Hello! I am pleased to announce the availability of Libgcrypt version 1.5.3. This is a *security fix* 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 1.5.3: * Mitigate the Yarom/Falkner flush+reload side-channel attack on RSA secret keys. See <http://eprint.iacr.org/2013/448>. [ Note that Libgcrypt is used by GnuPG 2.x and thus this release fixes the above problem. The fix for GnuPG < 2.0 can be found in the just released GnuPG 1.4.14. ] 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-1.5.3.tar.bz2 (1.5M) ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.5.3.tar.bz2.sig This file is bzip2 compressed.

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: http://g10code.com/gnupg-donation.html Many thanks to all who contributed to Libgcrypt development, be it bug fixes, code, documentation, testing or helping users. Happy hacking, Werner [1] See http://www.gnupg.org/documentation/mailing-lists.html . [2] See http://www.gnupg.org/service.html -- Die Gedanken sind frei.
