This document specifies the algorithm identifiers and specifies parameters for the message digest algorithms SHA-224, SHA-256, SHA-384, and SHA-512 for use with the Cryptographic Message Syntax (CMS) [RFC5652]. The message digest algorithms are defined in [SHS] and reference code is provided in [RFC4634].

         Using SHA2 Algorithms with Cryptographic Message Syntax


   This document describes the conventions for using the Secure Hash    Algorithm (SHA) message digest algorithms (SHA-224, SHA-256, SHA-384,    SHA-512) with the Cryptographic Message Syntax (CMS).  It also    describes the conventions for using these algorithms with the CMS and    the Digital Signature Algorithm (DSA), Rivest Shamir Adleman (RSA),    and Elliptic Curve DSA (ECDSA) signature algorithms.  Further, it    provides SMIMECapabilities attribute values for each algorithm.
