Just to make this clear. For the type of product we're discussing, there
is no problem whatsoever with using crypto systems in the UK.
The only time that GCHQ (UK equiv of NSA) get interested is when
you try and export the product and it uses some algorithm that
they've never heard of.
This information is from first hand experience. I was involved in a publicly
available crypto modem 10 years ago. The spooks (after 3 months with 2 modems
and the source code) eventually admitted it was based on no known algorithm.
(And they missed at least one of the twists in it :-)
