public String	Returns: the name of the algorithm the MAC implements. getAlgorithmName() Return the name of the algorithm the MAC implements.
public int	Returns: the block size for this MAC in bytes. getMacSize() Return the block size for this MAC (in bytes).
public void	init(CipherParameters the key and other data required by the MAC. params) Initialise the MAC.
public void	reset() Reset the MAC.
public void	update(byte the byte to be processed. in) add a single byte to the mac for processing.
public void	update(byte[] the array containing the input. in, int the index in the array the data begins at. inOff, int the length of the input starting at inOff. len)

doFinal	back to summary
public int doFinal(byte[] out, int outOff) throws DataLengthException, IllegalStateException Compute the final stage of the MAC writing the output to the out parameter. doFinal leaves the MAC in the same state it was after the last init. Parameters out:byte[] the array the MAC is to be output to. outOff:int the offset into the out buffer the output is to start at. Exceptions DataLengthException: if there isn't enough space in out. IllegalStateException: if the MAC is not initialised.

doFinal

public int doFinal(byte[] out, int outOff) throws DataLengthException, IllegalStateException

Compute the final stage of the MAC writing the output to the out parameter.

doFinal leaves the MAC in the same state it was after the last init.

Parameters

Exceptions

reset	back to summary
public void reset() Reset the MAC. At the end of resetting the MAC should be in the in the same state it was after the last init (if there was one).

update	back to summary
public void update(byte in) throws IllegalStateException add a single byte to the mac for processing. Parameters in:byte the byte to be processed. Exceptions IllegalStateException: if the MAC is not initialised.

update
