Generate strong pseudo-random bytes.

This module is a simple wrapper around the Node.js core crypto.randomBytes API, with the following additions:

• A Promise interface for environments with promises.
• For Node.js versions that do not wait for the PRNG to be seeded, this module will wait a bit.

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ npm install random-bytes

var randomBytes = require('random-bytes')

Generates strong pseudo-random bytes. The size argument is a number indicating the number of bytes to generate.

randomBytes(12, function (error, bytes) { if (error) throw error // do something with the bytes })

Generates strong pseudo-random bytes and return a Promise. The size argument is a number indicating the number of bytes to generate.

Note: To use promises in Node.js prior to 0.12, promises must be "polyfilled" using global.Promise = require('bluebird').

randomBytes(18).then(function (string) { // do something with the string })

A synchronous version of above.

var bytes = randomBytes.sync(18)
