getMacSize in interface Macpublic void update(byte in)
Mac
update in interface Macin - the byte to be processed.
public void update(byte[] in,
int inOff,

update in interface Macin - the array containing the input.inOff - the index in the array the data begins at.len - the length of the input starting at inOff.
public int doFinal(byte[] out,
int outOff)
MacdoFinal leaves the MAC in the same state it was after the last init.
doFinal in interface Macout - the array the MAC is to be output to.outOff - the offset into the out buffer the output is to start at.public void reset()
reset in interface Mac
