Fields Summary

Constructors Summary

Methods Summary
public java.lang.String	getAlgorithmName() Return the name of the algorithm the cipher implements. return the name of the algorithm the cipher implements.
public int	getBlockSize() Return the block size for this cipher (in bytes). return the block size for this cipher in bytes.
public void	init(boolean forEncryption, CipherParameters params) Initialise the cipher. param forEncryption if true the cipher is initialised for encryption, if false for decryption. param param the key and other data required by the cipher. exception IllegalArgumentException if the params argument is inappropriate.
public 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. param in the array containing the input data. param inOff offset into the in array the data starts at. param out the array the output data will be copied into. param outOff the offset into the out array the output will start at. exception DataLengthException if there isn't enough data in in, or space in out. exception IllegalStateException if the cipher isn't initialised. return the number of bytes processed and produced.
public void	reset() Reset the cipher. After resetting the cipher is in the same state as it was after the last init (if there was one).
