Method Detail

desFunc

protected void desFunc(int[] wKey, byte[] in, int inOff, byte[] out, int outOff)

the DES engine.

generateWorkingKey

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. Acknowledgements for this routine go to James Gillogly & Phil Karn. (whoever, and wherever they are!).
