GCRY_MD_FLAG_BUGEMU1 NEW (minor API change).
Noteworthy changes in version 1.6.0 (2013-12-16)
------------------------------------------------
* 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].
* Added support for Deterministic DSA as per RFC-6969.
* Added support for curve Ed25519.
* Added a scatter gather hash convenience function.

gcry_mpi_aprint and gcry_mpi_scan.
* The algorithm ids GCRY_PK_ECDSA and GCRY_PK_ECDH are now
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.
* Added debug helper functions.
* Interface changes relative to the 1.5.0 release:

------------------------------------------------
* New function gcry_kdf_derive implementing OpenPGP S2K algorithms
and PBKDF2.
* Support for WindowsCE.
* Support for ECDH.
* Support for OAEP and PSS methods as described by RFC-3447.

* Uses the Intel AES-NI instructions if available.
* The use of the deprecated Alternative Public Key Interface
(gcry_ac_*) will now print compile time warnings.
* The module register subsystem has been deprecated. This subsystem
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.
* CTR mode may now be used with data chunks of arbitrary length.

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_FIPS_MODE_P NEW.
GCRYCTL_FORCE_FIPS_MODE NEW.
gcry_cipher_setkey NEW: Replaces macro.
gcry_cipher_setiv NEW: Replaces macro.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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.

------------------------------------------------
* 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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.
* Interface changes relative to the 1.1.12 release:

The performance of the Unix random gatherer module (rndunix) is not
very good and it does not keep the entropy pool over multiple
invocations of Libgcrypt base applications. The suggested way to
overcome this problem is to use the
Entropy Gathering Daemon (EGD)
