WebApr 14, 2024 · The NIST SP 800-90 series provides guidance on the generation of high-quality random bits for cryptographic and non-cryptographic use. The security of a random number generator depends on the unpredictability of its outputs, which can be measured in terms of entropy. The NIST SP 800-90 series uses min-entropy to measure entropy. WebFeb 5, 2024 · Random numbers have a large application (especially in cryptography). About hashes: Hashes are deterministic. That means that some input always has exactly the same hash-value. No matter when, where or anything, an identical hashing-algorithm creates always the same hash-value for an identical input.
