The ATH implementation (src/ath*) has been taken from GPGME and relicensed to the LGPL by the copyright holder of GPGME (g10 Code GmbH); it is now considered to be a part of Libgcrypt. Most of the stuff in mpi has been taken from an old GMP library version by Torbjorn Granlund . The files cipher/rndunix.c and cipher/rndw32.c are based on those files from Cryptlib. Copyright Peter Gutmann, Paul Kendall, and Chris Wedgwood 1996-1999. The ECC code cipher/ecc.c was based on code by Sergi Blanch i Torne, sergi at calcurco dot org. The implementation of the Camellia cipher has been been taken from the original NTT provided GPL source. The CAVS testing program tests/cavs_driver.pl is not to be considered a part of libgcrypt proper. We distribute it merely for convenience. It has a permissive license and is copyrighted by atsec information security corporation. See the file for details. The file salsa20.c is based on D.J. Bernstein's public domain code and taken from Nettle. Copyright 2012 Simon Josefsson and Niels Möller.

See below for details. The documentation is licensed under the GPLv2 (or later), see below. Excerpt from upstream's README: The library is distributed under the terms of the GNU Lesser General Public License (LGPL); see the file COPYING.LIB for the actual terms. The helper programs (e.g. gcryptrnd and getrandom) as well as the documentation are distributed under the terms of the GNU General Public License (GPL); see the file COPYING for the actual terms. This library used to be available under the GPL - this was changed with version 1.1.7 with the rationale that there are now many free crypto libraries available and many of them come with capabilities similar to Libcrypt. We decided that to foster the use of cryptography in Free Software an LGPLed library would make more sense because it avoids problems due to license incompatibilities between some Free Software licenses and the GPL. Please note that in many cases it is better for a library to be licensed under the GPL, so that it provides an advantage for free software projects. The Lesser GPL is so named because it does less to protect the freedom of the users of the code that it covers. See http://www.gnu.org/philosophy/why-not-lgpl.html for more explanation.
