Functions

adjustByteCounts void adjustByteCounts(): adjust the byte counts so that byteCount2 represents the upper long (less 3 bits) word of the byte count.
finish ubyte[digestLength] finish(): Calculate the final hash value.
start void start(): Reset the digest to its initial state. It is not necessary to call start after finish or doFinal.
