This document describes how to handle Unicode strings representing simple user names and passwords, primarily for purposes of comparison. This profile is intended to be used by Simple Authentication and Security Layer (SASL) mechanisms (such as PLAIN and SCRAM-SHA-1), as well as other protocols that exchange simple user names or passwords. This document obsoletes RFC 4013.
