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.
``sh`
$ npm install random-bytes
`js`
var randomBytes = require('random-bytes')
Generates strong pseudo-random bytes. The size argument is a number indicating
the number of bytes to generate.
`js`
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').
`js`
randomBytes(18).then(function (string) {
// do something with the string
})
A synchronous version of above.
`js``
var bytes = randomBytes.sync(18)
