WebA cryptographically secure pseudorandom number generator, or CSPRNG, is a PRNG that meets more stringent standards, making it safer to use for cryptography. A CSPRNG meets two requirements that PRNGs may not necessarily meet: It has to pass certain statistical randomness tests to prove unpredictability.
