WebIt has to pass certain statistical randomness tests to prove unpredictability. An attacker must not be able to predict the outputs of the CSPRNG even if they have partial access to the program. Like a PRNG, a CSPRNG needs random data (the cryptographic seed) as a starting point from which to produce more random data. WebAs mentioned earlier, secure web transactions are just one application of encryption. Randomness is also important in establishing secure wireless communication, generating nonces, one-time pads, and so on. For a random number to be useful in security, it needs to be what we call cryptographically secure.
