In the past this was only supported on W32; on non-W32 systems the new configure option --disable-standard-socket may now be used to disable this new default. * agent: New and changed passphrases are now created with an iteration count requiring about 100ms of CPU work. * dirmngr: Dirmngr is now a part of this package. It is now also expected to run as a system service and the configuration directories are changed to the GnuPG name space. [Update: 2.1.0 starts dirmngr on demand as user daemon.] * Support for Windows CE. [Update: This has not been tested for the 2.1.0 release] * Numerical values may now be used as an alternative to the debug-level keywords.

New option --p12-charset for gpgsm. * Improved the libgcrypt logging support in all modules. Noteworthy changes in version 2.0.3 (2007-03-08) ------------------------------------------------ * By default, do not allow processing multiple plaintexts in a single stream. Many programs that called GnuPG were assuming that GnuPG did not permit this, and were thus not using the plaintext boundary status tags that GnuPG provides. This change makes GnuPG reject such messages by default which makes those programs safe again. --allow-multiple-messages returns to the old behavior. [CVE-2007-1263]. * New --verify-option show-primary-uid-only. * gpgconf may now reads a global configuration file to select which options are changeable by a frontend. The new applygnupgdefaults tool may be used by an admin to set default options for all users. * The PIN pad of the Cherry XX44 keyboard is now supported. The DINSIG and the NKS applications are now also aware of PIN pads. Noteworthy changes in version 2.0.2 (2007-01-31) ------------------------------------------------ * Fixed a serious and exploitable bug in processing encrypted packages. [CVE-2006-6235]. * Added --passphrase-repeat to set the number of times GPG will prompt for a new passphrase to be repeated. This is useful to help memorize a new passphrase. The default is 1 repetition. * Using a PIN pad does now also work for the signing key. * A warning is displayed by gpg-agent if a new passphrase is too short. New option --min-passphrase-len defaults to 8. * The status code BEGIN_SIGNING now shows the used hash algorithms. Noteworthy changes in version 2.0.1 (2006-11-28) ------------------------------------------------ * Experimental support for the PIN pads of the SPR 532 and the Kaan Advanced card readers. Add "disable-keypad" scdaemon.conf if you don't want it. Does currently only work for the OpenPGP card and its authentication and decrypt keys. * Fixed build problems on some some platforms and crashes on amd64. * Fixed a buffer overflow in gpg2.

Noteworthy changes in version 1.9.92 (2006-10-11) ------------------------------------------------- * Bug fixes. Noteworthy changes in version 1.9.91 (2006-10-04) ------------------------------------------------- * New "relax" flag for trustlist.txt to allow root CA certificates without BasicContraints. * [gpg2] Removed the -k PGP 2 compatibility hack. -k is now an alias for --list-keys. * [gpg2] Print a warning if "-sat" is used instead of "--clearsign". Noteworthy changes in version 1.9.90 (2006-09-25) ------------------------------------------------- * Made readline work for gpg. * Cleanups und minor bug fixes. * Included translations from gnupg 1.4.5. Noteworthy changes in version 1.9.23 (2006-09-18) ------------------------------------------------- * Regular man pages for most tools are now build directly from the Texinfo source. * The gpg code from 1.4.5 has been fully merged into this release. The configure option --enable-gpg is still required to build this gpg part. For production use of OpenPGP the gpg version 1.4.5 is still recommended. Note, that gpg will be installed under the name gpg2 to allow coexisting with an 1.4.x gpg. * API change in gpg-agent's pkdecrypt command. Thus an older gpgsm may not be used with the current gpg-agent. * The scdaemon will now call a script on reader status changes. * gpgsm now allows file descriptor passing for "INPUT", "OUTPUT" and "MESSAGE". * The gpgsm server may now output a key listing to the output file handle. This needs to be enabled using "OPTION list-to-output=1". * The --output option of gpgsm has now an effect on list-keys. * New gpgsm commands --dump-chain and list-chain. * gpg-connect-agent has new options to utilize descriptor passing. * A global trustlist may now be used. See doc/examples/trustlist.txt. * When creating a new pubring.kbx keybox common certificates are imported. Noteworthy changes in version 1.9.22 (2006-07-27) ------------------------------------------------- * Enhanced pkcs#12 support to allow import from simple keyBags. * Exporting to pkcs#12 now create bag attributes so that Mozilla is able to import the files. * Fixed uploading of certain keys to the smart card. Noteworthy changes in version 1.9.21 (2006-06-20) ------------------------------------------------- * New command APDU for scdaemon to allow using it for general card access. Might be used through gpg-connect-agent by using the SCD prefix command. * Support for the CardMan 4040 PCMCIA reader (Linux 2.6.15 required). * Scdaemon does not anymore reset cards at the end of a connection. * Kludge to allow use of Bundesnetzagentur issued X.509 certificates. * Added --hash=xxx option to scdaemon's PKSIGN command. * Pkcs#12 files are now created with a MAC. This is for better interoperability. * Collected bug fixes and minor other changes. Noteworthy changes in version 1.9.20 (2005-12-20) ------------------------------------------------- * Importing pkcs#12 files created be recent versions of Mozilla works again. * Basic support for qualified signatures. * New debug tool gpgparsemail. Noteworthy changes in version 1.9.19 (2005-09-12) ------------------------------------------------- * The Belgian eID card is now supported for signatures and ssh. Other pkcs#15 cards should work as well. * Fixed bug in --export-secret-key-p12 so that certificates are again included. Noteworthy changes in version 1.9.18 (2005-08-01) ------------------------------------------------- * [gpgsm] Now allows for more than one email address as well as URIs and dnsNames in certificate request generation. A keygrip may be given to create a request from an existing key. * A couple of minor bug fixes. Noteworthy changes in version 1.9.17 (2005-06-20) ------------------------------------------------- * gpg-connect-agent has now features to handle Assuan INQUIRE commands. * Internal changes for OpenPGP cards. New Assuan command WRITEKEY. * GNU Pth is now a hard requirement. * [scdaemon] Support for OpenSC has been removed. Instead a new and straightforward pkcs#15 modules has been written. As of now it does allows only signing using TCOS cards but we are going to enhance it to match all the old capabilities. * [gpg-agent] New option --write-env-file and Assuan command UPDATESTARTUPTTY. * [gpg-agent] New option --default-cache-ttl-ssh to set the TTL for SSH passphrase caching independent from the other passphrases. Noteworthy changes in version 1.9.16 (2005-04-21) ------------------------------------------------- * gpg-agent does now support the ssh-agent protocol and thus allows to use the pinentry as well as the OpenPGP smartcard with ssh. * New tool gpg-connect-agent as a general client for the gpg-agent. * New tool symcryptrun as a wrapper for certain encryption tools. * The gpg tool is not anymore build by default because those gpg versions available in the gnupg 1.4 series are far more matured. Noteworthy changes in version 1.9.15 (2005-01-13) ------------------------------------------------- * Fixed passphrase caching bug. * Better support for CCID readers; the reader from Cherry RS 6700 USB does now work. Noteworthy changes in version 1.9.14 (2004-12-22) ------------------------------------------------- * [gpg-agent] New option --use-standard-socket to allow the use of a fixed socket. gpgsm falls back to this socket if GPG_AGENT_INFO has not been set. * Ported to MS Windows with some functional limitations. * New tool gpg-preset-passphrase. Noteworthy changes in version 1.9.13 (2004-12-03) ------------------------------------------------- * [gpgsm] New option --prefer-system-dirmngr. * Minor cleanups and debugging aids. Noteworthy changes in version 1.9.12 (2004-10-22) ------------------------------------------------- * [scdaemon] Partly rewrote the PC/SC code. * Removed the sc-investigate tool. It is now in a separate package available at ftp://ftp.g10code.com/g10code/gscutils/ . * [gpg-agent] Fixed logging problem. Noteworthy changes in version 1.9.11 (2004-10-01) ------------------------------------------------- * When using --import along with --with-validation, the imported certificates are validated and only imported if they are fully valid. * [gpg-agent] New option --max-cache-ttl. * [gpg-agent] When used without --daemon or --server, gpg-agent now check whether a agent is already running and usable. * Fixed some i18n problems. Noteworthy changes in version 1.9.10 (2004-07-22) ------------------------------------------------- * Fixed a serious bug in the checking of trusted root certificates. * New configure option --enable-agent-pnly allows to build and install just the agent. * Fixed a problem with the log file handling. Noteworthy changes in version 1.9.9 (2004-06-08) ------------------------------------------------ * [gpg-agent] The new option --allow-mark-trusted is now required to allow gpg-agent to add a key to the trustlist.txt after user confirmation. * Creating PKCS#10 requests does now honor the key usage. Noteworthy changes in version 1.9.8 (2004-04-29) ------------------------------------------------ * [scdaemon] Overhauled the internal CCID driver. * [scdaemon] Status files named ~/.gnupg/reader_.status are now written when using the internal CCID driver. * [gpgsm] New commands --dump-{,secret,external}-keys to show a very detailed view of the certificates. * The keybox gets now compressed after 3 hours and ephemeral stored certificates are deleted after about a day. * [gpg] Usability fixes for --card-edit. Note, that this has already been ported back to gnupg-1.3 Noteworthy changes in version 1.9.7 (2004-04-06) ------------------------------------------------ * Instrumented the modules for gpgconf. * Added support for DINSIG card applications. * Include the smimeCapabilities attribute with signed messages. * Now uses the gettext domain "gnupg2" to avoid conflicts with gnupg versions < 1.9. Noteworthy changes in version 1.9.6 (2004-03-06) ------------------------------------------------ * Code cleanups and bug fixes. Noteworthy changes in version 1.9.5 (2004-02-21) ------------------------------------------------ * gpg-protect-tool gets now installed into libexec as it ought to be. Cleaned up the build system to better comply with the coding standards. * [gpgsm] The --import command is now able to autodetect pkcs#12 files and import secret and private keys from this file format. A new command --export-secret-key-p12 is provided to allow exporting of secret keys in PKCS\#12 format. * [gpgsm] The pinentry will now present a description of the key for whom the passphrase is requested. * [gpgsm] New option --with-validation to check the validity of key while listing it. * New option --debug-level={none,basic,advanced,expert,guru} to map the debug flags to sensitive levels on a per program base. Noteworthy changes in version 1.9.4 (2004-01-30) ------------------------------------------------ * Added support for the Telesec NKS 2.0 card application. * Added simple tool addgnupghome to create .gnupg directories from /etc/skel/.gnupg. * Various minor bug fixes and cleanups; mainly gpgsm and gpg-agent related. Noteworthy changes in version 1.9.3 (2003-12-23) ------------------------------------------------ * New gpgsm options --{enable,disable}-ocsp to validate keys using OCSP. This option requires a not yet released DirMngr version. Default is disabled. * The --log-file option may now be used to print logs to a socket. Prefix the socket name with "socket://" to enable this. This does not work on all systems and falls back to stderr if there is a problem with the socket. * The options --encrypt-to and --no-encrypt-to now work the same in gpgsm as in gpg. Note, they are also used in server mode. * Duplicated recipients are now silently removed in gpgsm. Noteworthy changes in version 1.9.2 (2003-11-17) ------------------------------------------------ * On card key generation is no longer done using the --gen-key command but from the menu provided by the new --card-edit command. * PINs are now properly cached and there are only 2 PINs visible. The 3rd PIN (CHV2) is internally syncronized with the regular PIN. * All kind of other internal stuff. Noteworthy changes in version 1.9.1 (2003-09-06) ------------------------------------------------ * Support for OpenSC is back. scdaemon supports a --disable-opensc to disable OpenSC use at runtime, so that PC/SC or ct-API can still be used directly. * Rudimentary support for the SCR335 smartcard reader using an internal driver. Requires current libusb from CVS. * Bug fixes. Noteworthy changes in version 1.9.0 (2003-08-05) ------------------------------------------------ ====== PLEASE SEE README-alpha ======= * gpg has been renamed to gpg2 and gpgv to gpgv2. This is a temporary change to allow co-existing with stable gpg versions. * ~/.gnupg/gpg.conf-1.9.0 is fist tried as config file before the usual gpg.conf. * Removed the -k, -kv and -kvv commands. -k is now an alias to --list-keys. New command -K as alias for --list-secret-keys. * Removed --run-as-shm-coprocess feature. * gpg does now also use libgcrypt, libgpg-error is required. * New gpgsm commands --call-dirmngr and --call-protect-tool. * Changing a passphrase is now possible using "gpgsm --passwd" * The content-type attribute is now recognized and created. * The agent does now reread certain options on receiving a HUP. * The pinentry is now forked for each request so that clients with different environments are supported. When running in daemon mode and --keep-display is not used the DISPLAY variable is ignored. * Merged stuff from the newpg branch and started this new development branch. Version 1.4.19 (2015-02-27) Version 1.4.18 (2014-06-30) Version 1.4.17 (2014-06-23) Version 1.4.16 (2013-12-18) Version 1.4.15 (2013-10-04) Version 1.4.14 (2013-07-25) Version 1.4.13 (2012-12-20) Version 1.4.12 (2012-01-30) Version 1.4.11 (2010-10-18) Version 1.4.10 (2009-09-02) Version 1.4.9 (2008-03-26) Version 1.4.8 (2007-12-20) Version 1.4.7 (2007-03-05) Version 1.4.6 (2006-12-06) Version 1.4.5 (2006-08-01) Version 1.4.4 (2006-06-25) Version 1.4.3 (2006-04-03) Version 1.4.2 (2005-07-26) Version 1.4.1 (2005-03-15) Version 1.4.0 (2004-12-16) Noteworthy changes in version 1.3.2 (2003-05-27) ------------------------------------------------ * New "--gnupg" option (set by default) that disables --openpgp, and the various --pgpX emulation options. This replaces --no-openpgp, and --no-pgpX, and also means that GnuPG has finally grown a --gnupg option to make GnuPG act like GnuPG. * A bug in key validation has been fixed. This bug only affects keys with more than one user ID (photo IDs do not count here), and results in all user IDs on a given key being treated with the validity of the most-valid user ID on that key. * Notation names that do not contain a '@' are no longer allowed unless --expert is set. This is to help prevent pollution of the (as yet unused) IETF notation namespace. * Multiple trust models are now supported via the --trust-model option. The options are "pgp" (web-of-trust plus trust signatures), "classic" (web-of-trust only), and "always" (identical to the --always-trust option). * The --personal-{cipher|digest|compression}-preferences are now consulted to get default algorithms before resorting to the last-ditch defaults of --s2k-cipher-algo, SHA1, and ZIP respectively. This allows a user to set algorithms to use in a safe manner so they are used when legal to do so, without forcing them on for all messages. * New --primary-keyring option to designate the keyring that the user wants new keys imported into. * --s2k-digest-algo is now used for all password mangling. Earlier versions used both --s2k-digest-algo and --digest-algo for passphrase mangling. * Handling of --hidden-recipient or --throw-keyid messages is now easier - the user only needs to give their passphrase once, and GnuPG will try it against all of the available secret keys. * Care is taken to prevent compiler optimization from removing memory wiping code. * New option --no-mangle-dos-filenames so that filenames are not truncated in the W32 version. * A "convert-from-106" script has been added. This is a simple script that automates the conversion from a 1.0.6 or earlier version of GnuPG to a 1.0.7 or later version. * Disabled keys are now skipped when selecting keys for encryption. If you are using the --with-colons key listings to detect disabled keys, please see doc/DETAILS for a minor format change in this release. * Minor trustdb changes to make the trust calculations match common usage. * New command "revuid" in the --edit-key menu to revoke a user ID. This is a simpler interface to the old method (which still works) of revoking the user ID self-signature. * Status VALIDSIG does now also print the primary key's fingerprint, as well as the signature version, pubkey algorithm, hash algorithm, and signature class. * Add read-only support for the SHA-256 hash, and optional read-only support for the SHA-384 and SHA-512 hashes. * New option --enable-progress-filter for use with frontends. * DNS SRV records are used in HKP keyserver lookups to allow administrators to load balance and select keyserver ports automatically. This is as specified in draft-shaw-openpgp-hkp-00.txt. * When using the "keyid!" syntax during a key export, only that specified key is exported. If the key in question is a subkey, the primary key plus only that subkey is exported. * configure --disable-xxx options to disable individual algorithms at build time. This can be used to build a smaller gpg binary for embedded uses where space is tight. See the README file for the algorithms that can be used with this option, or use --enable-minimal to build the smallest gpg possible (disables all optional algorithms, disables keyserver access, and disables photo IDs). * The keyserver no-modify flag on a key can now be displayed and modified. * Note that the TIGER/192 digest algorithm is in the process of being dropped from the OpenPGP standard. While this release of GnuPG still contains it, it is disabled by default. To ensure you will still be able to use your messages with future versions of GnuPG and other OpenPGP programs, please do not use this algorithm. Noteworthy changes in version 1.3.1 (2002-11-12) ------------------------------------------------ * Trust signature support. This is based on the Maurer trust model where a user can specify the trust level along with the signature with multiple levels so users can delegate certification ability to other users, possibly restricted by a regular expression on the user ID. Note that full trust signature support requires a regular expression parsing library. The regexp code from glibc 2.3.1 is included for those platforms that don't have working regexp functions available. The configure option --disable-regex may be used to disable any regular expression code, which will make GnuPG ignore any trust signature with a regular expression included. * Two new commands --hidden-recipient (-R) and --hidden-encrypt-to encrypt to a user, but hide the identity of that user. This is the same functionality as --throw-keyid, but can be used on a per-user basis. * Full algorithm names (e.g. "3DES", "SHA1", "ZIP") can now be used interchangeably with the short algorithm names (e.g. "S2", "H2", "Z1") anywhere algorithm names are used in GnuPG. Noteworthy changes in version 1.3.0 (2002-10-18) ------------------------------------------------ * The last piece of internal keyserver support has been removed, and now all keyserver access is done via the keyserver plugins. There is also a newer keyserver protocol used between GnuPG and the plugins, so plugins from earlier versions of GnuPG may not work properly. * The HKP keyserver plugin supports the new machine-readable key listing format for those keyservers that provide it. * When using a HKP keyserver with multiple DNS records (such as wwwkeys.pgp.net which has the addresses of multiple servers around the world), try all records until one succeeds. Note that it depends on the LDAP library used whether the LDAP keyserver plugin does this as well. * The library dependencies for OpenLDAP seem to change fairly frequently, and GnuPG's configure script cannot guess all the combinations. Use ./configure LDAPLIBS="-L libdir -l libs" to override the script and use the libraries selected. * Secret keys generated with --export-secret-subkeys are now indicated in key listings with a '#' after the "sec", and in --with-colons listings by showing no capabilities (no lowercase characters). * --trusted-key has been un-obsoleted, as it is useful for adding ultimately trusted keys from the config file. It is identical to using --edit and "trust" to change a key to ultimately trusted. * Translations other than de are no longer distributed with the development branch. This is due to the frequent text changes during development, which cause the translations to rapidly go out of date. Version 1.2.8 (2006-12-07) Version 1.2.7 (2004-12-27) Version 1.2.6 (2004-08-25) Version 1.2.5 (2004-07-26) Version 1.2.4 (2003-12-23) Version 1.2.3 (2003-08-21) Version 1.2.2 (2003-05-01) Version 1.2.1 (2002-10-25) Version 1.2.0 (2002-09-21) Noteworthy changes in version 1.1.92 (2002-09-11) ------------------------------------------------- * [IMPORTANT] The default configuration file is now ~/.gnupg/gpg.conf. If an old ~/.gnupg/options is found it will still be used. This change is required to have a more consistent naming scheme with forthcoming tools. * The use of MDCs have increased. A MDC will be used if the recipients directly request it, if the recipients have AES, AES192, AES256, or TWOFISH in their cipher preferences, or if the chosen cipher has a blocksize not equal to 64 bits (currently this is also AES, AES192, AES256, and TWOFISH). * GnuPG will no longer automatically disable compression when processing an already-compressed file unless a MDC is being used. This is to give the message a certain amount of resistance to the chosen-ciphertext attack while communicating with other programs (most commonly PGP earlier than version 7.x) that do not support MDCs. * The option --interactive now has the desired effect when importing keys. * The file permission and ownership checks on files have been clarified. Specifically, the homedir (usually ~/.gnupg) is checked to protect everything within it. If the user specifies keyrings outside this homedir, they are presumed to be shared keyrings and therefore *not* checked. Configuration files specified with the --options option and the IDEA cipher extension specified with --load-extension are checked, along with their enclosing directories. * The configure option --with-static-rnd=auto allows to build gpg with all available entropy gathering modules included. At runtime the best usable one will be selected from the list linux, egd, unix. This is also the default for systems lacking a /dev/random device. * The default character set is now taken from the current locale; it can still be overridden by the --charset option. Using the option -vvv shows the used character set. * [REMOVED] --emulate-checksum-bug and --emulate-3des-s2k-bug have been removed. Noteworthy changes in version 1.1.91 (2002-08-04) ------------------------------------------------- * All modules are now linked statically; the --load-extension option is in general not useful anymore. The only exception is to specify the deprecated idea cipher. * The IDEA plugin has changed. Previous versions of the IDEA plugin will no longer work with GnuPG. However, the current version of the plugin will work with earlier GnuPG versions. * When using --batch with one of the --delete-key commands, the key must be specified by fingerprint. See the man page for details. * There are now various ways to restrict the ability GnuPG has to exec external programs (for the keyserver helpers or photo ID viewers). Read the README file for the complete list. * New export option to leave off attribute packets (photo IDs) during export. This is useful when exporting to HKP keyservers which do not understand attribute packets. * New import option to repair during import the HKP keyserver mangling multiple subkeys bug. Note that this cannot completely repair the damaged key as some crucial data is removed by the keyserver, but it does at least give you back one subkey. This is on by default for keyserver --recv-keys, and off by default for regular --import. * The keyserver helper programs now live in /usr/[local/]libexec/gnupg by default. If you are upgrading from 1.0.7, you might want to delete your old copies in /usr/[local/]bin. If you use an OS that does not use libexec for whatever reason, use configure --libexecdir=/usr/local/lib to place the keyserver helpers there. * The LDAP keyserver handler now works properly with very old (version 1) LDAP keyservers. Noteworthy changes in version 1.1.90 (2002-07-01) ------------------------------------------------- * New commands: --personal-cipher-preferences, --personal-digest-preferences, and --personal-compress-preferences allow the user to specify which algorithms are to be preferred. Note that this does not permit using an algorithm that is not present in the recipient's preferences (which would violate the OpenPGP standard). This just allows sorting the preferences differently. * New "group" command to refer to several keys with one name. * A warning is issued if the user forces the use of an algorithm that is not listed in the recipient's preferences. * Full revocation key (aka "designated revoker") support. * The preferred hash algorithms on a key are consulted when encrypting a signed message to that key. Note that this is disabled by default by a SHA1 preference in --personal-digest-preferences. * --cert-digest-algo allows the user to specify the hash algorithm to use when signing a key rather than the default SHA1 (or MD5 for PGP2 keys). Do not use this feature unless you fully understand the implications of this. * --pgp7 mode automatically sets all necessary options to ensure that the resulting message will be usable by a user of PGP 7.x. * New --attribute-fd command for frontends and scripts to get the contents of attribute packets (i.e. photos) * In expert mode, the user can now re-sign a v3 key with a v4 self-signature. This does not change the v3 key into a v4 key, but it does allow the user to use preferences, primary ID flags, etc. * Significantly improved photo ID support on non-unixlike platforms. * The version number has jumped ahead to 1.1.90 to skip over the old version 1.1 and to get ready for the upcoming 1.2. * ElGamal sign and encrypt is not anymore allowed in the key generation dialog unless in expert mode. RSA sign and encrypt has been added with the same restrictions. * [W32] Keyserver access does work with Windows NT. Noteworthy changes in version 1.0.7 (2002-04-29) ------------------------------------------------ * Secret keys are now stored and exported in a new format which uses SHA-1 for integrity checks. This format renders the Rosa/Klima attack useless. Other OpenPGP implementations might not yet support this, so the option --simple-sk-checksum creates the old vulnerable format. * The default cipher algorithm for encryption is now CAST5, default hash algorithm is SHA-1. This will give us better interoperability with other OpenPGP implementations. * Symmetric encrypted messages now use a fixed file size if possible. This is a tradeoff: it breaks PGP 5, but fixes PGP 2, 6, and 7. Note this was only an issue with RFC-1991 style symmetric messages. * Photographic user ID support. This uses an external program to view the images. * Enhanced keyserver support via keyserver "plugins". GnuPG comes with plugins for the NAI LDAP keyserver as well as the HKP email keyserver. It retains internal support for the HKP HTTP keyserver. * Nonrevocable signatures are now supported. If a user signs a key nonrevocably, this signature cannot be taken back so be careful! * Multiple signature classes are usable when signing a key to specify how carefully the key information (fingerprint, photo ID, etc) was checked. * --pgp2 mode automatically sets all necessary options to ensure that the resulting message will be usable by a user of PGP 2.x. * --pgp6 mode automatically sets all necessary options to ensure that the resulting message will be usable by a user of PGP 6.x. * Signatures may now be given an expiration date. When signing a key with an expiration date, the user is prompted whether they want their signature to expire at the same time. * Revocation keys (designated revokers) are now supported if present. There is currently no way to designate new keys as designated revokers. * Permissions on the .gnupg directory and its files are checked for safety. * --expert mode enables certain silly things such as signing a revoked user id, expired key, or revoked key. * Some fixes to build cleanly under Cygwin32. * New tool gpgsplit to split OpenPGP data formats into packets. * New option --preserve-permissions. * Subkeys created in the future are not used for encryption or signing unless the new option --ignore-valid-from is used. * Revoked user-IDs are not listed unless signatures are listed too or we are in verbose mode. * There is no default comment string with ascii armors anymore except for revocation certificates and --enarmor mode. * The command "primary" in the edit menu can be used to change the primary UID, "setpref" and "updpref" can be used to change the preferences. * Fixed the preference handling; since 1.0.5 they were erroneously matched against against the latest user ID and not the given one. * RSA key generation. * Merged Stefan's patches for RISC OS in. See comments in scripts/build-riscos. * It is now possible to sign and conventional encrypt a message (-cs). * The MDC feature flag is supported and can be set by using the "updpref" edit command. * The status messages GOODSIG and BADSIG are now returning the primary UID, encoded using %XX escaping (but with spaces left as spaces, so that it should not break too much) * Support for GDBM based keyrings has been removed. * The entire keyring management has been revamped. * The way signature stati are store has changed so that v3 signatures can be supported. To increase the speed of many operations for existing keyrings you can use the new --rebuild-keydb-caches command. * The entire key validation process (trustdb) has been revamped. See the man page entries for --update-trustdb, --check-trustdb and --no-auto-check-trustdb. * --trusted-keys is again obsolete, --edit can be used to set the ownertrust of any key to ultimately trusted. * A subkey is never used to sign keys. * Read only keyrings are now handled as expected. Noteworthy changes in version 1.0.6 (2001-05-29) ------------------------------------------------ * Security fix for a format string bug in the tty code. * Fixed format string bugs in all PO files. * Removed Russian translation due to too many bugs. The FTP server has an unofficial but better translation in the contrib directory. * Fixed expire time calculation and keyserver access. * The usual set of minor bug fixes and enhancements. * non-writable keyrings are now correctly handled. Noteworthy changes in version 1.0.5 (2001-04-29) ------------------------------------------------ * WARNING: The semantics of --verify have changed to address a problem with detached signature detection. --verify now ignores signed material given on stdin unless this is requested by using a "-" as the name for the file with the signed material. Please check all your detached signature handling applications and make sure that they don't pipe the signed material to stdin without using a filename together with "-" on the the command line. * WARNING: Corrected hash calculation for input data larger than 512M - it was just wrong, so you might notice bad signature in some very big files. It may be wise to keep an old copy of GnuPG around. * Secret keys are no longer imported unless you use the new option --allow-secret-key-import. This is a kludge and future versions will handle it in another way. * New command "showpref" in the --edit-key menu to show an easier to understand preference listing. * There is now the notation of a primary user ID. For example, it is printed with a signature verification as the first user ID; revoked user IDs are not printed there anymore. In general the primary user ID is the one with the latest self-signature. * New --charset=utf-8 to bypass all internal conversions. * Large File Support (LFS) is now working. * New options: --ignore-crc-error, --no-sig-create-check, --no-sig-cache, --fixed-list-mode, --no-expensive-trust-checks, --enable-special-filenames and --use-agent. See man page. * New command --pipemode, which can be used to run gpg as a co-process. Currently only the verification of detached signatures are working. See doc/DETAILS. * Keyserver support for the W32 version. * Rewritten key selection code so that GnuPG can better cope with multiple subkeys, expire dates and so. The drawback is that it is slower. * A whole lot of bug fixes. * The verification status of self-signatures are now cached. To increase the speed of key list operations for existing keys you can do the following in your GnuPG homedir (~/.gnupg): cp pubring.gpg pubring.gpg.save && gpg --export-all >x && \ rm pubring.gpg && gpg --import x Only v4 keys (i.e not the old RSA keys) benefit from this caching. * New translations: Estonian, Turkish. Noteworthy changes in version 1.0.4 (2000-10-17) ------------------------------------------------ * Fixed a serious bug which could lead to false signature verification results when more than one signature is fed to gpg. This is the primary reason for releasing this version. * New utility gpgv which is a stripped down version of gpg to be used to verify signatures against a list of trusted keys. * Rijndael (AES) is now supported and listed with top preference. * --with-colons now works with --print-md[s]. Noteworthy changes in version 1.0.3 (2000-09-18) ------------------------------------------------ * Fixed problems with piping to/from other MS-Windows software * Expiration time of the primary key can be changed again. * Revoked user IDs are now marked in the output of --list-key * New options --show-session-key and --override-session-key to help the British folks to somewhat minimize the danger of this Orwellian RIP bill. * New options --merge-only and --try-all-secrets. * New configuration option --with-egd-socket. * The --trusted-key option is back after it left us with 0.9.5 * RSA is supported. Key generation does not yet work but will come soon. * CAST5 and SHA-1 are now the default algorithms to protect the key and for symmetric-only encryption. This should solve a couple of compatibility problems because the old algorithms are optional according to RFC2440 * Twofish and MDC enhanced encryption is now used. PGP 7 supports this. Older versions of GnuPG don't support it, so they should be upgraded to at least 1.0.2 Noteworthy changes in version 1.0.2 (2000-07-12) ---------------------------------------------- * Fixed expiration handling of encryption keys. * Add an experimental feature to do unattended key generation. * The user is now asked for the reason of revocation as required by the new OpenPGP draft. * There is a ~/.gnupg/random_seed file now which saves the state of the internal RNG and increases system performance somewhat. This way the full entropy source is only used in cases were it is really required. Use the option --no-random-seed-file to disable this feature. * New options --ignore-time-conflict and --lock-never. * Some fixes for the W32 version. * The entropy.dll is not anymore used by the W32 version but replaced by code derived from Cryptlib. * Encryption is now much faster: About 2 times for 1k bit keys and 8 times for 4k keys. * New encryption keys are generated in a way which allows a much faster decryption. * New command --export-secret-subkeys which outputs the the _primary_ key with it's secret parts deleted. This is useful for automated decryption/signature creation as it allows to keep the real secret primary key offline and thereby protecting the key certificates and allowing to create revocations for the subkeys. See the FAQ for a procedure to install such secret keys. * Keygeneration now writes to the first writeable keyring or as default to the one in the homedirectory. Prior versions ignored all --keyring options. * New option --command-fd to take user input from a file descriptor; to be used with --status-fd by software which uses GnuPG as a backend. * There is a new status PROGRESS which is used to show progress during key generation. * Support for the new MDC encryption packets. To create them either --force-mdc must be use or cipher algorithm with a blocksize other than 64 bits is to be used. --openpgp currently disables MDC packets entirely. This option should not yet be used. * New option --no-auto-key-retrieve to disable retrieving of a missing public key from a keyserver, when a keyserver has been set. * Danish translation Noteworthy changes in version 1.0.1 (1999-12-16) ----------------------------------- * New command --verify-files. New option --fast-list-mode. * $http_proxy is now used when --honor-http-proxy is set. * Fixed some minor bugs and the problem with conventional encrypted packets which did use the gpg v3 partial length headers. * Add Indonesian and Portugese translations. * Fixed a bug with symmetric-only encryption using the non-default 3DES. The option --emulate-3des-s2k-bug may be used to decrypt documents which have been encrypted this way; this should be done immediately as this workaround will be remove in 1.1 * Can now handle (but not display) PGP's photo IDs. I don't know the format of that packet but after stripping a few bytes from the start it looks like a JPEG (at least my test data). Handling of this package is required because otherwise it would mix up the self signatures and you can't import those keys. * Passing non-ascii user IDs on the commandline should now work in all cases. * New keys are now generated with an additional preference to Blowfish. * Removed the GNU Privacy Handbook from the distribution as it will go into a separate one. Noteworthy changes in version 1.0.0 (1999-09-07) ----------------------------------- * Add a very preliminary version of the GNU Privacy Handbook to the distribution (lynx doc/gph/index.html). * Changed the version number to GnuPG 2001 ;-) Noteworthy changes in version 0.9.11 (1999-09-03) ------------------------------------ * UTF-8 strings are now correctly printed (if --charset is set correctly). Output of --with-colons remains C-style escaped UTF-8. * Workaround for a problem with PGP 5 detached signature in textmode. * Fixed a problem when importing new subkeys (duplicated signatures). Noteworthy changes in version 0.9.10 (1999-07-23) ------------------------------------ * Some strange new options to help pgpgpg * Cleaned up the dox a bit. Noteworthy changes in version 0.9.9 ----------------------------------- * New options --[no-]utf8-strings. * New edit-menu commands "enable" and "disable" for entire keys. * You will be asked for a filename if gpg cannot deduce one. * Changes to support libtool which is needed for the development of libgcrypt. * New script tools/lspgpot to help transferring assigned trustvalues from PGP to GnuPG. * New commands --lsign-key and made --sign-key a shortcut for --edit and sign. * New options (#122--126 ;-) --[no-]default-recipient[-self], --disable-{cipher,pubkey}-algo. See the man page. * Enhanced info output in case of multiple recipients and fixed exit code. * New option --allow-non-selfsigned-uid to work around a problem with the German IN way of separating signing and encryption keys. Noteworthy changes in version 0.9.8 (1999-06-26) ----------------------------------- * New subcommand "delsig" in the edit menu. * The name of the output file is not anymore the one which is embedded in the processed message, but the used filename with the extension stripped. To revert to the old behaviour you can use the option --use-embedded-filename. * Another hack to cope with pgp2 generated detached signatures. * latin-2 character set works (--charset=iso-8859-2). * New option --with-key-data to list the public key parameters. New option -N to insert notations and a --set-policy-url. A couple of other options to allow reseting of options. * Better support for HPUX. Noteworthy changes in version 0.9.7 (1999-05-23) ----------------------------------- * Add some work arounds for a bugs in pgp 2 which led to bad signatures when used with canonical texts in some cases. * Enhanced some status outputs. Noteworthy changes in version 0.9.6 (1999-05-06) ----------------------------------- * Twofish is now statically linked by default. The experimental 128 bit version is now disabled. Full support will be available as soon as the OpenPGP WG has decided on an interpretation of rfc2440. * Dropped support for the ancient Blowfish160 which is not OpenPGP. * Merged gpgm and gpg into one binary. * Add "revsig" and "revkey" commands to the edit menu. It is now possible to revoke signature and subkeys. Noteworthy changes in version 0.9.5 (1999-03-20) ----------------------------------- * New command "lsign" in the keyedit menu to create non-exportable signatures. Removed --trusted-keys option. * A bunch of changes to the key validation code. * --list-trust-path now has an optional --with-colons format. * New command --recv-keys to import keys from an keyserver. Noteworthy changes in version 0.9.4 (1999-03-08) ----------------------------------- * New configure option --enable-static-rnd=[egd|linux|unix|none] to select a random gathering module for static linking. * The original text is now verbatim copied to a cleartext signed message. * Bugfixes but there are still a couple of bugs. Noteworthy changes in version 0.9.3 (1999-02-19) ----------------------------------- * Changed the internal design of getkey which now allows a efficient lookup of multiple keys and add a word match mode. * New options --[no-]encrypt-to. * Some changes to the configure stuff. Switched to automake 1.4. Removed intl/ from CVS, autogen.sh now uses gettextize. * Preferences now include Twofish. Removed preference to Blowfish with a special hack to suppress the "not listed in preferences" warning; this is to allow us to switch completely to Twofish in the near future. * Changed the locking stuff. * Print all user ids of a good signature. Noteworthy changes in version 0.9.2 (1999-01-01) ----------------------------------- * add some additional time warp checks. * Option --keyserver and command --send-keys to utilize HKP servers. * Upgraded to zlib 1.1.3 and fixed an inflate bug * More cleanup on the cleartext signatures. Noteworthy changes in version 0.9.1 (1999-01-01) ----------------------------------- * Polish language support. * When querying the passphrase, the key ID of the primary key is displayed along with the one of the used secondary key. * Fixed a bug occurring when decrypting pgp 5 encrypted messages, fixed an infinite loop bug in the 3DES code and in the code which looks for trusted signatures. * Fixed a bug in the mpi library which caused signatures not to compare okay. * Rewrote the handling of cleartext signatures; the code is now better maintainable (I hope so). * New status output VALIDSIG only for valid signatures together with the fingerprint of the signer's key. Noteworthy changes in version 0.9.0 (1998-12-23) ----------------------------------- * --export does now only exports rfc2440 compatible keys; the old behaviour is available with --export-all. Generation of v3 ElGamal (sign and encrypt) keys is not longer supported. * Fixed the uncompress bug. * Rewrote the rndunix module. There are two environment variables used for debugging now: GNUPG_RNDUNIX_DBG give the file to write debugging information (use "-" for stdout) and if GNUPG_RNDUNIX_DBGALL is set, all programs which are only tried are also printed. * New option --escape-from-lines to "dash-escape" "From " lines to prevent mailers to change them to ">From ". This is not enabled by default because it is not in compliance with rfc2440 - however, you should turn it on. Noteworthy changes in version 0.4.5 (1998-12-08) ----------------------------------- * The keyrings and the trustdb is now locked, so that other GnuPG processes won't damage these files. You may want to put the option --lock-once into your options file. * The latest self-signatures are now used; this enables --import to see updated preferences etc. * Import of subkeys should now work. * Random gathering modules may now be loaded as extensions. Add such a module for most Unices but it is very experimental! * Brazilian language support. Noteworthy changes in version 0.4.4 (1998-11-20) ----------------------------------- * Fixed the way the key expiration time is stored. If you have an expiration time on your key you should fix it with --edit-key and the command "expire". I apologize for this inconvenience. * Add option --charset to support "koi8-r" encoding of user ids. (Not yet tested). * Preferences should now work again. You should run "gpgm --check-trustdb \*" to rebuild all preferences. * Checking of certificates should now work but this needs a lot of testing. Key validation values are now cached in the trustdb; they should be recalculated as needed, but you may use --check-trustdb or --update-trustdb to do this. * Spanish translation by Urko Lusa. * Patch files are from now on signed. See the man page for the new option --not-dash-escaped. * New syntax: --edit-key [] If you run it without --batch the commands are executed and then you are put into normal mode unless you use "quit" or "save" as one of the commands. When in batch mode, the program quits after the last command, so you have to use "save" if you did some changes. It does not yet work completely, but may be used to list so the keys etc. Noteworthy changes in version 0.4.3 (1998-11-08) ----------------------------------- * 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:". 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) * commandline option processing now works as expected for GNU programs with the exception that you can't mix options and normal arguments. * Now --list-key lists all matching keys. This is needed in some other places too. Noteworthy changes in version 0.4.2 (1998-10-18) ----------------------------------- * 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 accidentally 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 (1998-10-07) ----------------------------------- * 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 (1998-09-18) ----------------------------------- * 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 yyyy-mm-dd format are now printed in local time. Noteworthy changes in version 0.3.5 (1998-09-14) ----------------------------------- * 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 available 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 (1998-08-11) ----------------------------------- * New options --comment and --set-filename; see g10/OPTIONS * yes/no, y/n localized. * Fixed some bugs. Noteworthy changes in version 0.3.3 (1998-08-08) ----------------------------------- * 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 specify 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/trustdb.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 password 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 for various 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 implementation. 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 (1998-07-09) ----------------------------------- * 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 implicitly added as the very first one unless --no-default-keyring is used. * Fixed setuid and dlopen bug. Noteworthy changes in version 0.3.1 (1998-07-06) ----------------------------------- * 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 (1998-06-25) ----------------------------------- * 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 library. * Support for dynamic loading of new algorithms. * Moved tiger to an extension module. Noteworthy changes in version 0.2.19 (1998-05-29) ------------------------------------ * 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 (1998-05-15) ------------------------------------ * 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 (1998-05-04) ------------------------------------ * 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 (1998-04-28) ------------------------------------ * Add experimental support for the TIGER/192 message digest 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 (1998-04-09) ------------------------------------ * 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 (1998-04-02) ------------------------------------ * Changed the internal handling of keyrings. * Add support to list PGP 5 keyrings with subkeys * 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 (1998-03-10) ------------------------------------ * Verify of DSA signatures works. * Re-implemented the slower random number generator. Noteworthy changes in version 0.2.12 (1998-03-07) ------------------------------------ * --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 (1998-03-02) ------------------------------------ * 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, next time the secret key is used? Noteworthy changes in version 0.2.10 (1998-02-27) ------------------------------------ * 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 everything 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 (1998-02-26) ----------------------------------- * Fixed FreeBSD bug. * Added a simple man page. * Switched to automake1.2f and a newer gettext. Noteworthy changes in version 0.2.8 (1998-02-24) ----------------------------------- * 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 (1998-02-18) ----------------------------------- * 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 (1998-02-13) ----------------------------------- * Option "--export" works. Noteworthy changes in version 0.2.5 (1998-02-12) ----------------------------------- * 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 (1998-02-11) ----------------------------------- * nearly doubled the speed of the ElGamal signature verification. * backup copies of keyrings are created. * assembler stuff for Pentium; gives about 15% better performance. * fixed a lot of bugs. Noteworthy changes in version 0.2.3 (1998-02-09) ----------------------------------- * 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 memory 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.
