Elliptic Curve Cryptography Cipher Suites for Transport Layer Security Versions 1.2 and Earlier

Overview

RFC 8422, “Elliptic Curve Cryptography Cipher Suites for Transport Layer Security Versions 1.2 and Earlier”, is a Proposed Standard document published in August 2018 by Y. Nir, S. Josefsson, M. Pegourie-Gonnard. It obsoletes RFC 4492. It has since been updated by RFC 8996. The canonical text is published by the RFC Editor.

Abstract

This document describes key exchange algorithms based on Elliptic Curve Cryptography (ECC) for the Transport Layer Security (TLS) protocol. In particular, it specifies the use of Ephemeral Elliptic Curve Diffie-Hellman (ECDHE) key agreement in a TLS handshake and the use of the Elliptic Curve Digital Signature Algorithm (ECDSA) and Edwards-curve Digital Signature Algorithm (EdDSA) as authentication mechanisms.

This document obsoletes RFC 4492.

Abstract as published in the RFC, via rfc-editor.org.

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.
