WebIn computer science random numbers usually come from a pseudo-random number generators (PRNG), initialized by some unpredictable initial randomness (entropy). In cryptography secure PRNGs are used, known as CSPRNG, which typically combined entropy with PRNG and other techniques to make the generated randomness unpredictable. WebTo generate a random number, use one of the RandomNumberGenerator static methods instead. Implements a cryptographic Random Number Generator (RNG) using the implementation provided by the cryptographic service provider (CSP). This class cannot be inherited.
