OpenPGP (Pretty Good Privacy) is the Internet open standard used by PGP, GNU Privacy Guard (GnuPG), Hushmail, Veridis, and others for the exchange of encrypted and digitally signed data, and the maintenance of a Public key infrastructure. RFC 2440, created by the OpenPGP Working Group of the IETF, defines the standard and ensures interoperability by specifying a format for messages and algorithms that must be implemented.

The standard was developed because of the wide use of PGP and the desire to make it be a cryptographic standard owned by the community, not any one entity. Although originally designed for email, the standard is now used in many other applications.
