56-bit DES encryption has been broken with brute force in hours using
non-classified special purpose equipment. It's a reasonable guess that
DES is an open book to NSA and other agencies with similar computing
power available. Worse, communication between an HP3000 and a terminal is
highly stylized ("HELLO ...", "RUN ...."), making attacks that much
easier. It's likely that general-purpose equipment two years from now
will be able to achieve solutions in hours or days, and unless passwords
are changed on cycles shorter than the average solution time, cracking a
single key is all that's necessary to obtain system access.

It's worth looking at GnuPG (<http://www.gnupg.org>) to see if that can
be made to work.
