New ASN.1 Modules for Cryptographic Message Syntax (CMS) and S/MIME
Abstract
The Cryptographic Message Syntax (CMS) format, and many associated
formats, are expressed using ASN.1. The current ASN.1 modules
conform to the 1988 version of ASN.1. This document updates those
ASN.1 modules to conform to the 2002 version of ASN.1. There are no
bits-on-the-wire changes to any of the formats; this is simply a
change to the syntax.

RFC 5911 New ASN.1 for CMS and S/MIME June 2010
1. Introduction
Some developers would like the IETF to use the latest version of
ASN.1 in its standards. Most of the RFCs that relate to security
protocols still use ASN.1 from the 1988 standard, which has been
deprecated. This is particularly true for the standards that relate
to PKIX, CMS, and S/MIME.
This document updates the following RFCs to use ASN.1 modules that
conform to the 2002 version of ASN.1 [ASN1-2002]. Note that not all
the modules are updated; some are included to simply make the set
complete.
o RFC 3370, CMS Algorithms [RFC3370]
o RFC 3565, Use of AES in CMS [RFC3565]
o RFC 3851, S/MIME Version 3.1 Message Specification [RFC3851]
