     the forthcoming GnuPG 2.2.4.


Noteworthy changes in version 1.8.1 (2017-08-27)  [C22/A2/R1]
------------------------------------------------

 * Bug fixes:

   - Mitigate a local side-channel attack on Curve25519 dubbed "May
     the Fourth be With You".  [CVE-2017-0379] [also in 1.7.9]

   - Fix build problems with the Jitter RNG

   - Fix assembler code build problems on Rasbian (ARMv8/AArch32-CE).


Noteworthy changes in version 1.8.0 (2017-07-18)  [C22/A2/R0]
------------------------------------------------

 * New interfaces:

   - New cipher mode XTS

   - New hash function Blake-2

   - New function gcry_mpi_point_copy.

   - New function gcry_get_config.

   - GCRYCTL_REINIT_SYSCALL_CLAMP allows to init nPth after Libgcrypt.

   - New global configuration file /etc/gcrypt/random.conf.

 * Extended interfaces:

   - GCRYCTL_PRINT_CONFIG does now also print build information for
     libgpg-error and the used compiler version.

   - GCRY_CIPHER_MODE_CFB8 is now supported.

   - Add Stribog OIDs.  [also in 1.7.4]

 * Performance:

   - A jitter based entropy collector is now used in addition to the
     other entropy collectors.

   - Optimized gcry_md_hash_buffers for SHA-256 and SHA-512.

   - More ARMv8/AArch32 improvements for AES, GCM, SHA-256, and SHA-1.
     [also in 1.7.4]

   - Add ARMv8/AArch32 assembly implementation for Twofish and
     Camellia.  [also in 1.7.4]

   - Add bulk processing implementation for ARMv8/AArch32.
     [also in 1.7.4]

   - Improve the DRBG performance and sync the code with the Linux
     version.  [also in 1.7.4]

 * Internal changes:

   - Libgpg-error 1.25 is now required.  This avoids stalling of nPth
     threads due to contention on internal Libgcrypt locks (e.g. the
     random pool lock).

   - The system call clamp of libgpg-error is now used to wrap the
     blocking read of /dev/random.  This allows other nPth threads to
     run while Libgcrypt is gathering entropy.

   - When secure memory is requested by the MPI functions or by
     gcry_xmalloc_secure, they do not anymore lead to a fatal error if
     the secure memory pool is used up.  Instead new pools are
     allocated as needed.  These new pools are not protected against
     being swapped out (mlock can't be used).  However, these days
     this is considered a minor issue and can easily be mitigated by
     using encrypted swap space.  [also in 1.7.4]

 * Bug fixes:

   - Fix AES CTR self-check detected failure in the SSSE3 based
     implementation.  [also in 1.7.6]

   - Remove gratuitous select before the getrandom syscall.
     [also in 1.7.6]

   - Fix regression in mlock detection.  [bug#2870] [also in 1.7.5]

   - Fix GOST 28147 CryptoPro-B S-box.   [also in 1.7.4]

   - Fix error code handling of mlock calls.  [also in 1.7.4]

   - Fix possible timing attack on EdDSA session key. [also in 1.7.7]

   - Fix long standing bug in secure memory implementation which could
     lead to a segv on free. [bug#3027] [also in 1.7.7]

   - Mitigate a flush+reload side-channel attack on RSA secret keys
     dubbed "Sliding right into disaster".  For details see
     <https://eprint.iacr.org/2017/627>.  [CVE-2017-7526] [also in 1.7.8]

Noteworthy changes in version 1.6.0 (2013-12-16) [C20/A0/R0]
------------------------------------------------

 * Removed the long deprecated gcry_ac interface.  Thus Libgcrypt is
   not anymore ABI compatible to previous versions if they used the ac
   interface.

 * Removed the module register subsystem.

 * The deprecated message digest debug macros have been removed.  Use
   gcry_md_debug instead.

 * Removed deprecated control codes.

 * Improved performance of most cipher algorithms as well as for the
   SHA family of hash functions.

 * Added support for the IDEA cipher algorithm.

 * Added support for the Salsa20 and reduced Salsa20/12 stream ciphers.

 * Added limited support for the GOST 28147-89 cipher algorithm.

 * Added support for the GOST R 34.11-94 and R 34.11-2012 (Stribog)
   hash algorithms.

 * Added a random number generator to directly use the system's RNG.
   Also added an interface to prefer the use of a specified RNG.

 * Added support for the SCRYPT algorithm.

 * Mitigated the Yarom/Falkner flush+reload side-channel attack on RSA
   secret keys.  See <http://eprint.iacr.org/2013/448> [CVE-2013-4242].

   deprecated.  Use GCRY_PK_ECC if you need an algorithm id.

 * Changed gcry_pk_genkey for "ecc" to only include the curve name and
   not the parameters.  The flag "param" may be used to revert this.

 * Added a feature to globally disable selected hardware features.

   is not flexible enough and would always require ABI changes to
   extend the internal interfaces.  It will eventually be removed.
   Please contact us on the gcrypt-devel mailing list to discuss
   whether you really need this feature or how it can be replaced by
   an internal plugin mechanism.

Noteworthy changes in version 1.4.4 (2009-01-22)
------------------------------------------------

 * Publish GCRY_MODULE_ID_USER and GCRY_MODULE_ID_USER_LAST constants.
   This functionality has been in Libgcrypt since 1.3.0.

 * MD5 may now be used in non-enforced fips mode.

 * Fixed HMAC for SHA-384 and SHA-512 with keys longer than 64 bytes.

 * In fips mode, RSA keys are now generated using the X9.31 algorithm
   and DSA keys using the FIPS 186-2 algorithm.

 * The transient-key flag is now also supported for DSA key
   generation.  DSA domain parameters may be given as well.


Noteworthy changes in version 1.4.3 (2008-09-18)
------------------------------------------------

 * Try to auto-initialize Libgcrypt to minimize the effect of
   applications not doing that correctly.  This is not a perfect
   solution but given that many applicationion would totally fail
   without such a hack, we try to help at least with the most common
   cases.  Folks, please read the manual to learn how to properly
   initialize Libgcrypt!

 * Auto-initialize the secure memory to 32k instead of aborting the
   process.

 * Log fatal errors via syslog.

 * Changed the name and the semantics of the fips mode config file.

 * Add convenience macro gcry_fips_mode_active.

 * More self-tests.

 * Documentation cleanups.


Noteworthy changes in version 1.4.2 (2008-09-08)
------------------------------------------------

 * The long missing gcry_mpi_lshift function has been added.

 * RSA key generation now supports a "transient-key" flag.

 * The keygrip computation for ECDSA has been implemented thus ECDSA
   is now fully supported.

 * A few macros have been replaced by functions for better type
   checking.

 * The thread initialization structure now carries version
   information.

 * The manual describes more clearly how to initialize Libgcrypt.

 * The library may now be switched into a FIPS mode.

 * Interface changes relative to the 1.3.0 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 GCRYCTL_OPERATIONAL_P   NEW.
 GCRYCTL_FIPS_MODE_P     NEW.
 GCRYCTL_FORCE_FIPS_MODE NEW.
 gcry_cipher_setkey      NEW: Replaces macro.
 gcry_cipher_setiv       NEW: Replaces macro.
 gcry_cipher_setctr      NEW: Replaces macro.
 gcry_mpi_lshift         NEW.
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Noteworthy changes in version 1.4.1 (2008-04-25)
------------------------------------------------

 * Fixed a bug introduced by 1.3.1 which led to the comsumption of far
   too much entropy for the intial seeding.

 * Improved AES performance for CFB and CBC modes.

 * Removed build problems for the Padlock support.


Noteworthy changes in version 1.4.0 (2007-12-10)
------------------------------------------------

 * New configure option --disable-padlock-support which is mostly
   useful in case of build problems.


Noteworthy changes in version 1.3.2 (2007-12-03)
------------------------------------------------

 * The visibility attribute is now used if supported by the toolchain.

 * The ACE engine of VIA processors is now used for AES-128.

 * The ASN.1 DER template for SHA-224 has been fixed.


Noteworthy changes in version 1.3.1 (2007-10-26)
------------------------------------------------

 * The entire library is now under the LGPL. The helper programs and
   the manual are under the GPL.  Kudos to Peter Gutmann for giving
   permissions to relicense the rndw32 and rndunix modules.

 * The Camellia cipher is now under the LGPL and included by default.

 * Fixed a bug in the detection of symbol prefixes which inhibited the
   build of optimzied assembler code on certain systems.

 * Updated the entropy gatherer for W32.


Noteworthy changes in version 1.3.0 (2007-05-04)
------------------------------------------------

 * Changed the way the RNG gets initialized. This allows to keep it
   uninitialized as long as no random numbers are used.  To override
   this, the new macro gcry_fast_random_poll may be used.  It is in
   general a good idea to spread this macro into the application code
   to make sure that these polls happen often enough.

 * Made the RNG immune against fork without exec.

 * Reading and writing the random seed file is now protected by a
   fcntl style file lock on systems that provide this function.

 * Support for SHA-224 and HMAC using SHA-384 and SHA-512.

 * Support for the SEED cipher.

 * Support for the Camellia cipher.  Note that Camellia is disabled by
   default, and that enabling it changes the license of libgcrypt from
   LGPL to GPL.

 * Support for OFB encryption mode.

 * gcry_mpi_rshift does not anymore truncate the shift count.

 * Reserved algorithm ranges for use by applications.

 * Support for DSA2.

 * The new function gcry_md_debug should be used instead of the
   gcry_md_start_debug and gcry_md_stop_debug macros.

 * New configure option --enable-random-daemon to support a system
   wide random daemon.  The daemon code is experimental and not yet
   very well working.  It will eventually allow to keep a global
   random pool for the sake of short living processes.

 * Non executable stack support is now used by default on systems
   supporting it.

 * Support for Microsoft Windows.

 * Assembler support for the AMD64 architecture.

 * New configure option --enable-mpi-path for optimized builds.

 * Experimental support for ECDSA; should only be used for testing.

 * New control code GCRYCTL_PRINT_CONFIG to print the build
   configuration.

 * Minor changes to some function declarations.  Buffer arguments are
   now typed as void pointer.  This should not affect any compilation.
   Fixed two bugs in return values and clarified documentation.

Noteworthy changes in version 1.2.0 (2004-04-15)
------------------------------------------------

 * First stable release.


Noteworthy changes in version 1.1.94 (2004-03-29)
-------------------------------------------------

 * The support for multi-threaded users goes into its third
   incarnation.  We removed compile time support for thread libraries.
   To support the thread library of your choice, you have to set up
   callback handlers at initialization time.  New data structures, a
   new control command, and default initializers are provided for this
   purpose.

 * Interface changes relative to the 1.1.93 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
libgcrypt-config --thread	OBSOLETE

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Noteworthy changes in version 1.1.93 (2004-03-06)
-------------------------------------------------

 * The automatic thread library detection has finally been removed.
   From now on, only linking explicitely to libgcrypt, libgcrypt-pth
   or libgcrypt-pthread is supported.

Noteworthy changes in version 1.1.92 (2004-02-20)
-------------------------------------------------

 * Minor bug fixes.

 * Included a limited implementation of RFC2268.

 * Changed API of the gcry_ac_ functions.  Only a very few programs
   should be affected by this.

 * Interface changes relative to the 1.1.91 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
GCRY_CIPHER_RFC2268_40          NEW.
gcry_ac_data_set                CHANGED: New argument FLAGS.
gcry_ac_data_get_name           CHANGED: New argument FLAGS.
gcry_ac_data_get_index          CHANGED: New argument FLAGS.

Noteworthy changes in version 1.1.91 (2003-12-19)
-------------------------------------------------

 * Code cleanups and minor bug fixes.


Noteworthy changes in version 1.1.90 (2003-11-14)
-------------------------------------------------

 * The use of the GCRY_WEAK_RANDOM level is now deprecated in favor of
   the new gcry_create_nonce function.

 * gcry_sexp_build now supports a "%b" format to include a memory buffer.

 * Minor configuration fixes.

 * Interface changes relative to the 1.1.44 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcry_create_nonce               NEW
gcry_sexp_build                 ENHANCED


Noteworthy changes in version 1.1.44 (2003-10-31)
-------------------------------------------------

 * Bug fixes and more code cleanups.

 * Enhanced the prime API.

 * Interface changes relative to the 1.1.43 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcry_prime_group_generator      NEW
gcry_prime_release_factors      NEW


Noteworthy changes in version 1.1.43 (2003-09-04)
-------------------------------------------------

 * Bug fixes and internal code cleanups.

 * Support for the Serpent cipher algorithm.

 * Interface changes relative to the 1.1.42 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcry_prime_generate             NEW
gcry_prime_check                NEW


Noteworthy changes in version 1.1.42 (2003-07-31)
-------------------------------------------------

 * Major API cleanup.  Applications need to be converted to the new
   API.  See README.apichanges for hints on how to do that.  Backward
   compatibility is provided where it was possible without too much
   effort and did not collide with the overall sanitization effort.
   However, this is only for ease of transition.  NO DEPRECATED
   FUNCTION OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND
   WILL BE DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE
   LIBRARY.

 * If gcrypt.h is included in sources compiled by GCC 3.1 or later,
   deprecated attributes will warn about use of obsolete functions and
   type definitions.  You can suppress these warnings by passing
   -Wno-deprecated-declarations to the gcc command.

 * gcry_check_version must be called from now on to initialize the
   library, it is not longer optional.

 * Removed `libgcrypt errno' concept.

 * Libgcrypt depends on libgpg-error, a library that provides error
   codes and according functions for all GnuPG components.  Functions
   that used to return error codes asa `int' have been changed to
   return a code of type `gcry_error_t'.  All GCRYERR_* error symbols
   have been removed, since they are now contained in libgpg-error
   (GPG_ERR_*). All functions and types in libgpg-error have also been
   wrapped in Libgcrypt. The new types are gcry_err_code_t and
   gcry_err_source_t.  The new functions are gcry_err_code,
   gcry_err_source, gcry_error, gcry_err_make, gcry_error_from_errno,
   gcry_err_make_from_errno, gcry_err_code_from_errno,
   gcry_err_code_to_errno, gcry_strsource.

 * New function gcry_mpi_dump to help in debugging.

 * Added alternative interface for asymmetric cryptography.

 * CRC-32, CRC-32 a'la RFC 1510, CRC-24 a'la RFC 2440 are now
   supported.

 * SHA-256, SHA-384 and SHA-512 are now supported.

 * 128 bit Twofish is now supported.

 * The random module won't print the "not enough random bytes
   available" anymore.  A new progress status is issued instead.

 * CBC-MAC for block ciphers is now supported, by using a
   GCRY_CIPHER_CBC_MAC cipher flag.

 * CTR mode for block ciphers is now supported.

 * The public RSA exponent can now be specified in key generation.

 * RSA blinding is now supported and is used automatically for RSA
   decryption.  It can be explicitely disabled by using the
   `no-blinding' symbol in the `flags' S-Expression or by using the
   GCRY_AC_FLAG_DATA_NO_BLINDING flag when using the ac interface.

 * gcry_sexp_canon_len does not use a `historically encoded' error
   code anymore.
