yea, that is what I was referring to. decrypting a unix password is impossible
(even if you know the key word the particuliar unix bases it's encryption off
of). But people claim to be able too, *laugh*. My advisor would sure like to
meet them (he has 2 phd's, one from MIT), for he is unable to crack unix
passwords. (he worked for Sun for 8 years). Anyway, back to the original
