Hardware random number generator

[Crivens]

I believe that your salaries there have either increased significantly, or Boeings have become much cheaper...

I think the latter. You can get plane parts for free these days (or so I was told).

Does it work on FreeBSD? If not, why are you posting here?

It can work on FreeBSD, just using FTDI USB chip. And freeBSD can support pyftdi

Assuming you have enough of a driver to read from your hardware random number device, could it be as simple as starting a task early on that uses dd to copy from the device to /dev/random? I'm a little shaky on the details of FreeBSD I/O yet, so this may be crazy, but it would seem like the write would block with FreeBSD didn't want any more entropy, and the read would block when the hardware device didn't have any more to give at the moment.

Random number generation: An illustrated primer

Last week we learned (from two different sources!) that certain RSA implementations don’t properly seed their random number generators before generating keys. One practical upshot is that a n…
