"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. " - Cryptographic random number generators

In the discussion below, CSPRNG designs are divided into three classes: 1. those based on cryptographic primitives such as ciphers and cryptographic hashes, 2. those based upon mathematical problems thought to be hard, and 3. special-purpose designs. WebHowever, generally they are considerably slower (typically by a factor 2-10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.
