Webb10 nov. 2015 · Protocols get one of the parties or both parties together to generate a new random number that is long enough to be unguessable and unique. 128 bits are enough, though TLS uses more. Then they use this number as a symmetric encryption key (technically, seed for KDF), which allows them to quickly encrypt a lot of data. Webb16 okt. 2024 · Cryptographically secure RNGs generate random numbers that pass statistical randomness tests, and are resilient against prediction attacks (e.g. it is statistically infeasible to predict the next number produced).
