Web1 Introduction. Random numbers and randomization techniques are critical for modern-day cryptography. Random numbers are used to initialize key bits for secret- and public-key algorithms, seed pseudo-random number generators, provide challenges, nonces, padding bits, as well as initialization vectors in cryptographic primitives and protocols. 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. Apple OSes have switched to Fortuna since …
