RFC 4013: SASLprep: Stringprep Profile for User Names and Passwords

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 7613.

Current document in this lineage: RFC 8265 — Preparation, Enforcement, and Comparison of Internationalized Strings Representing Usernames and Passwords

In plain English — editorial summary, not part of the RFC

This document describes how to prepare Unicode strings representing user names and passwords for comparison. The document defines the "SASLprep" profile of the "stringprep" algorithm to be used for both user names and passwords. This profile is intended to be used by Simple Authentication and Security Layer (SASL) mechanisms (such as PLAIN, CRAM-MD5, and DIGEST-MD5), as well as other protocols exchanging simple user names and/or passwords.
