Some of us are capable of building crypto out of non-CPU devices (as
in MSI).
I'm also toying around with the idea of building an electro-mechanical
implementation of DES as a project for my new milling machine.
Having worked on a KW-26/TSEC in the mid '70s, It would be a lot harder
to keep someone from building crypto that you think. These were based
on saturated core transformers driven by tube pulse drivers. The only
semiconductors in them were signal diodes. Of course, the MILSTD-188B
interface line drivers had some transistors as well. The tubes could
have FET transistors substituted. Working in 3D, I think you could implement
IDEA in around a cubic foot...
