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

 778
 779   *) Added various platform portability fixes.
 780      [Mark J. Cox]
 781
 782   *) The Genesis of the OpenSSL rpject:
 783      We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
 784      Young and Tim J. Hudson created while they were working for C2Net until
 785      summer 1998.
 786      [The OpenSSL Project]
 787
 788  Changes between 0.9.0b and 0.9.1b
 789
 790   *) Updated a few CA certificates under certs/

 792
 793   *) Changed some BIGNUM api stuff.
 794      [Eric A. Young]
 795
 796   *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
 797      DGUX x86, Linux Alpha, etc.
 798      [Eric A. Young]
 799
 800   *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
 801      RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
 802      available).
 803      [Eric A. Young]
 804
 805   *) Add -strparse option to asn1pars program which parses nested
 806      binary structures
 807      [Dr Stephen Henson <shenson@bigfoot.com>]
 808
 809   *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
 810      [Eric A. Young]
 811
 812   *) DSA fix for "ca" program.
 813      [Eric A. Young]
 814
 815   *) Added "-genkey" option to "dsaparam" program.
 816      [Eric A. Young]
 817
 818   *) Added RIPE MD160 (rmd160) message digest.
 819      [Eric A. Young]
 820
 821   *) Added -a (all) option to "ssleay version" command.
 822      [Eric A. Young]
 823
 824   *) Added PLATFORM define which is the id given to Configure.
 825      [Eric A. Young]
 826
 827   *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
 828      [Eric A. Young]
 829
 830   *) Extended the ASN.1 parser routines.
 831      [Eric A. Young]
 832
 833   *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
 834      [Eric A. Young]
 835
 836   *) Added a BN_CTX to the BN library.
 837      [Eric A. Young]
 838
 839   *) Fixed the weak key values in DES library
 840      [Eric A. Young]
 841
 842   *) Changed API in EVP library for cipher aliases.
 843      [Eric A. Young]
 844
 845   *) Added support for RC2/64bit cipher.
 846      [Eric A. Young]
