1 This is NOT a released version!
2 -------------------------------
4 * Fixed the way the key expiration time is stored. If you have
5 an expiration time on your key you should fix it with --edit-key
6 and the command "expire". I apologize for this inconvenience.
8 * Add option --charset to support "koi8-r" encoding of user ids.
11 * Preferences should now work again. You should run
12 "gpgm --check-trustdb \*" to rebuild all preferences.
14 * Checking of certificates should now work but this needs a lot
15 of testing. Key validation values are now cached in the
16 trustdb; they should be recalculated as needed, but you may
17 use --check-trustdb or --update-trustdb to do this.
19 * Spanish translation by Urko Lusa.
21 * Patch files are from now on signed. See the man page
22 for the new option --not-dash-escaped.
24 * New syntax: --edit-key <userID> [<commands>]
25 If you run it without --batch the commands are executed and then
26 you are put into normal mode unless you use "quit" or "save" as
27 one of the commands. When in batch mode, the program quits after
28 the last command, so you have to use "save" if you did some changes.
29 It does not yet work completey, but may be used to list so the
33 Noteworthy changes in version 0.4.3
34 -----------------------------------
36 * Fixed the gettext configure bug.
38 * Kludge for RSA keys: keyid and length of a RSA key are
39 correctly reported, but you get an error if you try to use
40 this key (If you do not have the non-US version).
42 * Experimental support for keyrings stored in a GDBM database.
43 This is *much* faster than a standard keyring. You will notice
44 that the import gets slower with time; the reason is that all
45 new keys are used to verify signatures of previous inserted
46 keys. Use "--keyring gnupg-gdbm:<name-of-gdbm-file>". This is
47 not (yet) supported for secret keys.
49 * A Russian language file in the distribution (alternatives are in
50 the contrib directory of the FTP servers)
52 * commandline option processing now works as expected for GNU programs
53 with the execption that you can't mix options and normal arguments.
55 * Now --list-key lists all matching keys. This is needed in some
59 Noteworthy changes in version 0.4.2
60 -----------------------------------
62 * This is only a snapshot: There are still a few bugs.
64 * Fixed this huge memory leak.
66 * Redesigned the trust database: You should run "gpgm --check-trustdb".
67 New command --update-trustdb, which adds new key from the public
68 keyring into your trustdb
70 * Fixed a bug in the armor code, leading to invalid packet errors.
71 (a workaround for this was to use --no-armor). The shorten line
72 length (64 instead of 72) fixes a problem with pgp5 and keyservers.
74 * comment packets are not anymore generated. "--export" filters
75 them out. One Exception: The comment packets in a secret keyring
76 are still used because they carry the factorization of the public
79 * --import now only looks for KEYBLOCK headers, so you can now simply
80 remove the "- " in front of such a header if someone accdently signed
81 such a message or the keyblock is part of a cleartext signed message.
83 * --with-colons now lists the key expiration time and not anymore
86 * Some keyblocks created with old releases have a wrong sequence
87 of packets, so that the keyservers don't accept these keys.
88 Simply using "--edit-key" fixes the problem.
90 * New option --force-v3-sigs to generate signed messages which are
93 * Add some code to support DLD (for non ELF systems) - but this is
94 not tested because my BSD box is currently broken.
96 * New command "expire" in the edit-key menu.
100 Noteworthy changes in version 0.4.1
101 -----------------------------------
102 * A secondary key is used when the primary key is specified but cannot
103 be used for the operation (if it is a sign-only key).
105 * GNUPG can now handle concatenated armored messages: There is still a
106 bug if different kinds of messages are mixed.
108 * Iterated+Salted passphrases now work. If want to be sure that PGP5
109 is able to handle them you may want to use the options
110 "--s2k-mode 3 --s2k-cipher-algo cast5 --s2k-digest-algo sha1"
111 when changing a passphrase.
113 * doc/OpenPGP talks about OpenPGP compliance, doc/HACKING gives
114 a few hints about the internal structure.
116 * Checked gnupg against the August 1998 draft (07) and I believe
117 it is in compliance with this document (except for one point).
119 * Fixed some bugs in the import merging code and rewrote some
120 code for the trustdb.
123 Noteworthy changes in version 0.4.0
124 -----------------------------------
125 * Triple DES is now supported. Michael Roth did this piece of
126 needed work. We have now all the coded needed to be OpenPGP
129 * Added a simple rpm spec file (see INSTALL).
131 * detached and armored signatures are now using "PGP SIGNATURE",
132 except when --rfc1991 is used.
134 * All times which are not in the yyy-mm-dd format are now printed
138 Noteworthy changes in version 0.3.5
139 -----------------------------------
140 * New option --throw-keyid to create anonymous enciphered messages.
141 If gpg detects such a message it tires all available secret keys
142 in turn so decode it. This is a gnupg extension and not in OpenPGP
143 but it has been discussed there and afaik some products use this
144 scheme too (Suggested by Nimrod Zimmerman).
146 * Fixed a bug with 5 byte length headers.
148 * --delete-[secret-]key is now also availabe in gpgm.
150 * cleartext signatures are not anymore converted to LF only.
152 * Fixed a trustdb problem. Run "gpgm --check-trustdb" to fix old
155 * Building in another directory should now work.
157 * Weak key detection mechanism (Niklas Hernaeus).
160 Noteworthy changes in version 0.3.4
161 -----------------------------------
162 * New options --comment and --set-filename; see g10/OPTIONS
164 * yes/no, y/n localized.
168 Noteworthy changes in version 0.3.3
169 -----------------------------------
170 * IMPORTANT: I found yet another bug in the way the secret keys
171 are encrypted - I did it the way pgp 2.x did it, but OpenPGP
172 and pgp 5.x specifiy another (in some aspects simpler) method.
173 To convert your secret keys you have to do this:
174 1. Build the new release but don't install it and keep
175 a copy of the old program.
176 2. Disable the network, make sure that you are the only
177 user, be sure that there are no trojan horses etc ....
178 3. Use your old gpg (version 0.3.[12]) and set the
179 passphrases of ALL your secret keys to empty!
180 (gpg --change-passphrase your-user-id).
181 4. Save your ownertrusts (see the next point)
182 5. rm ~/.gnupg/trustd.gpg
183 6. install the new version of gpg (0.3.3)
184 7. For every secret key call "gpg --edit-key your-user-id",
185 enter "passwd" at the prompt, follow the instructions and
186 change your passward back, enter "save" to store it.
187 8. Restore the ownertrust (see next point).
189 * The format of the trust database has changed; you must delete
190 the old one, so gnupg can create a new one.
191 IMPORTANT: Use version 0.3.[12] to save your assigned ownertrusts
192 ("gpgm --list-ownertrust >saved-trust"); then build this new version
193 and restore the ownertrust with this new version
194 ("gpgm --import-ownertrust saved-trust"). Please note that
195 --list-ownertrust has been renamed to --export-ownertrust in this
196 release and it does now only export defined ownertrusts.
198 * The command --edit-key now provides a commandline driven menu
199 which can be used vor vaious tasks. --sign-key is only an
200 an alias to --edit-key and maybe removed in future: use the
201 command "sign" of this new menu - you can select which user ids
204 * Alternate user ids can now be created an signed.
206 * Owner trust values can now be changed with --edit-key (trust)
208 * GNUPG can now run as a coprocess; this enables sophisticated
209 frontends. tools/shmtest.c is a simple sample implemenation.
210 This needs some more work: all tty_xxx() are to be replaced
211 by cpr_xxx() and some changes in the display logics is needed.
213 * Removed options --gen-prime and --gen-random.
215 * Removed option --add-key; use --edit-key instead.
217 * Removed option --change-passphrase; use --edit-key instead.
219 * Signatures are now checked even if the output file could not
220 be created. Command "--verify" tries to find the detached data.
222 * gpg now disables core dumps.
224 * compress and symmetric cipher preferences are now used.
225 Because there is no 3DES yet, this is replaced by Blowfish.
227 * We have added the Twofish as an experimental cipher algorithm.
228 Many thanks to Matthew Skala for doing this work.
229 Twofish is the AES submission from Schneier et al.; see
230 "www.counterpane.com/twofish.html" for more information.
232 * Started with a help system: If you enter a question mark at some
233 prompt; you should get a specific help for this prompt.
235 * There is no more backup copy of the secret keyring.
237 * A lot of new bugs. I think this release is not as stable as
241 Noteworthy changes in version 0.3.2
242 -----------------------------------
243 * Fixed some bugs when using --textmode (-seat)
245 * Now displays the trust status of a positive verified message.
247 * Keyrings are now scanned in the sequence they are added with
248 --[secret-]keyring. Note that the default keyring is implictly
249 added as the very first one unless --no-default-keyring is used.
251 * Fixed setuid and dlopen bug.
253 Noteworthy changes in version 0.3.1
254 -----------------------------------
255 * Partial headers are now written in the OpenPGP format if
256 a key in a v4 packet is used.
258 * Removed some unused options, removed the gnupg.sig stuff.
260 * Key lookup by name now returns a key which can be used for
263 * New options --list-ownertrust (gpgm) to make a backup copy
264 of the ownertrust values you assigned.
266 * clear signature headers are now in compliance with OpenPGP.
268 Noteworthy changes in version 0.3.0
269 -----------------------------------
271 * New option --emulate-checksum-bug. If your passphrase does not
272 work anymore, use this option and --change-passphrase to rewrite
275 * More complete v4 key support: Preferences and expiration time
276 is set into the self signature.
278 * Key generation defaults to DSA/ElGamal keys, so that new keys are
279 interoperable with pgp5
281 * DSA key generation is faster and key generation does not anymore
282 remove entropy from the random generator (the primes are public
283 parameters, so there is really no need for a cryptographic secure
284 prime number generator which we had used).
286 * A complete new structure for representing the key parameters.
288 * Removed most public key knowledge into the cipher libray.
290 * Support for dynamic loading of new algorithms.
292 * Moved tiger to an extension module.
295 Noteworthy changes in version 0.2.19
296 ------------------------------------
298 * Replaced /dev/urandom in checks with new tool mk-tdata.
300 * Some assembler file cleanups; some more functions for the Alpha.
302 * Tiger has now the OpenPGP assigned number 6. Because the OID has
303 changed, old signatures using this algorithm can't be verified.
305 * gnupg now encrypts the compressed packed and not any longer in the
306 reverse order; anyway it can decrypt both versions. Thanks to Tom
307 for telling me this (not security related) bug.
309 * --add-key works and you are now able to generate subkeys.
311 * It is now possible to generate ElGamal keys in v4 packets to create
314 * Some new features for better integration into MUAs.
317 Noteworthy changes in version 0.2.18
318 ------------------------------------
320 * Splitted cipher/random.c, add new option "--disable-dev-random"
321 to configure to support the development of a random source for
322 other systems. Prepared sourcefiles rand-unix.c, rand-w32.c
323 and rand-dummy.c (which is used to allow compilation on systems
324 without a random source).
326 * Fixed a small bug in the key generation (it was possible that 48 bits
327 of a key were not taken from the random pool)
329 * Add key generation for DSA and v4 signatures.
331 * Add a function trap_unaligned(), so that a SIGBUS is issued on
332 Alphas and not the slow emulation code is used. And success: rmd160
335 * Enhanced the formatting facility of argparse and changed the use of
336 \r,\v to @ because gettext does not like it.
338 * New option "--compress-algo 1" to allow the creation of compressed
339 messages which are readable by PGP and "--print-md" (gpgm) to make
340 speed measurement easier.
343 Noteworthy changes in version 0.2.17
344 ------------------------------------
346 * Comment packets are now of private type 61.
348 * Passphrase code still used a 160 bit blowfish key, added a
349 silly workaround. Please change your passphrase again - sorry.
351 * Conventional encryption now uses a type 3 packet to describe the
354 * The new algorithm number for Blowfish is 20, 16 is still used for
355 encryption only; for signing it is only used when it is in a v3 packet,
356 so that GNUPG keys are still valid.
359 Noteworthy changes in version 0.2.16
360 ------------------------------------
362 * Add experimental support for the TIGER/192 message diigest algorithm.
363 (But there is only a dummy ASN OID).
365 * Standard cipher is now Blowfish with 128 bit key in OpenPGP's CFB
366 mode. I renamed the old cipher to Blowfish160. Because the OpenPGP
367 group refused to assign me a number for Blowfish160, I have to
368 drop support for this in the future. You should use
369 "--change-passphrase" to recode your current passphrase with 128
373 Noteworthy changes in version 0.2.15
374 ------------------------------------
376 * Fixed a bug with the old checksum calculation for secret keys.
377 If you run the program without --batch, a warning does inform
378 you if your secret key needs to be converted; simply use
379 --change-passphrase to recalculate the checksum. Please do this
380 soon, as the compatible mode will be removed sometime in the future.
382 * CAST5 works (using the PGP's special CFB mode).
384 * Again somewhat more PGP 5 compatible.
386 * Some new test cases
388 Noteworthy changes in version 0.2.14
389 ------------------------------------
391 * Changed the internal handling of keyrings.
393 * Add support to list PGP 5 keyrings with supkeys
395 * Timestamps of signatures are now verified.
397 * A expiration time can now be specified during key generation.
399 * Some speedups for Blowfish and SHA-1, rewrote SHA-1 transform.
400 Reduced the amount of random bytes needed for key generation in
404 Noteworthy changes in version 0.2.13
405 ------------------------------------
407 * Verify of DSA signatures works.
409 * Re-implemented the slower random number generator.
412 Noteworthy changes in version 0.2.12
413 ------------------------------------
415 * --delete-key checks that there is no secret key. The new
416 option --delete-secret-key maybe used to delete a secret key.
418 * "-kv" now works as expected. Options "--list-{keys,sigs]"
419 and "--check-sigs" are now working.
421 * New options "--verify" and "--decrypt" to better support integration
422 into MUAs (partly done for Mutt).
424 * New option "--with-colons" to make parsing of key lists easier.
426 Noteworthy changes in version 0.2.11
427 ------------------------------------
429 * GPG now asks for a recipient's name if option "-r" is not used.
431 * If there is no good trust path, the program asks whether to use
432 the public keys anyway.
434 * "--delete-key" works for public keys. What semantics shall I use
435 when there is a secret key too? Delete the secret key or leave him
436 and auto-regenerate the public key, netxt time the secret key is used?
438 Noteworthy changes in version 0.2.10
439 ------------------------------------
441 * Code for the alpha is much faster (about 20 times); the data
442 was misaligned and the kernel traps this, so nearly all time
443 was used by system to trap the misalignments and to write
444 syslog messages. Shame on me and thanks to Ralph for
445 pointing me at this while drinking some beer yesterday.
447 * Changed some configure options and add an option
448 --disable-m-guard to remove the memory checking code
449 and to compile everthing with optimization on.
451 * New environment variable GNUPGHOME, which can be used to set
452 another homedir than ~/.gnupg. Changed default homedir for
453 Windoze version to c:/gnupg.
455 * Fixed detached signatures; detached PGP signatures caused a SEGV.
457 * The Windoze version works (as usual w/o a strong RNG).
460 Noteworthy changes in version 0.2.9
461 -----------------------------------
465 * Added a simple man page.
467 * Switched to automake1.2f and a newer gettext.
469 Noteworthy changes in version 0.2.8
470 -----------------------------------
472 * Changed the name to GNUPG, the binaries are called gpg and gpgm.
473 You must rename rename the directory "~/.g10" to ~/.gnupg/, rename
474 {pub,sec}ring.g10 to {pub,sec}ring.gpg, trustdb.g10 to trustdb.gpg
475 and g10.sig to gnupg.sig.
477 * New or changed passphrases are now salted.
480 Noteworthy changes in version 0.2.7
481 -----------------------------------
483 * New command "gen-revoke" to create a key revocation certificate.
485 * New option "homedir" to set the homedir (which defaults to "~/.g10").
486 This directory is created if it does not exists (only the last
487 part of the name and not the complete hierarchy)
489 * Command "import" works. (Try: "finger gcrypt@ftp.guug.de|g10 --import")
491 * New commands "dearmor/enarmor" for g10maint. These are mainly
492 used for internal test purposes.
494 * Option --version now conforming to the GNU standards and lists
495 the available ciphers, message digests and public key algorithms.
497 * Assembler code for m68k (not tested).
499 * "make check" works.
501 Noteworthy changes in version 0.2.6
502 -----------------------------------
504 * Option "--export" works.
507 Noteworthy changes in version 0.2.5
508 -----------------------------------
510 * Added zlib for systems which don't have it.
511 Use "./configure --with-zlib" to link with the static version.
513 * Generalized some more functions and rewrote the encoding of
514 message digests into MPIs.
516 * Enhanced the checkit script
519 Noteworthy changes in version 0.2.4
520 -----------------------------------
522 * nearly doubled the speed of the ElGamal signature verification.
524 * backup copies of keyrings are created.
526 * assembler stuff for Pentium; gives about 15% better perfomance.
528 * fixed a lot of bugs.
531 Noteworthy changes in version 0.2.3
532 -----------------------------------
534 * Found a bug in the calculation of ELG fingerprints. This is now
535 fixed, but all existing fingerprints and keyids for ELG keys
536 are not any more valid.
538 * armor should now work; including clear signed text.
540 * moved some options to the new program g10maint
542 * It's now 64 bit clean and runs fine on an alpha--linux.
544 * Key generation is much faster now. I fixed this by using not
545 so strong random number for the primes (this was a bug because the
546 ElGamal primes are public parameters and it does not make sense
547 to generate them from strong random). The real secret is the x value
548 which is still generated from strong (okay: /dev/random) random bits.
550 * added option "--status-fd": see g10/OPTIONS
552 * We have secure memeory on systems which support mlock().
553 It is not complete yet, because we do not have signal handler
554 which does a cleanup in very case.
555 We should also check the ulimit for the user in the case
556 that the admin does not have set a limit on locked pages.
558 * started with internationalization support.
560 * The logic to handle the web of trust is now implemented. It is
561 has some bugs; but I'm going to change the algorithm anyway.
562 It works by calculating the trustlevel on the fly. It may ask
563 you to provide trust parameters if the calculated trust probability
564 is too low. I will write a paper which discusses this new approach.
566 * a couple of changes to the configure script.
568 * New option "--quick-random" which uses a much quicker random
569 number generator. Keys generated while this option is in effect
570 are flags with "INSECURE!" in the user-id. This is a development
573 * Read support for new version packets (OpenPGP).
575 * Comment packets are now of correct OpenPGP type 16. Old comment
576 packets written by G10 are detected because they always start with
577 a hash which is an invalid version byte.
579 * The string "(INSECURE!)" is appended to a new user-id if this
580 is generated on a system without a good random number generator.
