New ASN.1 Modules for Cryptographic Message Syntax and S/MIME
RFC 5911, “New ASN.1 Modules for Cryptographic Message Syntax and S/MIME”, is an Informational document published in June 2010 by P. Hoffman, J. Schaad. It has since been updated by RFC 6268. The canonical text is published by the RFC Editor.
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. This document is not an Internet Standards Track specification; it is published for informational purposes.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
