175
176    * Minor bug fixes.
177
178
179Noteworthy changes in version 1.4.12 (2012-01-30)
180-------------------------------------------------
181
182    * GPG now accepts a space separated fingerprint as a user ID.
183      This allows to copy and paste the fingerprint from the key
184      listing.
185
186    * Removed support for the original HKP keyserver which is not
187      anymore used by any site.

198
199    * Made file locking more portable.
200
201    * Minor bug fixes.
202
203
204Noteworthy changes in version 1.4.11 (2010-10-18)
205-------------------------------------------------
206
207    * Bug fixes and portability changes.
208
209    * Minor changes for better interoperability with GnuPG-2.
210
211
212Noteworthy changes in version 1.4.10 (2009-09-02)
213-------------------------------------------------
214
215    * 2048 bit RSA keys are now generated by default.  The default
216      hash algorithm preferences has changed to prefer SHA-256 over
217      SHA-1.  2048 bit DSA keys are now generated to use a 256 bit
218      hash algorithm
219
220    * Support v2 OpenPGP cards.
221
222    * The algorithm to compute the SIG_ID status has been changed to
223      match the one from 2.0.10.
224
225    * Improved file locking.  Implemented it for W32.
226
227    * Fixed a memory leak which made imports of many keys very slow.
228
229    * Many smaller bug fixes.
230
231    * Support for the Camellia cipher (RFC-5581).
232
233    * Support for HKP keyservers over SSL ("HKPS").
234
235
236Noteworthy changes in version 1.4.9 (2008-03-26)
237------------------------------------------------
238
239    * Improved AES encryption performance by more than 20% (on ia32).
240      Decryption is also a bit faster.
241
242    * Fixed possible memory corruption bug in 1.4.8 while importing
243      OpenPGP keys. [CVE-2008-1530]
244
245
246Noteworthy changes in version 1.4.8 (2007-12-20)
247------------------------------------------------
248
249             *******************************************
250             * A decade of GnuPG: g10-0.0.0.tar.gz was *
251             *      released exactly 10 years ago.     *
252             *******************************************
253
254    * Changed the license to GPLv3.
255
256    * Improved detection of keyrings specified multiple times.
257
258    * Changes to better cope with broken keyservers.
259
260    * Minor bug fixes.
261
262    * The new OpenPGP standard is now complete, and has been published
263      as RFC-4880.  The GnuPG --openpgp mode (note this is not the
264      default) has been updated to match the new standard.  The
265      --rfc2440 option can be used to return to the older RFC-2440
266      behavior.  The main differences between the two are
267      "--enable-dsa2 --no-rfc2440-text --escape-from-lines
268      --require-cross-certification".
269
270    * By default (i.e. --gnupg mode), --require-cross-certification is
271      now on.  --rfc2440-text and --force-v3-sigs are now off.
272
273    * Allow encryption using legacy Elgamal sign+encrypt keys if
274      option --rfc2440 is used.
275
276    * Fixed the auto creation of the key stub for smartcards.
277
278    * Fixed a rare bug in decryption using the OpenPGP card.
279
280    * Fix RFC-4880 typo in the SHA-224 hash prefix.  Old SHA-224
281      signatures will continue to work.
282
283
284Noteworthy changes in version 1.4.7 (2007-03-05)
285------------------------------------------------
286
287    * By default, do not allow processing multiple plaintexts in a
288      single stream.  Many programs that called GnuPG were assuming
289      that GnuPG did not permit this, and were thus not using the
290      plaintext boundary status tags that GnuPG provides.  This change
291      makes GnuPG reject such messages by default which makes those
292      programs safe again.  --allow-multiple-messages returns to the
293      old behavior. [CVE-2007-1263].
294
295    * [W32] The environment variable LANGUAGE may be used to override
296      the language given by HKCU\Software\GNU\GnuPG:Lang.  The
297      language files "*.mo" are expected in a directory named
298      "gnupg.nls" below the directory with the gpg.exe binary.
299
300    * New --verify-option show-primary-uid-only.
301
302
303Noteworthy changes in version 1.4.6 (2006-12-06)
304------------------------------------------------
305
306    * Fixed a serious and exploitable bug in processing encrypted
307      packages. [CVE-2006-6235].
308
309    * Fixed a buffer overflow in gpg. [bug#728, CVE-2006-6169]
310
311    * Fixed a bug while decrypting certain compressed and encrypted
312      messages. [bug#537]
313
314    * Added --s2k-count to set the number of times passphrase mangling
315      is repeated.  The default is 65536 times.
316
317    * Added --passphrase-repeat to set the number of times GPG will
318      prompt for a new passphrase to be repeated.  This is useful to
319      help memorize a new passphrase.  The default is 1 repetition.
320
321    * Added a GPL license exception to the keyserver helper programs
322      gpgkeys_ldap, gpgkeys_curl, and gpgkeys_hkp, to clarify any
323      potential questions about the ability to distribute binaries
324      that link to the OpenSSL library.  GnuPG does not link directly
325      to OpenSSL, but libcurl (used for HKP, HTTP, and FTP) and
326      OpenLDAP (used for LDAP) may.  Note that this license exception
327      is considered a bug fix and is intended to forgive any
328      violations pertaining to this issue, including those that may
329      have occurred in the past.
330
331    * Man pages are now built from the same source as those of GnuPG-2.
332
333
334Noteworthy changes in version 1.4.5 (2006-08-01)
335------------------------------------------------
336
337    * Reverted check for valid standard handles under Windows.
338
339    * More DSA2 tweaks.
340
341    * Fixed a problem uploading certain keys to the smart card.
342
343    * Fixed 2 more possible memory allocation attacks.
344
345    * Added Norwegian translation.
346
347
348Noteworthy changes in version 1.4.4 (2006-06-25)
349------------------------------------------------
350
351    * User IDs are now capped at 2048 bytes.  This avoids a memory
352      allocation attack (see CVE-2006-3082).
353
354    * Added support for the SHA-224 hash.  Like the SHA-384 hash, it
355      is mainly useful when DSS (the US Digital Signature Standard)
356      compatibility is desired.
357
358    * Added support for the latest update to DSA keys and signatures.
359      This allows for larger keys than 1024 bits and hashes other than
360      SHA-1 and RIPEMD/160.  Note that not all OpenPGP implementations
361      can handle these new keys and signatures yet.  See
362      "--enable-dsa2" in the manual for more information.
363
364
365Noteworthy changes in version 1.4.3 (2006-04-03)
366------------------------------------------------
367
368    * If available, cURL-based keyserver helpers are built that can
369      retrieve keys using HKP or any protocol that cURL supports
370      (HTTP, HTTPS, FTP, FTPS, etc).  If cURL is not available, HKP
371      and HTTP are still supported using a built-in cURL emulator.  To
372      force building the old pre-cURL keyserver helpers, use the
373      configure option --enable-old-keyserver-helpers.  Note that none
374      of this affects finger or LDAP support, which are unchanged.
375      Note also that a future version of GnuPG will remove the old
376      keyserver helpers altogether.
377
378    * Implemented Public Key Association (PKA) signature verification.
379      This uses special DNS records and notation data to associate a
380      mail address with an OpenPGP key to prove that mail coming from
381      that address is legitimate without the need for a full trust
382      path to the signing key.
383
384    * When exporting subkeys, those specified with a key ID or
385      fingerpint and the '!' suffix are now merged into one keyblock.
386
387    * Added "gpg-zip", a program to create encrypted archives that can
388      interoperate with PGP Zip.
389
390    * Added support for signing subkey cross-certification "back
391      signatures".  Requiring cross-certification to be present is
392      currently off by default, but will be changed to on by default
393      in the future, once more keys use it.  A new "cross-certify"
394      command in the --edit-key menu can be used to update signing
395      subkeys to have cross-certification.
396
397    * The key cleaning options for --import-options and
398      --export-options have been further polished.  "import-clean" and
399      "export-clean" replace the older
400      import-clean-sigs/import-clean-uids and
401      export-clean-sigs/export-clean-uids option pairs.
402
403    * New "minimize" command in the --edit-key menu removes everything
404      that can be removed from a key, rendering it as small as
405      possible.  There are corresponding "export-minimal" and
406      "import-minimal" commands for --export-options and
407      --import-options.
408
409    * New --fetch-keys command to retrieve keys by specifying a URI.
410      This allows direct key retrieval from a web page or other
411      location that can be specified in a URI.  Available protocols
412      are HTTP and finger, plus anything that cURL supplies, if built
413      with cURL support.
414
415    * Files containing several signed messages are not allowed any
416      longer as there is no clean way to report the status of such
417      files back to the caller.  To partly revert to the old behaviour
418      the new option --allow-multisig-verification may be used.
419
420    * The keyserver helpers can now handle keys in either ASCII armor
421      or binary format.
422
423    * New auto-key-locate option that takes an ordered list of methods
424      to locate a key if it is not available at encryption time (-r or
425      --recipient).  Possible methods include "cert" (use DNS CERT as
426      per RFC2538bis, "pka" (use DNS PKA), "ldap" (consult the LDAP
427      server for the domain in question), "keyserver" (use the
428      currently defined keyserver), as well as arbitrary keyserver
429      URIs that will be contacted for the key.
430
431    * Able to retrieve keys using DNS CERT records as per RFC-4398.
432
433
434Noteworthy changes in version 1.4.2 (2005-07-26)
435------------------------------------------------
436
437    * New command "verify" in the card-edit menu to display
438      the Private-DO-3.  The Admin command has been enhanced to take
439      the optional arguments "on", "off" and "verify".  The latter may
440      be used to verify the Admin Pin without modifying data; this
441      allows displaying the Private-DO-4 with the "list" command.
442
443    * Rewrote large parts of the card code to optionally make use of a
444      running gpg-agent.  If --use-agent is being used and a gpg-agent
445      with enabled scdaemon is active, gpg will now divert all card
446      operations to that daemon.  This is required because both,
447      scdaemon and gpg require exclusive access to the card reader. By
448      delegating the work to scdaemon, both can peacefully coexist and
449      scdaemon is able to control the use of the reader.  Note that
450      this requires at least gnupg 1.9.17.
451
452    * Fixed a couple of problems with the card reader.
453
454    * Command completion is now available in the --edit-key and
455      --card-edit menus.  Filename completion is available at all
456      filename prompts.  Note that completion is only available if the
457      system provides a readline library.
458
459    * New experimental HKP keyserver helper that uses the cURL
460      library.  It is enabled via the configure option --with-libcurl
461      like the other (also experimental) cURL helpers.
462
463    * New key cleaning options that can be used to remove unusable
464      (expired, revoked) signatures from a key.  This is available via
465      the new "clean" command in --edit-key on a key by key basis, as
466      well as via the import-clean-sigs/import-clean-uids and
467      export-clean-sigs/export-clean-uids options for --import-options
468      and --export-options.  These are currently off by default, and
469      replace the import-unusable-sigs/export-unusable-sigs options
470      from version 1.4.1.
471
472    * New export option export-reset-subkey-passwd.
473
474    * New option --limit-card-insert-tries.
475
476
477Noteworthy changes in version 1.4.1 (2005-03-15)
478------------------------------------------------
479
480    * New --rfc2440-text option which controls how text is handled in
481      signatures.  This is in response to some problems seen with
482      certain PGP/MIME mail clients and GnuPG version 1.4.0.  More
483      details about this are available at
484      <http://lists.gnupg.org/pipermail/gnupg-users/2005-January/024408.html>.
485
486    * New "import-unusable-sigs" and "export-unusable-sigs" tags for
487      --import-options and --export-options.  These are off by default,
488      which causes GnuPG to not import or export key signatures that
489      are not usable (e.g. expired signatures).
490
491    * New experimental HTTP, HTTPS, FTP, and FTPS keyserver helper
492      that uses the cURL library <http://curl.haxx.se> to retrieve
493      keys.  This is disabled by default, but may be enabled with the
494      configure option --with-libcurl.  Without this option, the
495      existing HTTP code is used for HTTP, and HTTPS, FTP, and FTPS
496      are not supported.
497
498    * When running a --card-status or --card-edit and a public key is
499      available, missing secret key stubs will be created on the fly.
500      Details of the key are listed too.
501
502    * The implicit packet dumping in double verbose mode is now sent
503      to stderr and not to stdout.
504
505    * Added countermeasures against the Mister/Zuccherato CFB attack
506      <http://eprint.iacr.org/2005/033>.
507
508    * [W32] The algorithm for the default home directory changed:
509      First we look at the environment variable GNUPGHOME, if this one
510      is not set, we check whether the registry entry
511      {HKCU,HKLM}\Software\GNU\GnuPG:HomeDir has been set. If this
512      fails we use a GnuPG directory below the standard application
513      data directory (APPDATA) of the current user. Only in the case
514      that this directory cannot be determined, the old default of
515      c:\gnupg will be used.  The option --homedir still overrides all
516      of them.
517
518    * [W32] The locale selection under Windows changed. You need to
519      enter the locale in the registry at HKCU\Software\GNU\GnuPG:Lang.
520      For German you would use "de".  If it is not set, GnuPG falls
521      back to HKLM.  The languages files "*.mo" are expected in a
522      directory named "gnupg.nls" below the installation directory;
523      that directory must be stored in the registry at the same key as
524      above with the name "Install Directory".
525
526    * Add new --edit-key command "bkuptocard" to allow restoring a
527      card key from a backup.
528
529    * The "fetch" command of --card-edit now retrieves the key using
530      the default keyserver if no URL has been stored on the card.
531
532    * New configure option --enable-noexecstack.
533
534
535Noteworthy changes in version 1.4.0 (2004-12-16)
536------------------------------------------------
537
538    * See the file doc/highlights-1.4.txt for an overview of all
539      changes in respect to the 1.2 series.
540
541
542Noteworthy changes in version 1.3.93 (2004-12-14)
543-------------------------------------------------
544
545    * Ask the user to repeat a changed PIN.
546
547    * Switched to automake 1.9.  Minor big fixes.
548
549
550Noteworthy changes in version 1.3.92 (2004-10-28)
551-------------------------------------------------
552
553    * Added Russian man page. Thanks to Pawel I. Shajdo.
554
555    * libiconv is now used to support other character sets other than
556      UTF-8, Latin-1,-2 and KOI8-2.  The W32 version will only work
557      correctly when iconv.dll is installed on the system.  A binary
558      version is available at all GNU mirror sites under libiconv.
559
560    * gettext for Windows has been simplified.  The MO files are now
561      distributed UTF-8 encoded and gpg translates on the fly.
562
563
564Noteworthy changes in version 1.3.91 (2004-10-15)
565-------------------------------------------------
566
567    * A new configure option --enable-selinux-support disallows
568      processing of confidential files used by gpg (e.g. secring.gpg).
569      This helps writing ACLs for the SELinux kernel.
570
571    * Support for fetching keys via finger has been added.  This is
572      useful for setting a preferred keyserver URL like
573      "finger:wk@g10code.com".
574
575    * Timeout support has been added to the keyserver helpers.  This
576      allows users to set an upper limit on how long to wait for the
577      keyserver before giving up.
578
579    * New "direct" trust model where users can set key validity
580      directly if they do not want to participate in the web of trust.
581
582    * Minor bug fixes, code and string cleanups.
583
584
585Noteworthy changes in version 1.3.90 (2004-10-01)
586-------------------------------------------------
587
588    * Readline support at all prompts is now available if the system
589      provides a readline library.  The build time option
590      --without-readline may be used to disable this feature.
591
592    * Support for the OpenPGP smartcard is now enabled by default.
593      Use the option --disable-card-support to build without support
594      for smartcards.
595
596    * New command "addcardkey" in the key edit menu to add subkeys to
597      a smartcard. New command "keytocard" to transfer a key to a smartcard.
598      The serial number of the card is show in secret key listings.
599
600    * -K may now be used as an alias for --list-secret-keys.
601
602    * HTTP Basic authentication is now supported for all HKP and HTTP
603      keyserver functions, either through a proxy or via direct
604      access.
605
606
607Noteworthy changes in version 1.3.6 (2004-05-22)
608------------------------------------------------
609
610    * New --keyid-format option that selects short (99242560), long
611      (DB698D7199242560), 0xshort (0x99242560), or 0xlong
612      (0xDB698D7199242560) keyid displays.  This lets users tune the
613      display to what they prefer.
614
615    * The --list-options and --verify-options option
616      "show-long-keyids" has been removed since --keyid-format
617      obviates the need for them.
618
619    * Support for the old quasi-1991 partial length encoding has been
620      removed.
621
622    * The --export-all and --export-options include-non-rfc options
623      have been removed as superfluous since nonstandard V3 Elgamal
624      sign+encrypt keys have been removed.
625
626    * Preferred keyserver support has been added.  Users may set a
627      preferred keyserver via the --edit-key command "keyserver".  If
628      the --keyserver-option honor-keyserver-url is set (and it is by
629      default), then the preferred keyserver is used when refreshing
630      that key.
631
632    * The --sig-keyserver-url option can be used to inform signature
633      recipients where the signing key can be downloaded.  When
634      verifying the signature, if the signing key is not present, and
635      the keyserver options honor-keyserver-url and auto-key-retrieve
636      are set, this URL will be used to retrieve the key.
637
638    * Support for fetching keys via HTTP has been added.  This is
639      mainly useful for setting a preferred keyserver URL like
640      "http://www.jabberwocky.com/key.asc".
641
642    * New --ask-cert-level/--no-ask-cert-level option to turn on and
643      off the prompt for signature level when signing a key.  Defaults
644      to off.
645
646    * New --gpgconf-list command for internal use by the gpgconf
647      utility from gnupg 1.9.x.
648
649
650Noteworthy changes in version 1.3.5 (2004-02-26)
651------------------------------------------------
652
653    * New --min-cert-level option to disregard key signatures that are
654      under a specified level.  Defaults to 2 (i.e. discard 0x11
655      signatures).
656
657    * New --max-output option to limit the amount of plaintext output
658      generated by GnuPG.  This option can be used by programs which
659      call GnuPG to process messages that may result in plaintext
660      larger than the calling program is prepared to handle.  This is
661      sometimes called a "Decompression Bomb".
662
663    * New --list-config command for frontends and other programs that
664      call GnuPG.  See doc/DETAILS for the specifics of this.
665
666    * Some performance improvements with large keyrings.  See the
667      build time option --enable-key-cache=SIZE in the README file for
668      details.
669
670    * Some portability fixes for the OpenBSD/i386, HPPA, and AIX
671      platforms.
672
673    * New keyserver-option "http-proxy" to specify which proxy to use
674      in the config file without using environment variables.
675
676    * Added support for storing, retrieving, and searching for keys in
677      LDAP servers.  Note that this is different than the "LDAP
678      keyserver" which was already (and remains) supported.
679
680    * Added support for TLS and LDAPS session encryption for LDAP.
681
682    * --show-session-key/--override-session-key now works with
683      --symmetric messages.
684
685    * The configure options --enable-rsa and --disable-rsa can now be
686      used to enable or disable the RSA algorithm.  This can be useful
687      for embedded use where space is tight.  --enable-minimal
688      includes --disable-rsa.  RSA is enabled by default.
689
690    * The last support for Elgamal sign+encrypt keys has been removed.
691
692
693Noteworthy changes in version 1.3.4 (2003-11-27)
694------------------------------------------------
695
696    * Added support for BZIP2 compression.  This should be considered
697      experimental, and is only available if the libbzip2 library
698      <http://sources.redhat.com/bzip2/> is installed.
699
700    * Added the ability to handle messages that can be decrypted with
701      either a passphrase or a secret key.  These messages may be
702      generated with --symmetric --encrypt or --symmetric --sign
703      --encrypt.
704
705    * The config file search has been enhanced to try for less
706      specific filename matches before giving up.  For example,
707      version 1.3.4 will try for gpg.conf-1.3.4, gpg.conf-1.3, and
708      gpg.conf-1 before falling back to the regular gpg.conf file.
709
710    * Fixed a format string bug in the HKP keyserver handler.
711
712    * Support for Elgamal sign+encrypt keys has been removed.  Old
713      signatures may still be verified, and existing encrypted
714      messages may still be decrypted, but no new signatures may be
715      issued by, and no new messages will be encrypted to, these keys.
716
717
718Noteworthy changes in version 1.3.3 (2003-10-10)
719------------------------------------------------
720
721    * Basic support for the OpenPGP card.  New commands --card-status,
722      --card-edit, --change-pin and the configuration options
723      --reader-port, --ctapi-driver, --pcsc-driver, and --disable-ccid.
724
725    * Full (read/write) support for the SHA-256 hash has been added.
726
727    * Support for the TIGER/192 hash has been dropped.  This should
728      not be interpreted as a statement as to the strength of
729      TIGER/192 - rather, the upcoming revision to the OpenPGP
730      standard removes support for several unused (or mostly unused)
731      hashes.
732
733    * Revoked or expired user IDs are now skipped when selecting keys
734      for encryption.  Specifying a key by the key ID overrides this
735      check and allows the selection of any key.
736
737    * Note that --no-mangle-dos-filenames is now the default.  If you
738      are upgrading from a 1.2.x version of GnuPG, and are running a
739      very old version of Windows that has the 8.3 filename limit, you
740      may need to change this.
741
742    * Multiple "Comment:" lines in armored output are now allowed.
743
744    * New --list-options option.  This option takes a list of
745      arguments that allows the user to customize exactly what key
746      listings (including the --edit-key listing) look like, enabling
747      or disabling things such as photo display, policy URL, preferred
748      keyserver URL, or notation display, long or short keyIDs,
749      calculated validity for each user ID, etc.  See the manual for
750      the complete list of list-options.
751
752    * New --verify-options option.  This option takes a list of
753      arguments that allows the user to customize exactly what happens
754      during signature verification, enabling or disabling things such
755      as photo display, policy URL, preferred keyserver URL, or
756      notation display, long or short keyIDs, calculated validity for
757      each user ID, etc.  See the manual for the complete list of
758      verify-options.
759
760    * New --sig-keyserver-url to embed a "where to get my key"
761      subpacket into a signature.
762
763    * The options --show-photos, --show-policy-url, --show-notation,
764      and --show-keyring are all deprecated in favor of those
765      arguments to --list-options and --verify-options.  The new
766      method is more flexible since a user can specify (for example)
767      showing photos during sig verification, but not in key listings.
768
769    * The complete fingerprint of the key that made a given key
770      certification is now available in the --with-colons output.  For
771      technical reasons, this is only available when running with
772      --no-sig-cache set.  See doc/DETAILS for the specifics of this.
773
774    * IPv6 support for HKP keyserver access.  IPv6 for LDAP keyserver
775      access is also supported, but is dependent on the LDAP library
776      used.
777
778    * To simplify running both the stable (1.2.x) and development
779      (1.3.x) versions of GnuPG, the development version will try to
780      load the options file gpg.conf-VERSION (e.g. gpg.conf-1.3.3 for
781      this release) before falling back to the regular gpg.conf file.
782
783    * Two new %-expandos for use in notation and policy URLs.  "%g"
784      expands to the fingerprint of the key making the signature
785      (which might be a subkey), and "%p" expands to the fingerprint
786      of the primary key that owns the key making the signature.
787
788    * New "tru" record in --with-colons --list-keys listings.  It
789      shows the status of the trust database that was used to
790      calculate the key validity in the listings.  See doc/DETAILS for
791      the specifics of this.
792
793    * New REVKEYSIG status tag for --status-fd.  It indicates a valid
794      signature that was issued by a revoked key.  See doc/DETAILS for
795      the specifics of this.
796
797    * A number of portability changes to make building GnuPG on
798      less-common platforms easier.
799
800
801Noteworthy changes in version 1.3.2 (2003-05-27)
802------------------------------------------------
803
804    * New "--gnupg" option (set by default) that disables --openpgp,
805      and the various --pgpX emulation options.  This replaces
806      --no-openpgp, and --no-pgpX, and also means that GnuPG has
807      finally grown a --gnupg option to make GnuPG act like GnuPG.
808
809    * A bug in key validation has been fixed.  This bug only affects
810      keys with more than one user ID (photo IDs do not count here),
811      and results in all user IDs on a given key being treated with
812      the validity of the most-valid user ID on that key.
813
814    * Notation names that do not contain a '@' are no longer allowed
815      unless --expert is set.  This is to help prevent pollution of
816      the (as yet unused) IETF notation namespace.
817
818    * Multiple trust models are now supported via the --trust-model
819      option.  The options are "pgp" (web-of-trust plus trust
820      signatures), "classic" (web-of-trust only), and "always"
821      (identical to the --always-trust option).
822
823    * The --personal-{cipher|digest|compression}-preferences are now
824      consulted to get default algorithms before resorting to the
825      last-ditch defaults of --s2k-cipher-algo, SHA1, and ZIP
826      respectively.  This allows a user to set algorithms to use in a
827      safe manner so they are used when legal to do so, without
828      forcing them on for all messages.
829
830    * New --primary-keyring option to designate the keyring that the
831      user wants new keys imported into.
832
833    * --s2k-digest-algo is now used for all password mangling.
834      Earlier versions used both --s2k-digest-algo and --digest-algo
835      for passphrase mangling.
836
837    * Handling of --hidden-recipient or --throw-keyid messages is now
838      easier - the user only needs to give their passphrase once, and
839      GnuPG will try it against all of the available secret keys.
840
841    * Care is taken to prevent compiler optimization from removing
842      memory wiping code.
843
844    * New option --no-mangle-dos-filenames so that filenames are not
845      truncated in the W32 version.
846
847    * A "convert-from-106" script has been added.  This is a simple
848      script that automates the conversion from a 1.0.6 or earlier
849      version of GnuPG to a 1.0.7 or later version.
850
851    * Disabled keys are now skipped when selecting keys for
852      encryption.  If you are using the --with-colons key listings to
853      detect disabled keys, please see doc/DETAILS for a minor format
854      change in this release.
855
856    * Minor trustdb changes to make the trust calculations match
857      common usage.
858
859    * New command "revuid" in the --edit-key menu to revoke a user ID.
860      This is a simpler interface to the old method (which still
861      works) of revoking the user ID self-signature.
862
863    * Status VALIDSIG does now also print the primary key's
864      fingerprint, as well as the signature version, pubkey algorithm,
865      hash algorithm, and signature class.
866
867    * Add read-only support for the SHA-256 hash, and optional
868      read-only support for the SHA-384 and SHA-512 hashes.
869
870    * New option --enable-progress-filter for use with frontends.
871
872    * DNS SRV records are used in HKP keyserver lookups to allow
873      administrators to load balance and select keyserver ports
874      automatically.  This is as specified in
875      draft-shaw-openpgp-hkp-00.txt.
876
877    * When using the "keyid!" syntax during a key export, only that
878      specified key is exported.  If the key in question is a subkey,
879      the primary key plus only that subkey is exported.
880
881    * configure --disable-xxx options to disable individual algorithms
882      at build time.  This can be used to build a smaller gpg binary
883      for embedded uses where space is tight.  See the README file for
884      the algorithms that can be used with this option, or use
885      --enable-minimal to build the smallest gpg possible (disables
886      all optional algorithms, disables keyserver access, and disables
887      photo IDs).
888
889    * The keyserver no-modify flag on a key can now be displayed and
890      modified.
891
892    * Note that the TIGER/192 digest algorithm is in the process of
893      being dropped from the OpenPGP standard.  While this release of
894      GnuPG still contains it, it is disabled by default.  To ensure
895      you will still be able to use your messages with future versions
896      of GnuPG and other OpenPGP programs, please do not use this
897      algorithm.
898
899
900Noteworthy changes in version 1.3.1 (2002-11-12)
901------------------------------------------------
902
903    * Trust signature support.  This is based on the Maurer trust
904      model where a user can specify the trust level along with the
905      signature with multiple levels so users can delegate
906      certification ability to other users, possibly restricted by a
907      regular expression on the user ID.  Note that full trust
908      signature support requires a regular expression parsing library.
909      The regexp code from glibc 2.3.1 is included for those platforms
910      that don't have working regexp functions available.  The
911      configure option --disable-regex may be used to disable any
912      regular expression code, which will make GnuPG ignore any trust
913      signature with a regular expression included.
914
915    * Two new commands --hidden-recipient (-R) and --hidden-encrypt-to
916      encrypt to a user, but hide the identity of that user.  This is
917      the same functionality as --throw-keyid, but can be used on a
918      per-user basis.
919
920    * Full algorithm names (e.g. "3DES", "SHA1", "ZIP") can now be
921      used interchangeably with the short algorithm names (e.g. "S2",
922      "H2", "Z1") anywhere algorithm names are used in GnuPG.
923
924
925Noteworthy changes in version 1.3.0 (2002-10-18)
926------------------------------------------------
927
928    * The last piece of internal keyserver support has been removed,
929      and now all keyserver access is done via the keyserver plugins.
930      There is also a newer keyserver protocol used between GnuPG and
931      the plugins, so plugins from earlier versions of GnuPG may not
932      work properly.
933
934    * The HKP keyserver plugin supports the new machine-readable key
935      listing format for those keyservers that provide it.
936
937    * When using a HKP keyserver with multiple DNS records (such as
938      wwwkeys.pgp.net which has the addresses of multiple servers
939      around the world), try all records until one succeeds.  Note
940      that it depends on the LDAP library used whether the LDAP
941      keyserver plugin does this as well.
942
943    * The library dependencies for OpenLDAP seem to change fairly
944      frequently, and GnuPG's configure script cannot guess all the
945      combinations.  Use ./configure LDAPLIBS="-L libdir -l libs" to
946      override the script and use the libraries selected.
947
948    * Secret keys generated with --export-secret-subkeys are now
949      indicated in key listings with a '#' after the "sec", and in
950      --with-colons listings by showing no capabilities (no lowercase
951      characters).
952
953    * --trusted-key has been un-obsoleted, as it is useful for adding
954      ultimately trusted keys from the config file.  It is identical
955      to using --edit and "trust" to change a key to ultimately
956      trusted.
957
958    * Translations other than de are no longer distributed with the
959      development branch.  This is due to the frequent text changes
960      during development, which cause the translations to rapidly go
961      out of date.
962
963
964Noteworthy changes in version 1.1.92 (2002-09-11)
965-------------------------------------------------
966
967    * [IMPORTANT] The default configuration file is now
968      ~/.gnupg/gpg.conf.  If an old ~/.gnupg/options is found it will
969      still be used.  This change is required to have a more
970      consistent naming scheme with forthcoming tools.
971
972    * The use of MDCs have increased.  A MDC will be used if the
973      recipients directly request it, if the recipients have AES,
974      AES192, AES256, or TWOFISH in their cipher preferences, or if
975      the chosen cipher has a blocksize not equal to 64 bits
976      (currently this is also AES, AES192, AES256, and TWOFISH).
977
978    * GnuPG will no longer automatically disable compression when
979      processing an already-compressed file unless a MDC is being
980      used.  This is to give the message a certain amount of
981      resistance to the chosen-ciphertext attack while communicating
982      with other programs (most commonly PGP earlier than version 7.x)
983      that do not support MDCs.
984
985    * The option --interactive now has the desired effect when
986      importing keys.
987
988    * The file permission and ownership checks on files have been
989      clarified.  Specifically, the homedir (usually ~/.gnupg) is
990      checked to protect everything within it.  If the user specifies
991      keyrings outside this homedir, they are presumed to be shared
992      keyrings and therefore *not* checked.  Configuration files
993      specified with the --options option and the IDEA cipher
994      extension specified with --load-extension are checked, along
995      with their enclosing directories.
996
997    * The configure option --with-static-rnd=auto allows to build gpg
998      with all available entropy gathering modules included.  At
999      runtime the best usable one will be selected from the list
1000      linux, egd, unix.  This is also the default for systems lacking
1001      a /dev/random device.
1002
1003    * The default character set is now taken from the current locale;
1004      it can still be overridden by the --charset option.  Using the
1005      option -vvv shows the used character set.
1006
1007    * [REMOVED] --emulate-checksum-bug and --emulate-3des-s2k-bug have
1008      been removed.
1009
1010
1011Noteworthy changes in version 1.1.91 (2002-08-04)
1012-------------------------------------------------
1013
1014    * All modules are now linked statically; the --load-extension
1015      option is in general not useful anymore.  The only exception is
1016      to specify the deprecated idea cipher.
1017
1018    * The IDEA plugin has changed.  Previous versions of the IDEA
1019      plugin will no longer work with GnuPG.  However, the current
1020      version of the plugin will work with earlier GnuPG versions.
1021
1022    * When using --batch with one of the --delete-key commands, the
1023      key must be specified by fingerprint.  See the man page for
1024      details.
1025
1026    * There are now various ways to restrict the ability GnuPG has to
1027      exec external programs (for the keyserver helpers or photo ID
1028      viewers).  Read the README file for the complete list.
1029
1030    * New export option to leave off attribute packets (photo IDs)
1031      during export.  This is useful when exporting to HKP keyservers
1032      which do not understand attribute packets.
1033
1034    * New import option to repair during import the HKP keyserver
1035      mangling multiple subkeys bug.  Note that this cannot completely
1036      repair the damaged key as some crucial data is removed by the
1037      keyserver, but it does at least give you back one subkey.  This
1038      is on by default for keyserver --recv-keys, and off by default
1039      for regular --import.
1040
1041    * The keyserver helper programs now live in
1042      /usr/[local/]libexec/gnupg by default.  If you are upgrading
1043      from 1.0.7, you might want to delete your old copies in
1044      /usr/[local/]bin.  If you use an OS that does not use libexec
1045      for whatever reason, use configure --libexecdir=/usr/local/lib
1046      to place the keyserver helpers there.
1047
1048    * The LDAP keyserver handler now works properly with very old
1049      (version 1) LDAP keyservers.
1050
1051
1052Noteworthy changes in version 1.1.90 (2002-07-01)
1053-------------------------------------------------
1054
1055    * New commands: --personal-cipher-preferences,
1056      --personal-digest-preferences, and
1057      --personal-compress-preferences allow the user to specify which
1058      algorithms are to be preferred.  Note that this does not permit
1059      using an algorithm that is not present in the recipient's
1060      preferences (which would violate the OpenPGP standard).  This
1061      just allows sorting the preferences differently.
1062
1063    * New "group" command to refer to several keys with one name.
1064
1065    * A warning is issued if the user forces the use of an algorithm
1066      that is not listed in the recipient's preferences.
1067
1068    * Full revocation key (aka "designated revoker") support.
1069
1070    * The preferred hash algorithms on a key are consulted when
1071      encrypting a signed message to that key.  Note that this is
1072      disabled by default by a SHA1 preference in
1073      --personal-digest-preferences.
1074
1075    * --cert-digest-algo allows the user to specify the hash algorithm
1076      to use when signing a key rather than the default SHA1 (or MD5
1077      for PGP2 keys).  Do not use this feature unless you fully
1078      understand the implications of this.
1079
1080    * --pgp7 mode automatically sets all necessary options to ensure
1081      that the resulting message will be usable by a user of PGP 7.x.
1082
1083    * New --attribute-fd command for frontends and scripts to get the
1084      contents of attribute packets (i.e. photos)
1085
1086    * In expert mode, the user can now re-sign a v3 key with a v4
1087      self-signature.  This does not change the v3 key into a v4 key,
1088      but it does allow the user to use preferences, primary ID flags,
1089      etc.
1090
1091    * Significantly improved photo ID support on non-unixlike
1092      platforms.
1093
1094    * The version number has jumped ahead to 1.1.90 to skip over the
1095      old version 1.1 and to get ready for the upcoming 1.2.
1096
1097    * ElGamal sign and encrypt is not anymore allowed in the key
1098      generation dialog unless in expert mode.  RSA sign and encrypt
1099      has been added with the same restrictions.
1100
1101    * [W32] Keyserver access does work with Windows NT.
1102
1103
1104Noteworthy changes in version 1.0.7 (2002-04-29)
1105------------------------------------------------
1106
1107    * Secret keys are now stored and exported in a new format which
1108      uses SHA-1 for integrity checks.  This format renders the
1109      Rosa/Klima attack useless.  Other OpenPGP implementations might
1110      not yet support this, so the option --simple-sk-checksum creates
1111      the old vulnerable format.
1112
1113    * The default cipher algorithm for encryption is now CAST5,
1114      default hash algorithm is SHA-1.  This will give us better
1115      interoperability with other OpenPGP implementations.
1116
1117    * Symmetric encrypted messages now use a fixed file size if
1118      possible.  This is a tradeoff: it breaks PGP 5, but fixes PGP 2,
1119      6, and 7.  Note this was only an issue with RFC-1991 style
1120      symmetric messages.
1121
1122    * Photographic user ID support.  This uses an external program to
1123      view the images.
1124
1125    * Enhanced keyserver support via keyserver "plugins".  GnuPG comes
1126      with plugins for the NAI LDAP keyserver as well as the HKP email
1127      keyserver.  It retains internal support for the HKP HTTP
1128      keyserver.
1129
1130    * Nonrevocable signatures are now supported.  If a user signs a
1131      key nonrevocably, this signature cannot be taken back so be
1132      careful!
1133
1134    * Multiple signature classes are usable when signing a key to
1135      specify how carefully the key information (fingerprint, photo
1136      ID, etc) was checked.
1137
1138    * --pgp2 mode automatically sets all necessary options to ensure
1139      that the resulting message will be usable by a user of PGP 2.x.
1140
1141    * --pgp6 mode automatically sets all necessary options to ensure
1142      that the resulting message will be usable by a user of PGP 6.x.
1143
1144    * Signatures may now be given an expiration date.  When signing a
1145      key with an expiration date, the user is prompted whether they
1146      want their signature to expire at the same time.
1147
1148    * Revocation keys (designated revokers) are now supported if
1149      present.  There is currently no way to designate new keys as
1150      designated revokers.
1151
1152    * Permissions on the .gnupg directory and its files are checked
1153      for safety.
1154
1155    * --expert mode enables certain silly things such as signing a
1156      revoked user id, expired key, or revoked key.
1157
1158    * Some fixes to build cleanly under Cygwin32.
1159
1160    * New tool gpgsplit to split OpenPGP data formats into packets.
1161
1162    * New option --preserve-permissions.
1163
1164    * Subkeys created in the future are not used for encryption or
1165      signing unless the new option --ignore-valid-from is used.
1166
1167    * Revoked user-IDs are not listed unless signatures are listed too
1168      or we are in verbose mode.
1169
1170    * There is no default comment string with ascii armors anymore
1171      except for revocation certificates and --enarmor mode.
1172
1173    * The command "primary" in the edit menu can be used to change the
1174      primary UID, "setpref" and "updpref" can be used to change the
1175      preferences.
1176
1177    * Fixed the preference handling; since 1.0.5 they were erroneously
1178      matched against against the latest user ID and not the given one.
1179
1180    * RSA key generation.
1181
1182    * Merged Stefan's patches for RISC OS in.  See comments in
1183      scripts/build-riscos.
1184
1185    * It is now possible to sign and conventional encrypt a message (-cs).
1186
1187    * The MDC feature flag is supported and can be set by using
1188      the "updpref" edit command.
1189
1190    * The status messages GOODSIG and BADSIG are now returning the primary
1191      UID, encoded using %XX escaping (but with spaces left as spaces,
1192      so that it should not break too much)
1193
1194    * Support for GDBM based keyrings has been removed.
1195
1196    * The entire keyring management has been revamped.
1197
1198    * The way signature stati are store has changed so that v3
1199      signatures can be supported. To increase the speed of many
1200      operations for existing keyrings you can use the new
1201      --rebuild-keydb-caches command.
1202
1203    * The entire key validation process (trustdb) has been revamped.
1204      See the man page entries for --update-trustdb, --check-trustdb
1205      and --no-auto-check-trustdb.
1206
1207    * --trusted-keys is again obsolete, --edit can be used to set the
1208      ownertrust of any key to ultimately trusted.
1209
1210    * A subkey is never used to sign keys.
1211
1212    * Read only keyrings are now handled as expected.
1213
1214
1215Noteworthy changes in version 1.0.6 (2001-05-29)
1216------------------------------------------------
1217
1218    * Security fix for a format string bug in the tty code.
1219
1220    * Fixed format string bugs in all PO files.
1221
1222    * Removed Russian translation due to too many bugs.  The FTP
1223      server has an unofficial but better translation in the contrib
1224      directory.
1225
1226    * Fixed expire time calculation and keyserver access.
1227
1228    * The usual set of minor bug fixes and enhancements.
1229
1230    * non-writable keyrings are now correctly handled.
1231
1232
1233Noteworthy changes in version 1.0.5 (2001-04-29)
1234------------------------------------------------
1235
1236    * WARNING: The semantics of --verify have changed to address a
1237      problem with detached signature detection. --verify now ignores
1238      signed material given on stdin unless this is requested by using
1239      a "-" as the name for the file with the signed material.  Please
1240      check all your detached signature handling applications and make
1241      sure that they don't pipe the signed material to stdin without
1242      using a filename together with "-" on the the command line.
1243
1244    * WARNING: Corrected hash calculation for input data larger than
1245      512M - it was just wrong, so you might notice bad signature in
1246      some very big files.  It may be wise to keep an old copy of
1247      GnuPG around.
1248
1249    * Secret keys are no longer imported unless you use the new option
1250      --allow-secret-key-import.  This is a kludge and future versions will
1251      handle it in another way.
1252
1253    * New command "showpref" in the --edit-key menu to show an easier
1254      to understand preference listing.
1255
1256    * There is now the notation of a primary user ID.  For example, it
1257      is printed with a signature verification as the first user ID;
1258      revoked user IDs are not printed there anymore.  In general the
1259      primary user ID is the one with the latest self-signature.
1260
1261    * New --charset=utf-8 to bypass all internal conversions.
1262
1263    * Large File Support (LFS) is now working.
1264
1265    * New options: --ignore-crc-error, --no-sig-create-check,
1266      --no-sig-cache, --fixed-list-mode, --no-expensive-trust-checks,
1267      --enable-special-filenames and --use-agent.  See man page.
1268
1269    * New command --pipemode, which can be used to run gpg as a
1270      co-process.  Currently only the verification of detached
1271      signatures are working.  See doc/DETAILS.
1272
1273    * Keyserver support for the W32 version.
1274
1275    * Rewritten key selection code so that GnuPG can better cope with
1276      multiple subkeys, expire dates and so.  The drawback is that it
1277      is slower.
1278
1279    * A whole lot of bug fixes.
1280
1281    * The verification status of self-signatures are now cached. To
1282      increase the speed of key list operations for existing keys you
1283      can do the following in your GnuPG homedir (~/.gnupg):
1284         cp pubring.gpg pubring.gpg.save && gpg --export-all >x && \
1285         rm pubring.gpg && gpg --import x
1286      Only v4 keys (i.e not the old RSA keys) benefit from this caching.
1287
1288    * New translations: Estonian, Turkish.
1289
1290
1291Noteworthy changes in version 1.0.4 (2000-10-17)
1292------------------------------------------------
1293
1294    * Fixed a serious bug which could lead to false signature verification
1295      results when more than one signature is fed to gpg.  This is the
1296      primary reason for releasing this version.
1297
1298    * New utility gpgv which is a stripped down version of gpg to
1299      be used to verify signatures against a list of trusted keys.
1300
1301    * Rijndael (AES) is now supported and listed with top preference.
1302
1303    * --with-colons now works with --print-md[s].
1304
1305Noteworthy changes in version 1.0.3 (2000-09-18)
1306------------------------------------------------
1307
1308    * Fixed problems with piping to/from other MS-Windows software
1309
1310    * Expiration time of the primary key can be changed again.
1311
1312    * Revoked user IDs are now marked in the output of --list-key
1313
1314    * New options --show-session-key and --override-session-key
1315      to help the British folks to somewhat minimize the danger
1316      of this Orwellian RIP bill.
1317
1318    * New options --merge-only and --try-all-secrets.
1319
1320    * New configuration option --with-egd-socket.
1321
1322    * The --trusted-key option is back after it left us with 0.9.5
1323
1324    * RSA is supported. Key generation does not yet work but will come
1325      soon.
1326
1327    * CAST5 and SHA-1 are now the default algorithms to protect the key
1328      and for symmetric-only encryption. This should solve a couple
1329      of compatibility problems because the old algorithms are optional
1330      according to RFC2440
1331
1332    * Twofish and MDC enhanced encryption is now used.  PGP 7 supports
1333      this.  Older versions of GnuPG don't support it, so they should be
1334      upgraded to at least 1.0.2
1335
1336
1337Noteworthy changes in version 1.0.2 (2000-07-12)
1338----------------------------------------------
1339
1340    * Fixed expiration handling of encryption keys.
1341
1342    * Add an experimental feature to do unattended key generation.
1343
1344    * The user is now asked for the reason of revocation as required
1345      by the new OpenPGP draft.
1346
1347    * There is a ~/.gnupg/random_seed file now which saves the
1348      state of the internal RNG and increases system performance
1349      somewhat.  This way the full entropy source is only used in
1350      cases were it is really required.
1351      Use the option --no-random-seed-file to disable this feature.
1352
1353    * New options --ignore-time-conflict and --lock-never.
1354
1355    * Some fixes for the W32 version.
1356
1357    * The entropy.dll is not anymore used by the W32 version but replaced
1358      by code derived from Cryptlib.
1359
1360    * Encryption is now much faster: About 2 times for 1k bit keys
1361      and 8 times for 4k keys.
1362
1363    * New encryption keys are generated in a way which allows a much
1364      faster decryption.
1365
1366    * New command --export-secret-subkeys which outputs the
1367      the _primary_ key with it's secret parts deleted.  This is
1368      useful for automated decryption/signature creation as it
1369      allows to keep the real secret primary key offline and
1370      thereby protecting the key certificates and allowing to
1371      create revocations for the subkeys.  See the FAQ for a
1372      procedure to install such secret keys.
1373
1374    * Keygeneration now writes to the first writeable keyring or
1375      as default to the one in the homedirectory.  Prior versions
1376      ignored all --keyring options.
1377
1378    * New option --command-fd to take user input from a file descriptor;
1379      to be used with --status-fd by software which uses GnuPG as a backend.
1380
1381    * There is a new status PROGRESS which is used to show progress during
1382      key generation.
1383
1384    * Support for the new MDC encryption packets.  To create them either
1385      --force-mdc must be use or cipher algorithm with a blocksize other
1386      than 64 bits is to be used.  --openpgp currently disables MDC packets
1387      entirely.  This option should not yet be used.
1388
1389    * New option --no-auto-key-retrieve to disable retrieving of
1390      a missing public key from a keyserver, when a keyserver has been set.
1391
1392    * Danish translation
1393
1394Noteworthy changes in version 1.0.1 (1999-12-16)
1395-----------------------------------
1396
1397    * New command --verify-files.  New option --fast-list-mode.
1398
1399    * $http_proxy is now used when --honor-http-proxy is set.
1400
1401    * Fixed some minor bugs and the problem with conventional encrypted
1402      packets which did use the gpg v3 partial length headers.
1403
1404    * Add Indonesian and Portugese translations.
1405
1406    * Fixed a bug with symmetric-only encryption using the non-default 3DES.
1407      The option --emulate-3des-s2k-bug may be used to decrypt documents
1408      which have been encrypted this way; this should be done immediately
1409      as this workaround will be remove in 1.1
1410
1411    * Can now handle (but not display) PGP's photo IDs. I don't know the
1412      format of that packet but after stripping a few bytes from the start
1413      it looks like a JPEG (at least my test data).  Handling of this
1414      package is required because otherwise it would mix up the
1415      self signatures and you can't import those keys.
1416
1417    * Passing non-ascii user IDs on the commandline should now work in all
1418      cases.
1419
1420    * New keys are now generated with an additional preference to Blowfish.
1421
1422    * Removed the GNU Privacy Handbook from the distribution as it will go
1423      into a separate one.
1424
1425
1426Noteworthy changes in version 1.0.0 (1999-09-07)
1427-----------------------------------
1428
1429    * Add a very preliminary version of the GNU Privacy Handbook to
1430      the distribution (lynx doc/gph/index.html).
1431
1432    * Changed the version number to GnuPG 2001 ;-)
1433
1434
1435Noteworthy changes in version 0.9.11
1436------------------------------------
1437
1438    * UTF-8 strings are now correctly printed (if --charset is set correctly).
1439      Output of --with-colons remains C-style escaped UTF-8.
1440
1441    * Workaround for a problem with PGP 5 detached signature in textmode.
1442
1443    * Fixed a problem when importing new subkeys (duplicated signatures).
1444
1445Noteworthy changes in version 0.9.10
1446------------------------------------
1447
1448    * Some strange new options to help pgpgpg
1449
1450    * Cleaned up the dox a bit.
1451
1452
1453Noteworthy changes in version 0.9.9
1454-----------------------------------
1455
1456    * New options --[no-]utf8-strings.
1457
1458    * New edit-menu commands "enable" and "disable" for entire keys.
1459
1460    * You will be asked for a filename if gpg cannot deduce one.
1461
1462    * Changes to support libtool which is needed for the development
1463      of libgcrypt.
1464
1465    * New script tools/lspgpot to help transferring assigned
1466      trustvalues from PGP to GnuPG.
1467
1468    * New commands --lsign-key and made --sign-key a shortcut for --edit
1469      and sign.
1470
1471    * New options (#122--126 ;-) --[no-]default-recipient[-self],
1472      --disable-{cipher,pubkey}-algo. See the man page.
1473
1474    * Enhanced info output in case of multiple recipients and fixed exit code.
1475
1476    * New option --allow-non-selfsigned-uid to work around a problem with
1477      the German IN way of separating signing and encryption keys.
1478
1479
1480Noteworthy changes in version 0.9.8
1481-----------------------------------
1482
1483    * New subcommand "delsig" in the edit menu.
1484
1485    * The name of the output file is not anymore the one which is
1486      embedded in the processed message, but the used filename with
1487      the extension stripped.  To revert to the old behaviour you can
1488      use the option --use-embedded-filename.
1489
1490    * Another hack to cope with pgp2 generated detached signatures.
1491
1492    * latin-2 character set works (--charset=iso-8859-2).
1493
1494    * New option --with-key-data to list the public key parameters.
1495      New option -N to insert notations and a --set-policy-url.
1496      A couple of other options to allow reseting of options.
1497
1498    * Better support for HPUX.
1499
1500
1501Noteworthy changes in version 0.9.7
1502-----------------------------------
1503
1504    * Add some work arounds for a bugs in pgp 2 which led to bad signatures
1505      when used with canonical texts in some cases.
1506
1507    * Enhanced some status outputs.
1508
1509Noteworthy changes in version 0.9.6
1510-----------------------------------
1511
1512    * Twofish is now statically linked by default. The experimental 128 bit
1513      version is now disabled.	Full support will be available as soon as
1514      the OpenPGP WG has decided on an interpretation of rfc2440.
1515
1516    * Dropped support for the ancient Blowfish160 which is not OpenPGP.
1517
1518    * Merged gpgm and gpg into one binary.
1519
1520    * Add "revsig" and "revkey" commands to the edit menu.  It is now
1521      possible to revoke signature and subkeys.
1522
1523
1524Noteworthy changes in version 0.9.5
1525-----------------------------------
1526
1527    * New command "lsign" in the keyedit menu to create non-exportable
1528      signatures.  Removed --trusted-keys option.
1529
1530    * A bunch of changes to the key validation code.
1531
1532    * --list-trust-path now has an optional --with-colons format.
1533
1534    * New command --recv-keys to import keys from an keyserver.
1535
1536
1537Noteworthy changes in version 0.9.4
1538-----------------------------------
1539
1540    * New configure option --enable-static-rnd=[egd|linux|unix|none]
1541      to select a random gathering module for static linking.
1542
1543    * The original text is now verbatim copied to a cleartext signed message.
1544
1545    * Bugfixes but there are still a couple of bugs.
1546
1547
1548Noteworthy changes in version 0.9.3
1549-----------------------------------
1550
1551    * Changed the internal design of getkey which now allows a
1552      efficient lookup of multiple keys and add a word match mode.
1553
1554    * New options --[no-]encrypt-to.
1555
1556    * Some changes to the configure stuff.  Switched to automake 1.4.
1557      Removed intl/ from CVS, autogen.sh now uses gettextize.
1558
1559    * Preferences now include Twofish. Removed preference to Blowfish with
1560      a special hack to suppress the "not listed in preferences" warning;
1561      this is to allow us to switch completely to Twofish in the near future.
1562
1563    * Changed the locking stuff.
1564
1565    * Print all user ids of a good signature.
1566
1567
1568Noteworthy changes in version 0.9.2
1569-----------------------------------
1570
1571    * add some additional time warp checks.
1572
1573    * Option --keyserver and command --send-keys to utilize HKP servers.
1574
1575    * Upgraded to zlib 1.1.3 and fixed an inflate bug
1576
1577    * More cleanup on the cleartext signatures.
1578
1579
1580Noteworthy changes in version 0.9.1
1581-----------------------------------
1582
1583    * Polish language support.
1584
1585    * When querying the passphrase, the key ID of the primary key is
1586      displayed along with the one of the used secondary key.
1587
1588    * Fixed a bug occurring when decrypting pgp 5 encrypted messages,
1589      fixed an infinite loop bug in the 3DES code and in the code
1590      which looks for trusted signatures.
1591
1592    * Fixed a bug in the mpi library which caused signatures not to
1593      compare okay.
1594
1595    * Rewrote the handling of cleartext signatures; the code is now
1596      better maintainable (I hope so).
1597
1598    * New status output VALIDSIG only for valid signatures together
1599      with the fingerprint of the signer's key.
1600
1601
1602Noteworthy changes in version 0.9.0
1603-----------------------------------
1604
1605    * --export does now only exports rfc2440 compatible keys; the
1606      old behaviour is available with --export-all.
1607      Generation of v3 ElGamal (sign and encrypt) keys is not longer
1608      supported.
1609
1610    * Fixed the uncompress bug.
1611
1612    * Rewrote the rndunix module. There are two environment variables
1613      used for debugging now: GNUPG_RNDUNIX_DBG give the file to write
1614      debugging information (use "-" for stdout) and if GNUPG_RNDUNIX_DBGALL
1615      is set, all programs which are only tried are also printed.
1616
1617    * New option --escape-from-lines to "dash-escape" "From " lines to
1618      prevent mailers to change them to ">From ".  This is not enabled by
1619      default because it is not in compliance with rfc2440 - however, you
1620      should turn it on.
1621
1622
1623Noteworthy changes in version 0.4.5
1624-----------------------------------
1625
1626    * The keyrings and the trustdb is now locked, so that
1627      other GnuPG processes won't damage these files.  You
1628      may want to put the option --lock-once into your options file.
1629
1630    * The latest self-signatures are now used; this enables --import
1631      to see updated preferences etc.
1632
1633    * Import of subkeys should now work.
1634
1635    * Random gathering modules may now be loaded as extensions. Add
1636      such a module for most Unices but it is very experimental!
1637
1638    * Brazilian language support.
1639
1640
1641Noteworthy changes in version 0.4.4
1642-----------------------------------
1643
1644    * Fixed the way the key expiration time is stored. If you have
1645      an expiration time on your key you should fix it with --edit-key
1646      and the command "expire".  I apologize for this inconvenience.
1647
1648    * Add option --charset to support "koi8-r" encoding of user ids.
1649      (Not yet tested).
1650
1651    * Preferences should now work again. You should run
1652      "gpgm --check-trustdb \*" to rebuild all preferences.
1653
1654    * Checking of certificates should now work but this needs a lot
1655      of testing.  Key validation values are now cached in the
1656      trustdb; they should be recalculated as needed, but you may
1657      use --check-trustdb or --update-trustdb to do this.
1658
1659    * Spanish translation by Urko Lusa.
1660
1661    * Patch files are from now on signed.  See the man page
1662      for the new option --not-dash-escaped.
1663
1664    * New syntax: --edit-key <userID> [<commands>]
1665      If you run it without --batch the commands are executed and then
1666      you are put into normal mode unless you use "quit" or "save" as
1667      one of the commands.  When in batch mode, the program quits after
1668      the last command, so you have to use "save" if you did some changes.
1669      It does not yet work completely, but may be used to list so the
1670      keys etc.
1671
1672
1673Noteworthy changes in version 0.4.3
1674-----------------------------------
1675
1676    * Fixed the gettext configure bug.
1677
1678    * Kludge for RSA keys: keyid and length of a RSA key are
1679      correctly reported, but you get an error if you try to use
1680      this key (If you do not have the non-US version).
1681
1682    * Experimental support for keyrings stored in a GDBM database.
1683      This is *much* faster than a standard keyring.  You will notice
1684      that the import gets slower with time; the reason is that all
1685      new keys are used to verify signatures of previous inserted
1686      keys.  Use "--keyring gnupg-gdbm:<name-of-gdbm-file>".  This is
1687      not (yet) supported for secret keys.
1688
1689    * A Russian language file in the distribution (alternatives are in
1690      the contrib directory of the FTP servers)
1691
1692    * commandline option processing now works as expected for GNU programs
1693      with the exception that you can't mix options and normal arguments.
1694
1695    * Now --list-key lists all matching keys.  This is needed in some
1696      other places too.
1697
1698
1699Noteworthy changes in version 0.4.2
1700-----------------------------------
1701
1702    * This is only a snapshot: There are still a few bugs.
1703
1704    * Fixed this huge memory leak.
1705
1706    * Redesigned the trust database:  You should run "gpgm --check-trustdb".
1707      New command --update-trustdb, which adds new key from the public
1708      keyring into your trustdb
1709
1710    * Fixed a bug in the armor code, leading to invalid packet errors.
1711      (a workaround for this was to use --no-armor).  The shorten line
1712      length (64 instead of 72) fixes a problem with pgp5 and keyservers.
1713
1714    * comment packets are not anymore generated. "--export" filters
1715      them out.  One Exception:  The comment packets in a secret keyring
1716      are still used because they carry the factorization of the public
1717      prime product.
1718
1719    * --import now only looks for KEYBLOCK headers, so you can now simply
1720      remove the "- " in front of such a header if someone accidently signed
1721      such a message or the keyblock is part of a cleartext signed message.
1722
1723    * --with-colons now lists the key expiration time and not anymore
1724      the valid period.
1725
1726    * Some keyblocks created with old releases have a wrong sequence
1727      of packets, so that the keyservers don't accept these keys.
1728      Simply using "--edit-key" fixes the problem.
1729
1730    * New option --force-v3-sigs to generate signed messages which are
1731      compatible to PGP 5.
1732
1733    * Add some code to support DLD (for non ELF systems) - but this is
1734      not tested because my BSD box is currently broken.
1735
1736    * New command "expire" in the edit-key menu.
1737
1738
1739
1740Noteworthy changes in version 0.4.1
1741-----------------------------------
1742    * A secondary key is used when the primary key is specified but cannot
1743      be used for the operation (if it is a sign-only key).
1744
1745    * GNUPG can now handle concatenated armored messages:  There is still a
1746      bug if different kinds of messages are mixed.
1747
1748    * Iterated+Salted passphrases now work.  If want to be sure that PGP5
1749      is able to handle them you may want to use the options
1750	"--s2k-mode 3 --s2k-cipher-algo cast5 --s2k-digest-algo sha1"
1751      when changing a passphrase.
1752
1753    * doc/OpenPGP talks about OpenPGP compliance, doc/HACKING gives
1754      a few hints about the internal structure.
1755
1756    * Checked gnupg against the August 1998 draft (07) and I believe
1757      it is in compliance with this document (except for one point).
1758
1759    * Fixed some bugs in the import merging code and rewrote some
1760      code for the trustdb.
1761
1762
1763Noteworthy changes in version 0.4.0
1764-----------------------------------
1765    * Triple DES is now supported.  Michael Roth did this piece of
1766      needed work.  We have now all the coded needed to be OpenPGP
1767      compliant.
1768
1769    * Added a simple rpm spec file (see INSTALL).
1770
1771    * detached and armored signatures are now using "PGP SIGNATURE",
1772      except when --rfc1991 is used.
1773
1774    * All times which are not in the yyyy-mm-dd format are now printed
1775      in local time.
1776
1777
1778Noteworthy changes in version 0.3.5
1779-----------------------------------
1780    * New option --throw-keyid to create anonymous enciphered messages.
1781      If gpg detects such a message it tires all available secret keys
1782      in turn so decode it.  This is a gnupg extension and not in OpenPGP
1783      but it has been discussed there and afaik some products use this
1784      scheme too (Suggested by Nimrod Zimmerman).
1785
1786    * Fixed a bug with 5 byte length headers.
1787
1788    * --delete-[secret-]key is now also available in gpgm.
1789
1790    * cleartext signatures are not anymore converted to LF only.
1791
1792    * Fixed a trustdb problem.	Run "gpgm --check-trustdb" to fix old
1793      trust dbs.
1794
1795    * Building in another directory should now work.
1796
1797    * Weak key detection mechanism (Niklas Hernaeus).
1798
1799
1800Noteworthy changes in version 0.3.4
1801-----------------------------------
1802    * New options --comment and --set-filename; see g10/OPTIONS
1803
1804    * yes/no, y/n localized.
1805
1806    * Fixed some bugs.
1807
1808Noteworthy changes in version 0.3.3
1809-----------------------------------
1810    * IMPORTANT: I found yet another bug in the way the secret keys
1811      are encrypted - I did it the way pgp 2.x did it, but OpenPGP
1812      and pgp 5.x specify another (in some aspects simpler) method.
1813      To convert your secret keys you have to do this:
1814	1. Build the new release but don't install it and keep
1815	   a copy of the old program.
1816	2. Disable the network, make sure that you are the only
1817	   user, be sure that there are no Trojan horses etc ....
1818	3. Use your old gpg (version 0.3.[12]) and set the
1819	   passphrases of ALL your secret keys to empty!
1820	   (gpg --change-passphrase your-user-id).
1821	4. Save your ownertrusts (see the next point)
1822	5. rm ~/.gnupg/trustdb.gpg
1823	6. install the new version of gpg (0.3.3)
1824	7. For every secret key call "gpg --edit-key your-user-id",
1825	   enter "passwd" at the prompt, follow the instructions and
1826	   change your password back, enter "save" to store it.
1827	8. Restore the ownertrust (see next point).
1828
1829    * The format of the trust database has changed; you must delete
1830      the old one, so gnupg can create a new one.
1831      IMPORTANT: Use version 0.3.[12] to save your assigned ownertrusts
1832      ("gpgm --list-ownertrust >saved-trust"); then build this new version
1833      and restore the ownertrust with this new version
1834      ("gpgm --import-ownertrust saved-trust").  Please note that
1835      --list-ownertrust has been renamed to --export-ownertrust in this
1836      release and it does now only export defined ownertrusts.
1837
1838    * The command --edit-key now provides a commandline driven menu
1839      which can be used for various tasks.  --sign-key is only an
1840      an alias to --edit-key and maybe removed in future: use the
1841      command "sign" of this new menu - you can select which user ids
1842      you want to sign.
1843
1844    * Alternate user ids can now be created an signed.
1845
1846    * Owner trust values can now be changed with --edit-key (trust)
1847
1848    * GNUPG can now run as a coprocess; this enables sophisticated
1849      frontends.  tools/shmtest.c is a simple sample implementation.
1850      This needs some more work: all tty_xxx() are to be replaced
1851      by cpr_xxx() and some changes in the display logics is needed.
1852
1853    * Removed options --gen-prime and --gen-random.
1854
1855    * Removed option --add-key; use --edit-key instead.
1856
1857    * Removed option --change-passphrase; use --edit-key instead.
1858
1859    * Signatures are now checked even if the output file could not
1860      be created. Command "--verify" tries to find the detached data.
1861
1862    * gpg now disables core dumps.
1863
1864    * compress and symmetric cipher preferences are now used.
1865      Because there is no 3DES yet, this is replaced by Blowfish.
1866
1867    * We have added the Twofish as an experimental cipher algorithm.
1868      Many thanks to Matthew Skala for doing this work.
1869      Twofish is the AES submission from Schneier et al.; see
1870      "www.counterpane.com/twofish.html" for more information.
1871
1872    * Started with a help system: If you enter a question mark at some
1873      prompt; you should get a specific help for this prompt.
1874
1875    * There is no more backup copy of the secret keyring.
1876
1877    * A lot of new bugs. I think this release is not as stable as
1878      the previous one.
1879
1880
1881Noteworthy changes in version 0.3.2
1882-----------------------------------
1883    * Fixed some bugs when using --textmode (-seat)
1884
1885    * Now displays the trust status of a positive verified message.
1886
1887    * Keyrings are now scanned in the sequence they are added with
1888      --[secret-]keyring.  Note that the default keyring is implicitly
1889      added as the very first one unless --no-default-keyring is used.
1890
1891    * Fixed setuid and dlopen bug.
1892
1893Noteworthy changes in version 0.3.1
1894-----------------------------------
1895    * Partial headers are now written in the OpenPGP format if
1896      a key in a v4 packet is used.
1897
1898    * Removed some unused options, removed the gnupg.sig stuff.
1899
1900    * Key lookup by name now returns a key which can be used for
1901      the desired action.
1902
1903    * New options --list-ownertrust (gpgm) to make a backup copy
1904      of the ownertrust values you assigned.
1905
1906    * clear signature headers are now in compliance with OpenPGP.
1907
1908Noteworthy changes in version 0.3.0
1909-----------------------------------
1910
1911    * New option --emulate-checksum-bug.  If your passphrase does not
1912      work anymore, use this option and --change-passphrase to rewrite
1913      your passphrase.
1914
1915    * More complete v4 key support: Preferences and expiration time
1916      is set into the self signature.
1917
1918    * Key generation defaults to DSA/ElGamal keys, so that new keys are
1919      interoperable with pgp5
1920
1921    * DSA key generation is faster and key generation does not anymore
1922      remove entropy from the random generator (the primes are public
1923      parameters, so there is really no need for a cryptographic secure
1924      prime number generator which we had used).
1925
1926    * A complete new structure for representing the key parameters.
1927
1928    * Removed most public key knowledge into the cipher library.
1929
1930    * Support for dynamic loading of new algorithms.
1931
1932    * Moved tiger to an extension module.
1933
1934
1935Noteworthy changes in version 0.2.19
1936------------------------------------
1937
1938    * Replaced /dev/urandom in checks with new tool mk-tdata.
1939
1940    * Some assembler file cleanups; some more functions for the Alpha.
1941
1942    * Tiger has now the OpenPGP assigned number 6.  Because the OID has
1943      changed, old signatures using this algorithm can't be verified.
1944
1945    * gnupg now encrypts the compressed packed and not any longer in the
1946      reverse order; anyway it can decrypt both versions. Thanks to Tom
1947      for telling me this (not security related) bug.
1948
1949    * --add-key works and you are now able to generate subkeys.
1950
1951    * It is now possible to generate ElGamal keys in v4 packets to create
1952      valid OpenPGP keys.
1953
1954    * Some new features for better integration into MUAs.
1955
1956
1957Noteworthy changes in version 0.2.18
1958------------------------------------
1959
1960    * Splitted cipher/random.c, add new option "--disable-dev-random"
1961      to configure to support the development of a random source for
1962      other systems. Prepared sourcefiles rand-unix.c, rand-w32.c
1963      and rand-dummy.c (which is used to allow compilation on systems
1964      without a random source).
1965
1966    * Fixed a small bug in the key generation (it was possible that 48 bits
1967      of a key were not taken from the random pool)
1968
1969    * Add key generation for DSA and v4 signatures.
1970
1971    * Add a function trap_unaligned(), so that a SIGBUS is issued on
1972      Alphas and not the slow emulation code is used. And success: rmd160
1973      raised a SIGBUS.
1974
1975    * Enhanced the formatting facility of argparse and changed the use of
1976      \r,\v to @ because gettext does not like it.
1977
1978    * New option "--compress-algo 1" to allow the creation of compressed
1979      messages which are readable by PGP and "--print-md" (gpgm) to make
1980      speed measurement easier.
1981
1982
1983Noteworthy changes in version 0.2.17
1984------------------------------------
1985
1986    * Comment packets are now of private type 61.
1987
1988    * Passphrase code still used a 160 bit blowfish key, added a
1989      silly workaround. Please change your passphrase again - sorry.
1990
1991    * Conventional encryption now uses a type 3 packet to describe the
1992      used algorithms.
1993
1994    * The new algorithm number for Blowfish is 20, 16 is still used for
1995      encryption only; for signing it is only used when it is in a v3 packet,
1996      so that GNUPG keys are still valid.
1997
1998
1999Noteworthy changes in version 0.2.16
2000------------------------------------
2001
2002    * Add experimental support for the TIGER/192 message digest algorithm.
2003      (But there is only a dummy ASN OID).
2004
2005    * Standard cipher is now Blowfish with 128 bit key in OpenPGP's CFB
2006      mode. I renamed the old cipher to Blowfish160. Because the OpenPGP
2007      group refused to assign me a number for Blowfish160, I have to
2008      drop support for this in the future. You should use
2009      "--change-passphrase" to recode your current passphrase with 128
2010      bit Blowfish.
2011
2012
2013Noteworthy changes in version 0.2.15
2014------------------------------------
2015
2016    * Fixed a bug with the old checksum calculation for secret keys.
2017      If you run the program without --batch, a warning does inform
2018      you if your secret key needs to be converted; simply use
2019      --change-passphrase to recalculate the checksum. Please do this
2020      soon, as the compatible mode will be removed sometime in the future.
2021
2022    * CAST5 works (using the PGP's special CFB mode).
2023
2024    * Again somewhat more PGP 5 compatible.
2025
2026    * Some new test cases
2027
2028Noteworthy changes in version 0.2.14
2029------------------------------------
2030
2031    * Changed the internal handling of keyrings.
2032
2033    * Add support to list PGP 5 keyrings with subkeys
2034
2035    * Timestamps of signatures are now verified.
2036
2037    * A expiration time can now be specified during key generation.
2038
2039    * Some speedups for Blowfish and SHA-1, rewrote SHA-1 transform.
2040      Reduced the amount of random bytes needed for key generation in
2041      some cases.
2042
2043
2044Noteworthy changes in version 0.2.13
2045------------------------------------
2046
2047    * Verify of DSA signatures works.
2048
2049    * Re-implemented the slower random number generator.
2050
2051
2052Noteworthy changes in version 0.2.12
2053------------------------------------
2054
2055    * --delete-key checks that there is no secret key. The new
2056      option --delete-secret-key maybe used to delete a secret key.
2057
2058    * "-kv" now works as expected. Options "--list-{keys,sigs]"
2059      and "--check-sigs" are now working.
2060
2061    * New options "--verify" and "--decrypt" to better support integration
2062      into MUAs (partly done for Mutt).
2063
2064    * New option "--with-colons" to make parsing of key lists easier.
2065
2066Noteworthy changes in version 0.2.11
2067------------------------------------
2068
2069    * GPG now asks for a recipient's name if option "-r" is not used.
2070
2071    * If there is no good trust path, the program asks whether to use
2072      the public keys anyway.
2073
2074    * "--delete-key" works for public keys. What semantics shall I use
2075      when there is a secret key too? Delete the secret key or leave him
2076      and auto-regenerate the public key, next time the secret key is used?
2077
2078Noteworthy changes in version 0.2.10
2079------------------------------------
2080
2081    * Code for the alpha is much faster (about 20 times); the data
2082      was misaligned and the kernel traps this, so nearly all time
2083      was used by system to trap the misalignments and to write
2084      syslog messages. Shame on me and thanks to Ralph for
2085      pointing me at this while drinking some beer yesterday.
2086
2087    * Changed some configure options and add an option
2088      --disable-m-guard to remove the memory checking code
2089      and to compile everything with optimization on.
2090
2091    * New environment variable GNUPGHOME, which can be used to set
2092      another homedir than ~/.gnupg.  Changed default homedir for
2093      Windoze version to c:/gnupg.
2094
2095    * Fixed detached signatures; detached PGP signatures caused a SEGV.
2096
2097    * The Windoze version works (as usual w/o a strong RNG).
2098
2099
2100Noteworthy changes in version 0.2.9
2101-----------------------------------
2102
2103    * Fixed FreeBSD bug.
2104
2105    * Added a simple man page.
2106
2107    * Switched to automake1.2f and a newer gettext.
2108
2109Noteworthy changes in version 0.2.8
2110-----------------------------------
2111
2112    * Changed the name to GNUPG, the binaries are called gpg and gpgm.
2113      You must rename rename the directory "~/.g10" to ~/.gnupg/, rename
2114      {pub,sec}ring.g10 to {pub,sec}ring.gpg, trustdb.g10 to trustdb.gpg
2115      and g10.sig to gnupg.sig.
2116
2117    * New or changed passphrases are now salted.
2118
2119
2120Noteworthy changes in version 0.2.7
2121-----------------------------------
2122
2123    * New command "gen-revoke" to create a key revocation certificate.
2124
2125    * New option "homedir" to set the homedir (which defaults to "~/.g10").
2126      This directory is created if it does not exists (only the last
2127      part of the name and not the complete hierarchy)
2128
2129    * Command "import" works. (Try: "finger gcrypt@ftp.guug.de|g10 --import")
2130
2131    * New commands "dearmor/enarmor" for g10maint.  These are mainly
2132      used for internal test purposes.
2133
2134    * Option --version now conforming to the GNU standards and lists
2135      the available ciphers, message digests and public key algorithms.
2136
2137    * Assembler code for m68k (not tested).
2138
2139    * "make check" works.
2140
2141Noteworthy changes in version 0.2.6
2142-----------------------------------
2143
2144    * Option "--export" works.
2145
2146
2147Noteworthy changes in version 0.2.5
2148-----------------------------------
2149
2150    * Added zlib for systems which don't have it.
2151      Use "./configure --with-zlib" to link with the static version.
2152
2153    * Generalized some more functions and rewrote the encoding of
2154      message digests into MPIs.
2155
2156    * Enhanced the checkit script
2157
2158
2159Noteworthy changes in version 0.2.4
2160-----------------------------------
2161
2162    * nearly doubled the speed of the ElGamal signature verification.
2163
2164    * backup copies of keyrings are created.
2165
2166    * assembler stuff for Pentium; gives about 15% better performance.
2167
2168    * fixed a lot of bugs.
2169
2170
2171Noteworthy changes in version 0.2.3
2172-----------------------------------
2173
2174    * Found a bug in the calculation of ELG fingerprints. This is now
2175      fixed, but all existing fingerprints and keyids for ELG keys
2176      are not any more valid.
2177
2178    * armor should now work; including clear signed text.
2179
2180    * moved some options to the new program g10maint
2181
2182    * It's now 64 bit clean and runs fine on an alpha--linux.
2183
2184    * Key generation is much faster now.  I fixed this by using not
2185      so strong random number for the primes (this was a bug because the
2186      ElGamal primes are public parameters and it does not make sense
2187      to generate them from strong random).  The real secret is the x value
2188      which is still generated from strong (okay: /dev/random) random bits.
2189
2190    * added option "--status-fd": see g10/OPTIONS
2191
2192    * We have secure memory on systems which support mlock().
2193      It is not complete yet, because we do not have signal handler
2194      which does a cleanup in very case.
2195      We should also check the ulimit for the user in the case
2196      that the admin does not have set a limit on locked pages.
2197
2198    * started with internationalization support.
2199
2200    * The logic to handle the web of trust is now implemented. It is
2201      has some bugs; but I'm going to change the algorithm anyway.
2202      It works by calculating the trustlevel on the fly.  It may ask
2203      you to provide trust parameters if the calculated trust probability
2204      is too low.  I will write a paper which discusses this new approach.
2205
2206    * a couple of changes to the configure script.
2207
2208    * New option "--quick-random" which uses a much quicker random
2209      number generator.  Keys generated while this option is in effect
2210      are flags with "INSECURE!" in the user-id.  This is a development
2211      only option.
2212
2213    * Read support for new version packets (OpenPGP).
2214
2215    * Comment packets are now of correct OpenPGP type 16. Old comment
2216      packets written by G10 are detected because they always start with
2217      a hash which is an invalid version byte.
2218
2219    * The string "(INSECURE!)" is appended to a new user-id if this
2220      is generated on a system without a good random number generator.
