WebCryptographically Secure Pseudo-Random Number Generators (CSPRNG) are designed to produce a much higher quality of randomness (more strictly, a greater amount of entropy), making them safe to use for security-sensitive functionality. WebThere are two types of PRNGs: statistical and cryptographic. Statistical PRNGs provide useful statistical properties, but their output is highly predictable and forms an easy to reproduce numeric stream that is unsuitable for use in cases where security depends on generated values being unpredictable. 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] portable hgv wheel wash

"WebInitialization vectors must be chosen appropriate for the mode of operation. For many modes, this means using a CSPRNG (cryptographically secure pseudo random number generator). For modes that require a nonce, then the initialization vector (IV) does not need a CSPRNG. In all cases, the IV should never be used twice for a fixed key. " - Cryptographically secure prng
