Class BlockCipherParameterSpec

public class BlockCipherParameterSpec extends Object implements AlgorithmParameterSpec

Block cipher parameters in GNU Crypto are the cipher's name, its block and key sizes, and an optional initialization vector.

Version: $Revision: 1.2 $

Field Summary
protected int	blockSize The cipher's block size, in bytes.
protected byte[]	iv The initialization vector.
protected int	keySize The cipher's key size, in bytes.

Constructor Summary
	BlockCipherParameterSpec(byte[] iv, int blockSize, int keySize) Create a new parameter specification.
	BlockCipherParameterSpec(int blockSize, int keySize) Create a new parameter specification with no IV.

Method Summary
int	getBlockSize() Get the block size of the cipher these parameters are for.
byte[]	getIV() Get the initialization vector for the cipher, or `null` if there is no IV.
int	getKeySize() Get the key size of the cipher these parameters are for.
String	toString()
