# Cyrus SASL library, version 1.5

SASL (Simple Authentication Security Layer) is an Internet standards-track method for remote computers to authenticate. The Cyrus SASL library makes supporting various SASL mechanisms easy for both client and server writers.

The Cyrus project is the implementation of an enterprise mail system by the Carnegie Mellon University Computing Services Department. We are interested in scalable, easy to administer systems.
