 # Description

-An IPFS Peer Id is based on a sha256 hash of the peer public key, using [multihash](https://github.com/jbenet/multihash)
+Generate, import, and export PeerIDs, for use with [IPFS](https://github.com/ipfs/ipfs).

-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. 
+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.

-# Usage
-
-### In Node.js through npm
-
-```bash
-$ npm install --save peer-id
-```
-
-```javascript
-var PeerId = require('peer-id')
-```
-
-### In the Browser through browserify
-
-Same as in Node.js, you just have to [browserify](https://github.com/substack/node-browserify) the code before serving it. See the browserify repo for how to do that.
-
-### In the Browser through `<script>` tag
-
-Make the [peer-id.min.js](/dist/peer-id.min.js) available through your server and load it using a normal `<script>` tag, this will export the `peerId` constructor on the `window` object, such that:
+# Example

 ```JavaScript
-var PeerId = window.PeerId
+const PeerId = require('peer-id')
+
+const id = await PeerId.create({ bits: 1024, keyType: 'rsa' })
+console.log(JSON.stringify(id.toJSON(), null, 2))
 ```

-#### Gotchas
-
-You will need to use Node.js `Buffer` API compatible, if you are running inside the browser, you can access it by `PeerId.Buffer` or you can install Feross's [Buffer](https://github.com/feross/buffer).
-
-### Creating a new Id
-
-```
-var PeerId = require('ipfs-peer')
-
-// Create a new Id
-var id = PeerId.create()
-
-// Recreate an Id from Hex string
-var id = PeerId.createFromHexString(str)
-
-// Recreate an Id from a Buffer
-var id = PeerId.createFromBytes(buf)
-
-// Recreate an B58 String
-var id = PeerId.createFromB58String(str)
-
-// Recreate from a Public Key
-var id = PeerId.createFromPubKey(pubKey)
-
-// Recreate from a Private Key
-var id = PeerId.createFromPrivKey(privKey)
+```bash
+{
+  "id": "Qma9T5YraSnpRDZqRR4krcSJabThc8nwZuJV3LercPHufi",
+  "privKey": "CAAS4AQwggJcAgEAAoGBAMBgbIqyOL26oV3nGPBYrdpbv..",
+  "pubKey": "CAASogEwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBAMBgbIqyOL26oV3nGPBYrdpbvzCY..."
+}
 ```

-### Exporting an Id
+# Installation

-```
-// Print friendly format
-id.toPrint() // returns an object with id, privKey and pubKey in hex format
+## npm

-// Export to an hex string
-id.toHexString()
-
-// Export to Buffer
-id.toBytes() (same as id.id)
-
-// Export to a B58 string
-id.toB58String()
+```sh
+> npm i peer-id
 ```

-### Id format
+# Setup
+
+## Node.js
+
+```js
+const 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
+const 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>
+```
+
+# API
+
+```js
+const PeerId = require('peer-id')
+```
+
+## Create
+
+### `new PeerId(id[, privKey, pubKey])`
+
+- `id: Buffer` - The multihash of the public key as `Buffer`
+- `privKey: RsaPrivateKey` - The private key
+- `pubKey: RsaPublicKey` - The public key
+
+The key format is detailed in [libp2p-crypto](https://github.com/libp2p/js-libp2p-crypto).
+
+### `create([opts])`
+
+Generates a new Peer ID, complete with public/private keypair.
+
+- `opts: Object`: Default: `{bits: 2048, keyType: 'rsa'}`
+
+Returns `Promise<PeerId>`.
+
+## Import
+
+### `createFromHexString(str)`
+
+Creates a Peer ID from hex string representing the key's multihash.
+
+Returns `PeerId.
+
+### `createFromBytes(buf)`
+
+Creates a Peer ID from a buffer representing the key's multihash.
+
+Returns `PeerId`.
+
+### `createFromCID(cid)`
+
+- `cid: CID|String|Buffer` - The multihash encoded as [CID](https://github.com/ipld/js-cid) (object, `String` or `Buffer`)
+
+Creates a Peer ID from a CID representation of the key's multihash ([RFC 0001](https://github.com/libp2p/specs/blob/master/RFC/0001-text-peerid-cid.md)).
+
+Returns `PeerId`.
+
+### `createFromB58String(str)`
+
+Creates a Peer ID from a Base58 string representing the key's multihash.
+
+Returns `PeerId`.
+
+### `createFromPubKey(pubKey)`
+
+- `publicKey: Buffer`
+
+Creates a Peer ID from a buffer containing a public key.
+
+Returns `Promise<PeerId>`.
+
+### `createFromPrivKey(privKey)`
+
+- `privKey: Buffer`
+
+Creates a Peer ID from a buffer containing a private key.
+
+Returns `Promise<PeerId>`.
+
+### `createFromJSON(obj)`
+
+- `obj.id: String` - The multihash encoded in `base58`
+- `obj.pubKey: String` - The public key in protobuf format, encoded in `base64`
+- `obj.privKey: String` - The private key in protobuf format, encoded in `base64`
+
+Returns `Promise<PeerId>`.
+
+### `createFromProtobuf(buf)`
+
+`buf` is a protocol-buffers encoded PeerId (see `marshal()`)
+
+## Export
+
+### `toHexString()`
+
+Returns the Peer ID's `id` as a hex string.

 ```
-id.pubKey   // Buffer containing the Public Key
-id.privKey  // Buffer containing the Private Key
-id.id       // Buffer containing the multihash
+1220d6243998f2fc56343ad7ed0342ab7886a4eb18d736f1b67d44b37fcc81e0f39f
 ```
+
+### `toBytes()`
+
+Returns the Peer ID's `id` as a buffer.
+
+```
+<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>
+```
+
+
+### `toString()`
+
+Returns the Peer ID's `id` as a self-describing CIDv1 in Base32 ([RFC 0001](https://github.com/libp2p/specs/blob/master/RFC/0001-text-peerid-cid.md))
+
+```
+bafzbeigweq4zr4x4ky2dvv7nanbkw6egutvrrvzw6g3h2rftp7gidyhtt4
+```
+
+### `toB58String()`

+Returns an `obj` of the form
+
+- `obj.id: String` - The multihash encoded in `base58`
+- `obj.pubKey: String` - The public key in protobuf format, encoded in 'base64'
+- `obj.privKey: String` - The private key in protobuf format, encoded in 'base 64'
+
+### `marshal(excludePrivateKey)`
+
+Returns a protocol-buffers encoded version of the id, public key and, if `excludePrivateKey` is not set, the private key.
+
+### `marshalPubKey()`
+
+Returns a protobuf of just the public key, compatible with `libp2p-crypto` (unlike `marshal` above).
+
+For example:
+```js
+const crypto = require('libp2p-crypto')
+
+PeerId.create({ bits: 256, keyType: 'ed25519' }).then( pid => {
+  let pk = crypto.keys.unmarshalPublicKey(pid.marshalPubKey())
+  // your code here
+}
+```
+
+### `toPrint()`
+
+Returns the Peer ID as a printable string without the `Qm` prefix.
+
+Example: `<peer.ID xxxxxx>`
+
+### `equals(id)`
+
+Returns `true` if the given PeerId is equal to the current instance.
+
+- `id` can be a PeerId or a Buffer containing the id
+
+### `isEqual(id)`
+**Deprecation Notice**: Use [`equals`](#equalsid), `isEqual` will be removed in 0.14.0.
+
+- `id` can be a PeerId or a Buffer containing the id
