PRNG needs entropy, but it doesn't consume it. You don't need to feed entropy into it continuously.

- msla 7y ago> PRNG needs entropy, but it doesn't consume it. You don't need to feed entropy into it continuously. In the extreme case, this means you can run a PRNG with a fixed seed indefinitely, which is definitely wrong because such a PRNG will necessarily loop. That might not be feasible to exploit, however.
- stouset 7y ago> such a PRNG will necessarily loop Given infinite time, energy, and computing power, yes. Given computers made out matter and running on energy for use by meat-based intelligences, no. This is really analogous to saying "technically a 256-bit encryption key is brute-forceable". In fact, this is so close to being the actual underlying situation it's barely even an analogy.
