Class java.security.DigestOutputStream
A digest output stream is a filter output stream that is associated with a message digest object. When data is written to the output stream, it is also passed to the message digest object so that when the data has all been written to the output stream, the hash of that data may be obtained from the digest object. You must have an existing output stream and an initialized message digest object to use this class.
