WebMar 8, 2024 · It pulls randomness/entropy from many different sources, only one of which may be the seed. It is cryptographically secure because you cannot reset it back to a previous state, which means you cannot get the same sequence of outputs from it. WebIdeally, the output of any encryption algorithm, will appear very nearly random. This also requires that the key utilized in that algorithm be nearly random. This brings us to pseudo-random number generators. They are called “pseudo” because the output is not truly completely random.
