Cryptographic random bytes and u64.

Introduction

Cryptographic random bytes and u64. Import std/crypto/random to bind the module as random. Call free functions as random.name(...). Struct methods use a receiver value.

/ std/crypto/random

This page is the package reference for std/crypto/random. Private helpers used only by co-located tests are not listed.

Functions

Free functions on random. Each function has a short description, an example, then parameters and return shape.

fill

Fills n cryptographically secure random bytes. Call form: random.fill(n).

/ std/crypto/random

$ b = random.fill(16)

Parameters: n: number of bytes. Returns: n random bytes.

u64

Returns a cryptographically secure random u64. Call form: random.u64().

/ std/crypto/random

$ n = random.u64()

Parameters: No parameters. Returns: Integer random value.
