SASLprep: Stringprep Profile for User Names and Passwords.

The use of simple user names and passwords in authentication and authorization is pervasive on the Internet. To increase the likelihood that user name and password input and comparison work in ways that make sense for typical users throughout the world, this document defines rules for preparing internationalized user names and passwords for comparison. For simplicity and implementation ease, a single algorithm is defined for both user names and passwords.
