Internet Engineering Task Force (IETF) P. Hoffman Request for Comments: 5911 VPN Consortium Category: Informational J. Schaad ISSN: 2070-1721 Soaring Hawk Consulting June 2010 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.

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]Show full document text
