Password Generator is app for generating secure passwords using cryptographically secure pseudo-random number generator. 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…
WebJul 11, 2014 · A secure block cipher can be converted into a CSPRNG by running it in counter mode. This is done by choosing a random key and encrypting a 0, then encrypting a 1, then encrypting a 2, etc. The counter can also be started at an arbitrary number other than zero. WebBlum-Blum-Shub is a PRNG algorithm that is considered cryptographically secure. Its base is based on prime numbers. Park-Miller generator: 1988 S. K. Park and K. W. Miller A specific implementation of a Lehmer generator, widely used because it is included in C++ as the function minstd_rand0 from C++11 onwards. ACORN generator (discovered 1984) 1989
A cryptographically secure pseudorandom number generator (CSPRNG) or cryptographic pseudorandom number generator (CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also loosely known as a cryptographic random … See more The requirements of an ordinary PRNG are also satisfied by a cryptographically secure PRNG, but the reverse is not true.
