RFC 3278 describes how to use Elliptic Curve Cryptography (ECC)
public-key algorithms in the Cryptographic Message Syntax (CMS).
This document updates RFC 3278 to add support for the SHA2 family of
hash algorithms, Elliptic Curve Digital Signature Algorithm (ECDSA) 224-512, and Key Derivation Functions (KDFs) that utilize SHA2
algorithms.
