Use of Edwards-Curve Digital Signature Algorithm Signatures in the Cryptographic Message Syntax
RFC 8419, “Use of Edwards-Curve Digital Signature Algorithm Signatures 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 specifies the conventions for using the Edwards-curve Digital Signature Algorithm (EdDSA) for curve25519 and curve448 in the Cryptographic Message Syntax (CMS). For each curve, EdDSA defines the PureEdDSA and HashEdDSA modes. However, the HashEdDSA mode is not used with the CMS. In addition, no context string is used with the 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.
