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 a family of Simple Authentication and
Security Layer (SASL; RFC 4422) authentication mechanisms called 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, a mechanism from this family 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.  [STANDARDS TRACK]
