6 Changes between 0.9.2b and 0.9.3 [XX May 1999]
7 [I suggest using the same format for the
8 date as in opensslv.h. 0.9.1c used
9 hyphens in the date, so I wrote
10 [23-Dec-1998] down below; but in later
11 versions, these hyphens are gone.]
13 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
14 correctly handle encrypted S/MIME data.
17 *) Change type of various DES function arguments from des_cblock
18 (which means, in function argument declarations, pointer to char)
19 to des_cblock * (meaning pointer to array with 8 char elements),
20 which allows the compiler to do more typechecking; it was like
21 that back in SSLeay, but with lots of ugly casts.
23 Introduce new type const_des_cblock.
26 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
27 problems: find RecipientInfo structure that matches recipient certificate
28 and initialise the ASN1 structures properly based on passed cipher.
31 *) Belatedly make the BN tests actually check the results.
34 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
35 to and from BNs: it was completely broken. New compilation option
36 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
37 key elements as negative integers.
40 *) Reorganize and speed up MD5.
41 [Andy Polyakov <appro@fy.chalmers.se>]
44 [Richard Levitte <richard@levitte.org>]
46 *) New option -out to asn1parse to allow the parsed structure to be
47 output to a file. This is most useful when combined with the -strparse
48 option to examine the output of things like OCTET STRINGS.
51 *) Make SSL library a little more fool-proof by not requiring any longer
52 that SSL_set_{accept,connect}_state be called before
53 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
54 in many applications because usually everything *appeared* to work as
55 intended anyway -- now it really works as intended).
58 *) Move openssl.cnf out of lib/.
61 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
62 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
63 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
66 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
67 handle PKCS#7 enveloped data properly.
68 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
70 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
71 copying pointers. The cert_st handling is changed by this in
72 various ways (and thus what used to be known as ctx->default_cert
73 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
74 any longer when s->cert does not give us what we need).
75 ssl_cert_instantiate becomes obsolete by this change.
76 As soon as we've got the new code right (possibly it already is?),
77 we have solved a couple of bugs of the earlier code where s->cert
78 was used as if it could not have been shared with other SSL structures.
80 Note that using the SSL API in certain dirty ways now will result
81 in different behaviour than observed with earlier library versions:
82 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
83 does not influence s as it used to.
85 In order to clean up things more thoroughly, inside SSL_SESSION
86 we don't use CERT any longer, but a new structure SESS_CERT
87 that holds per-session data (if available); currently, this is
88 the peer's certificate chain and, for clients, the server's certificate
89 and temporary key. CERT holds only those values that can have
90 meaningful defaults in an SSL_CTX.
93 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
94 from the internal representation. Various PKCS#7 fixes: remove some
95 evil casts and set the enc_dig_alg field properly based on the signing
99 *) Allow PKCS#12 password to be set from the command line or the
100 environment. Let 'ca' get its config file name from the environment
101 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
105 *) Allow certificate policies extension to use an IA5STRING for the
106 organization field. This is contrary to the PKIX definition but
107 VeriSign uses it and IE5 only recognises this form. Document 'x509'
111 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
112 without disallowing inline assembler and the like for non-pedantic builds.
115 *) Support Borland C++ builder.
116 [Janez Jere <jj@void.si>, modified by Ulf Möller]
121 *) SHA-1 cleanups and performance enhancements.
122 [Andy Polyakov <appro@fy.chalmers.se>]
124 *) Sparc v8plus assembler for the bignum library.
125 [Andy Polyakov <appro@fy.chalmers.se>]
127 *) Accept any -xxx and +xxx compiler options in Configure.
130 *) Update HPUX configuration.
133 *) Add missing sk_<type>_unshift() function to safestack.h
134 [Ralf S. Engelschall]
136 *) New function SSL_CTX_use_certificate_chain_file that sets the
137 "extra_cert"s in addition to the certificate. (This makes sense
138 only for "PEM" format files, as chains as a whole are not
142 *) Support verify_depth from the SSL API.
143 x509_vfy.c had what can be considered an off-by-one-error:
144 Its depth (which was not part of the external interface)
145 was actually counting the number of certificates in a chain;
146 now it really counts the depth.
149 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
150 instead of X509err, which often resulted in confusing error
151 messages since the error codes are not globally unique
152 (e.g. an alleged error in ssl3_accept when a certificate
153 didn't match the private key).
155 *) New function SSL_CTX_set_session_id_context that allows to set a default
156 value (so that you don't need SSL_set_session_id_context for each
157 connection using the SSL_CTX).
160 *) OAEP decoding bug fix.
163 *) Support INSTALL_PREFIX for package builders, as proposed by
167 *) New Configure options "threads" and "no-threads". For systems
168 where the proper compiler options are known (currently Solaris
169 and Linux), "threads" is the default.
172 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
175 *) Install various scripts to $(OPENSSLDIR)/misc, not to
176 $(INSTALLTOP)/bin -- they shouldn't clutter directories
177 such as /usr/local/bin.
180 *) "make linux-shared" to build shared libraries.
181 [Niels Poppe <niels@netbox.org>]
183 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
186 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
187 extension adding in x509 utility.
190 *) Remove NOPROTO sections and error code comments.
193 *) Partial rewrite of the DEF file generator to now parse the ANSI
197 *) New Configure options --prefix=DIR and --openssldir=DIR.
200 *) Complete rewrite of the error code script(s). It is all now handled
201 by one script at the top level which handles error code gathering,
202 header rewriting and C source file generation. It should be much better
203 than the old method: it now uses a modified version of Ulf's parser to
204 read the ANSI prototypes in all header files (thus the old K&R definitions
205 aren't needed for error creation any more) and do a better job of
206 translating function codes into names. The old 'ASN1 error code imbedded
207 in a comment' is no longer necessary and it doesn't use .err files which
208 have now been deleted. Also the error code call doesn't have to appear all
209 on one line (which resulted in some large lines...).
212 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
215 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
216 0 (which usually indicates a closed connection), but continue reading.
219 *) Fix some race conditions.
222 *) Add support for CRL distribution points extension. Add Certificate
223 Policies and CRL distribution points documentation.
226 *) Move the autogenerated header file parts to crypto/opensslconf.h.
229 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
230 8 of keying material. Merlin has also confirmed interop with this fix
231 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
232 [Merlin Hughes <merlin@baltimore.ie>]
234 *) Fix lots of warnings.
235 [Richard Levitte <levitte@stacken.kth.se>]
237 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
238 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
239 [Richard Levitte <levitte@stacken.kth.se>]
241 *) Fix problems with sizeof(long) == 8.
242 [Andy Polyakov <appro@fy.chalmers.se>]
244 *) Change functions to ANSI C.
247 *) Fix typos in error codes.
248 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
250 *) Remove defunct assembler files from Configure.
253 *) SPARC v8 assembler BIGNUM implementation.
254 [Andy Polyakov <appro@fy.chalmers.se>]
256 *) Support for Certificate Policies extension: both print and set.
257 Various additions to support the r2i method this uses.
260 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
261 return a const string when you are expecting an allocated buffer.
264 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
265 types DirectoryString and DisplayText.
268 *) Add code to allow r2i extensions to access the configuration database,
269 add an LHASH database driver and add several ctx helper functions.
272 *) Fix an evil bug in bn_expand2() which caused various BN functions to
273 fail when they extended the size of a BIGNUM.
276 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
277 support typesafe stack.
280 *) Fix typo in SSL_[gs]et_options().
281 [Nils Frostberg <nils@medcom.se>]
283 *) Delete various functions and files that belonged to the (now obsolete)
284 old X509V3 handling code.
287 *) New Configure option "rsaref".
290 *) Don't auto-generate pem.h.
293 *) Introduce type-safe ASN.1 SETs.
296 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
297 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
299 *) Introduce type-safe STACKs. This will almost certainly break lots of code
300 that links with OpenSSL (well at least cause lots of warnings), but fear
301 not: the conversion is trivial, and it eliminates loads of evil casts. A
302 few STACKed things have been converted already. Feel free to convert more.
303 In the fullness of time, I'll do away with the STACK type altogether.
306 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
307 specified in <certfile> by updating the entry in the index.txt file.
308 This way one no longer has to edit the index.txt file manually for
309 revoking a certificate. The -revoke option does the gory details now.
310 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
312 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
313 `-text' option at all and this way the `-noout -text' combination was
314 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
315 [Ralf S. Engelschall]
317 *) Make sure a corresponding plain text error message exists for the
318 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
319 verify callback function determined that a certificate was revoked.
320 [Ralf S. Engelschall]
322 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
323 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
324 all available cipers including rc5, which was forgotten until now.
325 In order to let the testing shell script know which algorithms
326 are available, a new (up to now undocumented) command
327 "openssl list-cipher-commands" is used.
330 *) Bugfix: s_client occasionally would sleep in select() when
331 it should have checked SSL_pending() first.
334 *) New functions DSA_do_sign and DSA_do_verify to provide access to
335 the raw DSA values prior to ASN.1 encoding.
338 *) Tweaks to Configure
339 Niels Poppe <niels@netbox.org>
341 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
345 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
348 *) New config option to avoid instructions that are illegal on the 80386.
349 The default code is faster, but requires at least a 486.
352 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
353 SSL2_SERVER_VERSION (not used at all) macros, which are now the
354 same as SSL2_VERSION anyway.
357 *) New "-showcerts" option for s_client.
360 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
361 application. Various cleanups and fixes.
364 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
365 modify error routines to work internally. Add error codes and PBE init
366 to library startup routines.
369 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
370 packing functions to asn1 and evp. Changed function names and error
374 *) PKCS12 integration: and so it begins... First of several patches to
375 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
379 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
380 and display support for Thawte strong extranet extension.
383 *) Add LinuxPPC support.
384 [Jeff Dubrule <igor@pobox.org>]
386 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
387 bn_div_words in alpha.s.
388 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
390 *) Make sure the RSA OAEP test is skipped under -DRSAref because
391 OAEP isn't supported when OpenSSL is built with RSAref.
392 [Ulf Moeller <ulf@fitug.de>]
394 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
395 so they no longer are missing under -DNOPROTO.
396 [Soren S. Jorvang <soren@t.dk>]
399 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
401 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
402 doesn't work when the session is reused. Coming soon!
405 *) Fix a security hole, that allows sessions to be reused in the wrong
406 context thus bypassing client cert protection! All software that uses
407 client certs and session caches in multiple contexts NEEDS PATCHING to
408 allow session reuse! A fuller solution is in the works.
409 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
411 *) Some more source tree cleanups (removed obsolete files
412 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
413 permission on "config" script to be executable) and a fix for the INSTALL
415 [Ulf Moeller <ulf@fitug.de>]
417 *) Remove some legacy and erroneous uses of malloc, free instead of
419 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
421 *) Make rsa_oaep_test return non-zero on error.
422 [Ulf Moeller <ulf@fitug.de>]
424 *) Add support for native Solaris shared libraries. Configure
425 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
426 if someone would make that last step automatic.
427 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
429 *) ctx_size was not built with the right compiler during "make links". Fixed.
432 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
433 except NULL ciphers". This means the default cipher list will no longer
434 enable NULL ciphers. They need to be specifically enabled e.g. with
435 the string "DEFAULT:eNULL".
438 *) Fix to RSA private encryption routines: if p < q then it would
439 occasionally produce an invalid result. This will only happen with
440 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
443 *) Be less restrictive and allow also `perl util/perlpath.pl
444 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
445 because this way one can also use an interpreter named `perl5' (which is
446 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
447 installed as `perl').
448 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
450 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
451 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
453 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
454 advapi32.lib to Win32 build and change the pem test comparision
455 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
456 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
457 and crypto/des/ede_cbcm_enc.c.
460 *) DES quad checksum was broken on big-endian architectures. Fixed.
463 *) Comment out two functions in bio.h that aren't implemented. Fix up the
464 Win32 test batch file so it (might) work again. The Win32 test batch file
465 is horrible: I feel ill....
468 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
469 in e_os.h. Audit of header files to check ANSI and non ANSI
470 sections: 10 functions were absent from non ANSI section and not exported
471 from Windows DLLs. Fixed up libeay.num for new functions.
474 *) Make `openssl version' output lines consistent.
475 [Ralf S. Engelschall]
477 *) Fix Win32 symbol export lists for BIO functions: Added
478 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
479 to ms/libeay{16,32}.def.
480 [Ralf S. Engelschall]
482 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
483 fine under Unix and passes some trivial tests I've now added. But the
484 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
485 added to make sure no one expects that this stuff really works in the
486 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
487 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
489 [Ralf S. Engelschall]
491 *) Fix the generation of two part addresses in perl.
492 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
494 *) Add config entry for Linux on MIPS.
495 [John Tobey <jtobey@channel1.com>]
497 *) Make links whenever Configure is run, unless we are on Windoze.
500 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
501 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
505 *) Add a useful kludge to allow package maintainers to specify compiler and
506 other platforms details on the command line without having to patch the
507 Configure script everytime: One now can use ``perl Configure
508 <id>:<details>'', i.e. platform ids are allowed to have details appended
509 to them (seperated by colons). This is treated as there would be a static
510 pre-configured entry in Configure's %table under key <id> with value
511 <details> and ``perl Configure <id>'' is called. So, when you want to
512 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
513 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
514 now, which overrides the FreeBSD-elf entry on-the-fly.
515 [Ralf S. Engelschall]
517 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
520 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
521 on the `perl Configure ...' command line. This way one can compile
522 OpenSSL libraries with Position Independent Code (PIC) which is needed
523 for linking it into DSOs.
524 [Ralf S. Engelschall]
526 *) Remarkably, export ciphers were totally broken and no-one had noticed!
530 *) Cleaned up the LICENSE document: The official contact for any license
531 questions now is the OpenSSL core team under openssl-core@openssl.org.
532 And add a paragraph about the dual-license situation to make sure people
533 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
534 to the OpenSSL toolkit.
535 [Ralf S. Engelschall]
537 *) General source tree makefile cleanups: Made `making xxx in yyy...'
538 display consistent in the source tree and replaced `/bin/rm' by `rm'.
539 Additonally cleaned up the `make links' target: Remove unnecessary
540 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
541 to speed processing and no longer clutter the display with confusing
542 stuff. Instead only the actually done links are displayed.
543 [Ralf S. Engelschall]
545 *) Permit null encryption ciphersuites, used for authentication only. It used
546 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
547 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
551 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
552 signed attributes when verifying signatures (this would break them),
553 the detached data encoding was wrong and public keys obtained using
554 X509_get_pubkey() weren't freed.
557 *) Add text documentation for the BUFFER functions. Also added a work around
558 to a Win95 console bug. This was triggered by the password read stuff: the
559 last character typed gets carried over to the next fread(). If you were
560 generating a new cert request using 'req' for example then the last
561 character of the passphrase would be CR which would then enter the first
565 *) Added the new `Includes OpenSSL Cryptography Software' button as
566 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
567 button and can be used by applications based on OpenSSL to show the
568 relationship to the OpenSSL project.
569 [Ralf S. Engelschall]
571 *) Remove confusing variables in function signatures in files
572 ssl/ssl_lib.c and ssl/ssl.h.
573 [Lennart Bong <lob@kulthea.stacken.kth.se>]
575 *) Don't install bss_file.c under PREFIX/include/
576 [Lennart Bong <lob@kulthea.stacken.kth.se>]
578 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
579 functions that return function pointers and has support for NT specific
580 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
581 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
582 unsigned to signed types: this was killing the Win32 compile.
585 *) Add new certificate file to stack functions,
586 SSL_add_dir_cert_subjects_to_stack() and
587 SSL_add_file_cert_subjects_to_stack(). These largely supplant
588 SSL_load_client_CA_file(), and can be used to add multiple certs easily
589 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
590 This means that Apache-SSL and similar packages don't have to mess around
591 to add as many CAs as they want to the preferred list.
594 *) Experiment with doxygen documentation. Currently only partially applied to
596 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
597 openssl.doxy as the configuration file.
600 *) Get rid of remaining C++-style comments which strict C compilers hate.
601 [Ralf S. Engelschall, pointed out by Carlos Amengual]
603 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
604 compiled in by default: it has problems with large keys.
607 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
608 DH private keys and/or callback functions which directly correspond to
609 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
610 is needed for applications which have to configure certificates on a
611 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
613 For the RSA certificate situation is makes no difference, but
614 for the DSA certificate situation this fixes the "no shared cipher"
615 problem where the OpenSSL cipher selection procedure failed because the
616 temporary keys were not overtaken from the context and the API provided
617 no way to reconfigure them.
618 The new functions now let applications reconfigure the stuff and they
619 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
620 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
621 non-public-API function ssl_cert_instantiate() is used as a helper
622 function and also to reduce code redundancy inside ssl_rsa.c.
623 [Ralf S. Engelschall]
625 *) Move s_server -dcert and -dkey options out of the undocumented feature
626 area because they are useful for the DSA situation and should be
627 recognized by the users.
628 [Ralf S. Engelschall]
630 *) Fix the cipher decision scheme for export ciphers: the export bits are
631 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
632 SSL_EXP_MASK. So, the original variable has to be used instead of the
633 already masked variable.
634 [Richard Levitte <levitte@stacken.kth.se>]
636 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
637 [Richard Levitte <levitte@stacken.kth.se>]
639 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
640 from `int' to `unsigned int' because it's a length and initialized by
641 EVP_DigestFinal() which expects an `unsigned int *'.
642 [Richard Levitte <levitte@stacken.kth.se>]
644 *) Don't hard-code path to Perl interpreter on shebang line of Configure
645 script. Instead use the usual Shell->Perl transition trick.
646 [Ralf S. Engelschall]
648 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
649 (in addition to RSA certificates) to match the behaviour of `openssl dsa
650 -noout -modulus' as it's already the case for `openssl rsa -noout
651 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
652 currently the public key is printed (a decision which was already done by
653 `openssl dsa -modulus' in the past) which serves a similar purpose.
654 Additionally the NO_RSA no longer completely removes the whole -modulus
655 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
657 [Ralf S. Engelschall]
659 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
660 BIO. See the source (crypto/evp/bio_ok.c) for more info.
661 [Arne Ansper <arne@ats.cyber.ee>]
663 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
664 to be added. Now both 'req' and 'ca' can use new objects defined in the
668 *) Add cool BIO that does syslog (or event log on NT).
669 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
671 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
672 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
673 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
674 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
677 *) Add preliminary config info for new extension code.
680 *) Make RSA_NO_PADDING really use no padding.
681 [Ulf Moeller <ulf@fitug.de>]
683 *) Generate errors when private/public key check is done.
686 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
687 for some CRL extensions and new objects added.
690 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
691 key usage extension and fuller support for authority key id.
694 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
695 padding method for RSA, which is recommended for new applications in PKCS
696 #1 v2.0 (RFC 2437, October 1998).
697 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
698 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
699 against Bleichbacher's attack on RSA.
700 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
703 *) Updates to the new SSL compression code
704 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
706 *) Fix so that the version number in the master secret, when passed
707 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
708 (because the server will not accept higher), that the version number
709 is 0x03,0x01, not 0x03,0x00
710 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
712 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
713 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
714 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
717 *) Support for RAW extensions where an arbitrary extension can be
718 created by including its DER encoding. See apps/openssl.cnf for
722 *) Make sure latest Perl versions don't interpret some generated C array
723 code as Perl array code in the crypto/err/err_genc.pl script.
724 [Lars Weber <3weber@informatik.uni-hamburg.de>]
726 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
727 not many people have the assembler. Various Win32 compilation fixes and
728 update to the INSTALL.W32 file with (hopefully) more accurate Win32
732 *) Modify configure script 'Configure' to automatically create crypto/date.h
733 file under Win32 and also build pem.h from pem.org. New script
734 util/mkfiles.pl to create the MINFO file on environments that can't do a
735 'make files': perl util/mkfiles.pl >MINFO should work.
738 *) Major rework of DES function declarations, in the pursuit of correctness
739 and purity. As a result, many evil casts evaporated, and some weirdness,
740 too. You may find this causes warnings in your code. Zapping your evil
741 casts will probably fix them. Mostly.
744 *) Fix for a typo in asn1.h. Bug fix to object creation script
745 obj_dat.pl. It considered a zero in an object definition to mean
746 "end of object": none of the objects in objects.h have any zeros
747 so it wasn't spotted.
748 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
750 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
751 Masking (CBCM). In the absence of test vectors, the best I have been able
752 to do is check that the decrypt undoes the encrypt, so far. Send me test
753 vectors if you have them.
756 *) Correct calculation of key length for export ciphers (too much space was
757 allocated for null ciphers). This has not been tested!
760 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
761 message is now correct (it understands "crypto" and "ssl" on its
762 command line). There is also now an "update" option. This will update
763 the util/ssleay.num and util/libeay.num files with any new functions.
765 perl util/mkdef.pl crypto ssl update
769 *) Overhauled the Perl interface (perl/*):
770 - ported BN stuff to OpenSSL's different BN library
771 - made the perl/ source tree CVS-aware
772 - renamed the package from SSLeay to OpenSSL (the files still contain
773 their history because I've copied them in the repository)
774 - removed obsolete files (the test scripts will be replaced
775 by better Test::Harness variants in the future)
776 [Ralf S. Engelschall]
778 *) First cut for a very conservative source tree cleanup:
779 1. merge various obsolete readme texts into doc/ssleay.txt
780 where we collect the old documents and readme texts.
781 2. remove the first part of files where I'm already sure that we no
782 longer need them because of three reasons: either they are just temporary
783 files which were left by Eric or they are preserved original files where
784 I've verified that the diff is also available in the CVS via "cvs diff
785 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
786 the crypto/md/ stuff).
787 [Ralf S. Engelschall]
789 *) More extension code. Incomplete support for subject and issuer alt
790 name, issuer and authority key id. Change the i2v function parameters
791 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
792 what that's for :-) Fix to ASN1 macro which messed up
793 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
796 *) Preliminary support for ENUMERATED type. This is largely copied from the
800 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
801 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
803 *) Make sure `make rehash' target really finds the `openssl' program.
804 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
806 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
807 like to hear about it if this slows down other processors.
810 *) Add CygWin32 platform information to Configure script.
811 [Alan Batie <batie@aahz.jf.intel.com>]
813 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
814 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
816 *) New program nseq to manipulate netscape certificate sequences
819 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
823 *) Fixes to BN code. Previously the default was to define BN_RECURSION
824 but the BN code had some problems that would cause failures when
825 doing certificate verification and some other functions.
826 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
828 *) Add ASN1 and PEM code to support netscape certificate sequences.
831 *) Add ASN1 and PEM code to support netscape certificate sequences.
834 *) Add several PKIX and private extended key usage OIDs.
837 *) Modify the 'ca' program to handle the new extension code. Modify
838 openssl.cnf for new extension format, add comments.
841 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
842 and add a sample to openssl.cnf so req -x509 now adds appropriate
846 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
847 error code, add initial support to X509_print() and x509 application.
850 *) Takes a deep breath and start addding X509 V3 extension support code. Add
851 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
852 stuff is currently isolated and isn't even compiled yet.
855 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
856 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
857 Removed the versions check from X509 routines when loading extensions:
858 this allows certain broken certificates that don't set the version
859 properly to be processed.
862 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
863 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
864 can still be regenerated with "make depend".
867 *) Spelling mistake in C version of CAST-128.
868 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
870 *) Changes to the error generation code. The perl script err-code.pl
871 now reads in the old error codes and retains the old numbers, only
872 adding new ones if necessary. It also only changes the .err files if new
873 codes are added. The makefiles have been modified to only insert errors
874 when needed (to avoid needlessly modifying header files). This is done
875 by only inserting errors if the .err file is newer than the auto generated
876 C file. To rebuild all the error codes from scratch (the old behaviour)
877 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
878 or delete all the .err files.
881 *) CAST-128 was incorrectly implemented for short keys. The C version has
882 been fixed, but is untested. The assembler versions are also fixed, but
883 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
884 to regenerate it if needed.
885 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
886 Hagino <itojun@kame.net>]
888 *) File was opened incorrectly in randfile.c.
889 [Ulf Möller <ulf@fitug.de>]
891 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
892 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
893 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
894 al: it's just almost always a UTCTime. Note this patch adds new error
895 codes so do a "make errors" if there are problems.
898 *) Correct Linux 1 recognition in config.
899 [Ulf Möller <ulf@fitug.de>]
901 *) Remove pointless MD5 hash when using DSA keys in ca.
902 [Anonymous <nobody@replay.com>]
904 *) Generate an error if given an empty string as a cert directory. Also
905 generate an error if handed NULL (previously returned 0 to indicate an
906 error, but didn't set one).
907 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
909 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
912 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
913 parameters. This was causing a warning which killed off the Win32 compile.
916 *) Remove C++ style comments from crypto/bn/bn_local.h.
917 [Neil Costigan <neil.costigan@celocom.com>]
919 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
920 based on a text string, looking up short and long names and finally
921 "dot" format. The "dot" format stuff didn't work. Added new function
922 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
923 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
924 OID is not part of the table.
927 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
928 X509_LOOKUP_by_alias().
931 *) Sort openssl functions by name.
934 *) Get the gendsa program working (hopefully) and add it to app list. Remove
935 encryption from sample DSA keys (in case anyone is interested the password
939 *) Make _all_ *_free functions accept a NULL pointer.
940 [Frans Heymans <fheymans@isaserver.be>]
942 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
944 [Anonymous <nobody@replay.com>]
946 *) s_server should send the CAfile as acceptable CAs, not its own cert.
947 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
949 *) Don't blow it for numeric -newkey arguments to apps/req.
950 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
952 *) Temp key "for export" tests were wrong in s3_srvr.c.
953 [Anonymous <nobody@replay.com>]
955 *) Add prototype for temp key callback functions
956 SSL_CTX_set_tmp_{rsa,dh}_callback().
959 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
960 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
963 *) X509_name_add_entry() freed the wrong thing after an error.
964 [Arne Ansper <arne@ats.cyber.ee>]
966 *) rsa_eay.c would attempt to free a NULL context.
967 [Arne Ansper <arne@ats.cyber.ee>]
969 *) BIO_s_socket() had a broken should_retry() on Windoze.
970 [Arne Ansper <arne@ats.cyber.ee>]
972 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
973 [Arne Ansper <arne@ats.cyber.ee>]
975 *) Make sure the already existing X509_STORE->depth variable is initialized
976 in X509_STORE_new(), but document the fact that this variable is still
977 unused in the certificate verification process.
978 [Ralf S. Engelschall]
980 *) Fix the various library and apps files to free up pkeys obtained from
981 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
984 *) Fix reference counting in X509_PUBKEY_get(). This makes
985 demos/maurice/example2.c work, amongst others, probably.
986 [Steve Henson and Ben Laurie]
988 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
989 `openssl' and second, the shortcut symlinks for the `openssl <command>'
990 are no longer created. This way we have a single and consistent command
991 line interface `openssl <command>', similar to `cvs <command>'.
992 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
994 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
995 BIT STRING wrapper always have zero unused bits.
998 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1001 *) Make the top-level INSTALL documentation easier to understand.
1004 *) Makefiles updated to exit if an error occurs in a sub-directory
1005 make (including if user presses ^C) [Paul Sutton]
1007 *) Make Montgomery context stuff explicit in RSA data structure.
1010 *) Fix build order of pem and err to allow for generated pem.h.
1013 *) Fix renumbering bug in X509_NAME_delete_entry().
1016 *) Enhanced the err-ins.pl script so it makes the error library number
1017 global and can add a library name. This is needed for external ASN1 and
1018 other error libraries.
1021 *) Fixed sk_insert which never worked properly.
1024 *) Fix ASN1 macros so they can handle indefinite length construted
1025 EXPLICIT tags. Some non standard certificates use these: they can now
1029 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1030 into a single doc/ssleay.txt bundle. This way the information is still
1031 preserved but no longer messes up this directory. Now it's new room for
1032 the new set of documenation files.
1033 [Ralf S. Engelschall]
1035 *) SETs were incorrectly DER encoded. This was a major pain, because they
1036 shared code with SEQUENCEs, which aren't coded the same. This means that
1037 almost everything to do with SETs or SEQUENCEs has either changed name or
1038 number of arguments.
1039 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1041 *) Fix test data to work with the above.
1044 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1045 was already fixed by Eric for 0.9.1 it seems.
1046 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1048 *) Autodetect FreeBSD3.
1051 *) Fix various bugs in Configure. This affects the following platforms:
1055 unixware-2.0-pentium
1059 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1060 before they are needed.
1063 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1067 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1069 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1070 changed SSLeay to OpenSSL in version strings.
1071 [Ralf S. Engelschall]
1073 *) Some fixups to the top-level documents.
1076 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1077 because the symlink to include/ was missing.
1078 [Ralf S. Engelschall]
1080 *) Incorporated the popular no-RSA/DSA-only patches
1081 which allow to compile a RSA-free SSLeay.
1082 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1084 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1085 when "ssleay" is still not found.
1086 [Ralf S. Engelschall]
1088 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1089 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1091 *) Updated the README file.
1092 [Ralf S. Engelschall]
1094 *) Added various .cvsignore files in the CVS repository subdirs
1095 to make a "cvs update" really silent.
1096 [Ralf S. Engelschall]
1098 *) Recompiled the error-definition header files and added
1099 missing symbols to the Win32 linker tables.
1100 [Ralf S. Engelschall]
1102 *) Cleaned up the top-level documents;
1103 o new files: CHANGES and LICENSE
1104 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1105 o merged COPYRIGHT into LICENSE
1106 o removed obsolete TODO file
1107 o renamed MICROSOFT to INSTALL.W32
1108 [Ralf S. Engelschall]
1110 *) Removed dummy files from the 0.9.1b source tree:
1111 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1112 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1115 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1116 [Ralf S. Engelschall]
1118 *) Added various platform portability fixes.
1121 *) The Genesis of the OpenSSL rpject:
1122 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1123 Young and Tim J. Hudson created while they were working for C2Net until
1125 [The OpenSSL Project]
1128 Changes between 0.9.0b and 0.9.1b [not released]
1130 *) Updated a few CA certificates under certs/
1133 *) Changed some BIGNUM api stuff.
1136 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1137 DGUX x86, Linux Alpha, etc.
1140 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1141 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1145 *) Add -strparse option to asn1pars program which parses nested
1147 [Dr Stephen Henson <shenson@bigfoot.com>]
1149 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1152 *) DSA fix for "ca" program.
1155 *) Added "-genkey" option to "dsaparam" program.
1158 *) Added RIPE MD160 (rmd160) message digest.
1161 *) Added -a (all) option to "ssleay version" command.
1164 *) Added PLATFORM define which is the id given to Configure.
1167 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1170 *) Extended the ASN.1 parser routines.
1173 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1176 *) Added a BN_CTX to the BN library.
1179 *) Fixed the weak key values in DES library
1182 *) Changed API in EVP library for cipher aliases.
1185 *) Added support for RC2/64bit cipher.
1188 *) Converted the lhash library to the crypto/mem.c functions.
1191 *) Added more recognized ASN.1 object ids.
1194 *) Added more RSA padding checks for SSL/TLS.
1197 *) Added BIO proxy/filter functionality.
1200 *) Added extra_certs to SSL_CTX which can be used
1201 send extra CA certificates to the client in the CA cert chain sending
1202 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1205 *) Now Fortezza is denied in the authentication phase because
1206 this is key exchange mechanism is not supported by SSLeay at all.
1209 *) Additional PKCS1 checks.
1212 *) Support the string "TLSv1" for all TLS v1 ciphers.
1215 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1216 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1219 *) Fixed a few memory leaks.
1222 *) Fixed various code and comment typos.
1225 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1226 bytes sent in the client random.
1227 [Edward Bishop <ebishop@spyglass.com>]
