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.

## Installation

```sh
$ npm install random-bytes
```

## API

```js
var randomBytes = require('random-bytes')
```

### randomBytes(size, callback)

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
})
```

### randomBytes(size)

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
})
```

### randomBytes.sync(size)

A synchronous version of above.

```js
var bytes = randomBytes.sync(18)
```
