java.lang.Objectorg.bouncycastle.crypto.engines.RijndaelEngine
public class RijndaelEngine
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 | |
|---|---|
java.lang.String |
getAlgorithmName()
Return the name of the algorithm the cipher implements. |
int |
getBlockSize()
Return the block size for this cipher (in bytes). |
void |
init(boolean forEncryption,
CipherParameters params)
initialise a Rijndael cipher. |
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. |
void |
reset()
