Using SHA2 Algorithms with Cryptographic Message Syntax
Abstract
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.

1. Introduction
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].
This document also specifies the algorithm identifiers and parameters
for use of SHA-224, SHA-256, SHA-384, and SHA-512 with DSA [DSS], RSA
(RSASSA-PKCS1-v1_5) [RFC3447], and ECDSA [DSS].
This document does not define new identifiers; they are taken from
[RFC3874], [RFC4055], and [RFC5758]. Additionally, the parameters
follow the conventions specified therein. Therefore, there is no
