A Revised Internet-Draft is available from the on-line Internet-Drafts
directories. This draft is a work item of the Privacy-Enhanced Electronic
Mail Working Group of the IETF.
Title : Security Multiparts for MIME: Multipart/Signed and
Multipart/Encrypted
Author(s) : J. Galvin, S. Murphy, S. Crocker, N. Freed
Filename : draft-ietf-pem-sigenc-01.txt
Pages : 11

This document defines two new content types for specifying the application
of security services to MIME message bodies. MIME, an acronym for
"Multipurpose Internet Mail Extensions", defines the format of the contents
of Internet mail messages and provides for multi-part textual and
non-textual message bodies. The new content types are subtypes of
multipart: signed and encrypted. Each will contain two body parts: one for
the protected data and one for the control information necessary to remove
the protection. Two control information content types are defined,
application/signature and application/keys, one for each of the multiparts.
The first is to be used when a body part is digitally signed; the second is
to be used when a body part is encrypted. The contents of each of the
multipart body parts is determined by the value of the protocol parameter,
which is required to be present.

Send a message to: mailserv(_at_)ds(_dot_)internic(_dot_)net(_dot_) In the
body type:
"FILE /internet-drafts/draft-ietf-pem-sigenc-01.txt".
NOTE: The mail server at ds.internic.net 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.
