 # API

-```js
-const PeerId = require('peer-id')
-```
-
-## Create
-
-### PeerId.create()
-
-Generates a new Peer ID, complete with public/private keypair. A Peer ID has the
-following properties:
-
- `pubKey` - Buffer containing the public key bytes
- `privKey` - Buffer containing the private key bytes
- `id` - Buffer containing the multihash bytes
-
-## Import
-
-### PeerId.createFromHexString(str)
-
-Creates a Peer ID from hex string representing the key's multihash.
-
-### PeerId.createFromBytes(buf)
-
-Creates a Peer ID from a buffer representing the key's multihash.
-
-### PeerId.createFromB58String(str)
-Creates a Peer ID from a Base58 string representing the key's multihash.
-
-### PeerId.createFromPubKey(pubKey)
-
-Creates a Peer ID from a buffer containing a public key.
-
-### PeerId.createFromPrivKey(privKey)
-
-Creates a Peer ID from a buffer containing a private key.
-
-## Export
-
-### id.toPrint()
-
-Returns an object with the ID's properties in hex format:
-```js
-{
-  id: 'QmckZzdVd72h9QUFuJJpQqhsZqGLwjhh81qSvZ9BhB2FQi',
-  privKey: '080012a609308204a20201000282010100a608889914da08959d3a3db0734cee812c96...',

-}
-```
-
-### id.toHexString()
-
-Returns the Peer ID's `id` as a hex string.
-
-```js
-1220d6243998f2fc56343ad7ed0342ab7886a4eb18d736f1b67d44b37fcc81e0f39f```
-
-### id.toBytes()
-
-Returns the Peer ID's `id` as a buffer.
-
-
-```js
-<Buffer 12 20 d6 24 39 98 f2 fc 56 34 3a d7 ed 03 42 ab 78 86 a4 eb 18 d7 36 f1 b6 7d 44 b3 7f cc 81 e0 f3 9f>
-```
-
-### id.toB58String()
-
-Returns the Peer ID's `id` as a base58 string.

+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)
+})

+  "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.
