B
 
Bodo Möller 已提交
9 10
     [Bodo Moeller]

11 12 13 14
  *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
     0 (which usually indicates a closed connection), but continue reading.
     [Bodo Moeller]

Bodo Möller 已提交
15 16 17
  *) Fix some race conditions.
     [Bodo Moeller]

  *) Add support for CRL distribution points extension. Add Certificate
     Policies and CRL distribution points documentation.
     [Steve Henson]

22 23 24
  *) Move the autogenerated header file parts to crypto/opensslconf.h.
     [Ulf Möller]

B
Ben Laurie 已提交
25 26 27 28 29
  *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
     8 of keying material. Merlin has also confirmed interop with this fix
     between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
     [Merlin Hughes <merlin@baltimore.ie>]

Ulf Möller 已提交
30 31 32 33 34
  *) Fix lots of warnings.
     [Richard Levitte <levitte@stacken.kth.se>]
 
  *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
     the directory spec didn't end with a LIST_SEPARATOR_CHAR.

52
  *) Support for Certificate Policies extension: both print and set.
53
     Various additions to support the r2i method this uses.
54 55
     [Steve Henson]

B
Ben Laurie 已提交
56 57 58 59
  *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
     return a const string when you are expecting an allocated buffer.
     [Ben Laurie]

60 61
  *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
     types DirectoryString and DisplayText.
62 63
     [Steve Henson]

64 65 66 67
  *) Add code to allow r2i extensions to access the configuration database,
     add an LHASH database driver and add several ctx helper functions.
     [Steve Henson]

68 69 70 71
  *) Fix an evil bug in bn_expand2() which caused various BN functions to
     fail when they extended the size of a BIGNUM.
     [Steve Henson]

72 73 74 75
  *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
     support typesafe stack.
     [Steve Henson]

B
Typo.  
Ben Laurie 已提交
76 77 78
  *) Fix typo in SSL_[gs]et_options().
     [Nils Frostberg <nils@medcom.se>]

79 80 81 82
  *) Delete various functions and files that belonged to the (now obsolete)
     old X509V3 handling code.
     [Steve Henson]

U
Ulf Möller 已提交
83 84 85
  *) New Configure option "rsaref".
     [Ulf Möller]

86 87 88
  *) Don't auto-generate pem.h.
     [Bodo Moeller]

B
Ben Laurie 已提交
89 90 91 92 93 94 95 96 97 98
  *) Introduce type-safe ASN.1 SETs.
     [Ben Laurie]

  *) Introduce type-safe STACKs. This will almost certainly break lots of code
     that links with OpenSSL (well at least cause lots of warnings), but fear
     not: the conversion is trivial, and it eliminates loads of evil casts. A
     few STACKed things have been converted already. Feel free to convert more.
     In the fullness of time, I'll do away with the STACK type altogether.
     [Ben Laurie]

99 100 101 102 103 104
  *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
     specified in <certfile> by updating the entry in the index.txt file.
     This way one no longer has to edit the index.txt file manually for
     revoking a certificate. The -revoke option does the gory details now.
     [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]

105 106 107 108 109
  *) Fix `openssl crl -noout -text' combination where `-noout' killed the
     `-text' option at all and this way the `-noout -text' combination was
     inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
     [Ralf S. Engelschall]

110 111 112 113 114
  *) Make sure a corresponding plain text error message exists for the
     X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
     verify callback function determined that a certificate was revoked.
     [Ralf S. Engelschall]

B
 
Bodo Möller 已提交
115 116 117 118 119 120 121 122
  *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
     ciphers that were excluded, e.g. by -DNO_IDEA.  Also, test
     all available cipers including rc5, which was forgotten until now.
     In order to let the testing shell script know which algorithms
     are available, a new (up to now undocumented) command
     "openssl list-cipher-commands" is used.
     [Bodo Moeller]

123 124 125 126
  *) Bugfix: s_client occasionally would sleep in select() when
     it should have checked SSL_pending() first.
     [Bodo Moeller]

U
Ulf Möller 已提交
127 128 129 130 131 132 133
  *) New functions DSA_do_sign and DSA_do_verify to provide access to
     the raw DSA values prior to ASN.1 encoding.
     [Ulf Möller]

  *) Tweaks to Configure
     Niels Poppe <niels@netbox.org>

134 135 136 137
  *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
     yet...
     [Steve Henson]

138 139 140
  *) New variables $(RANLIB) and $(PERL) in the Makefiles.
     [Ulf Möller]

U
Ulf Möller 已提交
141 142 143 144
  *) New config option to avoid instructions that are illegal on the 80386.
     The default code is faster, but requires at least a 486.
     [Ulf Möller]
  
145 146 147 148 149 150 151 152
  *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
     SSL2_SERVER_VERSION (not used at all) macros, which are now the
     same as SSL2_VERSION anyway.
     [Bodo Moeller]

  *) New "-showcerts" option for s_client.
     [Bodo Moeller]

153 154 155 156
  *) Still more PKCS#12 integration. Add pkcs12 application to openssl
     application. Various cleanups and fixes.
     [Steve Henson]

157 158 159 160 161
  *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
     modify error routines to work internally. Add error codes and PBE init
     to library startup routines.
     [Steve Henson]

162 163 164 165 166
  *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
     packing functions to asn1 and evp. Changed function names and error
     codes along the way.
     [Steve Henson]

167 168
  *) PKCS12 integration: and so it begins... First of several patches to
     slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
169
     objects to objects.h
170 171
     [Steve Henson]

172 173 174 175
  *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
     and display support for Thawte strong extranet extension.
     [Steve Henson]

B
Ben Laurie 已提交
176 177 178
  *) Add LinuxPPC support.
     [Jeff Dubrule <igor@pobox.org>]

179 180 181 182
  *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
     bn_div_words in alpha.s.
     [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]

183 184 185 186
  *) Make sure the RSA OAEP test is skipped under -DRSAref because
     OAEP isn't supported when OpenSSL is built with RSAref.
     [Ulf Moeller <ulf@fitug.de>]

187 188 189 190
  *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h 
     so they no longer are missing under -DNOPROTO. 
     [Soren S. Jorvang <soren@t.dk>]

R
Ralf S. Engelschall 已提交
191
 Changes between 0.9.1c and 0.9.2b
192

B
Ben Laurie 已提交
193 194 195 196 197 198 199 200 201 202
  *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
     doesn't work when the session is reused. Coming soon!
     [Ben Laurie]

  *) Fix a security hole, that allows sessions to be reused in the wrong
     context thus bypassing client cert protection! All software that uses
     client certs and session caches in multiple contexts NEEDS PATCHING to
     allow session reuse! A fuller solution is in the works.
     [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]

203 204 205 206 207 208
  *) Some more source tree cleanups (removed obsolete files
     crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
     permission on "config" script to be executable) and a fix for the INSTALL
     document.
     [Ulf Moeller <ulf@fitug.de>]

209 210 211 212
  *) Remove some legacy and erroneous uses of malloc, free instead of
     Malloc, Free.
     [Lennart Bang <lob@netstream.se>, with minor changes by Steve]

B
Ben Laurie 已提交
213 214 215
  *) Make rsa_oaep_test return non-zero on error.
     [Ulf Moeller <ulf@fitug.de>]

B
Ben Laurie 已提交
216 217 218 219 220
  *) Add support for native Solaris shared libraries. Configure
     solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
     if someone would make that last step automatic.
     [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]

221 222 223
  *) ctx_size was not built with the right compiler during "make links". Fixed.
     [Ben Laurie]

224 225 226 227 228 229
  *) Change the meaning of 'ALL' in the cipher list. It now means "everything
     except NULL ciphers". This means the default cipher list will no longer
     enable NULL ciphers. They need to be specifically enabled e.g. with
     the string "DEFAULT:eNULL".
     [Steve Henson]

230 231 232 233 234
  *) Fix to RSA private encryption routines: if p < q then it would
     occasionally produce an invalid result. This will only happen with
     externally generated keys because OpenSSL (and SSLeay) ensure p > q.
     [Steve Henson]

235 236 237 238 239 240 241
  *) Be less restrictive and allow also `perl util/perlpath.pl
     /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
     because this way one can also use an interpreter named `perl5' (which is
     usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
     installed as `perl').
     [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]

242 243 244
  *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
     [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]

245 246 247
  *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
     advapi32.lib to Win32 build and change the pem test comparision
     to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
248 249 250
     suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
     and crypto/des/ede_cbcm_enc.c.
     [Steve Henson]
251

B
Ben Laurie 已提交
252 253 254
  *) DES quad checksum was broken on big-endian architectures. Fixed.
     [Ben Laurie]

255 256 257 258 259
  *) Comment out two functions in bio.h that aren't implemented. Fix up the
     Win32 test batch file so it (might) work again. The Win32 test batch file
     is horrible: I feel ill....
     [Steve Henson]

260 261 262 263
  *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
     in e_os.h. Audit of header files to check ANSI and non ANSI
     sections: 10 functions were absent from non ANSI section and not exported
     from Windows DLLs. Fixed up libeay.num for new functions.
264
     [Steve Henson]
265

266 267 268
  *) Make `openssl version' output lines consistent.
     [Ralf S. Engelschall]

269 270 271 272 273
  *) Fix Win32 symbol export lists for BIO functions: Added
     BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
     to ms/libeay{16,32}.def.
     [Ralf S. Engelschall]

274 275 276 277 278 279 280 281 282
  *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
     fine under Unix and passes some trivial tests I've now added. But the
     whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
     added to make sure no one expects that this stuff really works in the
     OpenSSL 0.9.2 release.  Additionally I've started to clean the XS sources
     up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
     openssl_bio.xs.
     [Ralf S. Engelschall]

B
Ben Laurie 已提交
283 284 285
  *) Fix the generation of two part addresses in perl.
     [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]

B
Ben Laurie 已提交
286 287 288
  *) Add config entry for Linux on MIPS.
     [John Tobey <jtobey@channel1.com>]

B
Ben Laurie 已提交
289
  *) Make links whenever Configure is run, unless we are on Windoze.
B
Ben Laurie 已提交
290 291
     [Ben Laurie]

292 293 294
  *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
     Currently only issuerAltName and AuthorityKeyIdentifier make any sense
     in CRLs.
295
     [Steve Henson]
296

297 298 299 300 301 302 303 304 305 306 307 308
  *) Add a useful kludge to allow package maintainers to specify compiler and
     other platforms details on the command line without having to patch the
     Configure script everytime: One now can use ``perl Configure
     <id>:<details>'', i.e. platform ids are allowed to have details appended
     to them (seperated by colons). This is treated as there would be a static
     pre-configured entry in Configure's %table under key <id> with value
     <details> and ``perl Configure <id>'' is called.  So, when you want to
     perform a quick test-compile under FreeBSD 3.1 with pgcc and without
     assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
     now, which overrides the FreeBSD-elf entry on-the-fly.
     [Ralf S. Engelschall]

B
Ben Laurie 已提交
309 310 311
  *) Disable new TLS1 ciphersuites by default: they aren't official yet.
     [Ben Laurie]

312 313 314 315 316 317
  *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
     on the `perl Configure ...' command line. This way one can compile
     OpenSSL libraries with Position Independent Code (PIC) which is needed
     for linking it into DSOs.
     [Ralf S. Engelschall]

B
Ben Laurie 已提交
318 319 320 321
  *) Remarkably, export ciphers were totally broken and no-one had noticed!
     Fixed.
     [Ben Laurie]

322 323 324 325 326 327 328
  *) Cleaned up the LICENSE document: The official contact for any license
     questions now is the OpenSSL core team under openssl-core@openssl.org.
     And add a paragraph about the dual-license situation to make sure people
     recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
     to the OpenSSL toolkit.
     [Ralf S. Engelschall]

329 330 331 332 333 334 335 336
  *) General source tree makefile cleanups: Made `making xxx in yyy...'
     display consistent in the source tree and replaced `/bin/rm' by `rm'.
     Additonally cleaned up the `make links' target: Remove unnecessary
     semicolons, subsequent redundant removes, inline point.sh into mklink.sh
     to speed processing and no longer clutter the display with confusing
     stuff. Instead only the actually done links are displayed.
     [Ralf S. Engelschall]

B
Ben Laurie 已提交
337 338 339 340 341 342
  *) Permit null encryption ciphersuites, used for authentication only. It used
     to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
     It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
     encryption.
     [Ben Laurie]

343 344 345 346 347 348
  *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
     signed attributes when verifying signatures (this would break them), 
     the detached data encoding was wrong and public keys obtained using
     X509_get_pubkey() weren't freed.
     [Steve Henson]

349 350 351 352 353 354
  *) Add text documentation for the BUFFER functions. Also added a work around
     to a Win95 console bug. This was triggered by the password read stuff: the
     last character typed gets carried over to the next fread(). If you were 
     generating a new cert request using 'req' for example then the last
     character of the passphrase would be CR which would then enter the first
     field as blank.
355 356
     [Steve Henson]

357 358 359 360 361 362
  *) Added the new `Includes OpenSSL Cryptography Software' button as
     doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
     button and can be used by applications based on OpenSSL to show the
     relationship to the OpenSSL project.  
     [Ralf S. Engelschall]

363 364 365 366
  *) Remove confusing variables in function signatures in files
     ssl/ssl_lib.c and ssl/ssl.h.
     [Lennart Bong <lob@kulthea.stacken.kth.se>]

367 368 369
  *) Don't install bss_file.c under PREFIX/include/
     [Lennart Bong <lob@kulthea.stacken.kth.se>]

370 371 372 373 374 375 376
  *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
     functions that return function pointers and has support for NT specific
     stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
     #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
     unsigned to signed types: this was killing the Win32 compile.
     [Steve Henson]

377 378 379 380 381
  *) Add new certificate file to stack functions,
     SSL_add_dir_cert_subjects_to_stack() and
     SSL_add_file_cert_subjects_to_stack().  These largely supplant
     SSL_load_client_CA_file(), and can be used to add multiple certs easily
     to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
382 383 384 385
     This means that Apache-SSL and similar packages don't have to mess around
     to add as many CAs as they want to the preferred list.
     [Ben Laurie]

386 387 388 389 390
  *) Experiment with doxygen documentation. Currently only partially applied to
     ssl/ssl_lib.c.
     See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
     openssl.doxy as the configuration file.
     [Ben Laurie]
391 392 393
  
  *) Get rid of remaining C++-style comments which strict C compilers hate.
     [Ralf S. Engelschall, pointed out by Carlos Amengual]
394

395 396 397 398
  *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
     compiled in by default: it has problems with large keys.
     [Steve Henson]

399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416
  *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
     DH private keys and/or callback functions which directly correspond to
     their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
     is needed for applications which have to configure certificates on a
     per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
     (e.g. s_server). 
        For the RSA certificate situation is makes no difference, but
     for the DSA certificate situation this fixes the "no shared cipher"
     problem where the OpenSSL cipher selection procedure failed because the
     temporary keys were not overtaken from the context and the API provided
     no way to reconfigure them. 
        The new functions now let applications reconfigure the stuff and they
     are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
     SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback.  Additionally a new
     non-public-API function ssl_cert_instantiate() is used as a helper
     function and also to reduce code redundancy inside ssl_rsa.c.
     [Ralf S. Engelschall]

417 418 419 420 421
  *) Move s_server -dcert and -dkey options out of the undocumented feature
     area because they are useful for the DSA situation and should be
     recognized by the users.
     [Ralf S. Engelschall]

422 423 424 425 426 427
  *) Fix the cipher decision scheme for export ciphers: the export bits are
     *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within

440 441 442 443 444 445 446 447 448 449 450
  *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
     (in addition to RSA certificates) to match the behaviour of `openssl dsa
     -noout -modulus' as it's already the case for `openssl rsa -noout
     -modulus'.  For RSA the -modulus is the real "modulus" while for DSA
     currently the public key is printed (a decision which was already done by
     `openssl dsa -modulus' in the past) which serves a similar purpose.
     Additionally the NO_RSA no longer completely removes the whole -modulus
     option; it now only avoids using the RSA stuff. Same applies to NO_DSA
     now, too.

     padding method for RSA, which is recommended for new applications in PKCS
     #1 v2.0 (RFC 2437, October 1998).
     OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
     foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure

530 531 532 533 534 535
  *) Major rework of DES function declarations, in the pursuit of correctness

     too. You may find this causes warnings in your code. Zapping your evil
     casts will probably fix them. Mostly.

536 537 538 539 540 541
  *) Fix for a typo in asn1.h. Bug fix to object creation script
     obj_dat.pl. It considered a zero in an object definition to mean

     - ported BN stuff to OpenSSL's different BN library
     - made the perl/ source tree CVS-aware
     - renamed the package from SSLeay to OpenSSL (the files still contain
       their history because I've copied them in the repository)

  *) First cut for a very conservative source tree cleanup:
     1. merge various obsolete readme texts into doc/ssleay.txt
     where we collect the old documents and readme texts.
     2. remove the first part of files where I'm already sure that we no
     longer need them because of three reasons: either they are just temporary
     files which were left by Eric or they are preserved original files where
     I've verified that the diff is also available in the CVS via "cvs diff
     -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
     the crypto/md/ stuff).

581 582 583 584 585 586 587
  *) More extension code. Incomplete support for subject and issuer alt
     name, issuer and authority key id. Change the i2v function parameters
     and add an extra 'crl' parameter in the X509V3_CTX structure: guess
     what that's for :-) Fix to ASN1 macro which messed up
     IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.

588 589 590 591
  *) Preliminary support for ENUMERATED type. This is largely copied from the

     CA extensions.
     [Steve Henson]

     [Steve Henson]
641

642 643 644 645 646
  *) Takes a deep breath and start addding X509 V3 extension support code. Add

     ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
     Removed the versions check from X509 routines when loading extensions:
     this allows certain broken certificates that don't set the version
     properly to be processed.
     [Steve Henson]

654 655 656 657 658

662 663 664 665 666 667 668 669 670
  *) Changes to the error generation code. The perl script err-code.pl 
     now reads in the old error codes and retains the old numbers, only
     adding new ones if necessary. It also only changes the .err files if new
     codes are added. The makefiles have been modified to only insert errors
     when needed (to avoid needlessly modifying header files). This is done
     by only inserting errors if the .err file is newer than the auto generated
     C file. To rebuild all the error codes from scratch (the old behaviour)
     either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
     or delete all the .err files.

     based on a text string, looking up short and long names and finally
     "dot" format. The "dot" format stuff didn't work. Added new function
     OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
