	Title		: Salted Challenge Response Authentication Mechanism (SCRAM)
	Author(s)	: C. Newman, et al.

The secure authentication mechanism most widely deployed and used by
    Internet application protocols is the transmission of clear-text
    passwords over a channel protected by Transport Layer Security
    (TLS).  There are some significant security concerns with that
    mechanism, which could be addressed by the use of a challenge

    response authentication mechanism protected by TLS. Unfortunately,
    the challenge response mechanisms presently on the standards track
    all fail to meet requirements necessary for widespread deployment,
    and have had success only in limited use.

    This specification describes the Salted Challenge Response
    Authentication Mechanism (SCRAM), which addresses the security
    concerns and meets the deployability requirements. When used in
    combination with TLS or an equivalent security layer, this mechanism
    could improve the status-quo for application protocol authentication
    and provide a suitable choice for a mandatory-to-implement mechanism
    for future application protocol standards.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-newman-auth-scram-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.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
