I believe it's still DES based but has been "crippled" so that the Russkies
can't get a hold of DES technology :-(.

Different other "crypt".  There's the "crypt" routine, which is DES-based
(at least in pre-stupid-export-control UNIX and in domestic System V) and
the "crypt" command which is rotor-based (and has been cracked, but it's
*still* not available in international System V).
