   6  Changes between 0.9.1c and 0.9.2
   7
   8   *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
   9      [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
  10
  11   *) New program nseq to manipulate netscape certificate sequences
  12      [Steve Henson]
  13
  14   *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
  15      few typos.
  16      [Steve Henson]
  17
  18   *) Fixes to BN code.  Previously the default was to define BN_RECURSION
  19      but the BN code had some problems that would cause failures when
  20      doing certificate verification and some other functions.
  21      [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
  22
  23   *) Add ASN1 and PEM code to support netscape certificate sequences.
  24      [Steve Henson]
  25
  26   *) Add ASN1 and PEM code to support netscape certificate sequences.
  27      [Steve Henson]
  28
  29   *) Add several PKIX and private extended key usage OIDs.
  30      [Steve Henson]
  31
  32   *) Modify the 'ca' program to handle the new extension code. Modify
  33      openssl.cnf for new extension format, add comments.
  34      [Steve Henson]
  35
  36   *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
  37      and add a sample to openssl.cnf so req -x509 now adds appropriate
  38      CA extensions.
  39      [Steve Henson]
  40
  41   *) Continued X509 V3 changes. Add to other makefiles, integrate with the
  42      error code, add initial support to X509_print() and x509 application.
  43      [Steve Henson]
  44
  45   *) Takes a deep breath and start addding X509 V3 extension support code. Add
  46      files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
  47      stuff is currently isolated and isn't even compiled yet.
  48      [Steve Henson]
  49
  50   *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
  51      ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
  52      Removed the versions check from X509 routines when loading extensions:
  53      this allows certain broken certificates that don't set the version
  54      properly to be processed.
  55      [Steve Henson]
  56
  57   *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
  58      Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
  59      can still be regenerated with "make depend".
  60      [Ben Laurie]
  61
  62   *) Spelling mistake in C version of CAST-128.
  63      [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
  64
  65   *) Changes to the error generation code. The perl script err-code.pl
  66      now reads in the old error codes and retains the old numbers, only
  67      adding new ones if necessary. It also only changes the .err files if new
  68      codes are added. The makefiles have been modified to only insert errors
  69      when needed (to avoid needlessly modifying header files). This is done
  70      by only inserting errors if the .err file is newer than the auto generated
  71      C file. To rebuild all the error codes from scratch (the old behaviour)
  72      either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
  73      or delete all the .err files.
  74      [Steve Henson]
  75
  76   *) CAST-128 was incorrectly implemented for short keys. The C version has
  77      been fixed, but is untested. The assembler versions are also fixed, but
  78      new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
  79      to regenerate it if needed.
  80      [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
  81       Hagino <itojun@kame.net>]
  82
  83   *) File was opened incorrectly in randfile.c.
  84      [Ulf Möller <ulf@fitug.de>]
  85
  86   *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
  87      functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
  88      GeneralizedTime. ASN1_TIME is the proper type used in certificates et
  89      al: it's just almost always a UTCTime. Note this patch adds new error
  90      codes so do a "make errors" if there are problems.
  91      [Steve Henson]
  92
  93   *) Correct Linux 1 recognition in config.
  94      [Ulf Möller <ulf@fitug.de>]
  95
  96   *) Remove pointless MD5 hash when using DSA keys in ca.
  97      [Anonymous <nobody@replay.com>]
  98
  99   *) Generate an error if given an empty string as a cert directory. Also
 100      generate an error if handed NULL (previously returned 0 to indicate an
 101      error, but didn't set one).
 102      [Ben Laurie, reported by Anonymous <nobody@replay.com>]
 103
 104   *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
 105      [Ben Laurie]
 106
 107   *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
 108      parameters. This was causing a warning which killed off the Win32 compile.
 109      [Steve Henson]
 110
 111   *) Remove C++ style comments from crypto/bn/bn_local.h.
 112      [Neil Costigan <neil.costigan@celocom.com>]
 113
 114   *) The function OBJ_txt2nid was broken. It was supposed to return a nid
 115      based on a text string, looking up short and long names and finally
 116      "dot" format. The "dot" format stuff didn't work. Added new function
 117      OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
 118      OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
 119      OID is not part of the table.
 120      [Steve Henson]
 121
 122   *) Add prototypes to X509 lookup/verify methods, fixing a bug in
 123      X509_LOOKUP_by_alias().
 124      [Ben Laurie]
 125
 126   *) Sort openssl functions by name.
 127      [Ben Laurie]
 128
 129   *) Get the gendsa program working (hopefully) and add it to app list. Remove
 130      encryption from sample DSA keys (in case anyone is interested the password
 131      was "1234").
 132      [Steve Henson]
 133
 134   *) Make _all_ *_free functions accept a NULL pointer.
 135      [Frans Heymans <fheymans@isaserver.be>]
 136
 137   *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
 138      NULL pointers.
 139      [Anonymous <nobody@replay.com>]
 140
 141   *) s_server should send the CAfile as acceptable CAs, not its own cert.
 142      [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
 143
 144   *) Don't blow it for numeric -newkey arguments to apps/req.
 145      [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
 146
 147   *) Temp key "for export" tests were wrong in s3_srvr.c.
 148      [Anonymous <nobody@replay.com>]
 149
 150   *) Add prototype for temp key callback functions
 151      SSL_CTX_set_tmp_{rsa,dh}_callback().
 152      [Ben Laurie]
 153
 154   *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
 155      DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
 156      [Steve Henson]
 157
 158   *) X509_name_add_entry() freed the wrong thing after an error.
 159      [Arne Ansper <arne@ats.cyber.ee>]
 160
 161   *) rsa_eay.c would attempt to free a NULL context.
 162      [Arne Ansper <arne@ats.cyber.ee>]
 163
 164   *) BIO_s_socket() had a broken should_retry() on Windoze.
 165      [Arne Ansper <arne@ats.cyber.ee>]
 166
 167   *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
 168      [Arne Ansper <arne@ats.cyber.ee>]
 169
 170   *) Make sure the already existing X509_STORE->depth variable is initialized
 171      in X509_STORE_new(), but document the fact that this variable is still
 172      unused in the certificate verification process.
 173      [Ralf S. Engelschall]
 174
 175   *) Fix the various library and apps files to free up pkeys obtained from
 176      X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
 177      [Steve Henson]
 178
 179   *) Fix reference counting in X509_PUBKEY_get(). This makes
 180      demos/maurice/example2.c work, amongst others, probably.
 181      [Steve Henson and Ben Laurie]
 182
 183   *) First cut of a cleanup for apps/. First the `ssleay' program is now named
 184      `openssl' and second, the shortcut symlinks for the `openssl <command>'
 185      are no longer created. This way we have a single and consistent command
 186      line interface `openssl <command>', similar to `cvs <command>'.
 187      [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
 188
 189   *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
 190      BIT STRING wrapper always have zero unused bits.
 191      [Steve Henson]
 192
 193   *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
 194      [Steve Henson]
 195
 196   *) Make the top-level INSTALL documentation easier to understand.
 197      [Paul Sutton]
 198
 199   *) Makefiles updated to exit if an error occurs in a sub-directory
 200      make (including if user presses ^C) [Paul Sutton]
 201
 202   *) Make Montgomery context stuff explicit in RSA data structure.
 203      [Ben Laurie]
 204
 205   *) Fix build order of pem and err to allow for generated pem.h.
 206      [Ben Laurie]
 207
 208   *) Fix renumbering bug in X509_NAME_delete_entry().
 209      [Ben Laurie]
 210
 211   *) Enhanced the err-ins.pl script so it makes the error library number
 212      global and can add a library name. This is needed for external ASN1 and
 213      other error libraries.
 214      [Steve Henson]
 215
 216   *) Fixed sk_insert which never worked properly.
 217      [Steve Henson]
 218
 219   *) Fix ASN1 macros so they can handle indefinite length construted
 220      EXPLICIT tags. Some non standard certificates use these: they can now
 221      be read in.
 222      [Steve Henson]
 223
 224   *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
 225      into a single doc/ssleay.txt bundle. This way the information is still
 226      preserved but no longer messes up this directory. Now it's new room for
 227      the new set of documenation files.
 228      [Ralf S. Engelschall]
 229
 230   *) SETs were incorrectly DER encoded. This was a major pain, because they
 231      shared code with SEQUENCEs, which aren't coded the same. This means that
 232      almost everything to do with SETs or SEQUENCEs has either changed name or
 233      number of arguments.
 234      [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
 235
 236   *) Fix test data to work with the above.
 237      [Ben Laurie]
 238
 239   *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
 240      was already fixed by Eric for 0.9.1 it seems.
 241      [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
 242
 243   *) Autodetect FreeBSD3.
 244      [Ben Laurie]
 245
 246   *) Fix various bugs in Configure. This affects the following platforms:
 247      nextstep
 248      ncr-scde
 249      unixware-2.0
 250      unixware-2.0-pentium
 251      sco5-cc.
 252      [Ben Laurie]
 253
 254   *) Eliminate generated files from CVS. Reorder tests to regenerate files
 255      before they are needed.
 256      [Ben Laurie]
 257
 258   *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
 259      [Ben Laurie]
 260
 261  Changes between 0.9.1b and 0.9.1c
 262
 263   *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
 264      changed SSLeay to OpenSSL in version strings.
 265      [Ralf S. Engelschall]
 266
 267   *) Some fixups to the top-level documents.
 268      [Paul Sutton]
 269
 270   *) Fixed the nasty bug where rsaref.h was not found under compile-time
 271      because the symlink to include/ was missing.
 272      [Ralf S. Engelschall]
 273
 274   *) Incorporated the popular no-RSA/DSA-only patches
 275      which allow to compile a RSA-free SSLeay.
 276      [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
 277
 278   *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
 279      when "ssleay" is still not found.
 280      [Ralf S. Engelschall]
 281
 282   *) Added more platforms to Configure: Cray T3E, HPUX 11,
 283      [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
 284
 285   *) Updated the README file.
 286      [Ralf S. Engelschall]
 287
 288   *) Added various .cvsignore files in the CVS repository subdirs
 289      to make a "cvs update" really silent.
 290      [Ralf S. Engelschall]
 291
 292   *) Recompiled the error-definition header files and added
 293      missing symbols to the Win32 linker tables.
 294      [Ralf S. Engelschall]
 295
 296   *) Cleaned up the top-level documents;
 297      o new files: CHANGES and LICENSE
 298      o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
 299      o merged COPYRIGHT into LICENSE
 300      o removed obsolete TODO file
 301      o renamed MICROSOFT to INSTALL.W32
 302      [Ralf S. Engelschall]
 303
 304   *) Removed dummy files from the 0.9.1b source tree:
 305      crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
 306      crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
 307      crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
 308      crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
 309      util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
 310      [Ralf S. Engelschall]
 311
 312   *) Added various platform portability fixes.
 313      [Mark J. Cox]
 314
 315   *) The Genesis of the OpenSSL rpject:
 316      We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
 317      Young and Tim J. Hudson created while they were working for C2Net until
 318      summer 1998.
 319      [The OpenSSL Project]
 320
 321  Changes between 0.9.0b and 0.9.1b
 322
 323   *) Updated a few CA certificates under certs/
 324      [Eric A. Young]
 325
 326   *) Changed some BIGNUM api stuff.
 327      [Eric A. Young]
 328
 329   *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
 330      DGUX x86, Linux Alpha, etc.
 331      [Eric A. Young]
 332
 333   *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
 334      RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
 335      available).
 336      [Eric A. Young]
 337
 338   *) Add -strparse option to asn1pars program which parses nested
 339      binary structures
 340      [Dr Stephen Henson <shenson@bigfoot.com>]
 341
 342   *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
 343      [Eric A. Young]
 344
 345   *) DSA fix for "ca" program.
 346      [Eric A. Young]
 347
 348   *) Added "-genkey" option to "dsaparam" program.
 349      [Eric A. Young]
 350
 351   *) Added RIPE MD160 (rmd160) message digest.
 352      [Eric A. Young]
 353
 354   *) Added -a (all) option to "ssleay version" command.
 355      [Eric A. Young]
 356
 357   *) Added PLATFORM define which is the id given to Configure.
 358      [Eric A. Young]
 359
 360   *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
 361      [Eric A. Young]
 362
 363   *) Extended the ASN.1 parser routines.
 364      [Eric A. Young]
 365
 366   *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
 367      [Eric A. Young]
 368
 369   *) Added a BN_CTX to the BN library.
 370      [Eric A. Young]
 371
 372   *) Fixed the weak key values in DES library
 373      [Eric A. Young]
 374
 375   *) Changed API in EVP library for cipher aliases.
 376      [Eric A. Young]
 377
 378   *) Added support for RC2/64bit cipher.
 379      [Eric A. Young]
 380
 381   *) Converted the lhash library to the crypto/mem.c functions.
 382      [Eric A. Young]
 383
 384   *) Added more recognized ASN.1 object ids.
 385      [Eric A. Young]
 386
 387   *) Added more RSA padding checks for SSL/TLS.
 388      [Eric A. Young]
 389
 390   *) Added BIO proxy/filter functionality.
 391      [Eric A. Young]
 392
 393   *) Added extra_certs to SSL_CTX which can be used
 394      send extra CA certificates to the client in the CA cert chain sending
 395      process. It can be configured with SSL_CTX_add_extra_chain_cert().
 396      [Eric A. Young]
 397
 398   *) Now Fortezza is denied in the authentication phase because
 399      this is key exchange mechanism is not supported by SSLeay at all.
 400      [Eric A. Young]
 401
 402   *) Additional PKCS1 checks.
 403      [Eric A. Young]
 404
 405   *) Support the string "TLSv1" for all TLS v1 ciphers.
 406      [Eric A. Young]
 407
 408   *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
 409      ex_data index of the SSL context in the X509_STORE_CTX ex_data.
 410      [Eric A. Young]
 411
 412   *) Fixed a few memory leaks.
