Generate, import, and export PeerIDs, for use with [IPFS](https://github.com/ipfs/ipfs).

> A Peer ID is the SHA-256 [multihash](https://github.com/multiformats/multihash) of a public key.
>
> The public key is a base64 encoded string of a protobuf containing an RSA DER buffer. This uses a node buffer to pass the base64 encoded public key protobuf to the multihash for ID generation.

## Example

```js
var PeerId = require('peer-id')

PeerId.create({ bits: 1024 }, (err, id) => {
  console.log(JSON.stringify(id.toJSON(), null, 2)
})
```

```json
{
  "id": "Qma9T5YraSnpRDZqRR4krcSJabThc8nwZuJV3LercPHufi",
  "privKey": "CAAS4AQwggJcAgEAAoGBAMBgbIqyOL26oV3nGPBYrdpbv..",
  "pubKey": "CAASogEwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBAMBgbIqyOL26oV3nGPBYrdpbvzCY..."
}
```

## Installation

### npm

```sh
> npm i peer-id
```

## Setup

### Node.js

```js
var PeerId = require('peer-id')
```

### Browser: Browserify, Webpack, other bundlers

The code published to npm that gets loaded on require is in fact a ES5
transpiled version with the right shims added. This means that you can require
it and use with your favourite bundler without having to adjust asset management
process.

```js
var PeerId = require('peer-id')
```

### Browser: `<script>` Tag

Loading this module through a script tag will make the `PeerId` obj available in
the global namespace.

```html
<script src="https://unpkg.com/peer-id/dist/index.min.js"></script>
<!-- OR -->
<script src="https://unpkg.com/peer-id/dist/index.js"></script>
```
