Cryptographic random
WebFortuna is a cryptographically secure pseudorandom number generator (PRNG) devised by Bruce Schneier and Niels Ferguson and published in 2003. It is named after Fortuna, the Roman goddess of chance. FreeBSD uses Fortuna for /dev/random and /dev/urandom is symbolically linked to it since FreeBSD 11.

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. WebCryptographic PRNGs address this problem by generating output that is more difficult to predict. For a value to be cryptographically secure, it must be impossible or highly …
