A cryptographically secure pseudorandom number generator (CSPRNG) or cryptographic pseudorandom number generator (CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also loosely known as a cryptographic random number generator (CRNG) (see Random number generation § "True" vs. pseudo-random numbers). WebCryptographically secure generators are generators that are strongly believed to be very difficult to predict, in part because they have received considerable scrutiny from the cryptographic community and no one has found a good way to break them.
