java.lang.Object
  gnu.crypto.jce.spec.BlockCipherParameterSpec

All Implemented Interfaces:

java.security.spec.AlgorithmParameterSpec

public class BlockCipherParameterSpec

extends java.lang.Object

implements java.security.spec.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
