| Method Detail |
public 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.public java.lang.String getAlgorithmName()
public byte returnByte(byte in)
in - the byte to be processed.
public 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 stars at.
DataLengthException - if the output buffer is too small.public void reset()
