Yes, of course. PRNG's are about producing random data from a seed. But /dev/random & /dev/urandom isn't just a PRNG.

Which is effectively what is going on with /dev/random & /dev/urandom
- tptacek 3y agoAt the point where you're simply equating /dev/random and /dev/urandom, you're no longer really disagreeing with anybody here. The only difference between the two is that /dev/random keeps a metric on how many bits its vended, and blocks waiting for rekeying when that metric gets too high. That's more or less a nonsensical thing to do.
- cbsmith 3y agoI'm definitely not saying what /dev/random does makes sense. ;-)
