CFRG Elliptic Curve Diffie-Hellman and Signatures in JSON Object Signing and Encryption
Overview
RFC 8037, “CFRG Elliptic Curve Diffie-Hellman and Signatures in JSON Object Signing and Encryption”, is a Proposed Standard document published in January 2017 by I. Liusvaara. It has since been updated by RFC 9864. The canonical text is published by the RFC Editor.
Abstract
This document defines how to use the Diffie-Hellman algorithms "X25519" and "X448" as well as the signature algorithms "Ed25519" and "Ed448" from the IRTF CFRG elliptic curves work in JSON Object Signing and Encryption (JOSE).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
