i would agree.  if the government "pushes" a particular encryption
scheme, it's probably because they're able to crack it.

DES is certainly good enough to stop casual snooping, but i wouldn't
trust it if *i* were running a big corporation.  it does make me wonder
how fast the NSA gang can crack DES stuff, though.  seems like i 
remember reading somewhere that one of the criticisms of DES is
that nobody's quite sure where the S-boxes came from...furthermore,
they're non-random, leaving a possible trapdoor somewhere.  if *that*
was true, no wonder NSA wants us all using DES!

yep.
