GnuPG is Free Software . GnuPG 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".
