------------------------------------------------
* Bug fixes:

- 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.
* 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-6979.
* Added support for curve Ed25519.
* Added a scatter gather hash convenience function.
* Added several MPI amd SEXP helper functions.
* Added support for negative numbers to gcry_mpi_print,
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:

Noteworthy changes in version 1.5.0 (2011-06-29)
------------------------------------------------
* 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.
* Fixed PKCS v1.5 code to always return the leading zero.
* New format specifiers "%M" and "%u" for gcry_sexp_build.
* Support opaque MPIs with "%m" and "%M" in gcry_sexp_build.

* gcry_mpi_cmp applied to opaque values has a defined semantic now.
* 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):
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* New variants of the TIGER algorithm.
* New cipher algorithm mode for AES-WRAP.
* Changes also done in 1.4.5 (2009-12-11):

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:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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.

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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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:

Libgcrypt - The GNU Crypto Library

Libgcrypt is free software. See the file AUTHORS for full copying
notices, and LICENSES for notices about contributions that require
these additional notices to be distributed.
Overview
--------
Libgcrypt is a general purpose crypto library based on the code
used in GnuPG. Libgcrypt depends on the library `libgpg-error',
which must be installed correctly before Libgcrypt is to be built.
Libgcrypt is distributed under the LGPL, see the section "License"
below for details.
Build Instructions
------------------
The download canonical location for libgcrypt is:
https://gnupg.org/ftp/gcrypt/libgcrypt/
To build libgcrypt you need libgpg-error:
https://gnupg.org/ftp/gcrypt/libgpg-error/
You should get the latest versions of course.
After building and installing the libgpg-error package, you may
continue with Libgcrypt installation as with allmost all GNU
packages, you just have to do
./configure
make
make check
make install
The "make check" is not required but a good idea to see whether
the library works as expected. The check takes some while and
prints some benchmarking results. Before doing "make install" you
probably need to become root.
To build libgcrypt for Microsoft Windows, you need to have the
mingw32 cross-building toolchain installed. Instead of running a
plain configure you use
./autogen.sh --build-w32
make
make install
By default this command sequences expectsd a libgpg-error
installed below $HOME/w32root and installs libgcrypt to that
directory too. See the autogen.sh code for details.
The documentation is available as an Info file (gcrypt.info). To
build documentation in PDF, run this:
cd doc
make pdf
Mailing List
------------
You may want to join the developer's mailing list
gcrypt-devel@gnupg.org by sending mail with a subject of
"subscribe" to gcrypt-devel-request@gnupg.org. An archive of this
list is available at https://lists.gnupg.org .
Configure options
-----------------
Here is a list of configure options which are sometimes useful
for installation.
--enable-large-data-tests
With this option a "make check" will take really
long due to extra checks for the hash algorithms.
--enable-m-guard
Enable the integrated malloc checking code. Please
note that this feature does not work on all CPUs
(e.g. SunOS 5.7 on UltraSparc-2) and might give
you a bus error.
--disable-asm
Do not use assembler modules. It is not possible
to use this on some CPU types.
--enable-ld-version-script
Libgcrypt tries to build a library where internal
symbols are not exported. This requires support
from ld and is currently enabled for a few OSes.
If you know that your ld supports the so called
ELF version scripts, you can use this option to
force its use. OTOH, if you get error message
from the linker, you probably want to use this
option to disable the use of version scripts.
Note, that you should never ever use an
undocumented symbol or one which is prefixed with
an underscore.
--enable-ciphers=list
--enable-pubkey-ciphers=list
--enable-digests=list
If not otherwise specified, all algorithms
included in the libgcrypt source tree are built.
An exception are algorithms, which depend on
features not provided by the system, like 64bit
data types. With these switches it is possible
to select exactly those algorithm modules, which
should be built. The algorithms are to be
separated by spaces, commas or colons. To view
the list used with the current build the program
tests/version may be used.
--disable-endian-check
Don't let configure test for the endianness but
try to use the OS provided macros at compile
time. This is helpful to create OS X fat binaries.
--enable-random-daemon
Include support for a global random daemon and
build the daemon. This is an experimental feature.
--enable-mpi-path=EXTRA_PATH
Prepend EXTRA_PATH to list of CPU specific
optimizations. For example, if you want to add
optimizations forn a Intel Pentium 4 compatible
CPU, you may use
--enable-mpi-path=pentium4/sse2:pentium4/mmx
Take care: The generated library may crash on
non-compatible CPUs.
--enable-random=NAME
Force the use of the random gathering module
NAME. Default is either to use /dev/random or
the auto mode. Possible values for NAME are:
egd - Use the module which accesses the
Entropy Gathering Daemon. See the webpages
for more information about it.
unix - Use the standard Unix module which does not
have a very good performance.
linux - Use the module which accesses /dev/random.
This is the first choice and the default one
for GNU/Linux or *BSD.
auto - Compile linux, egd and unix in and
automagically select at runtime.
--enable-hmac-binary-check
Include support to check the binary at runtime
against a HMAC checksum. This works only in FIPS
mode and on systems providing the dladdr function.
--disable-padlock-support
Disable support for the PadLock engine of VIA
processors. The default is to use PadLock if
available. Try this if you get problems with
assembler code.
--disable-aesni-support
Disable support for the AES-NI instructions of
newer Intel CPUs. The default is to use AES-NI
if available. Try this if you get problems with
assembler code.
--disable-O-flag-munging
Some code is too complex for some compilers while
in higher optimization modes, thus the compiler
invocation is modified to use a lower
optimization level. Usually this works very well
but on some platforms these rules break the
invocation. This option may be used to disable
the feature under the assumption that either good
CFLAGS are given or the compiler can grok the code.
Build Problems
--------------
If you have a problem with a certain release, please first check
the Release-info URL given in the NEWS file.
We can't check all assembler files, so if you have problems
assembling them (or the program crashes) use --disable-asm with
./configure. If you opt to delete individual replacement files in
hopes of using the remaining ones, be aware that the configure
scripts may consider several subdirectories to get all available
assembler files; be sure to delete the correct ones. Never delete
udiv-qrnnd.S in any CPU directory, because there may be no C
substitute (in mpi/genereic). Don't forget to delete
"config.cache" and run "./config.status --recheck". We got a few
reports about problems using versions of gcc earlier than 2.96
along with a non-GNU assembler (as). If this applies to your
platform, you can either upgrade gcc to a more recent version, or
use the GNU assembler.
Some make tools are broken - the best solution is to use GNU's
make. Try gmake or grab the sources from a GNU archive and
install them.
Specific problems on some machines:
* IBM RS/6000 running AIX
Due to a change in gcc (since version 2.8) the MPI stuff may
not build. In this case try to run configure using:
CFLAGS="-g -O2 -mcpu=powerpc" ./configure
* SVR4.2 (ESIX V4.2 cc)
Due to problems with the ESIX as(1), you probably want to do:
CFLAGS="-O -K pentium" ./configure --disable-asm
* SunOS 4.1.4
./configure ac_cv_sys_symbol_underscore=yes
* Sparc64 CPUs
We have reports about failures in the AES module when
compiling using gcc (e.g. version 4.1.2) and the option -O3;
using -O2 solves the problem.

* / :: Switch to opaque format.
* & :: Switch to buffer descriptor mode - see below.

*
* In general parameter names are single letters. To use a string for
* a parameter name, enclose the name in single quotes.
*
* Unless in gcry_buffer_t mode for each parameter name a pointer to
* an MPI variable is expected that must be set to NULL prior to
* invoking this function, and finally a NULL is expected. Example:
*
* _gcry_sexp_extract_param (key, NULL, "n/x+ed",
* &mpi_n, &mpi_x, &mpi_e, NULL)
*
* This stores the parameter "N" from KEY as an unsigned MPI into

* parameter "E" again as an unsigned MPI into MPI_E.
*
* If in buffer descriptor mode a pointer to gcry_buffer_t descriptor
* is expected instead of a pointer to an MPI. The caller may use two
* different operation modes: If the DATA field of the provided buffer
* descriptor is NULL, the function allocates a new buffer and stores
* it at DATA; the other fields are set accordingly with OFF being 0.
* If DATA is not NULL, the function assumes that DATA, SIZE, and OFF
* describe a buffer where to but the data; on return the LEN field
* receives the number of bytes copied to that buffer; if the buffer
* is too small, the function immediately returns with an error code
* (and LEN set to 0).
*
* PATH is an optional string used to locate a token. The exclamation
* mark separated tokens are used to via gcry_sexp_find_token to find
* a start point inside SEXP.
*
* The function returns 0 on success. On error an error code is
* returned, all passed MPIs that might have been allocated up to this
* point are deallocated and set to NULL, and all passed buffers are
* either truncated if the caller supplied the buffer, or deallocated
* if the function allocated the buffer.
