It's a shame http://entropykey.co.uk is no longer in business. I was able to
procure 5 entropy keys just before they folded, and they're awesome. All the
hardware specifications were open, as well as the userspace software. I ended
up creating an entropy server with these keys, of which I feed all my VM
entropy pools with. You can see it at http://hundun.ae.st. I'm currently
working on a program to feed the random data found from an RTL-SDR dongle into
the entropy pool. Then just tune to an empty frequency, and let atmospheric
At any event, I'm in agreeance: hardware true random number generators > *.
