4
5
6 Changes between 0.9.2b and 0.9.3
7
8 *) Add support for CRL distribution points extension. Add Certificate
9 Policies and CRL distribution points documentation.
10 [Steve Henson]
11
12 *) Move the autogenerated header file parts to crypto/opensslconf.h.
13 [Ulf Möller]
14
15 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
16 8 of keying material. Merlin has also confirmed interop with this fix
17 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
18 [Merlin Hughes <merlin@baltimore.ie>]
19
20 *) Fix lots of warnings.
21 [Richard Levitte <levitte@stacken.kth.se>]
22
23 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
24 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
25 [Richard Levitte <levitte@stacken.kth.se>]
26
27 *) Fix problems with sizeof(long) == 8.
28 [Andy Polyakov <appro@fy.chalmers.se>]
29
30 *) Change functions to ANSI C.
31 [Ulf Möller]
32
33 *) Fix typos in error codes.
34 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
35
36 *) Remove defunct assembler files from Configure.
37 [Ulf Möller]
38
39 *) SPARC v8 assembler BIGNUM implementation.
40 [Andy Polyakov <appro@fy.chalmers.se>]
41
42 *) Support for Certificate Policies extension: both print and set.
43 Various additions to support the r2i method this uses.
44 [Steve Henson]
45
46 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
47 return a const string when you are expecting an allocated buffer.
48 [Ben Laurie]
49
50 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
51 types DirectoryString and DisplayText.
52 [Steve Henson]
53
54 *) Add code to allow r2i extensions to access the configuration database,
55 add an LHASH database driver and add several ctx helper functions.
56 [Steve Henson]
57
58 *) Fix an evil bug in bn_expand2() which caused various BN functions to
59 fail when they extended the size of a BIGNUM.
60 [Steve Henson]
61
62 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
63 support typesafe stack.
64 [Steve Henson]
65
66 *) Fix typo in SSL_[gs]et_options().
67 [Nils Frostberg <nils@medcom.se>]
68
69 *) Delete various functions and files that belonged to the (now obsolete)
70 old X509V3 handling code.
71 [Steve Henson]
72
73 *) New Configure option "rsaref".
74 [Ulf Möller]
75
76 *) Don't auto-generate pem.h.
77 [Bodo Moeller]
78
79 *) Introduce type-safe ASN.1 SETs.
80 [Ben Laurie]
81
82 *) Introduce type-safe STACKs. This will almost certainly break lots of code
83 that links with OpenSSL (well at least cause lots of warnings), but fear
84 not: the conversion is trivial, and it eliminates loads of evil casts. A
85 few STACKed things have been converted already. Feel free to convert more.
86 In the fullness of time, I'll do away with the STACK type altogether.
87 [Ben Laurie]
88
89 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
90 specified in <certfile> by updating the entry in the index.txt file.
91 This way one no longer has to edit the index.txt file manually for
92 revoking a certificate. The -revoke option does the gory details now.
93 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
94
95 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
96 `-text' option at all and this way the `-noout -text' combination was
97 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
98 [Ralf S. Engelschall]
99
100 *) Make sure a corresponding plain text error message exists for the
101 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
102 verify callback function determined that a certificate was revoked.
103 [Ralf S. Engelschall]
104
105 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
106 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
107 all available cipers including rc5, which was forgotten until now.
108 In order to let the testing shell script know which algorithms
109 are available, a new (up to now undocumented) command
110 "openssl list-cipher-commands" is used.
111 [Bodo Moeller]
112
113 *) Bugfix: s_client occasionally would sleep in select() when
114 it should have checked SSL_pending() first.
115 [Bodo Moeller]
116
117 *) New functions DSA_do_sign and DSA_do_verify to provide access to
118 the raw DSA values prior to ASN.1 encoding.
119 [Ulf Möller]
120
121 *) Tweaks to Configure
122 Niels Poppe <niels@netbox.org>
123
124 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
125 yet...
126 [Steve Henson]
127
128 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
129 [Ulf Möller]
130
131 *) New config option to avoid instructions that are illegal on the 80386.
132 The default code is faster, but requires at least a 486.
133 [Ulf Möller]
134
135 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
136 SSL2_SERVER_VERSION (not used at all) macros, which are now the
137 same as SSL2_VERSION anyway.
138 [Bodo Moeller]
139
140 *) New "-showcerts" option for s_client.
141 [Bodo Moeller]
142
143 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
144 application. Various cleanups and fixes.
145 [Steve Henson]
146
147 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
148 modify error routines to work internally. Add error codes and PBE init
149 to library startup routines.
150 [Steve Henson]
151
152 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
153 packing functions to asn1 and evp. Changed function names and error
154 codes along the way.
155 [Steve Henson]
156
157 *) PKCS12 integration: and so it begins... First of several patches to
158 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
159 objects to objects.h
160 [Steve Henson]
161
162 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
163 and display support for Thawte strong extranet extension.
164 [Steve Henson]
165
166 *) Add LinuxPPC support.
167 [Jeff Dubrule <igor@pobox.org>]
168
169 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
170 bn_div_words in alpha.s.
171 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
172
173 *) Make sure the RSA OAEP test is skipped under -DRSAref because
174 OAEP isn't supported when OpenSSL is built with RSAref.
175 [Ulf Moeller <ulf@fitug.de>]
176
177 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
178 so they no longer are missing under -DNOPROTO.
179 [Soren S. Jorvang <soren@t.dk>]
180
181 Changes between 0.9.1c and 0.9.2b
182
183 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
184 doesn't work when the session is reused. Coming soon!
185 [Ben Laurie]
186
187 *) Fix a security hole, that allows sessions to be reused in the wrong
188 context thus bypassing client cert protection! All software that uses
189 client certs and session caches in multiple contexts NEEDS PATCHING to
190 allow session reuse! A fuller solution is in the works.
191 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
192
193 *) Some more source tree cleanups (removed obsolete files
194 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
195 permission on "config" script to be executable) and a fix for the INSTALL
196 document.
197 [Ulf Moeller <ulf@fitug.de>]
198
199 *) Remove some legacy and erroneous uses of malloc, free instead of
200 Malloc, Free.
201 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
202
203 *) Make rsa_oaep_test return non-zero on error.
204 [Ulf Moeller <ulf@fitug.de>]
205
206 *) Add support for native Solaris shared libraries. Configure
207 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
208 if someone would make that last step automatic.
209 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
210
211 *) ctx_size was not built with the right compiler during "make links". Fixed.
212 [Ben Laurie]
213
214 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
215 except NULL ciphers". This means the default cipher list will no longer
216 enable NULL ciphers. They need to be specifically enabled e.g. with
217 the string "DEFAULT:eNULL".
218 [Steve Henson]
219
220 *) Fix to RSA private encryption routines: if p < q then it would
221 occasionally produce an invalid result. This will only happen with
222 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
223 [Steve Henson]
224
225 *) Be less restrictive and allow also `perl util/perlpath.pl
226 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
227 because this way one can also use an interpreter named `perl5' (which is
228 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
229 installed as `perl').
230 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
231
232 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
233 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
234
235 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
236 advapi32.lib to Win32 build and change the pem test comparision
237 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
238 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
239 and crypto/des/ede_cbcm_enc.c.
240 [Steve Henson]
241
242 *) DES quad checksum was broken on big-endian architectures. Fixed.
243 [Ben Laurie]
244
245 *) Comment out two functions in bio.h that aren't implemented. Fix up the
246 Win32 test batch file so it (might) work again. The Win32 test batch file
247 is horrible: I feel ill....
248 [Steve Henson]
249
250 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
251 in e_os.h. Audit of header files to check ANSI and non ANSI
252 sections: 10 functions were absent from non ANSI section and not exported
253 from Windows DLLs. Fixed up libeay.num for new functions.
254 [Steve Henson]
255
256 *) Make `openssl version' output lines consistent.
257 [Ralf S. Engelschall]
258
259 *) Fix Win32 symbol export lists for BIO functions: Added
260 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
261 to ms/libeay{16,32}.def.
262 [Ralf S. Engelschall]
263
264 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
265 fine under Unix and passes some trivial tests I've now added. But the
266 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
267 added to make sure no one expects that this stuff really works in the
268 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
269 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
270 openssl_bio.xs.
271 [Ralf S. Engelschall]
272
273 *) Fix the generation of two part addresses in perl.
274 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
275
276 *) Add config entry for Linux on MIPS.
277 [John Tobey <jtobey@channel1.com>]
278
279 *) Make links whenever Configure is run, unless we are on Windoze.
280 [Ben Laurie]
281
282 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
283 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
284 in CRLs.
285 [Steve Henson]
286
287 *) Add a useful kludge to allow package maintainers to specify compiler and
288 other platforms details on the command line without having to patch the
289 Configure script everytime: One now can use ``perl Configure
290 <id>:<details>'', i.e. platform ids are allowed to have details appended
291 to them (seperated by colons). This is treated as there would be a static
292 pre-configured entry in Configure's %table under key <id> with value
293 <details> and ``perl Configure <id>'' is called. So, when you want to
294 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
295 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
296 now, which overrides the FreeBSD-elf entry on-the-fly.
297 [Ralf S. Engelschall]
298
299 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
300 [Ben Laurie]
301
302 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
303 on the `perl Configure ...' command line. This way one can compile
304 OpenSSL libraries with Position Independent Code (PIC) which is needed
305 for linking it into DSOs.
306 [Ralf S. Engelschall]
307
308 *) Remarkably, export ciphers were totally broken and no-one had noticed!
309 Fixed.
310 [Ben Laurie]
311
312 *) Cleaned up the LICENSE document: The official contact for any license
313 questions now is the OpenSSL core team under openssl-core@openssl.org.
314 And add a paragraph about the dual-license situation to make sure people
315 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
316 to the OpenSSL toolkit.
317 [Ralf S. Engelschall]
318
319 *) General source tree makefile cleanups: Made `making xxx in yyy...'
320 display consistent in the source tree and replaced `/bin/rm' by `rm'.
321 Additonally cleaned up the `make links' target: Remove unnecessary
322 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
323 to speed processing and no longer clutter the display with confusing
324 stuff. Instead only the actually done links are displayed.
325 [Ralf S. Engelschall]
326
327 *) Permit null encryption ciphersuites, used for authentication only. It used
328 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
329 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
330 encryption.
331 [Ben Laurie]
332
333 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
334 signed attributes when verifying signatures (this would break them),
335 the detached data encoding was wrong and public keys obtained using
336 X509_get_pubkey() weren't freed.
337 [Steve Henson]
338
339 *) Add text documentation for the BUFFER functions. Also added a work around
340 to a Win95 console bug. This was triggered by the password read stuff: the
341 last character typed gets carried over to the next fread(). If you were
342 generating a new cert request using 'req' for example then the last
343 character of the passphrase would be CR which would then enter the first
344 field as blank.
345 [Steve Henson]
346
347 *) Added the new `Includes OpenSSL Cryptography Software' button as
348 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
349 button and can be used by applications based on OpenSSL to show the
350 relationship to the OpenSSL project.
351 [Ralf S. Engelschall]
352
353 *) Remove confusing variables in function signatures in files
354 ssl/ssl_lib.c and ssl/ssl.h.
355 [Lennart Bong <lob@kulthea.stacken.kth.se>]
356
357 *) Don't install bss_file.c under PREFIX/include/
358 [Lennart Bong <lob@kulthea.stacken.kth.se>]
359
360 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
361 functions that return function pointers and has support for NT specific
362 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
363 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
364 unsigned to signed types: this was killing the Win32 compile.
365 [Steve Henson]
366
367 *) Add new certificate file to stack functions,
368 SSL_add_dir_cert_subjects_to_stack() and
369 SSL_add_file_cert_subjects_to_stack(). These largely supplant
370 SSL_load_client_CA_file(), and can be used to add multiple certs easily
371 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
372 This means that Apache-SSL and similar packages don't have to mess around
373 to add as many CAs as they want to the preferred list.
374 [Ben Laurie]
375
376 *) Experiment with doxygen documentation. Currently only partially applied to
377 ssl/ssl_lib.c.
378 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
379 openssl.doxy as the configuration file.
380 [Ben Laurie]
381
382 *) Get rid of remaining C++-style comments which strict C compilers hate.
383 [Ralf S. Engelschall, pointed out by Carlos Amengual]
384
385 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
386 compiled in by default: it has problems with large keys.
387 [Steve Henson]
388
389 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
390 DH private keys and/or callback functions which directly correspond to
391 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
392 is needed for applications which have to configure certificates on a
393 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
394 (e.g. s_server).
395 For the RSA certificate situation is makes no difference, but
396 for the DSA certificate situation this fixes the "no shared cipher"
397 problem where the OpenSSL cipher selection procedure failed because the
398 temporary keys were not overtaken from the context and the API provided
399 no way to reconfigure them.
400 The new functions now let applications reconfigure the stuff and they
401 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
402 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
403 non-public-API function ssl_cert_instantiate() is used as a helper
404 function and also to reduce code redundancy inside ssl_rsa.c.
405 [Ralf S. Engelschall]
406
407 *) Move s_server -dcert and -dkey options out of the undocumented feature
408 area because they are useful for the DSA situation and should be
409 recognized by the users.
410 [Ralf S. Engelschall]
411
412 *) Fix the cipher decision scheme for export ciphers: the export bits are
413 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
414 SSL_EXP_MASK. So, the original variable has to be used instead of the
415 already masked variable.
416 [Richard Levitte <levitte@stacken.kth.se>]
417
418 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
419 [Richard Levitte <levitte@stacken.kth.se>]
420
421 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
422 from `int' to `unsigned int' because it's a length and initialized by
423 EVP_DigestFinal() which expects an `unsigned int *'.
424 [Richard Levitte <levitte@stacken.kth.se>]
425
426 *) Don't hard-code path to Perl interpreter on shebang line of Configure
427 script. Instead use the usual Shell->Perl transition trick.
428 [Ralf S. Engelschall]
429
430 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
431 (in addition to RSA certificates) to match the behaviour of `openssl dsa
432 -noout -modulus' as it's already the case for `openssl rsa -noout
433 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
434 currently the public key is printed (a decision which was already done by
435 `openssl dsa -modulus' in the past) which serves a similar purpose.
436 Additionally the NO_RSA no longer completely removes the whole -modulus
437 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
438 now, too.
439 [Ralf S. Engelschall]
440
441 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
442 BIO. See the source (crypto/evp/bio_ok.c) for more info.
443 [Arne Ansper <arne@ats.cyber.ee>]
444
445 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
446 to be added. Now both 'req' and 'ca' can use new objects defined in the
447 config file.
448 [Steve Henson]
449
450 *) Add cool BIO that does syslog (or event log on NT).
451 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
452
453 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
454 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
455 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
456 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
457 [Ben Laurie]
458
459 *) Add preliminary config info for new extension code.
460 [Steve Henson]
461
462 *) Make RSA_NO_PADDING really use no padding.
463 [Ulf Moeller <ulf@fitug.de>]
464
465 *) Generate errors when private/public key check is done.
466 [Ben Laurie]
467
468 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
469 for some CRL extensions and new objects added.
470 [Steve Henson]
471
472 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
473 key usage extension and fuller support for authority key id.
474 [Steve Henson]
475
476 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
477 padding method for RSA, which is recommended for new applications in PKCS
478 #1 v2.0 (RFC 2437, October 1998).
479 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
480 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
481 against Bleichbacher's attack on RSA.
482 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
483 Ben Laurie]
484
485 *) Updates to the new SSL compression code
486 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
487
488 *) Fix so that the version number in the master secret, when passed
489 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
490 (because the server will not accept higher), that the version number
491 is 0x03,0x01, not 0x03,0x00
492 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
493
494 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
495 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
496 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
497 [Steve Henson]
498
499 *) Support for RAW extensions where an arbitrary extension can be
500 created by including its DER encoding. See apps/openssl.cnf for
501 an example.
502 [Steve Henson]
503
504 *) Make sure latest Perl versions don't interpret some generated C array
505 code as Perl array code in the crypto/err/err_genc.pl script.
506 [Lars Weber <3weber@informatik.uni-hamburg.de>]
507
508 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
509 not many people have the assembler. Various Win32 compilation fixes and
510 update to the INSTALL.W32 file with (hopefully) more accurate Win32
511 build instructions.
512 [Steve Henson]
513
514 *) Modify configure script 'Configure' to automatically create crypto/date.h
515 file under Win32 and also build pem.h from pem.org. New script
516 util/mkfiles.pl to create the MINFO file on environments that can't do a
517 'make files': perl util/mkfiles.pl >MINFO should work.
518 [Steve Henson]
519
520 *) Major rework of DES function declarations, in the pursuit of correctness
521 and purity. As a result, many evil casts evaporated, and some weirdness,
522 too. You may find this causes warnings in your code. Zapping your evil
523 casts will probably fix them. Mostly.
524 [Ben Laurie]
525
526 *) Fix for a typo in asn1.h. Bug fix to object creation script
527 obj_dat.pl. It considered a zero in an object definition to mean
528 "end of object": none of the objects in objects.h have any zeros
529 so it wasn't spotted.
530 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
531
532 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
533 Masking (CBCM). In the absence of test vectors, the best I have been able
534 to do is check that the decrypt undoes the encrypt, so far. Send me test
535 vectors if you have them.
536 [Ben Laurie]
537
538 *) Correct calculation of key length for export ciphers (too much space was
539 allocated for null ciphers). This has not been tested!
540 [Ben Laurie]
541
542 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
543 message is now correct (it understands "crypto" and "ssl" on its
544 command line). There is also now an "update" option. This will update
545 the util/ssleay.num and util/libeay.num files with any new functions.
546 If you do a:
547 perl util/mkdef.pl crypto ssl update
548 it will update them.
549 [Steve Henson]
550
551 *) Overhauled the Perl interface (perl/*):
552 - ported BN stuff to OpenSSL's different BN library
553 - made the perl/ source tree CVS-aware
554 - renamed the package from SSLeay to OpenSSL (the files still contain
555 their history because I've copied them in the repository)
556 - removed obsolete files (the test scripts will be replaced
557 by better Test::Harness variants in the future)
558 [Ralf S. Engelschall]
559
560 *) First cut for a very conservative source tree cleanup:
561 1. merge various obsolete readme texts into doc/ssleay.txt
562 where we collect the old documents and readme texts.
563 2. remove the first part of files where I'm already sure that we no
564 longer need them because of three reasons: either they are just temporary
565 files which were left by Eric or they are preserved original files where
566 I've verified that the diff is also available in the CVS via "cvs diff
567 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
568 the crypto/md/ stuff).
569 [Ralf S. Engelschall]
570
571 *) More extension code. Incomplete support for subject and issuer alt
572 name, issuer and authority key id. Change the i2v function parameters
573 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
574 what that's for :-) Fix to ASN1 macro which messed up
575 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
576 [Steve Henson]
577
578 *) Preliminary support for ENUMERATED type. This is largely copied from the
579 INTEGER code.
580 [Steve Henson]
581
582 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
583 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
584
585 *) Make sure `make rehash' target really finds the `openssl' program.
586 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
587
588 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
589 like to hear about it if this slows down other processors.
590 [Ben Laurie]
591
592 *) Add CygWin32 platform information to Configure script.
593 [Alan Batie <batie@aahz.jf.intel.com>]
594
595 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
596 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
597
598 *) New program nseq to manipulate netscape certificate sequences
599 [Steve Henson]
600
601 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
602 few typos.
603 [Steve Henson]
604
605 *) Fixes to BN code. Previously the default was to define BN_RECURSION
606 but the BN code had some problems that would cause failures when
607 doing certificate verification and some other functions.
608 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
609
610 *) Add ASN1 and PEM code to support netscape certificate sequences.
611 [Steve Henson]
612
613 *) Add ASN1 and PEM code to support netscape certificate sequences.
614 [Steve Henson]
615
616 *) Add several PKIX and private extended key usage OIDs.
617 [Steve Henson]
618
619 *) Modify the 'ca' program to handle the new extension code. Modify
620 openssl.cnf for new extension format, add comments.
621 [Steve Henson]
622
623 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
624 and add a sample to openssl.cnf so req -x509 now adds appropriate
625 CA extensions.
626 [Steve Henson]
627
628 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
629 error code, add initial support to X509_print() and x509 application.
630 [Steve Henson]
631
632 *) Takes a deep breath and start addding X509 V3 extension support code. Add
633 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
634 stuff is currently isolated and isn't even compiled yet.
635 [Steve Henson]
636
637 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
638 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
639 Removed the versions check from X509 routines when loading extensions:
640 this allows certain broken certificates that don't set the version
641 properly to be processed.
642 [Steve Henson]
643
644 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
645 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
646 can still be regenerated with "make depend".
647 [Ben Laurie]
648
649 *) Spelling mistake in C version of CAST-128.
650 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
651
652 *) Changes to the error generation code. The perl script err-code.pl
653 now reads in the old error codes and retains the old numbers, only
654 adding new ones if necessary. It also only changes the .err files if new
655 codes are added. The makefiles have been modified to only insert errors
656 when needed (to avoid needlessly modifying header files). This is done
657 by only inserting errors if the .err file is newer than the auto generated
658 C file. To rebuild all the error codes from scratch (the old behaviour)
659 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
660 or delete all the .err files.
661 [Steve Henson]
662
663 *) CAST-128 was incorrectly implemented for short keys. The C version has
664 been fixed, but is untested. The assembler versions are also fixed, but
665 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
666 to regenerate it if needed.
667 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
668 Hagino <itojun@kame.net>]
669
670 *) File was opened incorrectly in randfile.c.
671 [Ulf Möller <ulf@fitug.de>]
672
673 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
674 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
675 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
676 al: it's just almost always a UTCTime. Note this patch adds new error
677 codes so do a "make errors" if there are problems.
678 [Steve Henson]
679
680 *) Correct Linux 1 recognition in config.
681 [Ulf Möller <ulf@fitug.de>]
682
683 *) Remove pointless MD5 hash when using DSA keys in ca.
684 [Anonymous <nobody@replay.com>]
685
686 *) Generate an error if given an empty string as a cert directory. Also
687 generate an error if handed NULL (previously returned 0 to indicate an
688 error, but didn't set one).
689 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
690
691 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
692 [Ben Laurie]
693
694 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
695 parameters. This was causing a warning which killed off the Win32 compile.
696 [Steve Henson]
697
698 *) Remove C++ style comments from crypto/bn/bn_local.h.
699 [Neil Costigan <neil.costigan@celocom.com>]
700
701 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
702 based on a text string, looking up short and long names and finally
703 "dot" format. The "dot" format stuff didn't work. Added new function
704 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
705 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
706 OID is not part of the table.
707 [Steve Henson]
708
709 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
710 X509_LOOKUP_by_alias().
711 [Ben Laurie]
712
713 *) Sort openssl functions by name.
714 [Ben Laurie]
715
716 *) Get the gendsa program working (hopefully) and add it to app list. Remove
717 encryption from sample DSA keys (in case anyone is interested the password
718 was "1234").
719 [Steve Henson]
720
721 *) Make _all_ *_free functions accept a NULL pointer.
722 [Frans Heymans <fheymans@isaserver.be>]
723
724 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
725 NULL pointers.
726 [Anonymous <nobody@replay.com>]
727
728 *) s_server should send the CAfile as acceptable CAs, not its own cert.
729 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
730
731 *) Don't blow it for numeric -newkey arguments to apps/req.
732 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
733
734 *) Temp key "for export" tests were wrong in s3_srvr.c.
735 [Anonymous <nobody@replay.com>]
736
737 *) Add prototype for temp key callback functions
738 SSL_CTX_set_tmp_{rsa,dh}_callback().
739 [Ben Laurie]
740
741 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
742 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
743 [Steve Henson]
744
745 *) X509_name_add_entry() freed the wrong thing after an error.
746 [Arne Ansper <arne@ats.cyber.ee>]
747
748 *) rsa_eay.c would attempt to free a NULL context.
749 [Arne Ansper <arne@ats.cyber.ee>]
750
751 *) BIO_s_socket() had a broken should_retry() on Windoze.
752 [Arne Ansper <arne@ats.cyber.ee>]
753
754 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
755 [Arne Ansper <arne@ats.cyber.ee>]
756
757 *) Make sure the already existing X509_STORE->depth variable is initialized
758 in X509_STORE_new(), but document the fact that this variable is still
759 unused in the certificate verification process.
760 [Ralf S. Engelschall]
761
762 *) Fix the various library and apps files to free up pkeys obtained from
763 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
764 [Steve Henson]
765
766 *) Fix reference counting in X509_PUBKEY_get(). This makes
767 demos/maurice/example2.c work, amongst others, probably.
768 [Steve Henson and Ben Laurie]
769
770 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
771 `openssl' and second, the shortcut symlinks for the `openssl <command>'
772 are no longer created. This way we have a single and consistent command
773 line interface `openssl <command>', similar to `cvs <command>'.
774 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
775
776 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
777 BIT STRING wrapper always have zero unused bits.
778 [Steve Henson]
779
780 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
781 [Steve Henson]
782
783 *) Make the top-level INSTALL documentation easier to understand.
784 [Paul Sutton]
785
786 *) Makefiles updated to exit if an error occurs in a sub-directory
787 make (including if user presses ^C) [Paul Sutton]
788
789 *) Make Montgomery context stuff explicit in RSA data structure.
790 [Ben Laurie]
791
792 *) Fix build order of pem and err to allow for generated pem.h.
793 [Ben Laurie]
794
795 *) Fix renumbering bug in X509_NAME_delete_entry().
796 [Ben Laurie]
797
798 *) Enhanced the err-ins.pl script so it makes the error library number
799 global and can add a library name. This is needed for external ASN1 and
800 other error libraries.
801 [Steve Henson]
802
803 *) Fixed sk_insert which never worked properly.
804 [Steve Henson]
805
806 *) Fix ASN1 macros so they can handle indefinite length construted
807 EXPLICIT tags. Some non standard certificates use these: they can now
808 be read in.
809 [Steve Henson]
810
811 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
812 into a single doc/ssleay.txt bundle. This way the information is still
813 preserved but no longer messes up this directory. Now it's new room for
814 the new set of documenation files.
815 [Ralf S. Engelschall]
816
817 *) SETs were incorrectly DER encoded. This was a major pain, because they
818 shared code with SEQUENCEs, which aren't coded the same. This means that
819 almost everything to do with SETs or SEQUENCEs has either changed name or
820 number of arguments.
821 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
822
823 *) Fix test data to work with the above.
824 [Ben Laurie]
825
826 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
827 was already fixed by Eric for 0.9.1 it seems.
828 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
829
830 *) Autodetect FreeBSD3.
831 [Ben Laurie]
832
833 *) Fix various bugs in Configure. This affects the following platforms:
834 nextstep
835 ncr-scde
836 unixware-2.0
837 unixware-2.0-pentium
838 sco5-cc.
839 [Ben Laurie]
840
841 *) Eliminate generated files from CVS. Reorder tests to regenerate files
842 before they are needed.
843 [Ben Laurie]
844
845 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
846 [Ben Laurie]
847
848 Changes between 0.9.1b and 0.9.1c
849
850 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
851 changed SSLeay to OpenSSL in version strings.
852 [Ralf S. Engelschall]
853
854 *) Some fixups to the top-level documents.
855 [Paul Sutton]
856
857 *) Fixed the nasty bug where rsaref.h was not found under compile-time
858 because the symlink to include/ was missing.
859 [Ralf S. Engelschall]
860
861 *) Incorporated the popular no-RSA/DSA-only patches
862 which allow to compile a RSA-free SSLeay.
863 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
864
865 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
866 when "ssleay" is still not found.
867 [Ralf S. Engelschall]
868
869 *) Added more platforms to Configure: Cray T3E, HPUX 11,
870 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
871
872 *) Updated the README file.
873 [Ralf S. Engelschall]
874
875 *) Added various .cvsignore files in the CVS repository subdirs
876 to make a "cvs update" really silent.
877 [Ralf S. Engelschall]
878
879 *) Recompiled the error-definition header files and added
880 missing symbols to the Win32 linker tables.
881 [Ralf S. Engelschall]
882
883 *) Cleaned up the top-level documents;
884 o new files: CHANGES and LICENSE
885 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
886 o merged COPYRIGHT into LICENSE
887 o removed obsolete TODO file
888 o renamed MICROSOFT to INSTALL.W32
889 [Ralf S. Engelschall]
890
891 *) Removed dummy files from the 0.9.1b source tree:
892 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
893 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
894 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
895 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
896 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
897 [Ralf S. Engelschall]
898
899 *) Added various platform portability fixes.
900 [Mark J. Cox]
901
902 *) The Genesis of the OpenSSL rpject:
903 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
904 Young and Tim J. Hudson created while they were working for C2Net until
905 summer 1998.
906 [The OpenSSL Project]
907
908 Changes between 0.9.0b and 0.9.1b
909
910 *) Updated a few CA certificates under certs/
911 [Eric A. Young]
912
913 *) Changed some BIGNUM api stuff.
914 [Eric A. Young]
915
916 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
917 DGUX x86, Linux Alpha, etc.
918 [Eric A. Young]
919
920 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
921 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
922 available).
923 [Eric A. Young]
924
925 *) Add -strparse option to asn1pars program which parses nested
926 binary structures
927 [Dr Stephen Henson <shenson@bigfoot.com>]
928
929 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
930 [Eric A. Young]
931
932 *) DSA fix for "ca" program.
933 [Eric A. Young]
934
935 *) Added "-genkey" option to "dsaparam" program.
936 [Eric A. Young]
937
938 *) Added RIPE MD160 (rmd160) message digest.
939 [Eric A. Young]
940
941 *) Added -a (all) option to "ssleay version" command.
942 [Eric A. Young]
943
944 *) Added PLATFORM define which is the id given to Configure.
945 [Eric A. Young]
946
947 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
948 [Eric A. Young]
949
950 *) Extended the ASN.1 parser routines.
951 [Eric A. Young]
952
953 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
954 [Eric A. Young]
955
956 *) Added a BN_CTX to the BN library.
957 [Eric A. Young]
958
959 *) Fixed the weak key values in DES library
960 [Eric A. Young]
961
962 *) Changed API in EVP library for cipher aliases.
963 [Eric A. Young]
964
965 *) Added support for RC2/64bit cipher.
966 [Eric A. Young]
967
968 *) Converted the lhash library to the crypto/mem.c functions.
969 [Eric A. Young]
970
971 *) Added more recognized ASN.1 object ids.
972 [Eric A. Young]
973
974 *) Added more RSA padding checks for SSL/TLS.
975 [Eric A. Young]
976
977 *) Added BIO proxy/filter functionality.
978 [Eric A. Young]
979
980 *) Added extra_certs to SSL_CTX which can be used
981 send extra CA certificates to the client in the CA cert chain sending
982 process. It can be configured with SSL_CTX_add_extra_chain_cert().
983 [Eric A. Young]
984
985 *) Now Fortezza is denied in the authentication phase because
986 this is key exchange mechanism is not supported by SSLeay at all.
987 [Eric A. Young]
988
989 *) Additional PKCS1 checks.
990 [Eric A. Young]
991
992 *) Support the string "TLSv1" for all TLS v1 ciphers.
993 [Eric A. Young]
994
995 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
996 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
997 [Eric A. Young]
998
999 *) Fixed a few memory leaks.
1000 [Eric A. Young]
1001
1002 *) Fixed various code and comment typos.
1003 [Eric A. Young]
1004
1005 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1006 bytes sent in the client random.
1007 [Edward Bishop <ebishop@spyglass.com>]
1008
