Avalanche noise RNG for one-time pad use I came across this little HRNG widget and was really intrigued as I have been looking for a decent but afordable source for truly random bits to use in a one-time pad.

The question is, would a HRNG like this one generate bits with sufficent randomness to provide the perfect secrecy one-time pads are known for? Such a design is of course slightly less random than a quantum RNG using decaying radioactive materials, but is the output random enough to be relied on?

If yes, would XORing the output bits with the plaintext be enough?
If this is a good HRNG (look for security reviews) I suppose yes. But it would be excruciatingly slow (HRNG's are not known to be fast, generally you use them to get 256-512 entropy bits to seed a PRNG and go with that) and you still have the key exchange + reuse OTP problem.

Note this tool apparently integrates itself with the Linux entropy pool, so I'm not sure you can actually access its raw output directly without it getting mixed with the rest. Perhaps there is an API for that. Using the Linux pool also means you will starve the system from entropy as your program eats it all to create a one-time pad... probably not a good idea :)

Remember you still need integrity checking.
