size other than 96 bit. [#3764] [also in 1.8.3, 1.7.10]
- Fix incorrect output of AES-keywrap mode for in-place encryption
on some platforms. [also in 1.8.3, 1.7.10]
- Fix the gcry_mpi_ec_curve_point point validation function.
[also in 1.8.3, 1.7.10]
- Fix rare assertion failure in gcry_prime_check. [also in 1.8.3]
- Do not use /dev/srandom on OpenBSD. [also in 1.8.2]
- Fix test suite failure on systems with large pages. [#3351]
[also in 1.8.2]
- Fix test suite to not use mmap on Windows. [also in 1.8.2]
- Fix fatal out of secure memory status in the s-expression parser
on heavy loaded systems. [also in 1.8.2]
* Extended interfaces:
- gcry_sexp_extract_param understands new format specifiers to
directly store to integers and strings.
* Interface changes relative to the 1.8.0 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcry_mpi_get_ui NEW function.
GCRYCTL_AUTO_EXPAND_SECMEM NEW control code.
gcry_sexp_extract_param EXTENDED.
* Release dates of 1.8.x versions:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Version 1.8.2 (2017-12-13)
Version 1.8.3 (2018-06-13)
Version 1.8.4 (2018-10-26)
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]
- Add more extra bytes to the pool after reading a seed file.
- Add the OID SHA384WithECDSA from RFC-7427 to SHA-384.
- 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.

* 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.
* Changes also done in 1.4.6 (2010-07-13):

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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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 1.1.94 (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.
