Method Detail

update

public MessageDigest update(byte[] buffer,
                            int offset,
                            int len)

MessageDigest block update operation. Continues a message-digest operation, processing another message block, and updating the context.

Overrides:

update in class MessageDigest

doFinal

public byte[] doFinal()

MessageDigest finalization. Ends a message-digest operation, writing the the message digest and zeroizing the context.

Overrides:

doFinal in class MessageDigest
