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 : PEM Security Services and MIME

This document specifies how the services of MIME and PEM can be used in a
complementary fashion. 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. PEM,
an acronym for "Privacy Enhanced Mail", provides message
authentication/integrity and message encryption services for Internet mail
messages.
An Internet electronic mail message consists of two parts: the headers
and the body. The headers form a collection of field/value
pairs structured according to RFC 822, whilst the body, if structured, is
defined according to MIME. MIME does not provide for the application of
security services.
PEM specifies how to apply encryption and authentication/integrity
services to the contents of a textual electronic mail message
but does not provide message structuring or type labelling
facilities. This document specifies how to use PEM with the
multipart/signed and multipart/encrypted MIME content types to provide
authentication/integrity and encryption services. We refer to the
authentication/integrity service as a digital signature service.
