WebIn computer science random numbers usually come from a pseudo-random number generators (PRNG), initialized by some unpredictable initial randomness (entropy). In cryptography secure PRNGs are used, known as CSPRNG, which typically combined entropy with PRNG and other techniques to make the generated randomness unpredictable.
