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

 669      [Ralf S. Engelschall]
 670
 671   *) Added various platform portability fixes.
 672      [Mark J. Cox]
 673
 674   *) The Genesis of the OpenSSL rpject:
 675      We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
 676      Young and Tim J. Hudson created while they were working for C2Net until
 677      summer 1998.
 678      [The OpenSSL Project]
 679
 680  Changes between 0.9.0b and 0.9.1b
 681
 682   *) Updated a few CA certificates under certs/

 684
 685   *) Changed some BIGNUM api stuff.
 686      [Eric A. Young]
 687
 688   *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
 689      DGUX x86, Linux Alpha, etc.
 690      [Eric A. Young]
 691
 692   *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
 693      RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
 694      available).
 695      [Eric A. Young]
 696
 697   *) Add -strparse option to asn1pars program which parses nested
 698      binary structures
 699      [Dr Stephen Henson <shenson@bigfoot.com>]
 700
 701   *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
 702      [Eric A. Young]
 703
 704   *) DSA fix for "ca" program.
 705      [Eric A. Young]
 706
 707   *) Added "-genkey" option to "dsaparam" program.
 708      [Eric A. Young]
 709
 710   *) Added RIPE MD160 (rmd160) message digest.
 711      [Eric A. Young]
 712
 713   *) Added -a (all) option to "ssleay version" command.
 714      [Eric A. Young]
 715
 716   *) Added PLATFORM define which is the id given to Configure.
 717      [Eric A. Young]
 718
 719   *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
 720      [Eric A. Young]
 721
 722   *) Extended the ASN.1 parser routines.
 723      [Eric A. Young]
 724
 725   *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
 726      [Eric A. Young]
 727
 728   *) Added a BN_CTX to the BN library.
 729      [Eric A. Young]
 730
 731   *) Fixed the weak key values in DES library
 732      [Eric A. Young]
 733
 734   *) Changed API in EVP library for cipher aliases.
 735      [Eric A. Young]
 736
 737   *) Added support for RC2/64bit cipher.
 738      [Eric A. Young]
 739
 740   *) Converted the lhash library to the crypto/mem.c functions.
 741      [Eric A. Young]
 742
 743   *) Added more recognized ASN.1 object ids.
 744      [Eric A. Young]
 745
 746   *) Added more RSA padding checks for SSL/TLS.
 747      [Eric A. Young]
 748
 749   *) Added BIO proxy/filter functionality.
 750      [Eric A. Young]
 751
 752   *) Added extra_certs to SSL_CTX which can be used
 753      send extra CA certificates to the client in the CA cert chain sending
 754      process. It can be configured with SSL_CTX_add_extra_chain_cert().
 755      [Eric A. Young]
 756
 757   *) Now Fortezza is denied in the authentication phase because
 758      this is key exchange mechanism is not supported by SSLeay at all.
 759      [Eric A. Young]
 760
 761   *) Additional PKCS1 checks.
 762      [Eric A. Young]
 763
 764   *) Support the string "TLSv1" for all TLS v1 ciphers.
 765      [Eric A. Young]
 766
 767   *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
 768      ex_data index of the SSL context in the X509_STORE_CTX ex_data.
 769      [Eric A. Young]
 770
 771   *) Fixed a few memory leaks.

 773
 774   *) Fixed various code and comment typos.
 775      [Eric A. Young]
 776
 777   *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
 778      bytes sent in the client random.
 779      [Edward Bishop <ebishop@spyglass.com>]
