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. [1] Apple OSes have switched to Fortuna … WebJul 19, 2024 · The same CSPRNG algorithm is used for random and urandom: applications can use /dev/random and /dev/urandom interchangeably. Only one slight difference was maintained between /dev/random and /dev/urandom : /dev/random retains the ability to block during early system initialization (but not once the system is fully booted).
