Field Summary final protected static  int BLOCK_SIZE      Constructor Summary public   DESEngine()      standard constructor. Method Summary protected  void desFunc(int[] wKey, byte[] in, int inOff, byte[] out, int outOff)      the DES engine. protected  int[] generateWorkingKey(boolean encrypting, byte[] key)      generate an integer based working key based on our secret key and what we processing we are planning to do. public  String getAlgorithmName()      public  int getBlockSize()      public  void init(boolean encrypting, CipherParameters params)      initialise a DES cipher. public  int processBlock(byte[] in, int inOff, byte[] out, int outOff)      public  void reset()      Field Detail BLOCK_SIZE final protected static int BLOCK_SIZE(Code) Constructor Detail DESEngine public DESEngine()(Code) standard constructor. Method Detail desFunc protected void desFunc(int[] wKey, byte[] in, int inOff, byte[] out, int outOff)(Code) the DES engine. generateWorkingKey protected int[] generateWorkingKey(boolean encrypting, byte[] key)(Code) generate an integer based working key based on our secret key and what we processing we are planning to do. Acknowledgements for this routine go to James Gillogly & Phil Karn. (whoever, and wherever they are!). getAlgorithmName public String getAlgorithmName()(Code) getBlockSize public int getBlockSize()(Code) init public void init(boolean encrypting, CipherParameters params)(Code) initialise a DES cipher. Parameters:   encrypting - whether or not we are for encryption. Parameters:   params - the parameters required to set up the cipher. exception:   IllegalArgumentException - if the params argument isinappropriate. processBlock public int processBlock(byte[] in, int inOff, byte[] out, int outOff)(Code) reset public void reset()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
