This document describes updated methods for handling Unicode strings
representing usernames and passwords.  The previous approach was
known as SASLprep (RFC 4013) and was based on stringprep (RFC 3454).
The methods specified in this document provide a more sustainable
approach to the handling of internationalized usernames and
passwords.  The preparation, enforcement, and comparison of
internationalized strings (PRECIS) framework, RFC 7564, obsoletes RFC
3454, and this document obsoletes RFC 4013.

This document is a product of the Preparation and Comparison of Internationalized Strings Working Group of the IETF.

This is now a Proposed Standard.
