A function which generates random bytes. A function which generates random bytes.

Notes

A cryptographically strong random number generator will be used if available. Otherwise, Math.random will be used as a fallback for randomness.

The following RNGs are supported, listed in order of precedence:

window.crypto.getRandomValues
window.msCrypto.getRandomValues
`require('crypto').randomFillSync
`require('crypto').randomBytes
Math.random
