- * These routines do some reordering of the supplied data before
- * calling engine() to do the main work.
- *
- * The reordering seems similar to that done by the initial stages of
- * the DES algorithm, in that it looks like it's just been done to
- * try and make software decoding slower. I'm not sure that it
- * actually adds anything to the security.
- *
- * The nature of the shuffling is that the bits of the supplied
- * parameter 'varient' are reorganised (and some inverted), and
- * the bytes of the parameter 'challenge' are reorganised.
- *
- * The reorganisation in each routine is different, and the first
- * (CryptKey1) does not bother of play with the 'varient' parameter.
- *
- * Since this code is only run once per disk change, I've made the
- * code table driven in order to improve readability.
- *
- * Since these routines are so similar to each other, one could even
- * abstract them all to one routine supplied a parameter determining
- * the nature of the reordering it has to do.
