Method Summary | |
---|---|
String | getAlgorithmName() |
int | getBlockSize() |
void | init(boolean encrypting, CipherParameters params)
initialise a Serpent cipher.
|
int | processBlock(byte[] in, int inOff, byte[] out, int outOff)
Process one block of input from the array in and write it to
the out array.

void | reset() |
Parameters: encrypting whether or not we are for encryption. params the parameters required to set up the cipher.
Throws: IllegalArgumentException if the params argument is inappropriate.
Parameters: in the array containing the input data. inOff offset into the in array the data starts at. out the array the output data will be copied into. outOff the offset into the out array the output will start at.
Returns: the number of bytes processed and produced.
Throws: DataLengthException if there isn't enough data in in, or space in out. IllegalStateException if the cipher isn't initialised.
