Additional New ASN.1 Modules for the Cryptographic Message Syntax and the Public Key Infrastructure Using X.509
RFC 6268, “Additional New ASN.1 Modules for the Cryptographic Message Syntax and the Public Key Infrastructure Using X.509”, is an Informational document published in July 2011 by J. Schaad, S. Turner. It updates RFC 5911. 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 some auxiliary ASN.1 modules to conform to the 2008 version of ASN.1; the 1988 ASN.1 modules remain the normative version. 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
