This document defines a format for using compressed data as a
Cryptographic Message Syntax (CMS) content type.  Compressing data
before transmission provides a number of advantages, including the
elimination of data redundancy which could help an attacker, speeding
up processing by reducing the amount of data to be processed by later
steps (such as signing or encryption), and reducing overall message
size.  Although there have been proposals for adding compression at
other levels (for example at the MIME or SSL level), these don't
address the problem of compression of CMS content unless the
compression is supplied by an external means (for example by
intermixing MIME and CMS).

This document is a product of the S/MIME Mail Security Working Group
of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
