See . [CVE-2013-4576] * Put only the major version number by default into armored output. * Do not create a trustdb file if --trust-model=always is used. * Print the keyid for key packets with --list-packets. * Changed modular exponentiation algorithm to recover from a small performance loss due to a change in 1.4.14. Noteworthy changes in version 1.4.15 (2013-10-04) ------------------------------------------------- * Fixed possible infinite recursion in the compressed packet parser. [CVE-2013-4402] * Protect against rogue keyservers sending secret keys. * Use 2048 bit also as default for batch key generation. * Minor bug fixes. Noteworthy changes in version 1.4.14 (2013-07-25) ------------------------------------------------- * Mitigate the Yarom/Falkner flush+reload side-channel attack on RSA secret keys. See . [CVE-2013-4242] * Fixed IDEA for big-endian CPUs * Improved the diagnostics for failed keyserver lockups. * Minor bug and portability fixes. Noteworthy changes in version 1.4.13 (2012-12-20) ------------------------------------------------- * Add support for the old cipher algorithm IDEA. * Minor bug fixes. Noteworthy changes in version 1.4.12 (2012-01-30) ------------------------------------------------- * GPG now accepts a space separated fingerprint as a user ID. This allows to copy and paste the fingerprint from the key listing. * Removed support for the original HKP keyserver which is not anymore used by any site. * Rebuild the trustdb after changing the option --min-cert-level. * Improved JPEG detection. * Included more VMS patches * Made it easier to create an installer for Windows. * Supports the 32 bit variant of the mingw-w64 toolchain. * Made file locking more portable. * Minor bug fixes. Noteworthy changes in version 1.4.11 (2010-10-18) ------------------------------------------------- * Bug fixes and portability changes. * Minor changes for better interoperability with GnuPG-2. Noteworthy changes in version 1.4.10 (2009-09-02) ------------------------------------------------- * 2048 bit RSA keys are now generated by default. The default hash algorithm preferences has changed to prefer SHA-256 over SHA-1. 2048 bit DSA keys are now generated to use a 256 bit hash algorithm * Support v2 OpenPGP cards. * The algorithm to compute the SIG_ID status has been changed to match the one from 2.0.10. * Improved file locking. Implemented it for W32. * Fixed a memory leak which made imports of many keys very slow. * Many smaller bug fixes. * Support for the Camellia cipher (RFC-5581). * Support for HKP keyservers over SSL ("HKPS"). Noteworthy changes in version 1.4.9 (2008-03-26) ------------------------------------------------ * Improved AES encryption performance by more than 20% (on ia32). Decryption is also a bit faster. * Fixed possible memory corruption bug in 1.4.8 while importing OpenPGP keys. [CVE-2008-1530] Noteworthy changes in version 1.4.8 (2007-12-20) ------------------------------------------------ ******************************************* * A decade of GnuPG: g10-0.0.0.tar.gz was * * released exactly 10 years ago. * ******************************************* * Changed the license to GPLv3. * Improved detection of keyrings specified multiple times. * Changes to better cope with broken keyservers. * Minor bug fixes. * The new OpenPGP standard is now complete, and has been published as RFC-4880. The GnuPG --openpgp mode (note this is not the default) has been updated to match the new standard. The --rfc2440 option can be used to return to the older RFC-2440 behavior. The main differences between the two are "--enable-dsa2 --no-rfc2440-text --escape-from-lines --require-cross-certification". * By default (i.e. --gnupg mode), --require-cross-certification is now on. --rfc2440-text and --force-v3-sigs are now off. * Allow encryption using legacy Elgamal sign+encrypt keys if option --rfc2440 is used. * Fixed the auto creation of the key stub for smartcards. * Fixed a rare bug in decryption using the OpenPGP card. * Fix RFC-4880 typo in the SHA-224 hash prefix. Old SHA-224 signatures will continue to work. Noteworthy changes in version 1.4.7 (2007-03-05) ------------------------------------------------ * 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]. * [W32] The environment variable LANGUAGE may be used to override the language given by HKCU\Software\GNU\GnuPG:Lang. The language files "*.mo" are expected in a directory named "gnupg.nls" below the directory with the gpg.exe binary. * New --verify-option show-primary-uid-only. Noteworthy changes in version 1.4.6 (2006-12-06) ------------------------------------------------ * Fixed a serious and exploitable bug in processing encrypted packages. [CVE-2006-6235]. * Fixed a buffer overflow in gpg. [bug#728, CVE-2006-6169] * Fixed a bug while decrypting certain compressed and encrypted messages. [bug#537] * Added --s2k-count to set the number of times passphrase mangling is repeated. The default is 65536 times. * 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. * Added a GPL license exception to the keyserver helper programs gpgkeys_ldap, gpgkeys_curl, and gpgkeys_hkp, to clarify any potential questions about the ability to distribute binaries that link to the OpenSSL library. GnuPG does not link directly to OpenSSL, but libcurl (used for HKP, HTTP, and FTP) and OpenLDAP (used for LDAP) may. Note that this license exception is considered a bug fix and is intended to forgive any violations pertaining to this issue, including those that may have occurred in the past. * Man pages are now built from the same source as those of GnuPG-2. Noteworthy changes in version 1.4.5 (2006-08-01) ------------------------------------------------ * Reverted check for valid standard handles under Windows. * More DSA2 tweaks. * Fixed a problem uploading certain keys to the smart card. * Fixed 2 more possible memory allocation attacks. * Added Norwegian translation. Noteworthy changes in version 1.4.4 (2006-06-25) ------------------------------------------------ * User IDs are now capped at 2048 bytes. This avoids a memory allocation attack (see CVE-2006-3082). * Added support for the SHA-224 hash. Like the SHA-384 hash, it is mainly useful when DSS (the US Digital Signature Standard) compatibility is desired. * Added support for the latest update to DSA keys and signatures. This allows for larger keys than 1024 bits and hashes other than SHA-1 and RIPEMD/160. Note that not all OpenPGP implementations can handle these new keys and signatures yet. See "--enable-dsa2" in the manual for more information. Noteworthy changes in version 1.4.3 (2006-04-03) ------------------------------------------------ * If available, cURL-based keyserver helpers are built that can retrieve keys using HKP or any protocol that cURL supports (HTTP, HTTPS, FTP, FTPS, etc). If cURL is not available, HKP and HTTP are still supported using a built-in cURL emulator. To force building the old pre-cURL keyserver helpers, use the configure option --enable-old-keyserver-helpers. Note that none of this affects finger or LDAP support, which are unchanged. Note also that a future version of GnuPG will remove the old keyserver helpers altogether. * Implemented Public Key Association (PKA) signature verification. This uses special DNS records and notation data to associate a mail address with an OpenPGP key to prove that mail coming from that address is legitimate without the need for a full trust path to the signing key. * When exporting subkeys, those specified with a key ID or fingerpint and the '!' suffix are now merged into one keyblock. * Added "gpg-zip", a program to create encrypted archives that can interoperate with PGP Zip. * Added support for signing subkey cross-certification "back signatures". Requiring cross-certification to be present is currently off by default, but will be changed to on by default in the future, once more keys use it. A new "cross-certify" command in the --edit-key menu can be used to update signing subkeys to have cross-certification. * The key cleaning options for --import-options and --export-options have been further polished. "import-clean" and "export-clean" replace the older import-clean-sigs/import-clean-uids and export-clean-sigs/export-clean-uids option pairs. * New "minimize" command in the --edit-key menu removes everything that can be removed from a key, rendering it as small as possible. There are corresponding "export-minimal" and "import-minimal" commands for --export-options and --import-options. * New --fetch-keys command to retrieve keys by specifying a URI. This allows direct key retrieval from a web page or other location that can be specified in a URI. Available protocols are HTTP and finger, plus anything that cURL supplies, if built with cURL support. * Files containing several signed messages are not allowed any longer as there is no clean way to report the status of such files back to the caller. To partly revert to the old behaviour the new option --allow-multisig-verification may be used. * The keyserver helpers can now handle keys in either ASCII armor or binary format. * New auto-key-locate option that takes an ordered list of methods to locate a key if it is not available at encryption time (-r or --recipient). Possible methods include "cert" (use DNS CERT as per RFC2538bis, "pka" (use DNS PKA), "ldap" (consult the LDAP server for the domain in question), "keyserver" (use the currently defined keyserver), as well as arbitrary keyserver URIs that will be contacted for the key. * Able to retrieve keys using DNS CERT records as per RFC-4398. Noteworthy changes in version 1.4.2 (2005-07-26) ------------------------------------------------ * New command "verify" in the card-edit menu to display the Private-DO-3. The Admin command has been enhanced to take the optional arguments "on", "off" and "verify". The latter may be used to verify the Admin Pin without modifying data; this allows displaying the Private-DO-4 with the "list" command. * Rewrote large parts of the card code to optionally make use of a running gpg-agent. If --use-agent is being used and a gpg-agent with enabled scdaemon is active, gpg will now divert all card operations to that daemon. This is required because both, scdaemon and gpg require exclusive access to the card reader. By delegating the work to scdaemon, both can peacefully coexist and scdaemon is able to control the use of the reader. Note that this requires at least gnupg 1.9.17. * Fixed a couple of problems with the card reader. * Command completion is now available in the --edit-key and --card-edit menus. Filename completion is available at all filename prompts. Note that completion is only available if the system provides a readline library. * New experimental HKP keyserver helper that uses the cURL library. It is enabled via the configure option --with-libcurl like the other (also experimental) cURL helpers. * New key cleaning options that can be used to remove unusable (expired, revoked) signatures from a key. This is available via the new "clean" command in --edit-key on a key by key basis, as well as via the import-clean-sigs/import-clean-uids and export-clean-sigs/export-clean-uids options for --import-options and --export-options. These are currently off by default, and replace the import-unusable-sigs/export-unusable-sigs options from version 1.4.1. * New export option export-reset-subkey-passwd. * New option --limit-card-insert-tries. Noteworthy changes in version 1.4.1 (2005-03-15) ------------------------------------------------ * New --rfc2440-text option which controls how text is handled in signatures. This is in response to some problems seen with certain PGP/MIME mail clients and GnuPG version 1.4.0. More details about this are available at . * New "import-unusable-sigs" and "export-unusable-sigs" tags for --import-options and --export-options. These are off by default, which causes GnuPG to not import or export key signatures that are not usable (e.g. expired signatures). * New experimental HTTP, HTTPS, FTP, and FTPS keyserver helper that uses the cURL library to retrieve keys. This is disabled by default, but may be enabled with the configure option --with-libcurl. Without this option, the existing HTTP code is used for HTTP, and HTTPS, FTP, and FTPS are not supported. * When running a --card-status or --card-edit and a public key is available, missing secret key stubs will be created on the fly. Details of the key are listed too. * The implicit packet dumping in double verbose mode is now sent to stderr and not to stdout. * Added countermeasures against the Mister/Zuccherato CFB attack . * [W32] The algorithm for the default home directory changed: First we look at the environment variable GNUPGHOME, if this one is not set, we check whether the registry entry {HKCU,HKLM}\Software\GNU\GnuPG:HomeDir has been set. If this fails we use a GnuPG directory below the standard application data directory (APPDATA) of the current user. Only in the case that this directory cannot be determined, the old default of c:\gnupg will be used. The option --homedir still overrides all of them. * [W32] The locale selection under Windows changed. You need to enter the locale in the registry at HKCU\Software\GNU\GnuPG:Lang. For German you would use "de". If it is not set, GnuPG falls back to HKLM. The languages files "*.mo" are expected in a directory named "gnupg.nls" below the installation directory; that directory must be stored in the registry at the same key as above with the name "Install Directory". * Add new --edit-key command "bkuptocard" to allow restoring a card key from a backup. * The "fetch" command of --card-edit now retrieves the key using the default keyserver if no URL has been stored on the card. * New configure option --enable-noexecstack. Noteworthy changes in version 1.4.0 (2004-12-16) ------------------------------------------------ * See the file doc/highlights-1.4.txt for an overview of all changes in respect to the 1.2 series. Noteworthy changes in version 1.3.93 (2004-12-14) ------------------------------------------------- * Ask the user to repeat a changed PIN. * Switched to automake 1.9. Minor big fixes. Noteworthy changes in version 1.3.92 (2004-10-28) ------------------------------------------------- * Added Russian man page. Thanks to Pawel I. Shajdo. * libiconv is now used to support other character sets other than UTF-8, Latin-1,-2 and KOI8-2. The W32 version will only work correctly when iconv.dll is installed on the system. A binary version is available at all GNU mirror sites under libiconv. * gettext for Windows has been simplified. The MO files are now distributed UTF-8 encoded and gpg translates on the fly. Noteworthy changes in version 1.3.91 (2004-10-15) ------------------------------------------------- * A new configure option --enable-selinux-support disallows processing of confidential files used by gpg (e.g. secring.gpg). This helps writing ACLs for the SELinux kernel. * Support for fetching keys via finger has been added. This is useful for setting a preferred keyserver URL like "finger:wk@g10code.com". * Timeout support has been added to the keyserver helpers. This allows users to set an upper limit on how long to wait for the keyserver before giving up. * New "direct" trust model where users can set key validity directly if they do not want to participate in the web of trust. * Minor bug fixes, code and string cleanups. Noteworthy changes in version 1.3.90 (2004-10-01) ------------------------------------------------- * Readline support at all prompts is now available if the system provides a readline library. The build time option --without-readline may be used to disable this feature. * Support for the OpenPGP smartcard is now enabled by default. Use the option --disable-card-support to build without support for smartcards. * New command "addcardkey" in the key edit menu to add subkeys to a smartcard. New command "keytocard" to transfer a key to a smartcard. The serial number of the card is show in secret key listings. * -K may now be used as an alias for --list-secret-keys. * HTTP Basic authentication is now supported for all HKP and HTTP keyserver functions, either through a proxy or via direct access. Noteworthy changes in version 1.3.6 (2004-05-22) ------------------------------------------------ * New --keyid-format option that selects short (99242560), long (DB698D7199242560), 0xshort (0x99242560), or 0xlong (0xDB698D7199242560) keyid displays. This lets users tune the display to what they prefer. * The --list-options and --verify-options option "show-long-keyids" has been removed since --keyid-format obviates the need for them. * Support for the old quasi-1991 partial length encoding has been removed. * The --export-all and --export-options include-non-rfc options have been removed as superfluous since nonstandard V3 Elgamal sign+encrypt keys have been removed. * Preferred keyserver support has been added. Users may set a preferred keyserver via the --edit-key command "keyserver". If the --keyserver-option honor-keyserver-url is set (and it is by default), then the preferred keyserver is used when refreshing that key. * The --sig-keyserver-url option can be used to inform signature recipients where the signing key can be downloaded. When verifying the signature, if the signing key is not present, and the keyserver options honor-keyserver-url and auto-key-retrieve are set, this URL will be used to retrieve the key. * Support for fetching keys via HTTP has been added. This is mainly useful for setting a preferred keyserver URL like "http://www.jabberwocky.com/key.asc". * New --ask-cert-level/--no-ask-cert-level option to turn on and off the prompt for signature level when signing a key. Defaults to off. * New --gpgconf-list command for internal use by the gpgconf utility from gnupg 1.9.x. Noteworthy changes in version 1.3.5 (2004-02-26) ------------------------------------------------ * New --min-cert-level option to disregard key signatures that are under a specified level. Defaults to 2 (i.e. discard 0x11 signatures). * New --max-output option to limit the amount of plaintext output generated by GnuPG. This option can be used by programs which call GnuPG to process messages that may result in plaintext larger than the calling program is prepared to handle. This is sometimes called a "Decompression Bomb". * New --list-config command for frontends and other programs that call GnuPG. See doc/DETAILS for the specifics of this. * Some performance improvements with large keyrings. See the build time option --enable-key-cache=SIZE in the README file for details. * Some portability fixes for the OpenBSD/i386, HPPA, and AIX platforms. * New keyserver-option "http-proxy" to specify which proxy to use in the config file without using environment variables. * Added support for storing, retrieving, and searching for keys in LDAP servers. Note that this is different than the "LDAP keyserver" which was already (and remains) supported. * Added support for TLS and LDAPS session encryption for LDAP. * --show-session-key/--override-session-key now works with --symmetric messages. * The configure options --enable-rsa and --disable-rsa can now be used to enable or disable the RSA algorithm. This can be useful for embedded use where space is tight. --enable-minimal includes --disable-rsa. RSA is enabled by default. * The last support for Elgamal sign+encrypt keys has been removed. Noteworthy changes in version 1.3.4 (2003-11-27) ------------------------------------------------ * Added support for BZIP2 compression. This should be considered experimental, and is only available if the libbzip2 library is installed. * Added the ability to handle messages that can be decrypted with either a passphrase or a secret key. These messages may be generated with --symmetric --encrypt or --symmetric --sign --encrypt. * The config file search has been enhanced to try for less specific filename matches before giving up. For example, version 1.3.4 will try for gpg.conf-1.3.4, gpg.conf-1.3, and gpg.conf-1 before falling back to the regular gpg.conf file. * Fixed a format string bug in the HKP keyserver handler. * Support for Elgamal sign+encrypt keys has been removed. Old signatures may still be verified, and existing encrypted messages may still be decrypted, but no new signatures may be issued by, and no new messages will be encrypted to, these keys. Noteworthy changes in version 1.3.3 (2003-10-10) ------------------------------------------------ * Basic support for the OpenPGP card. New commands --card-status, --card-edit, --change-pin and the configuration options --reader-port, --ctapi-driver, --pcsc-driver, and --disable-ccid. * Full (read/write) support for the SHA-256 hash has been added. * Support for the TIGER/192 hash has been dropped. This should not be interpreted as a statement as to the strength of TIGER/192 - rather, the upcoming revision to the OpenPGP standard removes support for several unused (or mostly unused) hashes. * Revoked or expired user IDs are now skipped when selecting keys for encryption. Specifying a key by the key ID overrides this check and allows the selection of any key. * Note that --no-mangle-dos-filenames is now the default. If you are upgrading from a 1.2.x version of GnuPG, and are running a very old version of Windows that has the 8.3 filename limit, you may need to change this. * Multiple "Comment:" lines in armored output are now allowed. * New --list-options option. This option takes a list of arguments that allows the user to customize exactly what key listings (including the --edit-key listing) look like, enabling or disabling things such as photo display, policy URL, preferred keyserver URL, or notation display, long or short keyIDs, calculated validity for each user ID, etc. See the manual for the complete list of list-options. * New --verify-options option. This option takes a list of arguments that allows the user to customize exactly what happens during signature verification, enabling or disabling things such as photo display, policy URL, preferred keyserver URL, or notation display, long or short keyIDs, calculated validity for each user ID, etc. See the manual for the complete list of verify-options. * New --sig-keyserver-url to embed a "where to get my key" subpacket into a signature. * The options --show-photos, --show-policy-url, --show-notation, and --show-keyring are all deprecated in favor of those arguments to --list-options and --verify-options. The new method is more flexible since a user can specify (for example) showing photos during sig verification, but not in key listings. * The complete fingerprint of the key that made a given key certification is now available in the --with-colons output. For technical reasons, this is only available when running with --no-sig-cache set. See doc/DETAILS for the specifics of this. * IPv6 support for HKP keyserver access. IPv6 for LDAP keyserver access is also supported, but is dependent on the LDAP library used. * To simplify running both the stable (1.2.x) and development (1.3.x) versions of GnuPG, the development version will try to load the options file gpg.conf-VERSION (e.g. gpg.conf-1.3.3 for this release) before falling back to the regular gpg.conf file. * Two new %-expandos for use in notation and policy URLs. "%g" expands to the fingerprint of the key making the signature (which might be a subkey), and "%p" expands to the fingerprint of the primary key that owns the key making the signature. * New "tru" record in --with-colons --list-keys listings. It shows the status of the trust database that was used to calculate the key validity in the listings. See doc/DETAILS for the specifics of this. * New REVKEYSIG status tag for --status-fd. It indicates a valid signature that was issued by a revoked key. See doc/DETAILS for the specifics of this. * A number of portability changes to make building GnuPG on less-common platforms easier. 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. 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 ------------------------------------ * 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 ------------------------------------ * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * --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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 ----------------------------------- * 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 accidently 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 yyyy-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 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 ----------------------------------- * 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 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 ----------------------------------- * 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 ----------------------------------- * 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 library. * 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 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 ------------------------------------ * 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 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 ------------------------------------ * 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, next 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 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 ----------------------------------- * 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 performance. * 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 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.
