Draft IETF SMIME: New ASN.1 Modules for CMS and S/MIME
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.
