Abstract

The Internet Research Task Force (IRTF) Crypto Forum Research Group (CFRG) selected new Diffie-Hellman algorithms ("X25519" and "X448"; [RFC7748]) and signature algorithms ("Ed25519" and "Ed448"; [RFC8032]) for asymmetric key cryptography. This document defines how to use those algorithms in JOSE in an interoperable manner.
