Simple Authentication and Security Layer (SASL) Mechanisms

Last Updated

Note

The Simple Authentication and Security Layer (SASL) [RFC4422] is a
method for adding authentication support to connection-based
protocols.  To use this specification, a protocol includes a command
for identifying and authenticating a user to a server and for
optionally negotiating a security layer for subsequent protocol
interactions.  The command has a required argument identifying a SASL
mechanism.

SASL mechanisms are named by strings, from 1 to 20 characters in
length, consisting of upper-case letters, digits, hyphens, and/or
underscores.  SASL mechanism names must be registered with the IANA.
Procedures for registering new SASL mechanisms are described in
[RFC4422].

SASL mechanism names starting with "GS2-" are reserved for SASL
mechanisms which conform to [RFC5801]. 

Registration procedures for SASL mechanism names starting with 
"SCRAM-" are defined in [RFC7677].
