Want a FIPS 140-2 RNG? Look at the universe. The cosmic background radiation bathes Earth in enough random numbers to encrypt everything forever. Using the cosmic background radiation – the "echo of the Big Bang" – as a random number generation isn't a new idea, but a couple of scientists have run the slide-rule over measurements of the CMB power spectrum and reckon it offers a random number space big enough to beat any current computer.
Not in terms of protecting messages against any current decryption possibility: the CMB's power spectrum offers a key space "too large for the encryption/decryption capacities of present computer systems". A straightforward terrestrial radio telescope, this Arxiv paper states, should be good enough to make "astrophysical entropy sources accessible on comparatively modest budgets".

Please connect a 1 billion dollar telescope to the USB port to activate /dev/cmb. The upcoming Giant Magellan Telescope will serve nicely.

Radio telescope not needed; you can observe cosmic rays well enough using a USB webcam in a light-proof box. [archive.org]
