OpenPGP is a standardized data format for encrypted and digitally signed data. It also specifies the format of certificates, commonly referred to as "keys".
It is based on the format introduced by Pretty Good Privacy (PGP) 5 and is standardized in RFC 4880. RFC 5581 added Camellia (another symmetric cipher algorithm). RFC 6637 added Elliptic Curve Cryptography to OpenPGP. However, these extensions are explicitly specified as "optional". An OpenPGP-compliant application is therefore not forced to implement these two extensions. The practical advantage of elliptic curve cryptography is the comparatively small key size for the same encryption strength.
