Get random byte

Get a single, cryptographically strong, random byte.

This module uses an internal cache to minimize calls against the crypto backend. When the cache is empty, a large number of bytes is requested and handed out one by one. The perfomance benefits of this can be seen in this jsPerf test case.

Installation

npm install --save get-random-byte

Usage

const getRandomByte = require('get-random-byte')

console.log(getRandomByte())
//=> 112

console.log(getRandomByte())
//=> 143

console.log(getRandomByte())
//=> 205

API
