Huh?  He was talking about CRYPT(1), not CRYPT(3); to quote the SunOS 4.0
CRYPT(1) man page,

     crypt implements a  one-rotor  machine  designed  along  the
     lines  of  the  German Enigma, but with a 256-element rotor.
     Methods of attack on such machines are  widely  known,  thus
     crypt provides minimal security.

This is also correct for "crypt" in other UNIX systems.  It doesn't use
DES.
