6 Changes between 0.9.2b and 0.9.3
7
8 *) New function SSL_CTX_set_session_id_context that allows to set a default
9 value (so that you don't need SSL_set_session_id_context for each connection
10 using the SSL_CTX).
11 [Bodo Moeller]
12
13 *) OAEP decoding bug fix.
14 [Ulf Möller]
15
16 *) Support INSTALL_PREFIX for package builders, as proposed by
17 David Harris.
18 [Bodo Moeller]
19
20 *) New Configure options "threads" and "no-threads". For systems
21 where the proper compiler options are known (currently Solaris
22 and Linux), "threads" is the default.
23 [Bodo Moeller]
24
25 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
26 [Bodo Moeller]
27
28 *) Install various scripts to $(OPENSSLDIR)/misc, not to
29 $(INSTALLTOP)/bin -- they shouldn't clutter directories
30 such as /usr/local/bin.
31 [Bodo Moeller]
32
33 *) "make linux-shared" to build shared libraries.
34 [Niels Poppe <niels@netbox.org>]
35
36 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
37 [Ulf Möller]
38
39 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
40 extension adding in x509 utility.
41 [Steve Henson]
42
43 *) Remove NOPROTO sections and error code comments.
44 [Ulf Möller]
45
46 *) Partial rewrite of the DEF file generator to now parse the ANSI
47 prototypes.
48 [Steve Henson]
49
50 *) New Configure options --prefix=DIR and --openssldir=DIR.
51 [Ulf Möller]
52
53 *) Complete rewrite of the error code script(s). It is all now handled
54 by one script at the top level which handles error code gathering,
55 header rewriting and C source file generation. It should be much better
56 than the old method: it now uses a modified version of Ulf's parser to
57 read the ANSI prototypes in all header files (thus the old K&R definitions
58 aren't needed for error creation any more) and do a better job of
59 translating function codes into names. The old 'ASN1 error code imbedded
60 in a comment' is no longer necessary and it doesn't use .err files which
61 have now been deleted. Also the error code call doesn't have to appear all
62 on one line (which resulted in some large lines...).
63 [Steve Henson]
64
65 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
66 [Bodo Moeller]
67
68 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
69 0 (which usually indicates a closed connection), but continue reading.
70 [Bodo Moeller]
71
72 *) Fix some race conditions.
73 [Bodo Moeller]
74
75 *) Add support for CRL distribution points extension. Add Certificate
76 Policies and CRL distribution points documentation.
77 [Steve Henson]
78
79 *) Move the autogenerated header file parts to crypto/opensslconf.h.
80 [Ulf Möller]
81
82 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
83 8 of keying material. Merlin has also confirmed interop with this fix
84 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
85 [Merlin Hughes <merlin@baltimore.ie>]
86
87 *) Fix lots of warnings.
88 [Richard Levitte <levitte@stacken.kth.se>]
89
90 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
91 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
92 [Richard Levitte <levitte@stacken.kth.se>]
93
94 *) Fix problems with sizeof(long) == 8.
95 [Andy Polyakov <appro@fy.chalmers.se>]
96
97 *) Change functions to ANSI C.
98 [Ulf Möller]
99
100 *) Fix typos in error codes.
101 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
102
103 *) Remove defunct assembler files from Configure.
104 [Ulf Möller]
105
106 *) SPARC v8 assembler BIGNUM implementation.
107 [Andy Polyakov <appro@fy.chalmers.se>]
108
109 *) Support for Certificate Policies extension: both print and set.
110 Various additions to support the r2i method this uses.
111 [Steve Henson]
112
113 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
114 return a const string when you are expecting an allocated buffer.
115 [Ben Laurie]
116
117 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
118 types DirectoryString and DisplayText.
119 [Steve Henson]
120
121 *) Add code to allow r2i extensions to access the configuration database,
122 add an LHASH database driver and add several ctx helper functions.
123 [Steve Henson]
124
125 *) Fix an evil bug in bn_expand2() which caused various BN functions to
126 fail when they extended the size of a BIGNUM.
127 [Steve Henson]
128
129 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
130 support typesafe stack.
131 [Steve Henson]
132
133 *) Fix typo in SSL_[gs]et_options().
134 [Nils Frostberg <nils@medcom.se>]
135
136 *) Delete various functions and files that belonged to the (now obsolete)
137 old X509V3 handling code.
138 [Steve Henson]
139
140 *) New Configure option "rsaref".
141 [Ulf Möller]
142
143 *) Don't auto-generate pem.h.
144 [Bodo Moeller]
145
146 *) Introduce type-safe ASN.1 SETs.
147 [Ben Laurie]
148
149 *) Introduce type-safe STACKs. This will almost certainly break lots of code
150 that links with OpenSSL (well at least cause lots of warnings), but fear
151 not: the conversion is trivial, and it eliminates loads of evil casts. A
152 few STACKed things have been converted already. Feel free to convert more.
153 In the fullness of time, I'll do away with the STACK type altogether.
154 [Ben Laurie]
155
156 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
157 specified in <certfile> by updating the entry in the index.txt file.
158 This way one no longer has to edit the index.txt file manually for
159 revoking a certificate. The -revoke option does the gory details now.
160 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
161
162 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
163 `-text' option at all and this way the `-noout -text' combination was
164 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
165 [Ralf S. Engelschall]
166
167 *) Make sure a corresponding plain text error message exists for the
168 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
169 verify callback function determined that a certificate was revoked.
170 [Ralf S. Engelschall]
171
172 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
173 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
174 all available cipers including rc5, which was forgotten until now.
175 In order to let the testing shell script know which algorithms
176 are available, a new (up to now undocumented) command
177 "openssl list-cipher-commands" is used.
178 [Bodo Moeller]
179
180 *) Bugfix: s_client occasionally would sleep in select() when
181 it should have checked SSL_pending() first.
182 [Bodo Moeller]
183
184 *) New functions DSA_do_sign and DSA_do_verify to provide access to
185 the raw DSA values prior to ASN.1 encoding.
186 [Ulf Möller]
187
188 *) Tweaks to Configure
189 Niels Poppe <niels@netbox.org>
190
191 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
192 yet...
193 [Steve Henson]
194
195 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
196 [Ulf Möller]
197
198 *) New config option to avoid instructions that are illegal on the 80386.
199 The default code is faster, but requires at least a 486.
200 [Ulf Möller]
201
202 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
203 SSL2_SERVER_VERSION (not used at all) macros, which are now the
204 same as SSL2_VERSION anyway.
205 [Bodo Moeller]
206
207 *) New "-showcerts" option for s_client.
208 [Bodo Moeller]
209
210 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
211 application. Various cleanups and fixes.
212 [Steve Henson]
213
214 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
215 modify error routines to work internally. Add error codes and PBE init
216 to library startup routines.
217 [Steve Henson]
218
219 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
220 packing functions to asn1 and evp. Changed function names and error
221 codes along the way.
222 [Steve Henson]
223
224 *) PKCS12 integration: and so it begins... First of several patches to
225 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
226 objects to objects.h
227 [Steve Henson]
228
229 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
230 and display support for Thawte strong extranet extension.
231 [Steve Henson]
232
233 *) Add LinuxPPC support.
234 [Jeff Dubrule <igor@pobox.org>]
235
236 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
237 bn_div_words in alpha.s.
238 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
239
240 *) Make sure the RSA OAEP test is skipped under -DRSAref because
241 OAEP isn't supported when OpenSSL is built with RSAref.
242 [Ulf Moeller <ulf@fitug.de>]
243
244 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
245 so they no longer are missing under -DNOPROTO.
246 [Soren S. Jorvang <soren@t.dk>]
247
248 Changes between 0.9.1c and 0.9.2b
249
250 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
251 doesn't work when the session is reused. Coming soon!
252 [Ben Laurie]
253
254 *) Fix a security hole, that allows sessions to be reused in the wrong
255 context thus bypassing client cert protection! All software that uses
256 client certs and session caches in multiple contexts NEEDS PATCHING to
257 allow session reuse! A fuller solution is in the works.
258 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
259
260 *) Some more source tree cleanups (removed obsolete files
261 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
262 permission on "config" script to be executable) and a fix for the INSTALL
263 document.
264 [Ulf Moeller <ulf@fitug.de>]
265
266 *) Remove some legacy and erroneous uses of malloc, free instead of
267 Malloc, Free.
268 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
269
270 *) Make rsa_oaep_test return non-zero on error.
271 [Ulf Moeller <ulf@fitug.de>]
272
273 *) Add support for native Solaris shared libraries. Configure
274 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
275 if someone would make that last step automatic.
276 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
277
278 *) ctx_size was not built with the right compiler during "make links". Fixed.
279 [Ben Laurie]
280
281 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
282 except NULL ciphers". This means the default cipher list will no longer
283 enable NULL ciphers. They need to be specifically enabled e.g. with
284 the string "DEFAULT:eNULL".
285 [Steve Henson]
286
287 *) Fix to RSA private encryption routines: if p < q then it would
288 occasionally produce an invalid result. This will only happen with
289 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
290 [Steve Henson]
291
292 *) Be less restrictive and allow also `perl util/perlpath.pl
293 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
294 because this way one can also use an interpreter named `perl5' (which is
295 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
296 installed as `perl').
297 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
298
299 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
300 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
301
302 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
303 advapi32.lib to Win32 build and change the pem test comparision
304 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
305 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
306 and crypto/des/ede_cbcm_enc.c.
307 [Steve Henson]
308
309 *) DES quad checksum was broken on big-endian architectures. Fixed.
310 [Ben Laurie]
311
312 *) Comment out two functions in bio.h that aren't implemented. Fix up the
313 Win32 test batch file so it (might) work again. The Win32 test batch file
314 is horrible: I feel ill....
315 [Steve Henson]
316
317 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
318 in e_os.h. Audit of header files to check ANSI and non ANSI
319 sections: 10 functions were absent from non ANSI section and not exported
320 from Windows DLLs. Fixed up libeay.num for new functions.
321 [Steve Henson]
322
323 *) Make `openssl version' output lines consistent.
324 [Ralf S. Engelschall]
325
326 *) Fix Win32 symbol export lists for BIO functions: Added
327 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
328 to ms/libeay{16,32}.def.
329 [Ralf S. Engelschall]
330
331 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
332 fine under Unix and passes some trivial tests I've now added. But the
333 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
334 added to make sure no one expects that this stuff really works in the
335 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
336 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
337 openssl_bio.xs.
338 [Ralf S. Engelschall]
339
340 *) Fix the generation of two part addresses in perl.
341 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
342
343 *) Add config entry for Linux on MIPS.
344 [John Tobey <jtobey@channel1.com>]
345
346 *) Make links whenever Configure is run, unless we are on Windoze.
347 [Ben Laurie]
348
349 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
350 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
351 in CRLs.
352 [Steve Henson]
353
354 *) Add a useful kludge to allow package maintainers to specify compiler and
355 other platforms details on the command line without having to patch the
356 Configure script everytime: One now can use ``perl Configure
357 <id>:<details>'', i.e. platform ids are allowed to have details appended
358 to them (seperated by colons). This is treated as there would be a static
359 pre-configured entry in Configure's %table under key <id> with value
360 <details> and ``perl Configure <id>'' is called. So, when you want to
361 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
362 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
363 now, which overrides the FreeBSD-elf entry on-the-fly.
364 [Ralf S. Engelschall]
365
366 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
367 [Ben Laurie]
368
369 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
370 on the `perl Configure ...' command line. This way one can compile
371 OpenSSL libraries with Position Independent Code (PIC) which is needed
372 for linking it into DSOs.
373 [Ralf S. Engelschall]
374
375 *) Remarkably, export ciphers were totally broken and no-one had noticed!
376 Fixed.
377 [Ben Laurie]
378
379 *) Cleaned up the LICENSE document: The official contact for any license
380 questions now is the OpenSSL core team under openssl-core@openssl.org.
381 And add a paragraph about the dual-license situation to make sure people
382 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
383 to the OpenSSL toolkit.
384 [Ralf S. Engelschall]
385
386 *) General source tree makefile cleanups: Made `making xxx in yyy...'
387 display consistent in the source tree and replaced `/bin/rm' by `rm'.
388 Additonally cleaned up the `make links' target: Remove unnecessary
389 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
390 to speed processing and no longer clutter the display with confusing
391 stuff. Instead only the actually done links are displayed.
392 [Ralf S. Engelschall]
393
394 *) Permit null encryption ciphersuites, used for authentication only. It used
395 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
396 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
397 encryption.
398 [Ben Laurie]
399
400 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
401 signed attributes when verifying signatures (this would break them),
402 the detached data encoding was wrong and public keys obtained using
403 X509_get_pubkey() weren't freed.
404 [Steve Henson]
405
406 *) Add text documentation for the BUFFER functions. Also added a work around
407 to a Win95 console bug. This was triggered by the password read stuff: the
408 last character typed gets carried over to the next fread(). If you were
409 generating a new cert request using 'req' for example then the last
410 character of the passphrase would be CR which would then enter the first
411 field as blank.
412 [Steve Henson]
413
414 *) Added the new `Includes OpenSSL Cryptography Software' button as
415 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
416 button and can be used by applications based on OpenSSL to show the
417 relationship to the OpenSSL project.
418 [Ralf S. Engelschall]
419
420 *) Remove confusing variables in function signatures in files
421 ssl/ssl_lib.c and ssl/ssl.h.
422 [Lennart Bong <lob@kulthea.stacken.kth.se>]
423
424 *) Don't install bss_file.c under PREFIX/include/
425 [Lennart Bong <lob@kulthea.stacken.kth.se>]
426
427 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
428 functions that return function pointers and has support for NT specific
429 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
430 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
431 unsigned to signed types: this was killing the Win32 compile.
432 [Steve Henson]
433
434 *) Add new certificate file to stack functions,
435 SSL_add_dir_cert_subjects_to_stack() and
436 SSL_add_file_cert_subjects_to_stack(). These largely supplant
437 SSL_load_client_CA_file(), and can be used to add multiple certs easily
438 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
439 This means that Apache-SSL and similar packages don't have to mess around
440 to add as many CAs as they want to the preferred list.
441 [Ben Laurie]
442
443 *) Experiment with doxygen documentation. Currently only partially applied to
444 ssl/ssl_lib.c.
445 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
446 openssl.doxy as the configuration file.
447 [Ben Laurie]
448
449 *) Get rid of remaining C++-style comments which strict C compilers hate.
450 [Ralf S. Engelschall, pointed out by Carlos Amengual]
451
452 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
453 compiled in by default: it has problems with large keys.
454 [Steve Henson]
455
456 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
457 DH private keys and/or callback functions which directly correspond to
458 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
459 is needed for applications which have to configure certificates on a
460 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
461 (e.g. s_server).
462 For the RSA certificate situation is makes no difference, but
463 for the DSA certificate situation this fixes the "no shared cipher"
464 problem where the OpenSSL cipher selection procedure failed because the
465 temporary keys were not overtaken from the context and the API provided
466 no way to reconfigure them.
467 The new functions now let applications reconfigure the stuff and they
468 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
469 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
470 non-public-API function ssl_cert_instantiate() is used as a helper
471 function and also to reduce code redundancy inside ssl_rsa.c.
472 [Ralf S. Engelschall]
473
474 *) Move s_server -dcert and -dkey options out of the undocumented feature
475 area because they are useful for the DSA situation and should be
476 recognized by the users.
477 [Ralf S. Engelschall]
478
479 *) Fix the cipher decision scheme for export ciphers: the export bits are
480 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
481 SSL_EXP_MASK. So, the original variable has to be used instead of the
482 already masked variable.
483 [Richard Levitte <levitte@stacken.kth.se>]
484
485 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
486 [Richard Levitte <levitte@stacken.kth.se>]
487
488 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
489 from `int' to `unsigned int' because it's a length and initialized by
490 EVP_DigestFinal() which expects an `unsigned int *'.
491 [Richard Levitte <levitte@stacken.kth.se>]
492
493 *) Don't hard-code path to Perl interpreter on shebang line of Configure
494 script. Instead use the usual Shell->Perl transition trick.
495 [Ralf S. Engelschall]
496
497 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
498 (in addition to RSA certificates) to match the behaviour of `openssl dsa
499 -noout -modulus' as it's already the case for `openssl rsa -noout
500 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
501 currently the public key is printed (a decision which was already done by
502 `openssl dsa -modulus' in the past) which serves a similar purpose.
503 Additionally the NO_RSA no longer completely removes the whole -modulus
504 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
505 now, too.
506 [Ralf S. Engelschall]
507
508 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
509 BIO. See the source (crypto/evp/bio_ok.c) for more info.
510 [Arne Ansper <arne@ats.cyber.ee>]
511
512 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
513 to be added. Now both 'req' and 'ca' can use new objects defined in the
514 config file.
515 [Steve Henson]
516
517 *) Add cool BIO that does syslog (or event log on NT).
518 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
519
520 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
521 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
522 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
523 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
524 [Ben Laurie]
525
526 *) Add preliminary config info for new extension code.
527 [Steve Henson]
528
529 *) Make RSA_NO_PADDING really use no padding.
530 [Ulf Moeller <ulf@fitug.de>]
531
532 *) Generate errors when private/public key check is done.
533 [Ben Laurie]
534
535 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
536 for some CRL extensions and new objects added.
537 [Steve Henson]
538
539 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
540 key usage extension and fuller support for authority key id.
541 [Steve Henson]
542
543 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
544 padding method for RSA, which is recommended for new applications in PKCS
545 #1 v2.0 (RFC 2437, October 1998).
546 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
547 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
548 against Bleichbacher's attack on RSA.
549 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
550 Ben Laurie]
551
552 *) Updates to the new SSL compression code
553 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
554
555 *) Fix so that the version number in the master secret, when passed
556 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
557 (because the server will not accept higher), that the version number
558 is 0x03,0x01, not 0x03,0x00
559 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
560
561 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
562 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
563 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
564 [Steve Henson]
565
566 *) Support for RAW extensions where an arbitrary extension can be
567 created by including its DER encoding. See apps/openssl.cnf for
568 an example.
569 [Steve Henson]
570
571 *) Make sure latest Perl versions don't interpret some generated C array
572 code as Perl array code in the crypto/err/err_genc.pl script.
573 [Lars Weber <3weber@informatik.uni-hamburg.de>]
574
575 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
576 not many people have the assembler. Various Win32 compilation fixes and
577 update to the INSTALL.W32 file with (hopefully) more accurate Win32
578 build instructions.
579 [Steve Henson]
580
581 *) Modify configure script 'Configure' to automatically create crypto/date.h
582 file under Win32 and also build pem.h from pem.org. New script
583 util/mkfiles.pl to create the MINFO file on environments that can't do a
584 'make files': perl util/mkfiles.pl >MINFO should work.
585 [Steve Henson]
586
587 *) Major rework of DES function declarations, in the pursuit of correctness
588 and purity. As a result, many evil casts evaporated, and some weirdness,
589 too. You may find this causes warnings in your code. Zapping your evil
590 casts will probably fix them. Mostly.
591 [Ben Laurie]
592
593 *) Fix for a typo in asn1.h. Bug fix to object creation script
594 obj_dat.pl. It considered a zero in an object definition to mean
595 "end of object": none of the objects in objects.h have any zeros
596 so it wasn't spotted.
597 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
598
599 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
600 Masking (CBCM). In the absence of test vectors, the best I have been able
601 to do is check that the decrypt undoes the encrypt, so far. Send me test
602 vectors if you have them.
603 [Ben Laurie]
604
605 *) Correct calculation of key length for export ciphers (too much space was
606 allocated for null ciphers). This has not been tested!
607 [Ben Laurie]
608
609 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
610 message is now correct (it understands "crypto" and "ssl" on its
611 command line). There is also now an "update" option. This will update
612 the util/ssleay.num and util/libeay.num files with any new functions.
613 If you do a:
614 perl util/mkdef.pl crypto ssl update
615 it will update them.
616 [Steve Henson]
617
618 *) Overhauled the Perl interface (perl/*):
619 - ported BN stuff to OpenSSL's different BN library
620 - made the perl/ source tree CVS-aware
621 - renamed the package from SSLeay to OpenSSL (the files still contain
622 their history because I've copied them in the repository)
623 - removed obsolete files (the test scripts will be replaced
624 by better Test::Harness variants in the future)
625 [Ralf S. Engelschall]
626
627 *) First cut for a very conservative source tree cleanup:
628 1. merge various obsolete readme texts into doc/ssleay.txt
629 where we collect the old documents and readme texts.
630 2. remove the first part of files where I'm already sure that we no
631 longer need them because of three reasons: either they are just temporary
632 files which were left by Eric or they are preserved original files where
633 I've verified that the diff is also available in the CVS via "cvs diff
634 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
635 the crypto/md/ stuff).
636 [Ralf S. Engelschall]
637
638 *) More extension code. Incomplete support for subject and issuer alt
639 name, issuer and authority key id. Change the i2v function parameters
640 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
641 what that's for :-) Fix to ASN1 macro which messed up
642 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
643 [Steve Henson]
644
645 *) Preliminary support for ENUMERATED type. This is largely copied from the
646 INTEGER code.
647 [Steve Henson]
648
649 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
650 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
651
652 *) Make sure `make rehash' target really finds the `openssl' program.
653 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
654
655 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
656 like to hear about it if this slows down other processors.
657 [Ben Laurie]
658
659 *) Add CygWin32 platform information to Configure script.
660 [Alan Batie <batie@aahz.jf.intel.com>]
661
662 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
663 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
664
665 *) New program nseq to manipulate netscape certificate sequences
666 [Steve Henson]
667
668 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
669 few typos.
670 [Steve Henson]
671
672 *) Fixes to BN code. Previously the default was to define BN_RECURSION
673 but the BN code had some problems that would cause failures when
674 doing certificate verification and some other functions.
675 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
676
677 *) Add ASN1 and PEM code to support netscape certificate sequences.
678 [Steve Henson]
679
680 *) Add ASN1 and PEM code to support netscape certificate sequences.
681 [Steve Henson]
682
683 *) Add several PKIX and private extended key usage OIDs.
684 [Steve Henson]
685
686 *) Modify the 'ca' program to handle the new extension code. Modify
687 openssl.cnf for new extension format, add comments.
688 [Steve Henson]
689
690 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
691 and add a sample to openssl.cnf so req -x509 now adds appropriate
692 CA extensions.
693 [Steve Henson]
694
695 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
696 error code, add initial support to X509_print() and x509 application.
697 [Steve Henson]
698
699 *) Takes a deep breath and start addding X509 V3 extension support code. Add
700 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
701 stuff is currently isolated and isn't even compiled yet.
702 [Steve Henson]
703
704 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
705 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
706 Removed the versions check from X509 routines when loading extensions:
707 this allows certain broken certificates that don't set the version
708 properly to be processed.
709 [Steve Henson]
710
711 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
712 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
713 can still be regenerated with "make depend".
714 [Ben Laurie]
715
716 *) Spelling mistake in C version of CAST-128.
717 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
718
719 *) Changes to the error generation code. The perl script err-code.pl
720 now reads in the old error codes and retains the old numbers, only
721 adding new ones if necessary. It also only changes the .err files if new
722 codes are added. The makefiles have been modified to only insert errors
723 when needed (to avoid needlessly modifying header files). This is done
724 by only inserting errors if the .err file is newer than the auto generated
725 C file. To rebuild all the error codes from scratch (the old behaviour)
726 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
727 or delete all the .err files.
728 [Steve Henson]
729
730 *) CAST-128 was incorrectly implemented for short keys. The C version has
731 been fixed, but is untested. The assembler versions are also fixed, but
732 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
733 to regenerate it if needed.
734 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
735 Hagino <itojun@kame.net>]
736
737 *) File was opened incorrectly in randfile.c.
738 [Ulf Möller <ulf@fitug.de>]
739
740 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
741 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
742 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
743 al: it's just almost always a UTCTime. Note this patch adds new error
744 codes so do a "make errors" if there are problems.
745 [Steve Henson]
746
747 *) Correct Linux 1 recognition in config.
748 [Ulf Möller <ulf@fitug.de>]
749
750 *) Remove pointless MD5 hash when using DSA keys in ca.
751 [Anonymous <nobody@replay.com>]
752
753 *) Generate an error if given an empty string as a cert directory. Also
754 generate an error if handed NULL (previously returned 0 to indicate an
755 error, but didn't set one).
756 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
757
758 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
759 [Ben Laurie]
760
761 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
762 parameters. This was causing a warning which killed off the Win32 compile.
763 [Steve Henson]
764
765 *) Remove C++ style comments from crypto/bn/bn_local.h.
766 [Neil Costigan <neil.costigan@celocom.com>]
767
768 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
769 based on a text string, looking up short and long names and finally
770 "dot" format. The "dot" format stuff didn't work. Added new function
771 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
772 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
773 OID is not part of the table.
774 [Steve Henson]
775
776 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
777 X509_LOOKUP_by_alias().
778 [Ben Laurie]
779
780 *) Sort openssl functions by name.
781 [Ben Laurie]
782
783 *) Get the gendsa program working (hopefully) and add it to app list. Remove
784 encryption from sample DSA keys (in case anyone is interested the password
785 was "1234").
786 [Steve Henson]
787
788 *) Make _all_ *_free functions accept a NULL pointer.
789 [Frans Heymans <fheymans@isaserver.be>]
790
791 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
792 NULL pointers.
793 [Anonymous <nobody@replay.com>]
794
795 *) s_server should send the CAfile as acceptable CAs, not its own cert.
796 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
797
798 *) Don't blow it for numeric -newkey arguments to apps/req.
799 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
800
801 *) Temp key "for export" tests were wrong in s3_srvr.c.
802 [Anonymous <nobody@replay.com>]
803
804 *) Add prototype for temp key callback functions
805 SSL_CTX_set_tmp_{rsa,dh}_callback().
806 [Ben Laurie]
807
808 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
809 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
810 [Steve Henson]
811
812 *) X509_name_add_entry() freed the wrong thing after an error.
813 [Arne Ansper <arne@ats.cyber.ee>]
814
815 *) rsa_eay.c would attempt to free a NULL context.
816 [Arne Ansper <arne@ats.cyber.ee>]
817
818 *) BIO_s_socket() had a broken should_retry() on Windoze.
819 [Arne Ansper <arne@ats.cyber.ee>]
820
821 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
822 [Arne Ansper <arne@ats.cyber.ee>]
823
824 *) Make sure the already existing X509_STORE->depth variable is initialized
825 in X509_STORE_new(), but document the fact that this variable is still
826 unused in the certificate verification process.
827 [Ralf S. Engelschall]
828
829 *) Fix the various library and apps files to free up pkeys obtained from
830 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
831 [Steve Henson]
832
833 *) Fix reference counting in X509_PUBKEY_get(). This makes
834 demos/maurice/example2.c work, amongst others, probably.
835 [Steve Henson and Ben Laurie]
836
837 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
838 `openssl' and second, the shortcut symlinks for the `openssl <command>'
839 are no longer created. This way we have a single and consistent command
840 line interface `openssl <command>', similar to `cvs <command>'.
841 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
842
843 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
844 BIT STRING wrapper always have zero unused bits.
845 [Steve Henson]
846
847 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
848 [Steve Henson]
849
850 *) Make the top-level INSTALL documentation easier to understand.
851 [Paul Sutton]
852
853 *) Makefiles updated to exit if an error occurs in a sub-directory
854 make (including if user presses ^C) [Paul Sutton]
855
856 *) Make Montgomery context stuff explicit in RSA data structure.
857 [Ben Laurie]
858
859 *) Fix build order of pem and err to allow for generated pem.h.
860 [Ben Laurie]
861
862 *) Fix renumbering bug in X509_NAME_delete_entry().
863 [Ben Laurie]
864
865 *) Enhanced the err-ins.pl script so it makes the error library number
866 global and can add a library name. This is needed for external ASN1 and
867 other error libraries.
868 [Steve Henson]
869
870 *) Fixed sk_insert which never worked properly.
871 [Steve Henson]
872
873 *) Fix ASN1 macros so they can handle indefinite length construted
874 EXPLICIT tags. Some non standard certificates use these: they can now
875 be read in.
876 [Steve Henson]
877
878 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
879 into a single doc/ssleay.txt bundle. This way the information is still
880 preserved but no longer messes up this directory. Now it's new room for
881 the new set of documenation files.
882 [Ralf S. Engelschall]
883
884 *) SETs were incorrectly DER encoded. This was a major pain, because they
885 shared code with SEQUENCEs, which aren't coded the same. This means that
886 almost everything to do with SETs or SEQUENCEs has either changed name or
887 number of arguments.
888 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
889
890 *) Fix test data to work with the above.
891 [Ben Laurie]
892
893 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
894 was already fixed by Eric for 0.9.1 it seems.
895 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
896
897 *) Autodetect FreeBSD3.
898 [Ben Laurie]
899
900 *) Fix various bugs in Configure. This affects the following platforms:
901 nextstep
902 ncr-scde
903 unixware-2.0
904 unixware-2.0-pentium
905 sco5-cc.
906 [Ben Laurie]
907
908 *) Eliminate generated files from CVS. Reorder tests to regenerate files
909 before they are needed.
910 [Ben Laurie]
911
912 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
913 [Ben Laurie]
914
915 Changes between 0.9.1b and 0.9.1c
916
917 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
918 changed SSLeay to OpenSSL in version strings.
919 [Ralf S. Engelschall]
920
921 *) Some fixups to the top-level documents.
922 [Paul Sutton]
923
924 *) Fixed the nasty bug where rsaref.h was not found under compile-time
925 because the symlink to include/ was missing.
926 [Ralf S. Engelschall]
927
928 *) Incorporated the popular no-RSA/DSA-only patches
929 which allow to compile a RSA-free SSLeay.
930 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
931
932 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
933 when "ssleay" is still not found.
934 [Ralf S. Engelschall]
935
936 *) Added more platforms to Configure: Cray T3E, HPUX 11,
937 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
938
939 *) Updated the README file.
940 [Ralf S. Engelschall]
941
942 *) Added various .cvsignore files in the CVS repository subdirs
943 to make a "cvs update" really silent.
944 [Ralf S. Engelschall]
945
946 *) Recompiled the error-definition header files and added
947 missing symbols to the Win32 linker tables.
948 [Ralf S. Engelschall]
949
950 *) Cleaned up the top-level documents;
951 o new files: CHANGES and LICENSE
952 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
953 o merged COPYRIGHT into LICENSE
954 o removed obsolete TODO file
955 o renamed MICROSOFT to INSTALL.W32
956 [Ralf S. Engelschall]
957
958 *) Removed dummy files from the 0.9.1b source tree:
959 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
960 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
961 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
962 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
963 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
964 [Ralf S. Engelschall]
965
966 *) Added various platform portability fixes.
967 [Mark J. Cox]
968
969 *) The Genesis of the OpenSSL rpject:
970 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
971 Young and Tim J. Hudson created while they were working for C2Net until
972 summer 1998.
973 [The OpenSSL Project]
974
975 Changes between 0.9.0b and 0.9.1b
976
977 *) Updated a few CA certificates under certs/
978 [Eric A. Young]
979
980 *) Changed some BIGNUM api stuff.
981 [Eric A. Young]
982
983 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
984 DGUX x86, Linux Alpha, etc.
985 [Eric A. Young]
986
987 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
988 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
989 available).
990 [Eric A. Young]
991
992 *) Add -strparse option to asn1pars program which parses nested
993 binary structures
994 [Dr Stephen Henson <shenson@bigfoot.com>]
995
996 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
997 [Eric A. Young]
998
999 *) DSA fix for "ca" program.
1000 [Eric A. Young]
1001
1002 *) Added "-genkey" option to "dsaparam" program.
1003 [Eric A. Young]
1004
1005 *) Added RIPE MD160 (rmd160) message digest.
1006 [Eric A. Young]
1007
1008 *) Added -a (all) option to "ssleay version" command.
1009 [Eric A. Young]
1010
1011 *) Added PLATFORM define which is the id given to Configure.
1012 [Eric A. Young]
1013
1014 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1015 [Eric A. Young]
1016
1017 *) Extended the ASN.1 parser routines.
1018 [Eric A. Young]
1019
1020 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1021 [Eric A. Young]
1022
1023 *) Added a BN_CTX to the BN library.
1024 [Eric A. Young]
1025
1026 *) Fixed the weak key values in DES library
1027 [Eric A. Young]
1028
1029 *) Changed API in EVP library for cipher aliases.
1030 [Eric A. Young]
1031
1032 *) Added support for RC2/64bit cipher.
