A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the S/MIME Mail Security Working Group of the IETF.
Title : Compressed Data Content Type for S/MIME
Author(s) : P. Gutmann
Filename : draft-ietf-smime-compression-06.txt
Date : 04-Sep-01
The Cryptographic Message Syntax data format doesn't currently contain
any provisions for compressing data before processing it. 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.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
