There's a pretty decent password cracker in the COPS package (look in the
FastDES directory).  It's available for anon-FTP from uxc.cso.uiuc.edu in
pub/cops.tar.Z .

On a IBM RS6000/540, it runs at 1.64ms per read/encrypt/compare iteration.
It takes 40 seconds per entry to cycle through /usr/dict/words (~24K entries)
and just over 7 minutes per entry to cycle through a wordlist from the OED2
(252K entries).

Btw, the on-line OED2 (750 Mbytes) plus the per-word index (460 Mbytes) is
leased from Oxford University Press.  The educational license is $10K/5 years.
Contact newoed@watsol.waterloo.edu for more information.
