6 Changes between 0.9.2b and 0.9.3
7
8 *) Support INSTALL_PREFIX for package builders, as proposed by
9 David Harris.
10 [Bodo Moeller]
11
12 *) New Configure options "threads" and "no-threads". For systems
13 where the proper compiler options are known (currently Solaris
14 and Linux), "threads" is the default.
15 [Bodo Moeller]
16
17 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
18 [Bodo Moeller]
19
20 *) Install various scripts to $(OPENSSLDIR)/misc, not to
21 $(INSTALLTOP)/bin -- they shouldn't clutter directories
22 such as /usr/local/bin.
23 [Bodo Moeller]
24
25 *) "make linux-shared" to build shared libraries.
26 [Niels Poppe <niels@netbox.org>]
27
28 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
29 [Ulf Möller]
30
31 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
32 extension adding in x509 utility.
33 [Steve Henson]
34
35 *) Remove NOPROTO sections and error code comments.
36 [Ulf Möller]
37
38 *) Partial rewrite of the DEF file generator to now parse the ANSI
39 prototypes.
40 [Steve Henson]
41
42 *) New Configure options --prefix=DIR and --openssldir=DIR.
43 [Ulf Möller]
44
45 *) Complete rewrite of the error code script(s). It is all now handled
46 by one script at the top level which handles error code gathering,
47 header rewriting and C source file generation. It should be much better
48 than the old method: it now uses a modified version of Ulf's parser to
49 read the ANSI prototypes in all header files (thus the old K&R definitions
50 aren't needed for error creation any more) and do a better job of
51 translating function codes into names. The old 'ASN1 error code imbedded
52 in a comment' is no longer necessary and it doesn't use .err files which
53 have now been deleted. Also the error code call doesn't have to appear all
54 on one line (which resulted in some large lines...).
55 [Steve Henson]
56
57 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
58 [Bodo Moeller]
59
60 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
61 0 (which usually indicates a closed connection), but continue reading.
62 [Bodo Moeller]
63
64 *) Fix some race conditions.
65 [Bodo Moeller]
66
67 *) Add support for CRL distribution points extension. Add Certificate
68 Policies and CRL distribution points documentation.
69 [Steve Henson]
70
71 *) Move the autogenerated header file parts to crypto/opensslconf.h.
72 [Ulf Möller]
73
74 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
75 8 of keying material. Merlin has also confirmed interop with this fix
76 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
77 [Merlin Hughes <merlin@baltimore.ie>]
78
79 *) Fix lots of warnings.
80 [Richard Levitte <levitte@stacken.kth.se>]
81
82 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
83 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
84 [Richard Levitte <levitte@stacken.kth.se>]
85
86 *) Fix problems with sizeof(long) == 8.
87 [Andy Polyakov <appro@fy.chalmers.se>]
88
89 *) Change functions to ANSI C.
90 [Ulf Möller]
91
92 *) Fix typos in error codes.
93 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
94
95 *) Remove defunct assembler files from Configure.
96 [Ulf Möller]
97
98 *) SPARC v8 assembler BIGNUM implementation.
99 [Andy Polyakov <appro@fy.chalmers.se>]
100
101 *) Support for Certificate Policies extension: both print and set.
102 Various additions to support the r2i method this uses.
103 [Steve Henson]
104
105 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
106 return a const string when you are expecting an allocated buffer.
107 [Ben Laurie]
108
109 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
110 types DirectoryString and DisplayText.
111 [Steve Henson]
112
113 *) Add code to allow r2i extensions to access the configuration database,
114 add an LHASH database driver and add several ctx helper functions.
115 [Steve Henson]
116
117 *) Fix an evil bug in bn_expand2() which caused various BN functions to
118 fail when they extended the size of a BIGNUM.
119 [Steve Henson]
120
121 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
122 support typesafe stack.
123 [Steve Henson]
124
125 *) Fix typo in SSL_[gs]et_options().
126 [Nils Frostberg <nils@medcom.se>]
127
128 *) Delete various functions and files that belonged to the (now obsolete)
129 old X509V3 handling code.
130 [Steve Henson]
131
132 *) New Configure option "rsaref".
133 [Ulf Möller]
134
135 *) Don't auto-generate pem.h.
136 [Bodo Moeller]
137
138 *) Introduce type-safe ASN.1 SETs.
139 [Ben Laurie]
140
141 *) Introduce type-safe STACKs. This will almost certainly break lots of code
142 that links with OpenSSL (well at least cause lots of warnings), but fear
143 not: the conversion is trivial, and it eliminates loads of evil casts. A
144 few STACKed things have been converted already. Feel free to convert more.
145 In the fullness of time, I'll do away with the STACK type altogether.
146 [Ben Laurie]
147
148 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
149 specified in <certfile> by updating the entry in the index.txt file.
150 This way one no longer has to edit the index.txt file manually for
151 revoking a certificate. The -revoke option does the gory details now.
152 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
153
154 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
155 `-text' option at all and this way the `-noout -text' combination was
156 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
157 [Ralf S. Engelschall]
158
159 *) Make sure a corresponding plain text error message exists for the
160 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
161 verify callback function determined that a certificate was revoked.
162 [Ralf S. Engelschall]
163
164 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
165 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
166 all available cipers including rc5, which was forgotten until now.
167 In order to let the testing shell script know which algorithms
168 are available, a new (up to now undocumented) command
169 "openssl list-cipher-commands" is used.
170 [Bodo Moeller]
171
172 *) Bugfix: s_client occasionally would sleep in select() when
173 it should have checked SSL_pending() first.
174 [Bodo Moeller]
175
176 *) New functions DSA_do_sign and DSA_do_verify to provide access to
177 the raw DSA values prior to ASN.1 encoding.
178 [Ulf Möller]
179
180 *) Tweaks to Configure
181 Niels Poppe <niels@netbox.org>
182
183 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
184 yet...
185 [Steve Henson]
186
187 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
188 [Ulf Möller]
189
190 *) New config option to avoid instructions that are illegal on the 80386.
191 The default code is faster, but requires at least a 486.
192 [Ulf Möller]
193
194 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
195 SSL2_SERVER_VERSION (not used at all) macros, which are now the
196 same as SSL2_VERSION anyway.
197 [Bodo Moeller]
198
199 *) New "-showcerts" option for s_client.
200 [Bodo Moeller]
201
202 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
203 application. Various cleanups and fixes.
204 [Steve Henson]
205
206 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
207 modify error routines to work internally. Add error codes and PBE init
208 to library startup routines.
209 [Steve Henson]
210
211 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
212 packing functions to asn1 and evp. Changed function names and error
213 codes along the way.
214 [Steve Henson]
215
216 *) PKCS12 integration: and so it begins... First of several patches to
217 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
218 objects to objects.h
219 [Steve Henson]
220
221 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
222 and display support for Thawte strong extranet extension.
223 [Steve Henson]
224
225 *) Add LinuxPPC support.
226 [Jeff Dubrule <igor@pobox.org>]
227
228 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
229 bn_div_words in alpha.s.
230 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
231
232 *) Make sure the RSA OAEP test is skipped under -DRSAref because
233 OAEP isn't supported when OpenSSL is built with RSAref.
234 [Ulf Moeller <ulf@fitug.de>]
235
236 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
237 so they no longer are missing under -DNOPROTO.
238 [Soren S. Jorvang <soren@t.dk>]
239
240 Changes between 0.9.1c and 0.9.2b
241
242 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
243 doesn't work when the session is reused. Coming soon!
244 [Ben Laurie]
245
246 *) Fix a security hole, that allows sessions to be reused in the wrong
247 context thus bypassing client cert protection! All software that uses
248 client certs and session caches in multiple contexts NEEDS PATCHING to
249 allow session reuse! A fuller solution is in the works.
250 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
251
252 *) Some more source tree cleanups (removed obsolete files
253 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
254 permission on "config" script to be executable) and a fix for the INSTALL
255 document.
256 [Ulf Moeller <ulf@fitug.de>]
257
258 *) Remove some legacy and erroneous uses of malloc, free instead of
259 Malloc, Free.
260 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
261
262 *) Make rsa_oaep_test return non-zero on error.
263 [Ulf Moeller <ulf@fitug.de>]
264
265 *) Add support for native Solaris shared libraries. Configure
266 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
267 if someone would make that last step automatic.
268 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
269
270 *) ctx_size was not built with the right compiler during "make links". Fixed.
271 [Ben Laurie]
272
273 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
274 except NULL ciphers". This means the default cipher list will no longer
275 enable NULL ciphers. They need to be specifically enabled e.g. with
276 the string "DEFAULT:eNULL".
277 [Steve Henson]
278
279 *) Fix to RSA private encryption routines: if p < q then it would
280 occasionally produce an invalid result. This will only happen with
281 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
282 [Steve Henson]
283
284 *) Be less restrictive and allow also `perl util/perlpath.pl
285 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
286 because this way one can also use an interpreter named `perl5' (which is
287 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
288 installed as `perl').
289 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
290
291 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
292 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
293
294 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
295 advapi32.lib to Win32 build and change the pem test comparision
296 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
297 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
298 and crypto/des/ede_cbcm_enc.c.
299 [Steve Henson]
300
301 *) DES quad checksum was broken on big-endian architectures. Fixed.
302 [Ben Laurie]
303
304 *) Comment out two functions in bio.h that aren't implemented. Fix up the
305 Win32 test batch file so it (might) work again. The Win32 test batch file
306 is horrible: I feel ill....
307 [Steve Henson]
308
309 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
310 in e_os.h. Audit of header files to check ANSI and non ANSI
311 sections: 10 functions were absent from non ANSI section and not exported
312 from Windows DLLs. Fixed up libeay.num for new functions.
313 [Steve Henson]
314
315 *) Make `openssl version' output lines consistent.
316 [Ralf S. Engelschall]
317
318 *) Fix Win32 symbol export lists for BIO functions: Added
319 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
320 to ms/libeay{16,32}.def.
321 [Ralf S. Engelschall]
322
323 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
324 fine under Unix and passes some trivial tests I've now added. But the
325 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
326 added to make sure no one expects that this stuff really works in the
327 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
328 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
329 openssl_bio.xs.
330 [Ralf S. Engelschall]
331
332 *) Fix the generation of two part addresses in perl.
333 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
334
335 *) Add config entry for Linux on MIPS.
336 [John Tobey <jtobey@channel1.com>]
337
338 *) Make links whenever Configure is run, unless we are on Windoze.
339 [Ben Laurie]
340
341 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
342 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
343 in CRLs.
344 [Steve Henson]
345
346 *) Add a useful kludge to allow package maintainers to specify compiler and
347 other platforms details on the command line without having to patch the
348 Configure script everytime: One now can use ``perl Configure
349 <id>:<details>'', i.e. platform ids are allowed to have details appended
350 to them (seperated by colons). This is treated as there would be a static
351 pre-configured entry in Configure's %table under key <id> with value
352 <details> and ``perl Configure <id>'' is called. So, when you want to
353 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
354 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
355 now, which overrides the FreeBSD-elf entry on-the-fly.
356 [Ralf S. Engelschall]
357
358 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
359 [Ben Laurie]
360
361 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
362 on the `perl Configure ...' command line. This way one can compile
363 OpenSSL libraries with Position Independent Code (PIC) which is needed
364 for linking it into DSOs.
365 [Ralf S. Engelschall]
366
367 *) Remarkably, export ciphers were totally broken and no-one had noticed!
368 Fixed.
369 [Ben Laurie]
370
371 *) Cleaned up the LICENSE document: The official contact for any license
372 questions now is the OpenSSL core team under openssl-core@openssl.org.
373 And add a paragraph about the dual-license situation to make sure people
374 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
375 to the OpenSSL toolkit.
376 [Ralf S. Engelschall]
377
378 *) General source tree makefile cleanups: Made `making xxx in yyy...'
379 display consistent in the source tree and replaced `/bin/rm' by `rm'.
380 Additonally cleaned up the `make links' target: Remove unnecessary
381 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
382 to speed processing and no longer clutter the display with confusing
383 stuff. Instead only the actually done links are displayed.
384 [Ralf S. Engelschall]
385
386 *) Permit null encryption ciphersuites, used for authentication only. It used
387 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
388 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
389 encryption.
390 [Ben Laurie]
391
392 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
393 signed attributes when verifying signatures (this would break them),
394 the detached data encoding was wrong and public keys obtained using
395 X509_get_pubkey() weren't freed.
396 [Steve Henson]
397
398 *) Add text documentation for the BUFFER functions. Also added a work around
399 to a Win95 console bug. This was triggered by the password read stuff: the
400 last character typed gets carried over to the next fread(). If you were
401 generating a new cert request using 'req' for example then the last
402 character of the passphrase would be CR which would then enter the first
403 field as blank.
404 [Steve Henson]
405
406 *) Added the new `Includes OpenSSL Cryptography Software' button as
407 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
408 button and can be used by applications based on OpenSSL to show the
409 relationship to the OpenSSL project.
410 [Ralf S. Engelschall]
411
412 *) Remove confusing variables in function signatures in files
413 ssl/ssl_lib.c and ssl/ssl.h.
414 [Lennart Bong <lob@kulthea.stacken.kth.se>]
415
416 *) Don't install bss_file.c under PREFIX/include/
417 [Lennart Bong <lob@kulthea.stacken.kth.se>]
418
419 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
420 functions that return function pointers and has support for NT specific
421 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
422 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
423 unsigned to signed types: this was killing the Win32 compile.
424 [Steve Henson]
425
426 *) Add new certificate file to stack functions,
427 SSL_add_dir_cert_subjects_to_stack() and
428 SSL_add_file_cert_subjects_to_stack(). These largely supplant
429 SSL_load_client_CA_file(), and can be used to add multiple certs easily
430 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
431 This means that Apache-SSL and similar packages don't have to mess around
432 to add as many CAs as they want to the preferred list.
433 [Ben Laurie]
434
435 *) Experiment with doxygen documentation. Currently only partially applied to
436 ssl/ssl_lib.c.
437 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
438 openssl.doxy as the configuration file.
439 [Ben Laurie]
440
441 *) Get rid of remaining C++-style comments which strict C compilers hate.
442 [Ralf S. Engelschall, pointed out by Carlos Amengual]
443
444 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
445 compiled in by default: it has problems with large keys.
446 [Steve Henson]
447
448 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
449 DH private keys and/or callback functions which directly correspond to
450 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
451 is needed for applications which have to configure certificates on a
452 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
453 (e.g. s_server).
454 For the RSA certificate situation is makes no difference, but
455 for the DSA certificate situation this fixes the "no shared cipher"
456 problem where the OpenSSL cipher selection procedure failed because the
457 temporary keys were not overtaken from the context and the API provided
458 no way to reconfigure them.
459 The new functions now let applications reconfigure the stuff and they
460 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
461 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
462 non-public-API function ssl_cert_instantiate() is used as a helper
463 function and also to reduce code redundancy inside ssl_rsa.c.
464 [Ralf S. Engelschall]
465
466 *) Move s_server -dcert and -dkey options out of the undocumented feature
467 area because they are useful for the DSA situation and should be
468 recognized by the users.
469 [Ralf S. Engelschall]
470
471 *) Fix the cipher decision scheme for export ciphers: the export bits are
472 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
473 SSL_EXP_MASK. So, the original variable has to be used instead of the
474 already masked variable.
475 [Richard Levitte <levitte@stacken.kth.se>]
476
477 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
478 [Richard Levitte <levitte@stacken.kth.se>]
479
480 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
481 from `int' to `unsigned int' because it's a length and initialized by
482 EVP_DigestFinal() which expects an `unsigned int *'.
483 [Richard Levitte <levitte@stacken.kth.se>]
484
485 *) Don't hard-code path to Perl interpreter on shebang line of Configure
486 script. Instead use the usual Shell->Perl transition trick.
487 [Ralf S. Engelschall]
488
489 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
490 (in addition to RSA certificates) to match the behaviour of `openssl dsa
491 -noout -modulus' as it's already the case for `openssl rsa -noout
492 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
493 currently the public key is printed (a decision which was already done by
494 `openssl dsa -modulus' in the past) which serves a similar purpose.
495 Additionally the NO_RSA no longer completely removes the whole -modulus
496 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
497 now, too.
498 [Ralf S. Engelschall]
499
500 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
501 BIO. See the source (crypto/evp/bio_ok.c) for more info.
502 [Arne Ansper <arne@ats.cyber.ee>]
503
504 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
505 to be added. Now both 'req' and 'ca' can use new objects defined in the
506 config file.
507 [Steve Henson]
508
509 *) Add cool BIO that does syslog (or event log on NT).
510 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
511
512 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
513 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
514 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
515 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
516 [Ben Laurie]
517
518 *) Add preliminary config info for new extension code.
519 [Steve Henson]
520
521 *) Make RSA_NO_PADDING really use no padding.
522 [Ulf Moeller <ulf@fitug.de>]
523
524 *) Generate errors when private/public key check is done.
525 [Ben Laurie]
526
527 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
528 for some CRL extensions and new objects added.
529 [Steve Henson]
530
531 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
532 key usage extension and fuller support for authority key id.
533 [Steve Henson]
534
535 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
536 padding method for RSA, which is recommended for new applications in PKCS
537 #1 v2.0 (RFC 2437, October 1998).
538 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
539 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
540 against Bleichbacher's attack on RSA.
541 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
542 Ben Laurie]
543
544 *) Updates to the new SSL compression code
545 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
546
547 *) Fix so that the version number in the master secret, when passed
548 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
549 (because the server will not accept higher), that the version number
550 is 0x03,0x01, not 0x03,0x00
551 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
552
553 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
554 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
555 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
556 [Steve Henson]
557
558 *) Support for RAW extensions where an arbitrary extension can be
559 created by including its DER encoding. See apps/openssl.cnf for
560 an example.
561 [Steve Henson]
562
563 *) Make sure latest Perl versions don't interpret some generated C array
564 code as Perl array code in the crypto/err/err_genc.pl script.
565 [Lars Weber <3weber@informatik.uni-hamburg.de>]
566
567 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
568 not many people have the assembler. Various Win32 compilation fixes and
569 update to the INSTALL.W32 file with (hopefully) more accurate Win32
570 build instructions.
571 [Steve Henson]
572
573 *) Modify configure script 'Configure' to automatically create crypto/date.h
574 file under Win32 and also build pem.h from pem.org. New script
575 util/mkfiles.pl to create the MINFO file on environments that can't do a
576 'make files': perl util/mkfiles.pl >MINFO should work.
577 [Steve Henson]
578
579 *) Major rework of DES function declarations, in the pursuit of correctness
580 and purity. As a result, many evil casts evaporated, and some weirdness,
581 too. You may find this causes warnings in your code. Zapping your evil
582 casts will probably fix them. Mostly.
583 [Ben Laurie]
584
585 *) Fix for a typo in asn1.h. Bug fix to object creation script
586 obj_dat.pl. It considered a zero in an object definition to mean
587 "end of object": none of the objects in objects.h have any zeros
588 so it wasn't spotted.
589 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
590
591 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
592 Masking (CBCM). In the absence of test vectors, the best I have been able
593 to do is check that the decrypt undoes the encrypt, so far. Send me test
594 vectors if you have them.
595 [Ben Laurie]
596
597 *) Correct calculation of key length for export ciphers (too much space was
598 allocated for null ciphers). This has not been tested!
599 [Ben Laurie]
600
601 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
602 message is now correct (it understands "crypto" and "ssl" on its
603 command line). There is also now an "update" option. This will update
604 the util/ssleay.num and util/libeay.num files with any new functions.
605 If you do a:
606 perl util/mkdef.pl crypto ssl update
607 it will update them.
608 [Steve Henson]
609
610 *) Overhauled the Perl interface (perl/*):
611 - ported BN stuff to OpenSSL's different BN library
612 - made the perl/ source tree CVS-aware
613 - renamed the package from SSLeay to OpenSSL (the files still contain
614 their history because I've copied them in the repository)
615 - removed obsolete files (the test scripts will be replaced
616 by better Test::Harness variants in the future)
617 [Ralf S. Engelschall]
618
619 *) First cut for a very conservative source tree cleanup:
620 1. merge various obsolete readme texts into doc/ssleay.txt
621 where we collect the old documents and readme texts.
622 2. remove the first part of files where I'm already sure that we no
623 longer need them because of three reasons: either they are just temporary
624 files which were left by Eric or they are preserved original files where
625 I've verified that the diff is also available in the CVS via "cvs diff
626 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
627 the crypto/md/ stuff).
628 [Ralf S. Engelschall]
629
630 *) More extension code. Incomplete support for subject and issuer alt
631 name, issuer and authority key id. Change the i2v function parameters
632 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
633 what that's for :-) Fix to ASN1 macro which messed up
634 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
635 [Steve Henson]
636
637 *) Preliminary support for ENUMERATED type. This is largely copied from the
638 INTEGER code.
639 [Steve Henson]
640
641 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
642 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
643
644 *) Make sure `make rehash' target really finds the `openssl' program.
645 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
646
647 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
648 like to hear about it if this slows down other processors.
649 [Ben Laurie]
650
651 *) Add CygWin32 platform information to Configure script.
652 [Alan Batie <batie@aahz.jf.intel.com>]
653
654 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
655 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
656
657 *) New program nseq to manipulate netscape certificate sequences
658 [Steve Henson]
659
660 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
661 few typos.
662 [Steve Henson]
663
664 *) Fixes to BN code. Previously the default was to define BN_RECURSION
665 but the BN code had some problems that would cause failures when
666 doing certificate verification and some other functions.
667 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
668
669 *) Add ASN1 and PEM code to support netscape certificate sequences.
670 [Steve Henson]
671
672 *) Add ASN1 and PEM code to support netscape certificate sequences.
673 [Steve Henson]
674
675 *) Add several PKIX and private extended key usage OIDs.
676 [Steve Henson]
677
678 *) Modify the 'ca' program to handle the new extension code. Modify
679 openssl.cnf for new extension format, add comments.
680 [Steve Henson]
681
682 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
683 and add a sample to openssl.cnf so req -x509 now adds appropriate
684 CA extensions.
685 [Steve Henson]
686
687 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
688 error code, add initial support to X509_print() and x509 application.
689 [Steve Henson]
690
691 *) Takes a deep breath and start addding X509 V3 extension support code. Add
692 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
693 stuff is currently isolated and isn't even compiled yet.
694 [Steve Henson]
695
696 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
697 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
698 Removed the versions check from X509 routines when loading extensions:
699 this allows certain broken certificates that don't set the version
700 properly to be processed.
701 [Steve Henson]
702
703 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
704 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
705 can still be regenerated with "make depend".
706 [Ben Laurie]
707
708 *) Spelling mistake in C version of CAST-128.
709 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
710
711 *) Changes to the error generation code. The perl script err-code.pl
712 now reads in the old error codes and retains the old numbers, only
713 adding new ones if necessary. It also only changes the .err files if new
714 codes are added. The makefiles have been modified to only insert errors
715 when needed (to avoid needlessly modifying header files). This is done
716 by only inserting errors if the .err file is newer than the auto generated
717 C file. To rebuild all the error codes from scratch (the old behaviour)
718 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
719 or delete all the .err files.
720 [Steve Henson]
721
722 *) CAST-128 was incorrectly implemented for short keys. The C version has
723 been fixed, but is untested. The assembler versions are also fixed, but
724 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
725 to regenerate it if needed.
726 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
727 Hagino <itojun@kame.net>]
728
729 *) File was opened incorrectly in randfile.c.
730 [Ulf Möller <ulf@fitug.de>]
731
732 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
733 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
734 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
735 al: it's just almost always a UTCTime. Note this patch adds new error
736 codes so do a "make errors" if there are problems.
737 [Steve Henson]
738
739 *) Correct Linux 1 recognition in config.
740 [Ulf Möller <ulf@fitug.de>]
741
742 *) Remove pointless MD5 hash when using DSA keys in ca.
743 [Anonymous <nobody@replay.com>]
744
745 *) Generate an error if given an empty string as a cert directory. Also
746 generate an error if handed NULL (previously returned 0 to indicate an
747 error, but didn't set one).
748 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
749
750 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
751 [Ben Laurie]
752
753 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
754 parameters. This was causing a warning which killed off the Win32 compile.
755 [Steve Henson]
756
757 *) Remove C++ style comments from crypto/bn/bn_local.h.
758 [Neil Costigan <neil.costigan@celocom.com>]
759
760 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
761 based on a text string, looking up short and long names and finally
762 "dot" format. The "dot" format stuff didn't work. Added new function
763 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
764 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
765 OID is not part of the table.
766 [Steve Henson]
767
768 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
769 X509_LOOKUP_by_alias().
770 [Ben Laurie]
771
772 *) Sort openssl functions by name.
773 [Ben Laurie]
774
775 *) Get the gendsa program working (hopefully) and add it to app list. Remove
776 encryption from sample DSA keys (in case anyone is interested the password
777 was "1234").
778 [Steve Henson]
779
780 *) Make _all_ *_free functions accept a NULL pointer.
781 [Frans Heymans <fheymans@isaserver.be>]
782
783 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
784 NULL pointers.
785 [Anonymous <nobody@replay.com>]
786
787 *) s_server should send the CAfile as acceptable CAs, not its own cert.
788 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
789
790 *) Don't blow it for numeric -newkey arguments to apps/req.
791 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
792
793 *) Temp key "for export" tests were wrong in s3_srvr.c.
794 [Anonymous <nobody@replay.com>]
795
796 *) Add prototype for temp key callback functions
797 SSL_CTX_set_tmp_{rsa,dh}_callback().
798 [Ben Laurie]
799
800 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
801 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
802 [Steve Henson]
803
804 *) X509_name_add_entry() freed the wrong thing after an error.
805 [Arne Ansper <arne@ats.cyber.ee>]
806
807 *) rsa_eay.c would attempt to free a NULL context.
808 [Arne Ansper <arne@ats.cyber.ee>]
809
810 *) BIO_s_socket() had a broken should_retry() on Windoze.
811 [Arne Ansper <arne@ats.cyber.ee>]
812
813 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
814 [Arne Ansper <arne@ats.cyber.ee>]
815
816 *) Make sure the already existing X509_STORE->depth variable is initialized
817 in X509_STORE_new(), but document the fact that this variable is still
818 unused in the certificate verification process.
819 [Ralf S. Engelschall]
820
821 *) Fix the various library and apps files to free up pkeys obtained from
822 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
823 [Steve Henson]
824
825 *) Fix reference counting in X509_PUBKEY_get(). This makes
826 demos/maurice/example2.c work, amongst others, probably.
827 [Steve Henson and Ben Laurie]
828
829 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
830 `openssl' and second, the shortcut symlinks for the `openssl <command>'
831 are no longer created. This way we have a single and consistent command
832 line interface `openssl <command>', similar to `cvs <command>'.
833 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
834
835 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
836 BIT STRING wrapper always have zero unused bits.
837 [Steve Henson]
838
839 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
840 [Steve Henson]
841
842 *) Make the top-level INSTALL documentation easier to understand.
843 [Paul Sutton]
844
845 *) Makefiles updated to exit if an error occurs in a sub-directory
846 make (including if user presses ^C) [Paul Sutton]
847
848 *) Make Montgomery context stuff explicit in RSA data structure.
849 [Ben Laurie]
850
851 *) Fix build order of pem and err to allow for generated pem.h.
852 [Ben Laurie]
853
854 *) Fix renumbering bug in X509_NAME_delete_entry().
855 [Ben Laurie]
856
857 *) Enhanced the err-ins.pl script so it makes the error library number
858 global and can add a library name. This is needed for external ASN1 and
859 other error libraries.
860 [Steve Henson]
861
862 *) Fixed sk_insert which never worked properly.
863 [Steve Henson]
864
865 *) Fix ASN1 macros so they can handle indefinite length construted
866 EXPLICIT tags. Some non standard certificates use these: they can now
867 be read in.
868 [Steve Henson]
869
870 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
871 into a single doc/ssleay.txt bundle. This way the information is still
872 preserved but no longer messes up this directory. Now it's new room for
873 the new set of documenation files.
874 [Ralf S. Engelschall]
875
876 *) SETs were incorrectly DER encoded. This was a major pain, because they
877 shared code with SEQUENCEs, which aren't coded the same. This means that
878 almost everything to do with SETs or SEQUENCEs has either changed name or
879 number of arguments.
880 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
881
882 *) Fix test data to work with the above.
883 [Ben Laurie]
884
885 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
886 was already fixed by Eric for 0.9.1 it seems.
887 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
888
889 *) Autodetect FreeBSD3.
890 [Ben Laurie]
891
892 *) Fix various bugs in Configure. This affects the following platforms:
893 nextstep
894 ncr-scde
895 unixware-2.0
896 unixware-2.0-pentium
897 sco5-cc.
898 [Ben Laurie]
899
900 *) Eliminate generated files from CVS. Reorder tests to regenerate files
901 before they are needed.
902 [Ben Laurie]
903
904 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
905 [Ben Laurie]
906
907 Changes between 0.9.1b and 0.9.1c
908
909 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
910 changed SSLeay to OpenSSL in version strings.
911 [Ralf S. Engelschall]
912
913 *) Some fixups to the top-level documents.
914 [Paul Sutton]
915
916 *) Fixed the nasty bug where rsaref.h was not found under compile-time
917 because the symlink to include/ was missing.
918 [Ralf S. Engelschall]
919
920 *) Incorporated the popular no-RSA/DSA-only patches
921 which allow to compile a RSA-free SSLeay.
922 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
923
924 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
925 when "ssleay" is still not found.
926 [Ralf S. Engelschall]
927
928 *) Added more platforms to Configure: Cray T3E, HPUX 11,
929 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
930
931 *) Updated the README file.
932 [Ralf S. Engelschall]
933
934 *) Added various .cvsignore files in the CVS repository subdirs
935 to make a "cvs update" really silent.
936 [Ralf S. Engelschall]
937
938 *) Recompiled the error-definition header files and added
939 missing symbols to the Win32 linker tables.
940 [Ralf S. Engelschall]
941
942 *) Cleaned up the top-level documents;
943 o new files: CHANGES and LICENSE
944 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
945 o merged COPYRIGHT into LICENSE
946 o removed obsolete TODO file
947 o renamed MICROSOFT to INSTALL.W32
948 [Ralf S. Engelschall]
949
950 *) Removed dummy files from the 0.9.1b source tree:
951 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
952 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
953 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
954 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
955 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
956 [Ralf S. Engelschall]
957
958 *) Added various platform portability fixes.
959 [Mark J. Cox]
960
961 *) The Genesis of the OpenSSL rpject:
962 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
963 Young and Tim J. Hudson created while they were working for C2Net until
964 summer 1998.
965 [The OpenSSL Project]
966
967 Changes between 0.9.0b and 0.9.1b
968
969 *) Updated a few CA certificates under certs/
970 [Eric A. Young]
971
972 *) Changed some BIGNUM api stuff.
973 [Eric A. Young]
974
975 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
976 DGUX x86, Linux Alpha, etc.
977 [Eric A. Young]
978
979 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
980 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
981 available).
982 [Eric A. Young]
983
984 *) Add -strparse option to asn1pars program which parses nested
985 binary structures
986 [Dr Stephen Henson <shenson@bigfoot.com>]
987
988 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
989 [Eric A. Young]
990
991 *) DSA fix for "ca" program.
992 [Eric A. Young]
993
994 *) Added "-genkey" option to "dsaparam" program.
995 [Eric A. Young]
996
997 *) Added RIPE MD160 (rmd160) message digest.
998 [Eric A. Young]
999
1000 *) Added -a (all) option to "ssleay version" command.
1001 [Eric A. Young]
1002
1003 *) Added PLATFORM define which is the id given to Configure.
1004 [Eric A. Young]
1005
1006 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1007 [Eric A. Young]
1008
1009 *) Extended the ASN.1 parser routines.
1010 [Eric A. Young]
1011
1012 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1013 [Eric A. Young]
1014
1015 *) Added a BN_CTX to the BN library.
1016 [Eric A. Young]
1017
1018 *) Fixed the weak key values in DES library
1019 [Eric A. Young]
1020
1021 *) Changed API in EVP library for cipher aliases.
1022 [Eric A. Young]
1023
1024 *) Added support for RC2/64bit cipher.
1025 [Eric A. Young]
1026
1027 *) Converted the lhash library to the crypto/mem.c functions.
1028 [Eric A. Young]
1029
1030 *) Added more recognized ASN.1 object ids.
1031 [Eric A. Young]
1032
1033 *) Added more RSA padding checks for SSL/TLS.
1034 [Eric A. Young]
1035
