I-D ACTION:draft-ietf-smime-rfc2633bis-05.txt



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		: S/MIME Version 3.1 Message Specification
	Author(s)	: B. Ramsdell
	Filename	: draft-ietf-smime-rfc2633bis-05.txt
	Pages		: 0

S/MIME (Secure/Multipurpose Internet Mail Extensions) provides a
consistent way to send and receive secure MIME data. Based on the
popular Internet MIME standard, S/MIME provides the following
cryptographic security services for electronic messaging applications:
authentication, message integrity and non-repudiation of origin (using
digital signatures) and data confidentiality (using encryption).

S/MIME can be used by traditional mail user agents (MUAs) to add
cryptographic security services to mail that is sent, and to interpret
cryptographic security services in mail that is received. However,
S/MIME is not restricted to mail; it can be used with any transport
mechanism that transports MIME data, such as HTTP. As such, S/MIME
takes advantage of the object-based features of MIME and allows secure
messages to be exchanged in mixed-transport systems.

Further, S/MIME can be used in automated message transfer agents that
use cryptographic security services that do not require any human
intervention, such as the signing of software-generated documents and
the encryption of FAX messages sent over the Internet.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-ietf-smime-rfc2633bis-05.txt".
	
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.
