Known Direct Subclasses
com.sun.security.sasl.digest.DigestMD5Base
Imports
javax.security.sasl.*, java.io.*, java.util.Map, .StringTokenizer, java.util.logging.Logger, .Level, sun.security.util.HexDumpEncoder
The base class used by client and server implementations of SASL mechanisms to process properties passed in the props argument and strings with the same format (e.g., used in digest-md5). Also contains utilities for doing int to network-byte-order transformations.
