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.
This document is a product of the CURves, Deprecating and a Little more Encryption Working Group of the IETF.
This is now a Proposed Standard.
