WebbIn computing, a hardware random number generator ( HRNG) or true random number generator ( TRNG) is a device that generates random numbers from a physical process, rather than by means of an algorithm. WebbThe TPM security chip that is available on all modern desktop systems has a hwrng. It is also fed into the entropy pool, but generally not credited entropy. You may use rng_core.default_quality=1000 on the kernel command line to change that, but note that this is a global setting affect all hwrngs. (Yeah, that’s weird.) tripmasters cts
