Use of the Elliptic Curve Diffie-Hellman Key Agreement Algorithm with X25519 and X448 in the Cryptographic Message Syntax
Overview
RFC 8418, “Use of the Elliptic Curve Diffie-Hellman Key Agreement Algorithm with X25519 and X448 in the Cryptographic Message Syntax”, is a Proposed Standard document published in August 2018 by R. Housley. The canonical text is published by the RFC Editor.
Abstract
This document describes the conventions for using the Elliptic Curve Diffie-Hellman (ECDH) key agreement algorithm with curve25519 and curve448 in the Cryptographic Message Syntax (CMS).
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.
