GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC4880.

GnuPG allows encryption and signing of data and communication. It features a versatile key management system as well as access modules for all kinds of public key directories. The gpg command line tool has features for easy integration with other applications. A wealth of front-end applications and libraries are available.
