> 1) Get 8 bytes from /dev/urandom. (Just for sure.) Put them into the You probably know this if you use it, but /dev/random is the most "random" one, as it always uses system entropy, rather than falling back on an algorithm to generate more bits than are available in the pool. Since you only need 8 bytes of random seed (and if you don't need to generate many OTPs at a time...) it might be worth using it instead. Can't help you on the entropy quality though.
