GnuPG is compliant with RFC 4880, which is the current IETF standards track specification of OpenPGP. Current versions of PGP (and Veridis' Filecrypt) are interoperable with GnuPG and other OpenPGP-compliant systems.

GPG is a part of the Free Software Foundation's GNU software project, and has received major funding from the German government. Released under the terms of version 3 of the GNU General Public License
