WebIf you want a lot of pseudorandomness with a very high bandwidth, you should look at specialized stream ciphers like these ones (a stream cipher can be turned into a PRNG by making it encrypt a long sequence of zeros). WebMath::Random::Secure is intended to provide a cryptographically-secure replacement for Perl's built-in rand function. "Crytographically secure", in this case, means that: nobody can guess the future number, there are so many possible seeds that it would take millenia for an attacker to try them all. ...

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. church with jesse lee petersonWebTo generate a cryptographically secure random number, such as one that's suitable for creating a random password, use the RNGCryptoServiceProvider class or derive a class … church with crooked spire chesterfield

"A PRNG suitable for cryptographic applications is called a cryptographically-secure PRNG (CSPRNG). A requirement for a CSPRNG is that an adversary not knowing the seed has only negligible advantage in distinguishing the generator's output sequence from a random sequence. In other words, while a PRNG is only required to pass certain statistical tests, a CSPRNG must pass all statistical tests that are restricted to polynomial time in the size of the seed. Though a pr… " - Cryptographically secure prng
