Class RijndaelEngine

public class RijndaelEngine extends Object implements BlockCipher

an implementation of Rijndael, based on the documentation and reference implementation by Paulo Barreto, Vincent Rijmen, for v2.0 August '99.

Note: this implementation is based on information prior to final NIST publication.

Constructor Summary
	RijndaelEngine() default constructor - 128 bit block size.
	RijndaelEngine(int blockBits) basic constructor - set the cipher up for a given blocksize

Method Summary
String	getAlgorithmName()
int	getBlockSize()
void	init(boolean forEncryption, CipherParameters params) initialise a Rijndael cipher.
int	processBlock(byte[] in, int inOff, byte[] out, int outOff)
void	reset()

Constructor Detail

public RijndaelEngine()

default constructor - 128 bit block size.

public RijndaelEngine(int blockBits)

basic constructor - set the cipher up for a given blocksize

Parameters: blockBits the blocksize in bits, must be 128, 192, or 256.

public String getAlgorithmName()

public int getBlockSize()

public void init(boolean forEncryption, CipherParameters params)

initialise a Rijndael cipher.

Parameters: forEncryption whether or not we are for encryption. params the parameters required to set up the cipher.

Throws: IllegalArgumentException if the params argument is inappropriate.

public int processBlock(byte[] in, int inOff, byte[] out, int outOff)

public void reset()
