The GNU Privacy Guard

GnuPG is a complete and free replacement for PGP. Because it does not use the patented IDEA algorithm, it can be used without any restrictions. GnuPG is a RFC2440 (OpenPGP) compliant application.

Version 1.0.0 has been released on September 7th, 1999. The current stable version is 1.2.6.

GnuPG is Free Software. It can be freely used, modified and distributed under the terms of the GNU General Public License.

PGP, on which OpenPGP is based, was originally developed by Philip Zimmermann in the early 1990s.

Project Aegypten provides Sphinx-Clients (Mutt, KMail, ...) compatible to S/MIME within a GnuPG framework. Within this project a few new tools have been developed, most notably "gpgsm" as the S/MIME counterpart of "gpg".
