right, and to some degree we cater for these people.

Which is another reason why I continue with the arrgh board: To address
people who are more comfortable with MCUS and only need a HWRNG/TRNG anyway.

For those who need a full-blown HSM however, there are only two options:
Trust somebody (us or whoever) with doing and checking the FPGA part, or
learning about FPGAs so they can check themselves.

On the other hand we do make things much harder for the FPGA people if
we follow that path; and we expect them to be or make themselves
familiar with MCUs.

There's really no one-size-fits-all solution to this.


Cheers,
