Crypto random int
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. WebJan 9, 2024 · Go crypto-secure random values Go provides cryptographically secure pseudorandom number generator in the standard library package crypto/rand. While math/random is much faster, crypto/rand is suited for programs where security is paramount. For instance, when generating strong passwords, CSRF tokens, or session keys.
