Yup, DES just doesn't cut it any more.  In fact, new encryption algorithms
are sometimes measured in DES units where a single DES unit represents the
amount of computation time required to break DES (and the ratings are always
greater than 1!).  The newest algorithms are several orders of magnitude
more difficult to break than DES.
