rng-tools provide rngd and rngtest.

rngd supplies data from a hardware RNG to the kernel's entropy
pool. To ensure sufficient randomness, rngd verifies the RNGs data
using FIPS 140-1 / 140-2 randomness tests, before passing them to the
kernel.

rngtest is a standalone tool for running the FIPS tests over data.
