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 … WebNov 6, 2024 · As we’ve discussed in the past, cryptography relies on the ability to generate random numbers that are both unpredictable and kept secret from any adversary. But “random” is a pretty tricky term; it’s used in many different fields to mean slightly different things. And like all of those fields, its use in cryptography is very precise.
