Network Working Group J. Schaad Internet-Draft Soaring Hawk Consulting Intended status: Informational S. Turner Expires: September 2, 2010 IECA, Inc. March 1, 2010 Additional New ASN.1 Modules draft-turner-additional-new-asn-00 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 some auxiliary 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. Status of this Memo This Internet-Draft is submitted to IETF in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups.

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time.

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]. RFC 4049, BinaryTime: An Alternate Format for Representing Date and Time in ASN.1 [RFC4049] RFC 4073, Protecting Multiple Contents with the Cryptographic Message Syntax (CMS) [RFC4073] RFC 5752, Multiple Signatures in Cryptographic Message Syntax (CMS) [RFC5752] Note that some of the modules in this document get some of their definitions from places different than the modules in the original RFCs. The idea is that these modules, when combined with the modules in [I-D.ietf-pkix-new-asn1] and [I-D.ietf-smime-new-asn1] can stand on their own and do not need to import definitions from anywhere else. 1.1. Requirements Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
