============
Libgcrypt used to be part of GnuPG but has been taken out into its own
package on 2000-12-21.
Most of the stuff in mpi has been taken from an old GMP library
version by Torbjorn Granlund <tege@noisy.tmg.se>.
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.

OCB is covered by several patents but may be used freely by most
software. See http://web.cs.ucdavis.edu/~rogaway/ocb/license.htm .
In particular license 1 is suitable for Libgcrypt: See
http://web.cs.ucdavis.edu/~rogaway/ocb/license1.pdf for the full
license document; it basically says:
License 1 — License for Open-Source Software Implementations of OCB
(Jan 9, 2013)
Under this license, you are authorized to make, use, and
distribute open-source software implementations of OCB. This
license terminates for you if you sue someone over their
open-source software implementation of OCB claiming that you have
a patent covering their implementation.
License for Open Source Software Implementations of OCB
January 9, 2013
1 Definitions
1.1 “Licensor” means Phillip Rogaway.
1.2 “Licensed Patents” means any patent that claims priority to United
States Patent Application No. 09/918,615 entitled “Method and Apparatus
for Facilitating Efficient Authenticated Encryption,” and any utility,
divisional, provisional, continuation, continuations-in-part, reexamination,
reissue, or foreign counterpart patents that may issue with respect to the
aforesaid patent application. This includes, but is not limited to, United
States Patent No. 7,046,802; United States Patent No. 7,200,227; United
States Patent No. 7,949,129; United States Patent No. 8,321,675 ; and any
patent that issues out of United States Patent Application No. 13/669,114.
1.3 “Use” means any practice of any invention claimed in the Licensed Patents.
1.4 “Software Implementation” means any practice of any invention
claimed in the Licensed Patents that takes the form of software executing on
a user-programmable, general-purpose computer or that takes the form of a
computer-readable medium storing such software. Software Implementation does
not include, for example, application-specific integrated circuits (ASICs),
field-programmable gate arrays (FPGAs), embedded systems, or IP cores.
1.5 “Open Source Software” means software whose source code is published
and made available for inspection and use by anyone because either (a) the
source code is subject to a license that permits recipients to copy, modify,
and distribute the source code without payment of fees or royalties, or
(b) the source code is in the public domain, including code released for
public use through a CC0 waiver. All licenses certified by the Open Source
Initiative at opensource.org as of January 9, 2013 and all Creative Commons
licenses identified on the creativecommons.org website as of January 9,
2013, including the Public License Fallback of the CC0 waiver, satisfy these
requirements for the purposes of this license.
1.6 “Open Source Software Implementation” means a Software
Implementation in which the software implicating the Licensed Patents is
Open Source Software. Open Source Software Implementation does not include
any Software Implementation in which the software implicating the Licensed
Patents is combined, so as to form a larger program, with software that is
not Open Source Software.
2 License Grant
2.1 License. Subject to your compliance with the term s of this license,
including the restriction set forth in Section 2.2, Licensor hereby
grants to you a perpetual, worldwide, non-exclusive, non-transferable,
non-sublicenseable, no-charge, royalty-free, irrevocable license to practice
any invention claimed in the Licensed Patents in any Open Source Software
Implementation.
2.2 Restriction. If you or your affiliates institute patent litigation
(including, but not limited to, a cross-claim or counterclaim in a lawsuit)
against any entity alleging that any Use authorized by this license
infringes another patent, then any rights granted to you under this license
automatically terminate as of the date such litigation is filed.
3 Disclaimer
YOUR USE OF THE LICENSED PATENTS IS AT YOUR OWN RISK AND UNLESS REQUIRED
BY APPLICABLE LAW, LICENSOR MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE LICENSED PATENTS OR ANY PRODUCT EMBODYING ANY LICENSED
PATENT, EXPRESS OR IMPLIED, STATUT ORY OR OTHERWISE, INCLUDING, WITHOUT
LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR
PURPOSE, OR NONINFRINGEMENT. IN NO EVENT WILL LICENSOR BE LIABLE FOR ANY
CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN CONTRACT, TORT OR OTHERWISE,
ARISING FROM OR RELATED TO ANY USE OF THE LICENSED PATENTS, INCLUDING,
WITHOUT LIMITATION, DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE
OR SPECIAL DAMAGES, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES PRIOR TO SUCH AN OCCURRENCE.
