gnupg/NEWS

    * Fixed the gettext configure bug.

    * Kludge for RSA keys: keyid and length of a RSA key are
      correctly reported, but you get an error if you try to use
      this key (If you do not have the non-US version).

    * Experimental support for keyrings stored in a GDBM database.
      This is *much* faster than a standard keyring.  You will notice
      that the import gets slower with time; the reason is that all
      new keys are used to verify signatures of previous inserted
      keys.  Use "--keyring gnupg-gdbm:<name-of-gdbm-file>".  This is
      not (yet) supported for secret keys.

    * A Russian language file in the distribution (alternatives are in
      the contrib directory of the FTP servers)



Noteworthy changes in version 0.4.2
-----------------------------------

    * This is only a snapshot: There are still a few bugs.

    * Fixed this huge memory leak.

    * Redesigned the trust database:  You should run "gpgm --check-trustdb".
      New command --update-trustdb, which adds new key from the public
      keyring into your trustdb

    * Fixed a bug in the armor code, leading to invalid packet errors.
      (a workaround for this was to use --no-armor).  The shorten line
      length (64 instead of 72) fixes a problem with pgp5 and keyservers.

    * comment packets are not anymore generated. "--export" filters
      them out.  One Exception:  The comment packets in a secret keyring
      are still used because they carry the factorization of the public
      prime product.

    * --import now only looks for KEYBLOCK headers, so you can now simply
      remove the "- " in front of such a header if someone accdently signed
      such a message or the keyblock is part of a cleartext signed message.

    * --with-colons now lists the key expiration time and not anymore
      the valid period.

    * Some keyblocks created with old releases have a wrong sequence
      of packets, so that the keyservers don't accept these keys.
      Simply using "--edit-key" fixes the problem.

    * New option --force-v3-sigs to generate signed messages which are
      compatible to PGP 5.

    * Add some code to support DLD (for non ELF systems) - but this is
      not tested because my BSD box is currently broken.

    * New command "expire" in the edit-key menu.



Noteworthy changes in version 0.4.1
-----------------------------------
    * A secondary key is used when the primary key is specified but cannot
      be used for the operation (if it is a sign-only key).

    * GNUPG can now handle concatenated armored messages:  There is still a
      bug if different kinds of messages are mixed.

    * Iterated+Salted passphrases now work.  If want to be sure that PGP5
      is able to handle them you may want to use the options
	"--s2k-mode 3 --s2k-cipher-algo cast5 --s2k-digest-algo sha1"
      when changing a passphrase.

    * doc/OpenPGP talks about OpenPGP compliance, doc/HACKING gives
      a few hints about the internal structure.

    * Checked gnupg against the August 1998 draft (07) and I believe
      it is in compliance with this document (except for one point).

    * Fixed some bugs in the import merging code and rewrote some
      code for the trustdb.


Noteworthy changes in version 0.4.0
-----------------------------------
    * Triple DES is now supported.  Michael Roth did this piece of
      needed work.  We have now all the coded needed to be OpenPGP
      compliant.

    * Added a simple rpm spec file (see INSTALL).

    * detached and armored signatures are now using "PGP SIGNATURE",
      except when --rfc1991 is used.

    * All times which are not in the yyy-mm-dd format are now printed
      in local time.


Noteworthy changes in version 0.3.5
-----------------------------------
    * New option --throw-keyid to create anonymous enciphered messages.
      If gpg detects such a message it tires all available secret keys
      in turn so decode it.  This is a gnupg extension and not in OpenPGP
      but it has been discussed there and afaik some products use this
      scheme too (Suggested by Nimrod Zimmerman).

    * Fixed a bug with 5 byte length headers.

    * --delete-[secret-]key is now also availabe in gpgm.

    * cleartext signatures are not anymore converted to LF only.

    * Fixed a trustdb problem.	Run "gpgm --check-trustdb" to fix old
      trust dbs.

    * Building in another directory should now work.

    * Weak key detection mechanism (Niklas Hernaeus).


Noteworthy changes in version 0.3.4
-----------------------------------
    * New options --comment and --set-filename; see g10/OPTIONS

    * yes/no, y/n localized.

    * Fixed some bugs.

Noteworthy changes in version 0.3.3
-----------------------------------
    * IMPORTANT: I found yet another bug in the way the secret keys
      are encrypted - I did it the way pgp 2.x did it, but OpenPGP
      and pgp 5.x specifiy another (in some aspects simpler) method.
      To convert your secret keys you have to do this:
	1. Build the new release but don't install it and keep
	   a copy of the old program.
	2. Disable the network, make sure that you are the only
	   user, be sure that there are no trojan horses etc ....
	3. Use your old gpg (version 0.3.[12]) and set the
	   passphrases of ALL your secret keys to empty!
	   (gpg --change-passphrase your-user-id).
	4. Save your ownertrusts (see the next point)
	5. rm ~/.gnupg/trustd.gpg
	6. install the new version of gpg (0.3.3)
	7. For every secret key call "gpg --edit-key your-user-id",
	   enter "passwd" at the prompt, follow the instructions and
	   change your passward back, enter "save" to store it.
	8. Restore the ownertrust (see next point).

    * The format of the trust database has changed; you must delete
      the old one, so gnupg can create a new one.
      IMPORTANT: Use version 0.3.[12] to save your assigned ownertrusts
      ("gpgm --list-ownertrust >saved-trust"); then build this new version
      and restore the ownertrust with this new version
      ("gpgm --import-ownertrust saved-trust").  Please note that
      --list-ownertrust has been renamed to --export-ownertrust in this
      release and it does now only export defined ownertrusts.

    * The command --edit-key now provides a commandline driven menu
      which can be used vor vaious tasks.  --sign-key is only an
      an alias to --edit-key and maybe removed in future: use the
      command "sign" of this new menu - you can select which user ids
      you want to sign.

    * Alternate user ids can now be created an signed.

    * Owner trust values can now be changed with --edit-key (trust)

    * GNUPG can now run as a coprocess; this enables sophisticated
      frontends.  tools/shmtest.c is a simple sample implemenation.
      This needs some more work: all tty_xxx() are to be replaced
      by cpr_xxx() and some changes in the display logics is needed.

    * Removed options --gen-prime and --gen-random.

    * Removed option --add-key; use --edit-key instead.

    * Removed option --change-passphrase; use --edit-key instead.

    * Signatures are now checked even if the output file could not
      be created. Command "--verify" tries to find the detached data.

    * gpg now disables core dumps.

    * compress and symmetric cipher preferences are now used.
      Because there is no 3DES yet, this is replaced by Blowfish.

    * We have added the Twofish as an experimental cipher algorithm.
      Many thanks to Matthew Skala for doing this work.
      Twofish is the AES submission from Schneier et al.; see
      "www.counterpane.com/twofish.html" for more information.

    * Started with a help system: If you enter a question mark at some
      prompt; you should get a specific help for this prompt.

    * There is no more backup copy of the secret keyring.

    * A lot of new bugs. I think this release is not as stable as
      the previous one.


Noteworthy changes in version 0.3.2
-----------------------------------
    * Fixed some bugs when using --textmode (-seat)

    * Now displays the trust status of a positive verified message.

    * Keyrings are now scanned in the sequence they are added with
      --[secret-]keyring.  Note that the default keyring is implictly
      added as the very first one unless --no-default-keyring is used.

    * Fixed setuid and dlopen bug.

Noteworthy changes in version 0.3.1
-----------------------------------
    * Partial headers are now written in the OpenPGP format if
      a key in a v4 packet is used.

    * Removed some unused options, removed the gnupg.sig stuff.

    * Key lookup by name now returns a key which can be used for
      the desired action.

    * New options --list-ownertrust (gpgm) to make a backup copy
      of the ownertrust values you assigned.

    * clear signature headers are now in compliance with OpenPGP.

Noteworthy changes in version 0.3.0
-----------------------------------

    * New option --emulate-checksum-bug.  If your passphrase does not
      work anymore, use this option and --change-passphrase to rewrite
      your passphrase.

    * More complete v4 key support: Preferences and expiration time
      is set into the self signature.

    * Key generation defaults to DSA/ElGamal keys, so that new keys are
      interoperable with pgp5

    * DSA key generation is faster and key generation does not anymore
      remove entropy from the random generator (the primes are public
      parameters, so there is really no need for a cryptographic secure
      prime number generator which we had used).

    * A complete new structure for representing the key parameters.

    * Removed most public key knowledge into the cipher libray.

    * Support for dynamic loading of new algorithms.

    * Moved tiger to an extension module.


Noteworthy changes in version 0.2.19
------------------------------------

    * Replaced /dev/urandom in checks with new tool mk-tdata.

    * Some assembler file cleanups; some more functions for the Alpha.

    * Tiger has now the OpenPGP assigned number 6.  Because the OID has
      changed, old signatures using this algorithm can't be verified.

    * gnupg now encrypts the compressed packed and not any longer in the
      reverse order; anyway it can decrypt both versions. Thanks to Tom
      for telling me this (not security related) bug.

    * --add-key works and you are now able to generate subkeys.

    * It is now possible to generate ElGamal keys in v4 packets to create
      valid OpenPGP keys.

    * Some new features for better integration into MUAs.


Noteworthy changes in version 0.2.18
------------------------------------

    * Splitted cipher/random.c, add new option "--disable-dev-random"
      to configure to support the development of a random source for
      other systems. Prepared sourcefiles rand-unix.c, rand-w32.c
      and rand-dummy.c (which is used to allow compilation on systems
      without a random source).

    * Fixed a small bug in the key generation (it was possible that 48 bits
      of a key were not taken from the random pool)

    * Add key generation for DSA and v4 signatures.

    * Add a function trap_unaligned(), so that a SIGBUS is issued on
      Alphas and not the slow emulation code is used. And success: rmd160
      raised a SIGBUS.

    * Enhanced the formatting facility of argparse and changed the use of
      \r,\v to @ because gettext does not like it.

    * New option "--compress-algo 1" to allow the creation of compressed
      messages which are readable by PGP and "--print-md" (gpgm) to make
      speed measurement easier.


Noteworthy changes in version 0.2.17
------------------------------------

    * Comment packets are now of private type 61.

    * Passphrase code still used a 160 bit blowfish key, added a
      silly workaround. Please change your passphrase again - sorry.

    * Conventional encryption now uses a type 3 packet to describe the
      used algorithms.

    * The new algorithm number for Blowfish is 20, 16 is still used for
      encryption only; for signing it is only used when it is in a v3 packet,
      so that GNUPG keys are still valid.


Noteworthy changes in version 0.2.16
------------------------------------

    * Add experimental support for the TIGER/192 message diigest algorithm.
      (But there is only a dummy ASN OID).

    * Standard cipher is now Blowfish with 128 bit key in OpenPGP's CFB
      mode. I renamed the old cipher to Blowfish160. Because the OpenPGP
      group refused to assign me a number for Blowfish160, I have to
      drop support for this in the future. You should use
      "--change-passphrase" to recode your current passphrase with 128
      bit Blowfish.


Noteworthy changes in version 0.2.15
------------------------------------

    * Fixed a bug with the old checksum calculation for secret keys.
      If you run the program without --batch, a warning does inform
      you if your secret key needs to be converted; simply use
      --change-passphrase to recalculate the checksum. Please do this
      soon, as the compatible mode will be removed sometime in the future.

    * CAST5 works (using the PGP's special CFB mode).

    * Again somewhat more PGP 5 compatible.

    * Some new test cases

Noteworthy changes in version 0.2.14
------------------------------------

    * Changed the internal handling of keyrings.

    * Add support to list PGP 5 keyrings with supkeys

    * Timestamps of signatures are now verified.

    * A expiration time can now be specified during key generation.

    * Some speedups for Blowfish and SHA-1, rewrote SHA-1 transform.
      Reduced the amount of random bytes needed for key generation in
      some cases.


Noteworthy changes in version 0.2.13
------------------------------------

    * Verify of DSA signatures works.

    * Re-implemented the slower random number generator.


Noteworthy changes in version 0.2.12
------------------------------------

    * --delete-key checks that there is no secret key. The new
      option --delete-secret-key maybe used to delete a secret key.

    * "-kv" now works as expected. Options "--list-{keys,sigs]"
      and "--check-sigs" are now working.

    * New options "--verify" and "--decrypt" to better support integration
      into MUAs (partly done for Mutt).

    * New option "--with-colons" to make parsing of key lists easier.

Noteworthy changes in version 0.2.11
------------------------------------

    * GPG now asks for a recipient's name if option "-r" is not used.

    * If there is no good trust path, the program asks whether to use
      the public keys anyway.

    * "--delete-key" works for public keys. What semantics shall I use
      when there is a secret key too? Delete the secret key or leave him
      and auto-regenerate the public key, netxt time the secret key is used?

Noteworthy changes in version 0.2.10
------------------------------------

    * Code for the alpha is much faster (about 20 times); the data
      was misaligned and the kernel traps this, so nearly all time
      was used by system to trap the misalignments and to write
      syslog messages. Shame on me and thanks to Ralph for
      pointing me at this while drinking some beer yesterday.

    * Changed some configure options and add an option
      --disable-m-guard to remove the memory checking code
      and to compile everthing with optimization on.

    * New environment variable GNUPGHOME, which can be used to set
      another homedir than ~/.gnupg.  Changed default homedir for
      Windoze version to c:/gnupg.

    * Fixed detached signatures; detached PGP signatures caused a SEGV.

    * The Windoze version works (as usual w/o a strong RNG).


Noteworthy changes in version 0.2.9
-----------------------------------

    * Fixed FreeBSD bug.

    * Added a simple man page.

    * Switched to automake1.2f and a newer gettext.

Noteworthy changes in version 0.2.8
-----------------------------------

    * Changed the name to GNUPG, the binaries are called gpg and gpgm.
      You must rename rename the directory "~/.g10" to ~/.gnupg/, rename
      {pub,sec}ring.g10 to {pub,sec}ring.gpg, trustdb.g10 to trustdb.gpg
      and g10.sig to gnupg.sig.

    * New or changed passphrases are now salted.


Noteworthy changes in version 0.2.7
-----------------------------------

    * New command "gen-revoke" to create a key revocation certificate.

    * New option "homedir" to set the homedir (which defaults to "~/.g10").
      This directory is created if it does not exists (only the last
      part of the name and not the complete hierarchy)

    * Command "import" works. (Try: "finger gcrypt@ftp.guug.de|g10 --import")

    * New commands "dearmor/enarmor" for g10maint.  These are mainly
      used for internal test purposes.

    * Option --version now conforming to the GNU standards and lists
      the available ciphers, message digests and public key algorithms.

    * Assembler code for m68k (not tested).

    * "make check" works.

Noteworthy changes in version 0.2.6
-----------------------------------

    * Option "--export" works.


Noteworthy changes in version 0.2.5
-----------------------------------

    * Added zlib for systems which don't have it.
      Use "./configure --with-zlib" to link with the static version.

    * Generalized some more functions and rewrote the encoding of
      message digests into MPIs.

    * Enhanced the checkit script


Noteworthy changes in version 0.2.4
-----------------------------------

    * nearly doubled the speed of the ElGamal signature verification.

    * backup copies of keyrings are created.

    * assembler stuff for Pentium; gives about 15% better perfomance.

    * fixed a lot of bugs.


Noteworthy changes in version 0.2.3
-----------------------------------

    * Found a bug in the calculation of ELG fingerprints. This is now
      fixed, but all existing fingerprints and keyids for ELG keys
      are not any more valid.

    * armor should now work; including clear signed text.

    * moved some options to the new program g10maint

    * It's now 64 bit clean and runs fine on an alpha--linux.

    * Key generation is much faster now.  I fixed this by using not
      so strong random number for the primes (this was a bug because the
      ElGamal primes are public parameters and it does not make sense
      to generate them from strong random).  The real secret is the x value
      which is still generated from strong (okay: /dev/random) random bits.

    * added option "--status-fd": see g10/OPTIONS

    * We have secure memeory on systems which support mlock().
      It is not complete yet, because we do not have signal handler
      which does a cleanup in very case.
      We should also check the ulimit for the user in the case
      that the admin does not have set a limit on locked pages.

    * started with internationalization support.

    * The logic to handle the web of trust is now implemented. It is
      has some bugs; but I'm going to change the algorithm anyway.
      It works by calculating the trustlevel on the fly.  It may ask
      you to provide trust parameters if the calculated trust probability
      is too low.  I will write a paper which discusses this new approach.

    * a couple of changes to the configure script.

    * New option "--quick-random" which uses a much quicker random
      number generator.  Keys generated while this option is in effect
      are flags with "INSECURE!" in the user-id.  This is a development
      only option.

    * Read support for new version packets (OpenPGP).

    * Comment packets are now of correct OpenPGP type 16. Old comment
      packets written by G10 are detected because they always start with
      a hash which is an invalid version byte.

    * The string "(INSECURE!)" is appended to a new user-id if this
      is generated on a system without a good random number generator.
