Since the Zymkey has a True Random Number Generator how might I leverage it as a block device similar to /dev/urandom? I know there are Python and C-based APIs for generating random data but a lot of common software uses the block devices in /dev. Perhaps there’s a way to direct /dev/urandom to use the Zymbit TRNG?
The best way to do this is to use the APIs directly in your code rather than try and do some sort of shim thing. I don’t there’s a really clean way to do what you want to do.
