WebbA random number generator, like the ones above, is a device that can generate one or many random numbers within a defined scope. Random number generators can be hardware based or pseudo-random number generators. Hardware based random-number generators can involve the use of a dice, a coin for flipping, or many other devices. 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.
