 [Bodo Moeller]
289
290
291 Changes between 0.9.3 and 0.9.3a [29 May 1999]
292
293 *) New configuration variant "sco5-gcc".
294
295 *) Updated some demos.
296 [Sean O Riordain, Wade Scholine]
297
298 *) Add missing BIO_free at exit of pkcs12 application.
299 [Wu Zhigang]
300
301 *) Fix memory leak in conf.c.
302 [Steve Henson]
303
304 *) Updates for Win32 to assembler version of MD5.
305 [Steve Henson]
306
307 *) Set #! path to perl in apps/der_chop to where we found it
308 instead of using a fixed path.
309 [Bodo Moeller]
310
311 *) SHA library changes for irix64-mips4-cc.
312 [Andy Polyakov]
313
314 *) Improvements for VMS support.
315 [Richard Levitte]
316
317
318 Changes between 0.9.2b and 0.9.3 [24 May 1999]
319
320 *) Bignum library bug fix. IRIX 6 passes "make test" now!
321 This also avoids the problems with SC4.2 and unpatched SC5.
322 [Andy Polyakov <appro@fy.chalmers.se>]
323
324 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
325 These are required because of the typesafe stack would otherwise break
326 existing code. If old code used a structure member which used to be STACK
327 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
328 sk_num or sk_value it would produce an error because the num, data members
329 are not present in STACK_OF. Now it just produces a warning. sk_set
330 replaces the old method of assigning a value to sk_value
331 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
332 that does this will no longer work (and should use sk_set instead) but
333 this could be regarded as a "questionable" behaviour anyway.
334 [Steve Henson]
335
336 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
337 correctly handle encrypted S/MIME data.
338 [Steve Henson]
339
340 *) Change type of various DES function arguments from des_cblock
341 (which means, in function argument declarations, pointer to char)
342 to des_cblock * (meaning pointer to array with 8 char elements),
343 which allows the compiler to do more typechecking; it was like
344 that back in SSLeay, but with lots of ugly casts.
345
346 Introduce new type const_des_cblock.
347 [Bodo Moeller]
348
349 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
350 problems: find RecipientInfo structure that matches recipient certificate
351 and initialise the ASN1 structures properly based on passed cipher.
352 [Steve Henson]
353
354 *) Belatedly make the BN tests actually check the results.
355 [Ben Laurie]
356
357 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
358 to and from BNs: it was completely broken. New compilation option
359 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
360 key elements as negative integers.
361 [Steve Henson]
362
363 *) Reorganize and speed up MD5.
364 [Andy Polyakov <appro@fy.chalmers.se>]
365
366 *) VMS support.
367 [Richard Levitte <richard@levitte.org>]
368
369 *) New option -out to asn1parse to allow the parsed structure to be
370 output to a file. This is most useful when combined with the -strparse
371 option to examine the output of things like OCTET STRINGS.
372 [Steve Henson]
373
374 *) Make SSL library a little more fool-proof by not requiring any longer
375 that SSL_set_{accept,connect}_state be called before
376 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
377 in many applications because usually everything *appeared* to work as
378 intended anyway -- now it really works as intended).
379 [Bodo Moeller]
380
381 *) Move openssl.cnf out of lib/.
382 [Ulf Möller]
383
384 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
385 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
386 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
387 [Ralf S. Engelschall]
388
389 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
390 handle PKCS#7 enveloped data properly.
391 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
392
393 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
394 copying pointers. The cert_st handling is changed by this in
395 various ways (and thus what used to be known as ctx->default_cert
396 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
397 any longer when s->cert does not give us what we need).
398 ssl_cert_instantiate becomes obsolete by this change.
399 As soon as we've got the new code right (possibly it already is?),
400 we have solved a couple of bugs of the earlier code where s->cert
401 was used as if it could not have been shared with other SSL structures.
402
403 Note that using the SSL API in certain dirty ways now will result
404 in different behaviour than observed with earlier library versions:
405 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
406 does not influence s as it used to.
407
408 In order to clean up things more thoroughly, inside SSL_SESSION
409 we don't use CERT any longer, but a new structure SESS_CERT
410 that holds per-session data (if available); currently, this is
411 the peer's certificate chain and, for clients, the server's certificate
412 and temporary key. CERT holds only those values that can have
413 meaningful defaults in an SSL_CTX.
414 [Bodo Moeller]
415
416 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
417 from the internal representation. Various PKCS#7 fixes: remove some
418 evil casts and set the enc_dig_alg field properly based on the signing
419 key type.
420 [Steve Henson]
421
422 *) Allow PKCS#12 password to be set from the command line or the
423 environment. Let 'ca' get its config file name from the environment
424 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
425 and 'x509').
426 [Steve Henson]
427
428 *) Allow certificate policies extension to use an IA5STRING for the
429 organization field. This is contrary to the PKIX definition but
430 VeriSign uses it and IE5 only recognises this form. Document 'x509'
431 extension option.
432 [Steve Henson]
433
434 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
435 without disallowing inline assembler and the like for non-pedantic builds.
436 [Ben Laurie]
437
438 *) Support Borland C++ builder.
439 [Janez Jere <jj@void.si>, modified by Ulf Möller]
440
441 *) Support Mingw32.
442 [Ulf Möller]
443
444 *) SHA-1 cleanups and performance enhancements.
445 [Andy Polyakov <appro@fy.chalmers.se>]
446
447 *) Sparc v8plus assembler for the bignum library.
448 [Andy Polyakov <appro@fy.chalmers.se>]
449
450 *) Accept any -xxx and +xxx compiler options in Configure.
451 [Ulf Möller]
452
453 *) Update HPUX configuration.
454 [Anonymous]
455
456 *) Add missing sk_<type>_unshift() function to safestack.h
457 [Ralf S. Engelschall]
458
459 *) New function SSL_CTX_use_certificate_chain_file that sets the
460 "extra_cert"s in addition to the certificate. (This makes sense
461 only for "PEM" format files, as chains as a whole are not
462 DER-encoded.)
463 [Bodo Moeller]
464
465 *) Support verify_depth from the SSL API.
466 x509_vfy.c had what can be considered an off-by-one-error:
467 Its depth (which was not part of the external interface)
468 was actually counting the number of certificates in a chain;
469 now it really counts the depth.
470 [Bodo Moeller]
471
472 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
473 instead of X509err, which often resulted in confusing error
474 messages since the error codes are not globally unique
475 (e.g. an alleged error in ssl3_accept when a certificate
476 didn't match the private key).
477
478 *) New function SSL_CTX_set_session_id_context that allows to set a default
479 value (so that you don't need SSL_set_session_id_context for each
480 connection using the SSL_CTX).
481 [Bodo Moeller]
482
483 *) OAEP decoding bug fix.
484 [Ulf Möller]
485
486 *) Support INSTALL_PREFIX for package builders, as proposed by
487 David Harris.
488 [Bodo Moeller]
489
490 *) New Configure options "threads" and "no-threads". For systems
491 where the proper compiler options are known (currently Solaris
492 and Linux), "threads" is the default.
493 [Bodo Moeller]
494
495 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
496 [Bodo Moeller]
497
498 *) Install various scripts to $(OPENSSLDIR)/misc, not to
499 $(INSTALLTOP)/bin -- they shouldn't clutter directories
500 such as /usr/local/bin.
501 [Bodo Moeller]
502
503 *) "make linux-shared" to build shared libraries.
504 [Niels Poppe <niels@netbox.org>]
505
506 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
507 [Ulf Möller]
508
509 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
510 extension adding in x509 utility.
511 [Steve Henson]
512
513 *) Remove NOPROTO sections and error code comments.
514 [Ulf Möller]
515
516 *) Partial rewrite of the DEF file generator to now parse the ANSI
517 prototypes.
518 [Steve Henson]
519
520 *) New Configure options --prefix=DIR and --openssldir=DIR.
521 [Ulf Möller]
522
523 *) Complete rewrite of the error code script(s). It is all now handled
524 by one script at the top level which handles error code gathering,
525 header rewriting and C source file generation. It should be much better
526 than the old method: it now uses a modified version of Ulf's parser to
527 read the ANSI prototypes in all header files (thus the old K&R definitions
528 aren't needed for error creation any more) and do a better job of
529 translating function codes into names. The old 'ASN1 error code imbedded
530 in a comment' is no longer necessary and it doesn't use .err files which
531 have now been deleted. Also the error code call doesn't have to appear all
532 on one line (which resulted in some large lines...).
533 [Steve Henson]
534
535 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
536 [Bodo Moeller]
537
538 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
539 0 (which usually indicates a closed connection), but continue reading.
540 [Bodo Moeller]
541
542 *) Fix some race conditions.
543 [Bodo Moeller]
544
545 *) Add support for CRL distribution points extension. Add Certificate
546 Policies and CRL distribution points documentation.
547 [Steve Henson]
548
549 *) Move the autogenerated header file parts to crypto/opensslconf.h.
550 [Ulf Möller]
551
552 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
553 8 of keying material. Merlin has also confirmed interop with this fix
554 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
555 [Merlin Hughes <merlin@baltimore.ie>]
556
557 *) Fix lots of warnings.
558 [Richard Levitte <levitte@stacken.kth.se>]
559
560 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
561 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
562 [Richard Levitte <levitte@stacken.kth.se>]
563
564 *) Fix problems with sizeof(long) == 8.
565 [Andy Polyakov <appro@fy.chalmers.se>]
566
567 *) Change functions to ANSI C.
568 [Ulf Möller]
569
570 *) Fix typos in error codes.
571 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
572
573 *) Remove defunct assembler files from Configure.
574 [Ulf Möller]
575
576 *) SPARC v8 assembler BIGNUM implementation.
577 [Andy Polyakov <appro@fy.chalmers.se>]
578
579 *) Support for Certificate Policies extension: both print and set.
580 Various additions to support the r2i method this uses.
581 [Steve Henson]
582
583 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
584 return a const string when you are expecting an allocated buffer.
585 [Ben Laurie]
586
587 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
588 types DirectoryString and DisplayText.
589 [Steve Henson]
590
591 *) Add code to allow r2i extensions to access the configuration database,
592 add an LHASH database driver and add several ctx helper functions.
593 [Steve Henson]
594
595 *) Fix an evil bug in bn_expand2() which caused various BN functions to
596 fail when they extended the size of a BIGNUM.
597 [Steve Henson]
598
599 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
600 support typesafe stack.
601 [Steve Henson]
602
603 *) Fix typo in SSL_[gs]et_options().
604 [Nils Frostberg <nils@medcom.se>]
605
606 *) Delete various functions and files that belonged to the (now obsolete)
607 old X509V3 handling code.
608 [Steve Henson]
609
610 *) New Configure option "rsaref".
611 [Ulf Möller]
612
613 *) Don't auto-generate pem.h.
614 [Bodo Moeller]
615
616 *) Introduce type-safe ASN.1 SETs.
617 [Ben Laurie]
618
619 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
620 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
621
622 *) Introduce type-safe STACKs. This will almost certainly break lots of code
623 that links with OpenSSL (well at least cause lots of warnings), but fear
624 not: the conversion is trivial, and it eliminates loads of evil casts. A
625 few STACKed things have been converted already. Feel free to convert more.
626 In the fullness of time, I'll do away with the STACK type altogether.
627 [Ben Laurie]
628
629 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
630 specified in <certfile> by updating the entry in the index.txt file.
631 This way one no longer has to edit the index.txt file manually for
632 revoking a certificate. The -revoke option does the gory details now.
633 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
634
635 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
636 `-text' option at all and this way the `-noout -text' combination was
637 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
638 [Ralf S. Engelschall]
639
640 *) Make sure a corresponding plain text error message exists for the
641 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
642 verify callback function determined that a certificate was revoked.
643 [Ralf S. Engelschall]
644
645 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
646 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
647 all available cipers including rc5, which was forgotten until now.
648 In order to let the testing shell script know which algorithms
649 are available, a new (up to now undocumented) command
650 "openssl list-cipher-commands" is used.
651 [Bodo Moeller]
652
653 *) Bugfix: s_client occasionally would sleep in select() when
654 it should have checked SSL_pending() first.
655 [Bodo Moeller]
656
657 *) New functions DSA_do_sign and DSA_do_verify to provide access to
658 the raw DSA values prior to ASN.1 encoding.
659 [Ulf Möller]
660
661 *) Tweaks to Configure
662 [Niels Poppe <niels@netbox.org>]
663
664 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
665 yet...
666 [Steve Henson]
667
668 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
669 [Ulf Möller]
670
671 *) New config option to avoid instructions that are illegal on the 80386.
672 The default code is faster, but requires at least a 486.
673 [Ulf Möller]
674
675 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
676 SSL2_SERVER_VERSION (not used at all) macros, which are now the
677 same as SSL2_VERSION anyway.
678 [Bodo Moeller]
679
680 *) New "-showcerts" option for s_client.
681 [Bodo Moeller]
682
683 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
684 application. Various cleanups and fixes.
685 [Steve Henson]
686
687 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
688 modify error routines to work internally. Add error codes and PBE init
689 to library startup routines.
690 [Steve Henson]
691
692 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
693 packing functions to asn1 and evp. Changed function names and error
694 codes along the way.
695 [Steve Henson]
696
697 *) PKCS12 integration: and so it begins... First of several patches to
698 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
699 objects to objects.h
700 [Steve Henson]
701
702 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
703 and display support for Thawte strong extranet extension.
704 [Steve Henson]
705
706 *) Add LinuxPPC support.
707 [Jeff Dubrule <igor@pobox.org>]
708
709 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
710 bn_div_words in alpha.s.
711 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
712
713 *) Make sure the RSA OAEP test is skipped under -DRSAref because
714 OAEP isn't supported when OpenSSL is built with RSAref.
715 [Ulf Moeller <ulf@fitug.de>]
716
717 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
718 so they no longer are missing under -DNOPROTO.
719 [Soren S. Jorvang <soren@t.dk>]
720
721
722 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
723
724 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
725 doesn't work when the session is reused. Coming soon!
726 [Ben Laurie]
727
728 *) Fix a security hole, that allows sessions to be reused in the wrong
729 context thus bypassing client cert protection! All software that uses
730 client certs and session caches in multiple contexts NEEDS PATCHING to
731 allow session reuse! A fuller solution is in the works.
732 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
733
734 *) Some more source tree cleanups (removed obsolete files
735 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
736 permission on "config" script to be executable) and a fix for the INSTALL
737 document.
738 [Ulf Moeller <ulf@fitug.de>]
739
740 *) Remove some legacy and erroneous uses of malloc, free instead of
741 Malloc, Free.
742 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
743
744 *) Make rsa_oaep_test return non-zero on error.
745 [Ulf Moeller <ulf@fitug.de>]
746
747 *) Add support for native Solaris shared libraries. Configure
748 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
749 if someone would make that last step automatic.
750 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
751
752 *) ctx_size was not built with the right compiler during "make links". Fixed.
753 [Ben Laurie]
754
755 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
756 except NULL ciphers". This means the default cipher list will no longer
757 enable NULL ciphers. They need to be specifically enabled e.g. with
758 the string "DEFAULT:eNULL".
759 [Steve Henson]
760
761 *) Fix to RSA private encryption routines: if p < q then it would
762 occasionally produce an invalid result. This will only happen with
763 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
764 [Steve Henson]
765
766 *) Be less restrictive and allow also `perl util/perlpath.pl
767 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
768 because this way one can also use an interpreter named `perl5' (which is
769 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
770 installed as `perl').
771 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
772
773 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
774 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
775
776 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
777 advapi32.lib to Win32 build and change the pem test comparision
778 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
779 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
780 and crypto/des/ede_cbcm_enc.c.
781 [Steve Henson]
782
783 *) DES quad checksum was broken on big-endian architectures. Fixed.
784 [Ben Laurie]
785
786 *) Comment out two functions in bio.h that aren't implemented. Fix up the
787 Win32 test batch file so it (might) work again. The Win32 test batch file
788 is horrible: I feel ill....
789 [Steve Henson]
790
791 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
792 in e_os.h. Audit of header files to check ANSI and non ANSI
793 sections: 10 functions were absent from non ANSI section and not exported
794 from Windows DLLs. Fixed up libeay.num for new functions.
795 [Steve Henson]
796
797 *) Make `openssl version' output lines consistent.
798 [Ralf S. Engelschall]
799
800 *) Fix Win32 symbol export lists for BIO functions: Added
801 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
802 to ms/libeay{16,32}.def.
803 [Ralf S. Engelschall]
804
805 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
806 fine under Unix and passes some trivial tests I've now added. But the
807 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
808 added to make sure no one expects that this stuff really works in the
809 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
810 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
811 openssl_bio.xs.
812 [Ralf S. Engelschall]
813
814 *) Fix the generation of two part addresses in perl.
815 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
816
817 *) Add config entry for Linux on MIPS.
818 [John Tobey <jtobey@channel1.com>]
819
820 *) Make links whenever Configure is run, unless we are on Windoze.
821 [Ben Laurie]
822
823 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
824 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
825 in CRLs.
826 [Steve Henson]
827
828 *) Add a useful kludge to allow package maintainers to specify compiler and
829 other platforms details on the command line without having to patch the
830 Configure script everytime: One now can use ``perl Configure
831 <id>:<details>'', i.e. platform ids are allowed to have details appended
832 to them (seperated by colons). This is treated as there would be a static
833 pre-configured entry in Configure's %table under key <id> with value
834 <details> and ``perl Configure <id>'' is called. So, when you want to
835 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
836 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
837 now, which overrides the FreeBSD-elf entry on-the-fly.
838 [Ralf S. Engelschall]
839
840 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
841 [Ben Laurie]
842
843 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
844 on the `perl Configure ...' command line. This way one can compile
845 OpenSSL libraries with Position Independent Code (PIC) which is needed
846 for linking it into DSOs.
847 [Ralf S. Engelschall]
848
849 *) Remarkably, export ciphers were totally broken and no-one had noticed!
850 Fixed.
851 [Ben Laurie]
852
853 *) Cleaned up the LICENSE document: The official contact for any license
854 questions now is the OpenSSL core team under openssl-core@openssl.org.
855 And add a paragraph about the dual-license situation to make sure people
856 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
857 to the OpenSSL toolkit.
858 [Ralf S. Engelschall]
859
860 *) General source tree makefile cleanups: Made `making xxx in yyy...'
861 display consistent in the source tree and replaced `/bin/rm' by `rm'.
862 Additonally cleaned up the `make links' target: Remove unnecessary
863 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
864 to speed processing and no longer clutter the display with confusing
865 stuff. Instead only the actually done links are displayed.
866 [Ralf S. Engelschall]
867
868 *) Permit null encryption ciphersuites, used for authentication only. It used
869 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
870 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
871 encryption.
872 [Ben Laurie]
873
874 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
875 signed attributes when verifying signatures (this would break them),
876 the detached data encoding was wrong and public keys obtained using
877 X509_get_pubkey() weren't freed.
878 [Steve Henson]
879
880 *) Add text documentation for the BUFFER functions. Also added a work around
881 to a Win95 console bug. This was triggered by the password read stuff: the
882 last character typed gets carried over to the next fread(). If you were
883 generating a new cert request using 'req' for example then the last
884 character of the passphrase would be CR which would then enter the first
885 field as blank.
886 [Steve Henson]
887
888 *) Added the new `Includes OpenSSL Cryptography Software' button as
889 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
890 button and can be used by applications based on OpenSSL to show the
891 relationship to the OpenSSL project.
892 [Ralf S. Engelschall]
893
894 *) Remove confusing variables in function signatures in files
895 ssl/ssl_lib.c and ssl/ssl.h.
896 [Lennart Bong <lob@kulthea.stacken.kth.se>]
897
898 *) Don't install bss_file.c under PREFIX/include/
899 [Lennart Bong <lob@kulthea.stacken.kth.se>]
900
901 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
902 functions that return function pointers and has support for NT specific
903 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
904 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
905 unsigned to signed types: this was killing the Win32 compile.
906 [Steve Henson]
907
908 *) Add new certificate file to stack functions,
909 SSL_add_dir_cert_subjects_to_stack() and
910 SSL_add_file_cert_subjects_to_stack(). These largely supplant
911 SSL_load_client_CA_file(), and can be used to add multiple certs easily
912 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
913 This means that Apache-SSL and similar packages don't have to mess around
914 to add as many CAs as they want to the preferred list.
915 [Ben Laurie]
916
917 *) Experiment with doxygen documentation. Currently only partially applied to
918 ssl/ssl_lib.c.
919 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
920 openssl.doxy as the configuration file.
921 [Ben Laurie]
922
923 *) Get rid of remaining C++-style comments which strict C compilers hate.
924 [Ralf S. Engelschall, pointed out by Carlos Amengual]
925
926 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
927 compiled in by default: it has problems with large keys.
928 [Steve Henson]
929
930 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
931 DH private keys and/or callback functions which directly correspond to
932 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
933 is needed for applications which have to configure certificates on a
934 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
935 (e.g. s_server).
936 For the RSA certificate situation is makes no difference, but
937 for the DSA certificate situation this fixes the "no shared cipher"
938 problem where the OpenSSL cipher selection procedure failed because the
939 temporary keys were not overtaken from the context and the API provided
940 no way to reconfigure them.
941 The new functions now let applications reconfigure the stuff and they
942 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
943 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
944 non-public-API function ssl_cert_instantiate() is used as a helper
945 function and also to reduce code redundancy inside ssl_rsa.c.
946 [Ralf S. Engelschall]
947
948 *) Move s_server -dcert and -dkey options out of the undocumented feature
949 area because they are useful for the DSA situation and should be
950 recognized by the users.
951 [Ralf S. Engelschall]
952
953 *) Fix the cipher decision scheme for export ciphers: the export bits are
954 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
955 SSL_EXP_MASK. So, the original variable has to be used instead of the
956 already masked variable.
957 [Richard Levitte <levitte@stacken.kth.se>]
958
959 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
960 [Richard Levitte <levitte@stacken.kth.se>]
961
962 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
963 from `int' to `unsigned int' because it's a length and initialized by
964 EVP_DigestFinal() which expects an `unsigned int *'.
965 [Richard Levitte <levitte@stacken.kth.se>]
966
967 *) Don't hard-code path to Perl interpreter on shebang line of Configure
968 script. Instead use the usual Shell->Perl transition trick.
969 [Ralf S. Engelschall]
970
971 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
972 (in addition to RSA certificates) to match the behaviour of `openssl dsa
973 -noout -modulus' as it's already the case for `openssl rsa -noout
974 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
975 currently the public key is printed (a decision which was already done by
976 `openssl dsa -modulus' in the past) which serves a similar purpose.
977 Additionally the NO_RSA no longer completely removes the whole -modulus
978 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
979 now, too.
980 [Ralf S. Engelschall]
981
982 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
983 BIO. See the source (crypto/evp/bio_ok.c) for more info.
984 [Arne Ansper <arne@ats.cyber.ee>]
985
986 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
987 to be added. Now both 'req' and 'ca' can use new objects defined in the
988 config file.
989 [Steve Henson]
990
991 *) Add cool BIO that does syslog (or event log on NT).
992 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
993
994 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
995 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
996 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
997 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
998 [Ben Laurie]
999
1000 *) Add preliminary config info for new extension code.
1001 [Steve Henson]
1002
1003 *) Make RSA_NO_PADDING really use no padding.
1004 [Ulf Moeller <ulf@fitug.de>]
1005
1006 *) Generate errors when private/public key check is done.
1007 [Ben Laurie]
1008
1009 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1010 for some CRL extensions and new objects added.
1011 [Steve Henson]
1012
1013 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1014 key usage extension and fuller support for authority key id.
1015 [Steve Henson]
1016
1017 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1018 padding method for RSA, which is recommended for new applications in PKCS
1019 #1 v2.0 (RFC 2437, October 1998).
1020 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1021 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1022 against Bleichbacher's attack on RSA.
1023 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1024 Ben Laurie]
1025
1026 *) Updates to the new SSL compression code
1027 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1028
1029 *) Fix so that the version number in the master secret, when passed
1030 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1031 (because the server will not accept higher), that the version number
1032 is 0x03,0x01, not 0x03,0x00
1033 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1034
1035 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1036 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1037 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1038 [Steve Henson]
1039
1040 *) Support for RAW extensions where an arbitrary extension can be
1041 created by including its DER encoding. See apps/openssl.cnf for
1042 an example.
1043 [Steve Henson]
1044
1045 *) Make sure latest Perl versions don't interpret some generated C array
1046 code as Perl array code in the crypto/err/err_genc.pl script.
1047 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1048
1049 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1050 not many people have the assembler. Various Win32 compilation fixes and
1051 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1052 build instructions.
1053 [Steve Henson]
1054
1055 *) Modify configure script 'Configure' to automatically create crypto/date.h
1056 file under Win32 and also build pem.h from pem.org. New script
1057 util/mkfiles.pl to create the MINFO file on environments that can't do a
1058 'make files': perl util/mkfiles.pl >MINFO should work.
1059 [Steve Henson]
1060
1061 *) Major rework of DES function declarations, in the pursuit of correctness
1062 and purity. As a result, many evil casts evaporated, and some weirdness,
1063 too. You may find this causes warnings in your code. Zapping your evil
1064 casts will probably fix them. Mostly.
1065 [Ben Laurie]
1066
1067 *) Fix for a typo in asn1.h. Bug fix to object creation script
1068 obj_dat.pl. It considered a zero in an object definition to mean
1069 "end of object": none of the objects in objects.h have any zeros
1070 so it wasn't spotted.
1071 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1072
1073 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1074 Masking (CBCM). In the absence of test vectors, the best I have been able
1075 to do is check that the decrypt undoes the encrypt, so far. Send me test
1076 vectors if you have them.
1077 [Ben Laurie]
1078
1079 *) Correct calculation of key length for export ciphers (too much space was
1080 allocated for null ciphers). This has not been tested!
1081 [Ben Laurie]
1082
1083 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1084 message is now correct (it understands "crypto" and "ssl" on its
1085 command line). There is also now an "update" option. This will update
1086 the util/ssleay.num and util/libeay.num files with any new functions.
1087 If you do a:
1088 perl util/mkdef.pl crypto ssl update
1089 it will update them.
1090 [Steve Henson]
1091
1092 *) Overhauled the Perl interface (perl/*):
1093 - ported BN stuff to OpenSSL's different BN library
1094 - made the perl/ source tree CVS-aware
1095 - renamed the package from SSLeay to OpenSSL (the files still contain
1096 their history because I've copied them in the repository)
1097 - removed obsolete files (the test scripts will be replaced
1098 by better Test::Harness variants in the future)
1099 [Ralf S. Engelschall]
1100
1101 *) First cut for a very conservative source tree cleanup:
1102 1. merge various obsolete readme texts into doc/ssleay.txt
1103 where we collect the old documents and readme texts.
1104 2. remove the first part of files where I'm already sure that we no
1105 longer need them because of three reasons: either they are just temporary
1106 files which were left by Eric or they are preserved original files where
1107 I've verified that the diff is also available in the CVS via "cvs diff
1108 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1109 the crypto/md/ stuff).
1110 [Ralf S. Engelschall]
1111
1112 *) More extension code. Incomplete support for subject and issuer alt
1113 name, issuer and authority key id. Change the i2v function parameters
1114 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1115 what that's for :-) Fix to ASN1 macro which messed up
1116 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1117 [Steve Henson]
1118
1119 *) Preliminary support for ENUMERATED type. This is largely copied from the
1120 INTEGER code.
1121 [Steve Henson]
1122
1123 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1124 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1125
1126 *) Make sure `make rehash' target really finds the `openssl' program.
1127 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1128
1129 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1130 like to hear about it if this slows down other processors.
1131 [Ben Laurie]
1132
1133 *) Add CygWin32 platform information to Configure script.
1134 [Alan Batie <batie@aahz.jf.intel.com>]
1135
1136 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1137 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1138
1139 *) New program nseq to manipulate netscape certificate sequences
1140 [Steve Henson]
1141
1142 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1143 few typos.
1144 [Steve Henson]
1145
1146 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1147 but the BN code had some problems that would cause failures when
1148 doing certificate verification and some other functions.
1149 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1150
1151 *) Add ASN1 and PEM code to support netscape certificate sequences.
1152 [Steve Henson]
1153
1154 *) Add ASN1 and PEM code to support netscape certificate sequences.
1155 [Steve Henson]
1156
1157 *) Add several PKIX and private extended key usage OIDs.
1158 [Steve Henson]
1159
1160 *) Modify the 'ca' program to handle the new extension code. Modify
1161 openssl.cnf for new extension format, add comments.
1162 [Steve Henson]
1163
1164 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1165 and add a sample to openssl.cnf so req -x509 now adds appropriate
1166 CA extensions.
1167 [Steve Henson]
1168
1169 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1170 error code, add initial support to X509_print() and x509 application.
1171 [Steve Henson]
1172
1173 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1174 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1175 stuff is currently isolated and isn't even compiled yet.
1176 [Steve Henson]
1177
1178 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1179 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1180 Removed the versions check from X509 routines when loading extensions:
1181 this allows certain broken certificates that don't set the version
1182 properly to be processed.
1183 [Steve Henson]
1184
1185 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1186 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1187 can still be regenerated with "make depend".
1188 [Ben Laurie]
1189
1190 *) Spelling mistake in C version of CAST-128.
1191 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1192
1193 *) Changes to the error generation code. The perl script err-code.pl
1194 now reads in the old error codes and retains the old numbers, only
1195 adding new ones if necessary. It also only changes the .err files if new
1196 codes are added. The makefiles have been modified to only insert errors
1197 when needed (to avoid needlessly modifying header files). This is done
1198 by only inserting errors if the .err file is newer than the auto generated
1199 C file. To rebuild all the error codes from scratch (the old behaviour)
1200 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1201 or delete all the .err files.
1202 [Steve Henson]
1203
1204 *) CAST-128 was incorrectly implemented for short keys. The C version has
1205 been fixed, but is untested. The assembler versions are also fixed, but
1206 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1207 to regenerate it if needed.
1208 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1209 Hagino <itojun@kame.net>]
1210
1211 *) File was opened incorrectly in randfile.c.
1212 [Ulf Möller <ulf@fitug.de>]
1213
1214 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1215 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1216 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1217 al: it's just almost always a UTCTime. Note this patch adds new error
1218 codes so do a "make errors" if there are problems.
1219 [Steve Henson]
1220
1221 *) Correct Linux 1 recognition in config.
1222 [Ulf Möller <ulf@fitug.de>]
1223
1224 *) Remove pointless MD5 hash when using DSA keys in ca.
1225 [Anonymous <nobody@replay.com>]
1226
1227 *) Generate an error if given an empty string as a cert directory. Also
1228 generate an error if handed NULL (previously returned 0 to indicate an
1229 error, but didn't set one).
1230 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1231
1232 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1233 [Ben Laurie]
1234
1235 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1236 parameters. This was causing a warning which killed off the Win32 compile.
1237 [Steve Henson]
1238
1239 *) Remove C++ style comments from crypto/bn/bn_local.h.
1240 [Neil Costigan <neil.costigan@celocom.com>]
1241
1242 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1243 based on a text string, looking up short and long names and finally
1244 "dot" format. The "dot" format stuff didn't work. Added new function
1245 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1246 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1247 OID is not part of the table.
1248 [Steve Henson]
1249
1250 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1251 X509_LOOKUP_by_alias().
1252 [Ben Laurie]
1253
1254 *) Sort openssl functions by name.
1255 [Ben Laurie]
1256
1257 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1258 encryption from sample DSA keys (in case anyone is interested the password
1259 was "1234").
1260 [Steve Henson]
1261
1262 *) Make _all_ *_free functions accept a NULL pointer.
1263 [Frans Heymans <fheymans@isaserver.be>]
1264
1265 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1266 NULL pointers.
1267 [Anonymous <nobody@replay.com>]
1268
1269 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1270 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1271
1272 *) Don't blow it for numeric -newkey arguments to apps/req.
1273 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1274
1275 *) Temp key "for export" tests were wrong in s3_srvr.c.
1276 [Anonymous <nobody@replay.com>]
1277
1278 *) Add prototype for temp key callback functions
1279 SSL_CTX_set_tmp_{rsa,dh}_callback().
1280 [Ben Laurie]
1281
1282 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1283 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1284 [Steve Henson]
1285
1286 *) X509_name_add_entry() freed the wrong thing after an error.
1287 [Arne Ansper <arne@ats.cyber.ee>]
1288
1289 *) rsa_eay.c would attempt to free a NULL context.
1290 [Arne Ansper <arne@ats.cyber.ee>]
1291
1292 *) BIO_s_socket() had a broken should_retry() on Windoze.
1293 [Arne Ansper <arne@ats.cyber.ee>]
1294
1295 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1296 [Arne Ansper <arne@ats.cyber.ee>]
1297
1298 *) Make sure the already existing X509_STORE->depth variable is initialized
1299 in X509_STORE_new(), but document the fact that this variable is still
1300 unused in the certificate verification process.
1301 [Ralf S. Engelschall]
1302
1303 *) Fix the various library and apps files to free up pkeys obtained from
1304 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1305 [Steve Henson]
1306
1307 *) Fix reference counting in X509_PUBKEY_get(). This makes
1308 demos/maurice/example2.c work, amongst others, probably.
1309 [Steve Henson and Ben Laurie]
1310
1311 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1312 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1313 are no longer created. This way we have a single and consistent command
1314 line interface `openssl <command>', similar to `cvs <command>'.
1315 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1316
1317 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1318 BIT STRING wrapper always have zero unused bits.
1319 [Steve Henson]
1320
1321 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1322 [Steve Henson]
1323
1324 *) Make the top-level INSTALL documentation easier to understand.
1325 [Paul Sutton]
1326
1327 *) Makefiles updated to exit if an error occurs in a sub-directory
1328 make (including if user presses ^C) [Paul Sutton]
1329
1330 *) Make Montgomery context stuff explicit in RSA data structure.
1331 [Ben Laurie]
1332
1333 *) Fix build order of pem and err to allow for generated pem.h.
1334 [Ben Laurie]
1335
1336 *) Fix renumbering bug in X509_NAME_delete_entry().
1337 [Ben Laurie]
1338
1339 *) Enhanced the err-ins.pl script so it makes the error library number
1340 global and can add a library name. This is needed for external ASN1 and
1341 other error libraries.
1342 [Steve Henson]
1343
1344 *) Fixed sk_insert which never worked properly.
1345 [Steve Henson]
1346
1347 *) Fix ASN1 macros so they can handle indefinite length construted
1348 EXPLICIT tags. Some non standard certificates use these: they can now
1349 be read in.
1350 [Steve Henson]
1351
1352 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1353 into a single doc/ssleay.txt bundle. This way the information is still
1354 preserved but no longer messes up this directory. Now it's new room for
1355 the new set of documenation files.
1356 [Ralf S. Engelschall]
1357
1358 *) SETs were incorrectly DER encoded. This was a major pain, because they
1359 shared code with SEQUENCEs, which aren't coded the same. This means that
1360 almost everything to do with SETs or SEQUENCEs has either changed name or
1361 number of arguments.
1362 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1363
1364 *) Fix test data to work with the above.
1365 [Ben Laurie]
1366
1367 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1368 was already fixed by Eric for 0.9.1 it seems.
1369 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1370
1371 *) Autodetect FreeBSD3.
1372 [Ben Laurie]
1373
1374 *) Fix various bugs in Configure. This affects the following platforms:
1375 nextstep
1376 ncr-scde
1377 unixware-2.0
1378 unixware-2.0-pentium
1379 sco5-cc.
1380 [Ben Laurie]
1381
1382 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1383 before they are needed.
1384 [Ben Laurie]
1385
1386 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1387 [Ben Laurie]
1388
1389
1390 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1391
1392 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1393 changed SSLeay to OpenSSL in version strings.
1394 [Ralf S. Engelschall]
1395
1396 *) Some fixups to the top-level documents.
1397 [Paul Sutton]
1398
1399 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1400 because the symlink to include/ was missing.
1401 [Ralf S. Engelschall]
1402
1403 *) Incorporated the popular no-RSA/DSA-only patches
1404 which allow to compile a RSA-free SSLeay.
1405 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1406
1407 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1408 when "ssleay" is still not found.
1409 [Ralf S. Engelschall]
1410
1411 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1412 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1413
1414 *) Updated the README file.
1415 [Ralf S. Engelschall]
1416
1417 *) Added various .cvsignore files in the CVS repository subdirs
1418 to make a "cvs update" really silent.
1419 [Ralf S. Engelschall]
1420
1421 *) Recompiled the error-definition header files and added
1422 missing symbols to the Win32 linker tables.
1423 [Ralf S. Engelschall]
1424
1425 *) Cleaned up the top-level documents;
1426 o new files: CHANGES and LICENSE
1427 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1428 o merged COPYRIGHT into LICENSE
1429 o removed obsolete TODO file
1430 o renamed MICROSOFT to INSTALL.W32
1431 [Ralf S. Engelschall]
1432
1433 *) Removed dummy files from the 0.9.1b source tree:
1434 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1435 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
1436 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
1437 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
1438 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1439 [Ralf S. Engelschall]
1440
1441 *) Added various platform portability fixes.
1442 [Mark J. Cox]
1443
1444 *) The Genesis of the OpenSSL rpject:
1445 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1446 Young and Tim J. Hudson created while they were working for C2Net until
1447 summer 1998.
1448 [The OpenSSL Project]
1449
1450
1451 Changes between 0.9.0b and 0.9.1b [not released]
1452
1453 *) Updated a few CA certificates under certs/
1454 [Eric A. Young]
1455
1456 *) Changed some BIGNUM api stuff.
1457 [Eric A. Young]
1458
1459 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1460 DGUX x86, Linux Alpha, etc.
1461 [Eric A. Young]
1462
1463 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1464 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1465 available).
1466 [Eric A. Young]
1467
1468 *) Add -strparse option to asn1pars program which parses nested
1469 binary structures
1470 [Dr Stephen Henson <shenson@bigfoot.com>]
1471
1472 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1473 [Eric A. Young]
1474
1475 *) DSA fix for "ca" program.
1476 [Eric A. Young]
1477
1478 *) Added "-genkey" option to "dsaparam" program.
1479 [Eric A. Young]
1480
1481 *) Added RIPE MD160 (rmd160) message digest.
1482 [Eric A. Young]
1483
1484 *) Added -a (all) option to "ssleay version" command.
1485 [Eric A. Young]
1486
1487 *) Added PLATFORM define which is the id given to Configure.
1488 [Eric A. Young]
1489
1490 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1491 [Eric A. Young]
1492
1493 *) Extended the ASN.1 parser routines.
1494 [Eric A. Young]
1495
1496 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1497 [Eric A. Young]
1498
1499 *) Added a BN_CTX to the BN library.
1500 [Eric A. Young]
1501
1502 *) Fixed the weak key values in DES library
1503 [Eric A. Young]
1504
1505 *) Changed API in EVP library for cipher aliases.
1506 [Eric A. Young]
1507
1508 *) Added support for RC2/64bit cipher.
1509 [Eric A. Young]
1510
1511 *) Converted the lhash library to the crypto/mem.c functions.
1512 [Eric A. Young]
1513
1514 *) Added more recognized ASN.1 object ids.
1515 [Eric A. Young]
1516
1517 *) Added more RSA padding checks for SSL/TLS.
1518 [Eric A. Young]
1519
1520 *) Added BIO proxy/filter functionality.
1521 [Eric A. Young]
1522
1523 *) Added extra_certs to SSL_CTX which can be used
1524 send extra CA certificates to the client in the CA cert chain sending
1525 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1526 [Eric A. Young]
