Functions

finish ubyte[] finish(ubyte[] output): * close the MAC, producing the final MAC value. The doFinal * call leaves the MAC reset().
finish ubyte[macSize] finish(): Undocumented in source. Be warned that the author may not have intended to support it.
put void put(ubyte[] input): update the MAC with a block of bytes.
reset void reset(): reset the digest back to it's initial state.
start void start(ubyte[] macKey)
