to a hardware device does increase complexity, and
thus cost at the expense of extensibility (new algorithms come
along periodically).  The cost of verifying crypto is a bit higher
as it is very important to get correct when baking into gates.

As I mentioned earlier in the thread, all modern CPUs have
support for the standard algorithms in their instruction
set (optionally fused out for export).

Yes.
