mdb: convenient 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!).

Parameters:
  key - the parameters required to set up the cipher.
exception:
  IllegalArgumentException - if the params argument isinappropriate.



processBlock
