Just a quick note about a service I discovered today: Quantum Random Bit Generator Service http://random.irb.hr/.
It's basically a random number generation service accessible online. So you just register an account, download the command line binary and get up to 100MB of true randomness per day for free.
$ ./qrand -u julien -p secretpassword -y -c 1000 -o test Downloaded and saved 1.95 KiB (100.00% of requested) in 0.282 sec (0.007 MiB/s). julien@arael:~/Downloads/QRBG QRand Utility/bin$ file test test: data julien@arael:~/Downloads/QRBG QRand Utility/bin$ cat test [.........bunch of random junk........]
What is really cool, is that you will never get that quality of randomness on your operating system.
Big downside: no SSL. So you have no way to check if bigs are modified along the way...
But that could still be useful for diskless systems. I'm sure there is a way to plug that into /dev/random. Just give me a few days ;)
