Cryptography random number generator
WebOct 12, 2024 · The data produced by this function is cryptographically random. It is far more random than the data generated by the typical random number generator such as the one shipped with your C compiler. This function is often used to generate random initialization vectors and salt values. Software random number generators work in fundamentally the … WebWhen generating random data for use in cryptographic operations, such as an initialization vector for encryption in CBC mode, you do not want to use the standard random module APIs. This is because they do not provide a cryptographically secure random number generator, which can result in major security issues depending on the algorithms in use.
