An extension for Elliptic Curve Cryptography was defined in [RFC 6637](https://www.rfc-editor.org/rfc/rfc6637), specifying the use of three NIST prime field curves.
Some implementations explored other non-standardized extensions. Notably, algorithms based on Curve 25519 were tentatively defined in the [rfc4880bis](https://www.ietf.org/archive/id/draft-ietf-openpgp-rfc4880bis-10.html#name-elliptic-curve-cryptography) document. These algorithms are widely used, even though rfc4880bis has never been finalized as a new version of the standard.
