Name

Class java.security.DigestInputStream

Description

A digest input stream is an input filter stream that is associated with a message digest object. As data is read from the input stream, it is automatically passed to its associated message digest object; once all the data has been read, the message digest object will return the hash of the input data. You must have an existing input stream and an initialized message digest object to construct this class; once the data has passed through the stream, call the methods of the message digest object explicitly to obtain the hash.
