It would seem that to make the algorithm public necessarily leaves you
open to somebody building a brute force machine. Even if you control
the supply of the chips ("I think we should reject Mr.Rutenberg's order
for 10,000 chips") the people who have the capability to build such a
machine could also (easily) make their own chips to do it.

p.s. Speaking of which, does anyone know of any DES chips designed
outside of the US, or even outside of COCOM control. Just curious.
