The GNU project is pleased to announce the availability of Libgcrypt
version 1.5.2.  This is a maintenance release for the stable branch.

Libgcrypt is a general purpose library of cryptographic building
blocks.  It is originally based on code used by GnuPG.  It does not
provide any implementation of OpenPGP or other protocols.  Thorough
understanding of applied cryptography is required to use Libgcrypt.

Noteworthy changes in version 1.5.2:

 * Added support for IDEA.

 * Made the Padlock code work again (regression since 1.5.0).

 * Fixed alignment problems for Serpent.

 * Fixed two bugs in ECC computations.

Source code is hosted at the GnuPG FTP server and its mirrors as
listed at http://www.gnupg.org/download/mirrors.html .  On the primary
server the source file and its digital signatures is:

 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.5.2.tar.bz2 (1.5M)

This file is bzip2 compressed.  A gzip compressed version is also

 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.5.2.tar.gz (1.8M)

Alternativley you may upgrade version 1.5.1 using this patch file:

For help on developing with Libgcrypt you should read the included
manual and optional ask on the gcrypt-devel mailing list [1].  A
listing with commercial support offers for Libgcrypt and related
software is available at the GnuPG web site [2].

The driving force behind the development of Libgcrypt is my company
g10 Code.  Maintenance and improvement of Libgcrypt and related
software takes up most of our resources.  To allow us to continue our
work on free software, we ask to either purchase a support contract,
engage us for custom enhancements, or to donate money:


Many thanks to all who contributed to Libgcrypt development, be it bug
fixes, code, documentation, testing or helping users.

Happy hacking,
