Examples of DigestOutputStream

java.security.DigestOutputStream
A transparent stream that updates the associated message digest using the bits going through the stream.
To complete the message digest computation, call one of the digest methods on the associated message digest after your calls to one of this digest ouput stream's {@link #write(int) write} methods.
It is possible to turn this stream on or off (see {@link #on(boolean) on}). When it is on, a call to one of the write methods results in an update on the message digest. But when it is off, the message digest is not updated. The default is for the stream to be on. @see MessageDigest @see DigestInputStream @version 1.32 05/11/17 @author Benjamin Renaud

DigestOutputStream is used as a filter stream or as the ending stream in order to calculate a digest of a stream.
