Initialise the cipher. |
void |
processBytes(byte[] in,
int inOff,
int len,
byte[] out,
int outOff)
process a block of bytes from in putting the result into out. |

| Method Detail |
|---|
void init(boolean forEncryption,
CipherParameters params)
throws java.lang.IllegalArgumentException
forEncryption - if true the cipher is initialised for
encryption, if false for decryption.params - the key and other data required by the cipher.
java.lang.IllegalArgumentException - if the params argument is
inappropriate.java.lang.String getAlgorithmName()
byte returnByte(byte in)
in - the byte to be processed.
void processBytes(byte[] in,
int inOff,
int len,
byte[] out,
int outOff)
throws DataLengthException
in - the input byte array.inOff - the offset into the in array where the data to be processed starts.len - the number of bytes to be processed.out - the output buffer the processed bytes go into.outOff - the offset into the output byte array the processed data starts at.
DataLengthException - if the output buffer is too small.void reset()
