GnuPG - The GNU Privacy Guard suite of programs

GnuPG is a set of programs for public key encryption and digital signatures. The program most users will want to use is the OpenPGP command line tool, named gpg. gpgv is a stripped down version of gpg with no encryption functionality, used only to verify signatures against a trusted keyring. gpgsm is the X.509/CMS (for S/MIME) counterpart of gpg. gpg-agent is a passphrase and private key daemon which may also emulate the ssh-agent.
