Class RijndaelEngine
java.lang.Object
org.bouncycastle.crypto.engines.RijndaelEngine
- BlockCipher
public class RijndaelEngine
extends java.lang.Object
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.
RijndaelEngine() - default constructor - 128 bit block size.

RijndaelEngine(int blockBits) - basic constructor - set the cipher up for a given blocksize

RijndaelEngine
public RijndaelEngine()
default constructor - 128 bit block size.
RijndaelEngine
public RijndaelEngine(int blockBits)
basic constructor - set the cipher up for a given blocksize
blockBits
- the blocksize in bits, must be 128, 192, or 256.
init
public void init(boolean forEncryption,
CipherParameters params)
initialise a Rijndael cipher.
- init in interface BlockCipher
forEncryption
- whether or not we are for encryption.params
- the parameters required to set up the cipher.
processBlock
public int processBlock(byte[] in,
int inOff,
byte[] out,
int outOff)
- processBlock in interface BlockCipher
