Overview: OpenPGP is a non-proprietary protocol for encrypting email using public key cryptography. The OpenPGP protocol defines standard formats for encrypted messages, signatures, and certificates for exchanging public keys. Beginning in 1997, the OpenPGP Working Group was formed in the Internet Engineering Task Force (IETF) to define this standard that had formerly been a proprietary product since 1991. Over the past decade, PGP, and later OpenPGP, has become the standard for nearly all of the world's encrypted email. As an IETF Proposed Standard (RFC 4880), OpenPGP may be implemented by any company without paying any licensing fees. The OpenPGP Alliance brings companies together to pursue a common goal of promoting the same standard for email encryption and to apply the PKI that has emerged from the OpenPGP community to other non-email applications.
