WebApr 13, 2024 · Random numbers are a primitive for cryptographic operations. They are used frequently, from generating asymmetric and symmetric keys, to initialization vectors, salts and nonces. The library abstracts them with the RandomNumberGeneratorbase class and its derivatives. Some of the generators are cryptographically secure, while others are not. Webcrypto/rand implements a cryptographically secure pseudo-random number generator with a limited interface. The two packages can be combined by calling rand.New in package math/rand with a source that gets its data from crypto/rand.
