crypt.random

Returns a string of size random bytes.

crypt.random(size: number): string

Each call returns a different result. For random bytes already Base64-encoded use crypt.generatebytes; for an AES key use crypt.generatekey.

Most commonly used as a raw-randomness source for tokens, salts, and nonces.
