WebJul 19, 2016 · The output of AES is random and unpredictable, so within reasonable constraints, you can securely use to generate random numbers, where the key (of 128, 192, or 256 bits) is effectively used as your seed value, you encrypt a counter, and the ciphertext is your random stream. WebAug 6, 2016 · There is no known method to predict decay so, yes, that is by definition cryptographically secure. Such things are considered true randomness, as opposed to the pseudo-randomness that we generate with our pseudo-random number generators (algorithms). The caveat is that you have to use the true random source properly.
