[Announce] Libgcrypt 1.6.2 released

[Werner Koch]

Hello!

The GNU project is pleased to announce the availability of Libgcrypt
version 1.6.2.  This is a maintenance release to fix problems found in
the recently released versions.

Libgcrypt is a general purpose library of cryptographic building blocks.
It does not provide any implementation of OpenPGP or other protocols.
Thorough understanding of applied cryptography is required for proper
use Libgcrypt.


Noteworthy changes in version 1.6.2 (2014-08-21)
================================================

 * Map deprecated RSA algo number to the RSA algo number for better
   backward compatibility.

 * Support a 0x40 compression prefix for EdDSA.

 * Improve ARM hardware feature detection and building.

 * Fix powerpc-apple-darwin detection

 * Fix building for the x32 ABI platform.

 * Support building using the latest mingw-w64 toolchain.

 * Fix some possible NULL deref bugs.


Download
========

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 tarball and its digital signature are:

 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.2.tar.bz2 (2418k)
 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.2.tar.bz2.sig

That file is bzip2 compressed.  A gzip compressed version is here:

 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.2.tar.gz (2874k)
 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.2.tar.gz.sig

Alternativley you may upgrade using this patch file:

 ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.1-1.6.2.diff.bz2 (17k)

In order to check that the version of Libgcrypt you are going to build
is an original and unmodified one, you can do it in one of the following
ways:

 * Check the supplied OpenPGP signature.  For example to check the
   signature of the file libgcrypt-1.6.3.tar.bz2 you would use this
   command:

     gpg --verify libgcrypt-1.6.3.tar.bz2.sig

   This checks whether the signature file matches the source file.  You
   should see a message indicating that the signature is good and made
   by the release signing key 4F25E3B6 which is certified by my well
   known key 1E42B367.  To retrieve the keys you may use the command
   "gpg --fetch-key finger:wk at g10code.com".

 * If you are not able to use GnuPG, you have to verify the SHA-1
   checksum:

     sha1sum libgcrypt-1.6.3.tar.bz2

   and check that the output matches the first line from the
   following list:

cc31aca87e4a3769cb86884a3f5982b2cc8eb7ec  libgcrypt-1.6.2.tar.bz2
cdaf2bdd5f34b20f4f9d926536673c15b857d2e6  libgcrypt-1.6.2.tar.gz

Support
=======

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:

Thanks
======

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


Happy hacking,

  Werner
