OpenPGP OpenPGP is a message format for exchanging cryptographic key
        material and signed and/or encrypted documents. It is defined
        in RFC 2440.


PGP     PGP is a trademark held by various companies in the course of
        history (the current trademark holder appears to be PGP
        Corporation). In the beginning, "PGP" was an abbreviation of
        "Pretty Good Privacy", a software package releaed by Phil
        Zimmerman which implemented cryptography using a format which
        became the basis for OpenPGP. The trademark "PGP" has been used
        for many products, most of them involving cryptography. Some of
        these products can process OpenPGP messages.


GnuPG   GnuPG ("GNU Privacy Guard") is a free (libre) implementation of
        the OpenPGP format. It is part of the GNU Project and released
        under the GNU General Public License (GPL).


GPG     "GPG" is an unofficial abbreviation of "GNU Privacy Guard". The
        binary is also called "gpg".
