#### Setup with Keychain
|
||||
|
||||
Libp2p allows you to setup a secure keychain to manage your keys. The keychain configuration object should have the following properties:
|
||||
|
||||
| Name | Type | Description |
|
||||
|------|------|-------------|
|
||||
| pass | `string` | Passphrase to use in the keychain (minimum of 20 characters). |
|
||||
| datastore | `object` | must implement [ipfs/interface-datastore](https://github.com/ipfs/interface-datastore) |
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const TCP = require('libp2p-tcp')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
const SECIO = require('libp2p-secio')
|
||||
const LevelStore = require('datastore-level')
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|

transport: [TCP],

#### Configuring Dialing
|
||||
|
||||
Dialing in libp2p can be configured to limit the rate of dialing, and how long dials are allowed to take. The dialer configuration object should have the following properties:
|
||||
|
||||
| Name | Type | Description |
|
||||
|------|------|-------------|
|
||||
| maxParallelDials | `number` | How many multiaddrs we can dial in parallel. |
|
||||
| maxDialsPerPeer | `number` | How many multiaddrs we can dial per peer, in parallel. |

||||
| dialTimeout | `number` | Second dial timeout per peer in ms. |

|
||||
#### Configuring Transport Manager
|
||||
|
||||
The Transport Manager is responsible for managing the libp2p transports life cycle. This includes starting listeners for the provided listen addresses, closing these listeners and dialing using the provided transports. By default, if a libp2p node has a list of multiaddrs for listenning on and there are no valid transports for those multiaddrs, libp2p will throw an error on startup and shutdown. However, for some applications it is perfectly acceptable for libp2p nodes to start in dial only mode if all the listen multiaddrs failed. This error tolerance can be enabled as follows:
|
||||
|
||||
```js
|
||||
const Libp2p = require('libp2p')
|
||||
const TCP = require('libp2p-tcp')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
const SECIO = require('libp2p-secio')
|
||||
|
||||
const { FaultTolerance } = require('libp2p/src/transport-manager')}
|
||||
|
||||
const node = await Libp2p.create({
|
||||
modules: {
|
||||
transport: [TCP],
|
||||
streamMuxer: [MPLEX],
|
||||
connEncryption: [SECIO]
|
||||
},
|
||||
transportManager: {
|
||||
faultTolerance: FaultTolerance.NO_FATAL
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
#### Configuring Metrics
|
||||
|
||||
Metrics are disabled in libp2p by default. You can enable and configure them as follows:
|
||||
|
||||
| Name | Type | Description |
|
||||
|------|------|-------------|
|
||||
| enabled | `boolean` | Enabled metrics collection. |
|
||||
| computeThrottleMaxQueueSize | `number` | How many messages a stat will queue before processing. |
|
||||
| computeThrottleTimeout | `number` | Time in milliseconds a stat will wait, after the last item was added, before processing. |
|
||||
| movingAverageIntervals | `Array<number>` | The moving averages that will be computed. |
|
||||
| maxOldPeersRetention | `number` | How many disconnected peers we will retain stats for. |
|
||||
|
||||
The below configuration example shows how the metrics should be configured. Aside from enabled being `false` by default, the following default configuration options are listed below:

#### Configuring PeerStore
|
||||
|
||||
PeerStore persistence is disabled in libp2p by default. You can enable and configure it as follows. Aside from enabled being `false` by default, it will need an implementation of a [datastore](https://github.com/ipfs/interface-datastore). Take into consideration that using the memory datastore will be ineffective for persistence.
|
||||
|
||||
The threshold number represents the maximum number of "dirty peers" allowed in the PeerStore, i.e. peers that are not updated in the datastore. In this context, browser nodes should use a threshold of 1, since they might not "stop" properly in several scenarios and the PeerStore might end up with unflushed records when the window is closed.
|
||||
|
||||
| Name | Type | Description |
|
||||
|------|------|-------------|
|
||||
| persistence | `boolean` | Is persistence enabled. |
|
||||
| threshold | `number` | Number of dirty peers allowed. |
|
||||
|
||||
The below configuration example shows how the PeerStore should be configured. Aside from persistence being `false` by default, the following default configuration options are listed below:

Encryption is an important part of communicating on the libp2p network. Every connection must be encrypted to help ensure security for everyone. As such, Connection Encryption (Crypto) is a required component of libp2p.
|
||||

||||
There are a growing number of Crypto modules being developed for libp2p. As those are released they will be tracked in the [Connection Encryption section of the configuration readme](./CONFIGURATION.md#connection-encryption).

## PeerStore API
|
||||
|
||||
In `libp2p@0.27` we integrated the PeerStore (former [peer-book](https://github.com/libp2p/js-peer-book)) into the codebase. By that time, it was not documented in the [API DOC](../API.md) since it kept the same API as the `peer-book` and it was expected to be completelly rewritten in `libp2p@0.28`.
|
||||
|
||||
Moving towards a separation of concerns regarding known peers' data, as well as enabling PeerStore persistence, the PeerStore is now divided into four main components: `AddressBook`, `ProtoBook`, `KeyBook` and `MetadataBook`. This resulted in API changes in the PeerStore, since each type of peer data should now be added in an atomic fashion.
|
||||
|
||||
### Adding a Peer
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerId = ...
|
||||
const peerInfo = new PeerInfo(peerId)
|
||||
|
||||
peerInfo.protocols.add('/ping/1.0.0')
|
||||
peerInfo.protocols.add('/ping/2.0.0')
|
||||
peerInfo.multiaddrs.add('/ip4/127.0.0.1/tcp/0')
|
||||
|
||||
libp2p.peerStore.put(peerInfo)
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
const protocols = ['/ping/1.0.0', 'ping/2.0.0']
|
||||
const multiaddrs = ['/ip4/127.0.0.1/tcp/0']
|
||||
|
||||
libp2p.peerStore.protoBook.add(peerId, protocols)
|
||||
libp2p.peerStore.addressBook.add(peerId, multiaddrs)
|
||||
```
|
||||
|
||||
### Getting a Peer
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerId = ...
|
||||
const peerInfo = libp2p.peerStore.get(peerId)
|
||||
// { id: PeerId, multiaddrs: MultiaddrSet, protocols: Set<string>}
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
const peer = libp2p.peerStore.get(peerId)
|
||||
// { id: PeerId, addresses: Array<{ multiaddr: Multiaddr }>, protocols: Array<string> }
|
||||
```
|
||||
|
||||
### Checking for a Peer
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerId = ...
|
||||
const hasData = libp2p.peerStore.has(peerId)
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
const hasData = Boolean(libp2p.peerStore.get(peerId))
|
||||
```
|
||||
|
||||
### Removing a Peer
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.peerStore.remove(peerId)
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
// Atomic
|
||||
libp2p.peerStore.protoBook.delete(peerId)
|
||||
libp2p.peerStore.addressBook.delete(peerId)
|
||||
// Remove the peer and ALL of its associated data
|
||||
libp2p.peerStore.delete(peerId)
|
||||
```
|
||||
|
||||
### Get all known Peers
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peers = libp2p.peerStore.peers
|
||||
// Map<string, PeerInfo>
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peers = libp2p.peerStore.peers
|
||||
// Similar to libp2p.peerStore.get()
|
||||
// Map<string, { id: PeerId, addresses: Array<{ multiaddr: Multiaddr }>, protocols: Array<string> }
|
||||
```
|
||||
|
||||
## Migrating from Peer Info
|
||||
|
||||
[`PeerInfo`][peer-info] is a libp2p peer abstraction layer that combines a [`PeerId`][peer-id] with known data of the peer, namely its multiaddrs and protocols. It has been used for a long time by `js-libp2p` and its modules to carry this data around the libp2p stack, as well as by the libp2p API, both for providing this data to the users or to receive it from them.
|
||||
|
||||
Since this PeerInfo instances were navigating through the entire codebases, some data inconsistencies could be observed in libp2p. Different libp2p subsystems were running with different visions of the known peers data. For instance, a libp2p subsystem receives a copy of this instance with the peer multiaddrs and protocols, but if new data of the peer is obtained from other subsystem, it would not be updated on the former. Moreover, considering that several subsystems were modifying the peer data, libp2p had no way to determine the accurate data.
|
||||
|
||||
Considering the complete revamp of the libp2p PeerStore towards its second version, the PeerStore now acts as the single source of truth, we do not need to carry [`PeerInfo`][peer-info] instances around. This also solves all the problems stated above, since subsystems will report new observations to the PeerStore.
|
||||
|
||||
### Create
|
||||
|
||||
While it was possible to create a libp2p node without providing a [`PeerInfo`][peer-info], there were 2 use cases where a [`PeerInfo`][peer-info] was provided when creating a libp2p node.
|
||||
|
||||
#### Using an existing PeerId
|
||||
|
||||
`libp2p.create` receives a `peerId` property instead of a `peerInfo` property.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerId = ...
|
||||
const peerInfo = new PeerInfo(peerId)
|
||||
|
||||
const libp2p = await Libp2p.create({
|
||||
peerInfo
|
||||
// ...
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
|
||||
const libp2p = await Libp2p.create({
|
||||
peerId
|
||||
// ...
|
||||
})
|
||||
```
|
||||
|
||||
#### Providing listen addresses
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerId = ...
|
||||
const peerInfo = new PeerInfo(peerId)
|
||||
|
||||
peerInfo.multiaddrs.add('/ip4/127.0.0.1/tcp/0')
|
||||
|
||||
const libp2p = await Libp2p.create({
|
||||
peerInfo
|
||||
// ...
|
||||
})
|
||||
|
||||
await libp2p.start()
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
|
||||
const libp2p = await Libp2p.create({
|
||||
peerId,
|
||||
addresses: {
|
||||
listen: ['/ip4/127.0.0.1/tcp/0']
|
||||
}
|
||||
// ...
|
||||
})
|
||||
await libp2p.start()
|
||||
```
|
||||
|
||||
There is also a bonus regarding the peer addresses. `libp2p@0.28` comes with an AddressManager that also allows the configuration of `announce` and `noAnnounce` addresses.
|
||||
This was possible to achieve before, but in a hacky way by removing or adding addresses to the `peerInfo`, after the node starts.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerId = ...
|
||||
const peerInfo = new PeerInfo(peerId)
|
||||
|
||||
peerInfo.multiaddrs.add('/ip4/127.0.0.1/tcp/8000')
|
||||
|
||||
const libp2p = await Libp2p.create({
|
||||
peerInfo
|
||||
// ...
|
||||
})
|
||||
|
||||
await libp2p.start()
|
||||
peerInfo.multiaddrs.add('/dns4/peer.io') // Announce
|
||||
peerInfo.multiaddrs.delete('/ip4/127.0.0.1/tcp/8000') // Not announce
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
|
||||
const libp2p = await Libp2p.create({
|
||||
peerId,
|
||||
addresses: {
|
||||
listen: ['/ip4/127.0.0.1/tcp/8000'],
|
||||
announce: ['/dns4/peer.io'],
|
||||
noAnnounce: ['/ip4/127.0.0.1/tcp/8000']
|
||||
}
|
||||
// ...
|
||||
})
|
||||
await libp2p.start()
|
||||
```
|
||||
|
||||
### API Implications
|
||||
|
||||
#### Peer Dialing, Hangup and Ping
|
||||
|
||||
`libp2p.dial`, `libp2p.dialProtocol`, `libp2p.hangup` and `libp2p.ping` supported as the target parameter a [`PeerInfo`](peer-info), a [`PeerId`](peer-id), a [`Multiaddr`][multiaddr] and a string representation of the multiaddr. Considering that [`PeerInfo`](peer-info) is being removed from libp2p, all these methods will now support the other 3 possibilities.
|
||||
|
||||
There is one relevant aspect to consider with this change. When using a [`PeerId`](peer-id), the PeerStore **MUST** have known addresses for that peer in its AddressBook, so that it can perform the request. This was also true in the past, but it is important pointing it out because it might not be enough to switch from using [`PeerInfo`](peer-info) to [`PeerId`](peer-id). When using a [`PeerInfo`](peer-info), the PeerStore was not required to have the multiaddrs when they existed on the PeerInfo instance.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerInfo = ... // PeerInfo containing its multiaddrs
|
||||
|
||||
const connection = await libp2p.dial(peerInfo)
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peerId = ...
|
||||
|
||||
// Known multiaddrs should be added to the PeerStore
|
||||
libp2p.peerStore.addressBook.add(peerId, multiaddrs)
|
||||
|
||||
const connection = await libp2p.dial(peerId)
|
||||
```
|
||||
|
||||
#### Content Routing and Peer Routing
|
||||
|
||||
Both [content-routing](https://github.com/libp2p/js-libp2p-interfaces/tree/master/src/content-routing) and [peer-routing](https://github.com/libp2p/js-libp2p-interfaces/tree/master/src/peer-routing) interfaces were modified to not return a ['PeerInfo'][peer-info] instance.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
for await (const peerInfo of libp2p.contentRouting.findProviders(cid)) {
|
||||
// peerInfo is a PeerInfo instance
|
||||
}
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
for await (const peer of libp2p.contentRouting.findProviders(cid)) {
|
||||
// { id: PeerId, multiaddrs: Multiaddr[] }
|
||||
}
|
||||
```
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const peerInfo = await libp2p.peerRouting.findPeer(peerId)
|
||||
// peerInfo is a PeerInfo instance
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const peer = await libp2p.peerRouting.findPeer(peerId)
|
||||
// { id: PeerId, multiaddrs: Multiaddr[] }
|
||||
```
|
||||
|
||||
## Connection Manager and Registrar
|
||||
|
||||
Registrar was introduced in `libp2p@0.27` along with [libp2p topologies](https://github.com/libp2p/js-libp2p-interfaces/tree/master/src/topology). `Registrar` and `ConnectionManager` were both listening on new connections and keeping their record of the open connections with other peers.
|
||||
|
||||
The registrar API was not documented in the [API DOC](../API.md). However, it exposed a useful method for some libp2p users, `libp2p.registrar.getConnection()`. On the other hand, the connection Manager did not provide any methods to access its stored connections. On `libp2p@0.28` we removed this data duplication and the connections are handled solely by the `ConnectionManager`.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
const connection = libp2p.registrar.getConnection(peerId)
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
const connection = libp2p.connectionManager.get(peerId)
|
||||
```
|
||||
|
||||
## Events
|
||||
|
||||
### Connection Events
|
||||
|
||||
Libp2p emits events whenever new connections are established. These emitted events previously providing the [`PeerInfo`](peer-info) of the peer that connected. In `libp2p@0.28` these events are now emitted from the Connection Manager and will now emit the [`connection`](connection) itself.
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.on('peer:connect', (peerInfo) => {
|
||||
// PeerInfo instance
|
||||
})
|
||||
|
||||
libp2p.on('peer:disconnect', (peerInfo) => {
|
||||
// PeerInfo instance
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
libp2p.connectionManager.on('peer:connect', (connection) => {
|
||||
// Connection instance
|
||||
})
|
||||
|
||||
libp2p.connectionManager.on('peer:disconnect', (connection) => {
|
||||
// Connection instance
|
||||
})
|
||||
```
|
||||
|
||||
### Peer Discovery
|
||||
|
||||
**Before**
|
||||
```js
|
||||
libp2p.on('peer:discovery', (peerInfo) => {
|
||||
// PeerInfo instance
|
||||
})
|
||||
```
|
||||
|
||||
**After**
|
||||
```js
|
||||
libp2p.on('peer:discovery', (peerId) => {
|
||||
// peerId instance
|
||||
})
|
||||
```
|
||||
|
||||
## Module Updates

||||
|
||||
With `libp2p@0.28` you should update the following libp2p modules if you are relying on them:
|
||||

There are plenty more Peer Discovery Mechanisms out there, you can:
|
||||
|
||||
- Find one in [libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star). Yes, a transport with discovery capabilities! This happens because WebRTC requires a rendezvous point for peers to exchange [SDP](https://tools.ietf.org/html/rfc4317) offer, which means we have one or more points that can introduce peers to each other. Think of it as MulticastDNS for the Web, as in MulticastDNS only works in LAN.
|
||||
- Any DHT will offer you a discovery capability. You can simple _random-walk_ the routing tables to find other peers to connect to. For example [libp2p-kad-dht](https://github.com/libp2p/js-libp2p-kad-dht) can be used for peer discovery. An example how to configure it to enable random walks can be found [here](https://github.com/libp2p/js-libp2p/blob/v0.28.4/doc/CONFIGURATION.md#customizing-dht).

A byproduct of having these encrypted communications modules is that we can authenticate the peers we are dialing to. You might have noticed that every time we dial to a peer in libp2p space, we always use its PeerId at the end (e.g /ip4/127.0.0.1/tcp/89765/p2p/QmWCbVw1XZ8hiYBwwshPce2yaTDYTqTaP7GCHGpry3ykWb), this PeerId is generated by hashing the Public Key of the peer. With this, we can create a crypto challenge when dialing to another peer and prove that peer is the owner of a PrivateKey that matches the Public Key we know.

If you want to want to learn more about how SECIO works, you can read the [great write up done by Dominic Tarr](https://github.com/auditdrivencrypto/secure-channel/blob/master/prior-art.md#ipfss-secure-channel).
|
||||
|
||||
Important note: SECIO hasn't been audited and so, we do not recommend to trust its security. We intent to move to TLS 1.3 once the specification is finalized and an implementation exists that we can use.

## Signaling Server
|
||||
|
||||
This example uses the `libp2p-webrtc-star` module, which enables libp2p browser nodes to establish direct connections to one another via a central signaling server. For this example, we are using the signaling server that ships with `libp2p-webrtc-star`.
|
||||
|
||||
You can start the server by running `npm run server`. This will start a signaling server locally on port `9090`. If you'd like to run a signaling server outside of this example, you can see instructions on how to do so in the [`libp2p-webrtc-star` README](https://github.com/libp2p/js-libp2p-webrtc-star).
|
||||
|
||||
When you run the server, you should see output that looks something like this:
|
||||
|
||||
```log
|
||||
$ npm run server
|
||||
|
||||
> libp2p-in-browser@1.0.0 server
|
||||
> star-signal
|
||||
|
||||
Listening on: http://0.0.0.0:9090
|
||||
```
|
||||
|
||||
## Running the examples
|
||||
|
||||
Start by running the Parcel server:
|
||||
Once you have started the signaling server, you can run the Parcel server.
|
||||
|
||||
```
|
||||
npm start
|
||||
@ -36,11 +53,3 @@ This will compile the code and start a server listening on port [http://localhos
|
||||
Now, if you open a second browser tab to `http://localhost:1234`, you should discover your node from the previous tab. This is due to the fact that the `libp2p-webrtc-star` transport also acts as a Peer Discovery interface. Your node will be notified of any peer that connects to the same signaling server you are connected to. Once libp2p discovers this new peer, it will attempt to establish a direct WebRTC connection.
|
||||
|
||||
**Note**: In the example we assign libp2p to `window.libp2p`, in case you would like to play around with the API directly in the browser. You can of course make changes to `index.js` and Parcel will automatically rebuild and reload the browser tabs.
|
||||
|
||||
## Going to production?
|
||||
|
||||
This example uses public `libp2p-webrtc-star` servers. These servers should be used for experimenting and demos, they **MUST** not be used in production as there is no guarantee on availability.
|
||||
|
||||
You can see how to deploy your own signaling server in [libp2p/js-libp2p-webrtc-star/DEPLOYMENT.md](https://github.com/libp2p/js-libp2p-webrtc-star/blob/master/DEPLOYMENT.md).
|
||||
|
||||
Once you have your own server running, you should add its listen address in your libp2p node configuration.

`libp2p-circuit` implements the circuit-relay mechanism that allows nodes that don't speak the same protocol to communicate using a third _relay_ node. You can read more about this in its [spec](https://github.com/libp2p/specs/tree/master/relay).

### libp2p-circuit and IPFS
|
||||
|
||||
Prior to `libp2p-circuit` there was a rift in the IPFS network, were IPFS nodes could only access content from nodes that speak the same protocol, for example TCP only nodes could only dial to other TCP only nodes, same for any other protocol combination. In practice, this limitation was most visible in JS-IPFS browser nodes, since they can only dial out but not be dialed in over WebRTC or WebSockets, hence any content that the browser node held was not reachable by the rest of the network even through it was announced on the DHT. Non browser IPFS nodes would usually speak more than one protocol such as TCP, WebSockets and/or WebRTC, this made the problem less severe outside of the browser. `libp2p-circuit` solves this problem completely, as long as there are `relay nodes` capable of routing traffic between those nodes their content should be available to the rest of the IPFS network.

## Usage
|
||||
|
||||
Libp2p circuit configuration can be seen at [Setup with Relay](../../doc/CONFIGURATION.md#setup-with-relay).
|
||||
### Example
|
||||
|
||||
Once you have a circuit relay node running, you can configure other nodes to use it as a relay as follows:
|
||||
#### Create dialer/listener
|
||||
|
||||
```js
|
||||
const Circuit = require('libp2p-circuit')
|
||||
const multiaddr = require('multiaddr')
|
||||
const Libp2p = require('libp2p')
|
||||
const TCP = require('libp2p-tcp')
|
||||
const MPLEX = require('libp2p-mplex')
|
||||
const SECIO = require('libp2p-secio')
|
||||
const pull = require('pull-stream')
|
||||
|
||||
const relayAddr = ...
|
||||
const mh1 = multiaddr('/p2p-circuit/p2p/QmHash') // dial /p2p/QmHash over any circuit
|
||||
|
||||
const node = await Libp2p.create({
|
||||
addresses: {
|
||||
listen: [multiaddr(`${relayAddr}/p2p-circuit`)]
|
||||
},
|
||||
modules: {
|
||||
transport: [TCP],
|
||||
streamMuxer: [MPLEX],
|
||||
connEncryption: [SECIO]
|
||||
},
|
||||
config: {
|
||||
relay: { // Circuit Relay options (this config is part of libp2p core configurations)
|
||||
enabled: true // Allows you to dial and accept relayed connections. Does not make you a relay.
|
||||
}
|
||||
}
|
||||
const circuit = new Circuit(swarmInstance, options) // pass swarm instance and options
|
||||
|
||||
const listener = circuit.createListener(mh1, (connection) => {
|
||||
console.log('new connection opened')
|
||||
pull(
|
||||
pull.values(['hello']),
|
||||
socket
|
||||
)
|
||||
})
|
||||
|
||||
listener.listen(() => {
|
||||
console.log('listening')
|
||||
|
||||
pull(
|
||||
circuit.dial(mh1),
|
||||
pull.log,
|
||||
pull.onEnd(() => {
|
||||
circuit.close()
|
||||
})
|
||||
)
|
||||
})
|
||||
```
|
||||
|
||||
Outputs:
|
||||
|
||||
```sh
|
||||
listening
|
||||
new connection opened
|
||||
hello
|
||||
```
|
||||
|
||||
#### Create `relay`
|
||||
|
||||
```js
|
||||
const Relay = require('libp2p-circuit').Relay
|
||||
|
||||
const relay = new Relay(options)
|
||||
|
||||
relay.mount(swarmInstance) // start relaying traffic
|
||||
```

### Implementation rational
|
||||
|
||||
This module is not a transport, however it implements `interface-transport` interface in order to allow circuit to be plugged with `libp2p`. The rational behind it is that, `libp2p-circuit` has a dial and listen flow, which fits nicely with other transports, moreover, it requires the _raw_ connection to be encrypted and muxed just as a regular transport's connection does. All in all, `interface-transport` ended up being the correct level of abstraction for circuit, as well as allowed us to reuse existing integration points in `libp2p` and `libp2p` without adding any ad-hoc logic. All parts of `interface-transport` are used, including `.getAddr` which returns a list of `/p2p-circuit` addresses that circuit is currently listening.

# js-libp2p-keychain
|
||||
|
||||
> A secure key chain for libp2p in JavaScript
|
||||
|
||||
## Features
|
||||
|
||||
- Manages the lifecycle of a key
|
||||
- Keys are encrypted at rest
|
||||
- Enforces the use of safe key names
|
||||
- Uses encrypted PKCS 8 for key storage
|
||||
- Uses PBKDF2 for a "stetched" key encryption key
|
||||
- Enforces NIST SP 800-131A and NIST SP 800-132
|
||||
- Uses PKCS 7: CMS (aka RFC 5652) to provide cryptographically protected messages
|
||||
- Delays reporting errors to slow down brute force attacks
|
||||
|
||||
### KeyInfo
|
||||
|
||||
The key management and naming service API all return a `KeyInfo` object. The `id` is a universally unique identifier for the key. The `name` is local to the key chain.
|
||||
|
||||
```js
|
||||
{
|
||||
name: 'rsa-key',
|
||||
id: 'QmYWYSUZ4PV6MRFYpdtEDJBiGs4UrmE6g8wmAWSePekXVW'
|
||||
}
|
||||
```
|
||||
|
||||
The **key id** is the SHA-256 [multihash](https://github.com/multiformats/multihash) of its public key. The *public key* is a [protobuf encoding](https://github.com/libp2p/js-libp2p-crypto/blob/master/src/keys/keys.proto.js) containing a type and the [DER encoding](https://en.wikipedia.org/wiki/X.690) of the PKCS [SubjectPublicKeyInfo](https://www.ietf.org/rfc/rfc3279.txt).
|
||||
|
||||
### Private key storage
|
||||
|
||||
A private key is stored as an encrypted PKCS 8 structure in the PEM format. It is protected by a key generated from the key chain's *passPhrase* using **PBKDF2**.
|
||||
|
||||
The default options for generating the derived encryption key are in the `dek` object. This, along with the passPhrase, is the input to a `PBKDF2` function.
|
||||
|
||||
```js
|
||||
const defaultOptions = {
|
||||
//See https://cryptosense.com/parameter-choice-for-pbkdf2/
|
||||
dek: {
|
||||
keyLength: 512 / 8,
|
||||
iterationCount: 1000,
|
||||
salt: 'at least 16 characters long',
|
||||
hash: 'sha2-512'
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
### Physical storage
|
||||
|
||||
The actual physical storage of an encrypted key is left to implementations of [interface-datastore](https://github.com/ipfs/interface-datastore/). A key benifit is that now the key chain can be used in browser with the [js-datastore-level](https://github.com/ipfs/js-datastore-level) implementation.
|
||||
|
||||
### Cryptographic Message Syntax (CMS)
|
||||
|
||||
CMS, aka [PKCS #7](https://en.wikipedia.org/wiki/PKCS) and [RFC 5652](https://tools.ietf.org/html/rfc5652), describes an encapsulation syntax for data protection. It is used to digitally sign, digest, authenticate, or encrypt arbitrary message content. Basically, `cms.encrypt` creates a DER message that can be only be read by someone holding the private key.

|
||||
|

The PeerStore manages the high level operations on its inner books. Moreover, the PeerStore should be responsible for notifying interested parties of relevant events, through its Event Emitter.
|
||||
|
||||
## Submitting records to the PeerStore
|
||||
## Data gathering
|
||||
|
||||
Several libp2p subsystems will perform operations that might gather relevant information about peers.
|
||||
Several libp2p subsystems will perform operations, which will gather relevant information about peers. Some operations might not have this as an end goal, but can also gather important data.
|
||||
|
||||
### Identify
|
||||
- The Identify protocol automatically runs on every connection when multiplexing is enabled. The protocol will put the multiaddrs and protocols provided by the peer to the PeerStore.
|
||||
- In the background, the Identify Service is also waiting for protocol change notifications of peers via the IdentifyPush protocol. Peers may leverage the `identify-push` message to communicate protocol changes to all connected peers, so that their PeerStore can be updated with the updated protocols.
|
||||
- While it is currently not supported in js-libp2p, future iterations may also support the [IdentifyDelta protocol](https://github.com/libp2p/specs/pull/176).
|
||||
- Taking into account that the Identify protocol records are directly from the peer, they should be considered the source of truth and weighted accordingly.
|
||||
In a libp2p node's life, it will discover peers through its discovery protocols. In a typical discovery protocol, addresses of the peer are discovered along with its peer id. Once this happens, the PeerStore should collect this information for future (or immediate) usage by other subsystems. When the information is stored, the PeerStore should inform interested parties of the peer discovered (`peer` event).
|
||||
|
||||
### Peer Discovery
|
||||
- Libp2p discovery protocols aim to discover new peers in the network. In a typical discovery protocol, addresses of the peer are discovered along with its peer id. Once this happens, a libp2p discovery protocol should emit a `peer` event with the information of the discovered peer and this information will be added to the PeerStore by libp2p.
|
||||
Taking into account a different scenario, a peer might perform/receive a dial request to/from a unkwown peer. In such a scenario, the PeerStore must store the peer's multiaddr once a connection is established.
|
||||
|
||||
### Dialer
|
||||
- Libp2p API supports dialing a peer given a `multiaddr`, and no prior knowledge of the peer. If the node is able to establish a connection with the peer, it and its multiaddr is added to the PeerStore.
|
||||
- When a connection is being upgraded, more precisely after its encryption, or even in a discovery protocol, a libp2p node can get to know other parties public keys. In this scenario, libp2p will add the peer's public key to its `KeyBook`.
|
||||
After a connection is established with a peer, the Identify protocol will run automatically. A stream is created and peers exchange their information (Multiaddrs, running protocols and their public key). Once this information is obtained, it should be added to the PeerStore. In this specific case, as we are speaking to the source of truth, we should ensure the PeerStore is prioritizing these records. If the recorded `multiaddrs` or `protocols` have changed, interested parties must be informed via the `change:multiaddrs` or `change:protocols` events respectively.
|
||||
|
||||
### DHT
|
||||
- On some DHT operations, such as finding providers for a given CID, nodes may exchange peer data as part of the query. This passive peer discovery should result in the DHT emitting the `peer` event in the same way [Peer Discovery](#peerdiscovery) does.
|
||||
In the background, the Identify Service is also waiting for protocol change notifications of peers via the IdentifyPush protocol. Peers may leverage the `identify-push` message to communicate protocol changes to all connected peers, so that their PeerStore can be updated with the updated protocols. As the `identify-push` also sends complete and updated information, the data in the PeerStore can be replaced.
|
||||
|
||||
## Retrieving records from the PeerStore
|
||||
(To consider: Should we not replace until we get to multiaddr confidence? we might loose true information as we will talk with older nodes on the network.)
|
||||
|
||||
When data in the PeerStore is updated the PeerStore will emit events based on the changes, to allow applications and other subsystems to take action on those changes. Any subsystem interested in these notifications should subscribe the [`PeerStore events`][peer-store-events].
|
||||
While it is currently not supported in js-libp2p, future iterations may also support the [IdentifyDelta protocol](https://github.com/libp2p/specs/pull/176).
|
||||
|
||||
### Peer
|
||||
- Each time a new peer is discovered, the PeerStore should emit a [`peer` event][peer-store-events], so that interested parties can leverage this peer and establish a connection with it.
|
||||
It is also possible to gather relevant information for peers from other protocols / subsystems. For instance, in `DHT` operations, nodes can exchange peer data as part of the `DHT` operation. In this case, we can learn additional information about a peer we already know. In this scenario the PeerStore should not replace the existing data it has, just add it.
|
||||
|
||||
### Protocols
|
||||
- When the known protocols of a peer change, the PeerStore emits a [`change:protocols` event][peer-store-events].
|
||||
## Data Consumption
|
||||
|
||||
### Multiaddrs
|
||||
- When the known listening `multiaddrs` of a peer change, the PeerStore emits a [`change:multiaddrs` event][peer-store-events].
|
||||
When the PeerStore data is updated, this information might be important for different parties.
|
||||
|
||||
Every time a peer needs to dial another peer, it is essential that it knows the multiaddrs used by the peer, in order to perform a successful dial to it. The same is true for pinging a peer. While the `AddressBook` is going to keep its data updated, it will also emit `change:multiaddrs` events so that subsystems/users interested in knowing these changes can be notified instead of polling the `AddressBook`.
|
||||
|
||||
Everytime a peer starts/stops supporting a protocol, libp2p subsystems or users might need to act accordingly. `js-libp2p` registrar orchestrates known peers, established connections and protocol topologies. This way, once a protocol is supported for a peer, the topology of that protocol should be informed that a new peer may be used and the subsystem can decide if it should open a new stream with that peer or not. For these situations, the `ProtoBook` will emit `change:protocols` events whenever supported protocols of a peer change.

- `change:multiaadrs` - emitted when a known peer has a different set of multiaddrs.
|
||||
- `change:protocols` - emitted when a known peer supports a different set of protocols.
|
||||
- `change:pubkey` - emitted when a peer's public key is known.
|
||||
- `change:metadata` - emitted when known metadata of a peer changes.
|
||||
|
||||
## Data Persistence
|
||||
|
||||
The data stored in the PeerStore can be persisted if configured appropriately. Keeping a record of the peers already discovered by the peer, as well as their known data aims to improve the efficiency of peers joining the network after being offline.
|
||||
|
||||
The libp2p node will need to receive a [datastore](https://github.com/ipfs/interface-datastore), in order to persist this data across restarts. A [datastore](https://github.com/ipfs/interface-datastore) stores its data in a key-value fashion. As a result, we need coherent keys so that we do not overwrite data.
|
||||
|
||||
The PeerStore should not continuously update the datastore whenever data is changed. Instead, it should only store new data after reaching a certain threshold of "dirty" peers, as well as when the node is stopped, in order to batch writes to the datastore.
|
||||
|
||||
The peer id will be appended to the datastore key for each data namespace. The namespaces were defined as follows:
|
||||
|
||||
**AddressBook**
|
||||
|
||||
All the known peer addresses are stored with a key pattern as follows:
|
||||
|
||||
`/peers/addrs/<b32 peer id no padding>`
|
||||
|
||||
**ProtoBook**
|
||||
|
||||
All the known peer protocols are stored with a key pattern as follows:
|
||||
|
||||
`/peers/protos/<b32 peer id no padding>`
|
||||
|
||||
**KeyBook**
|
||||
|
||||
All public keys are stored under the following pattern:
|
||||
|
||||
` /peers/keys/<b32 peer id no padding>`
|
||||
|
||||
**MetadataBook**
|
||||
|
||||
Metadata is stored under the following key pattern:
|
||||
|
||||
`/peers/metadata/<b32 peer id no padding>/<key>`
|
||||
|
||||
## Future Considerations
|
||||
|
||||
- If multiaddr TTLs are added, the PeerStore may schedule jobs to delete all addresses that exceed the TTL to prevent AddressBook bloating
|
||||
- Further API methods will probably need to be added in the context of multiaddr validity and confidence.
|
||||
- When improving libp2p configuration for specific runtimes, we should take into account the PeerStore recommended datastore.
|
||||
- When improving libp2p configuration, we should think about a possible way of allowing the configuration of Bootstrap to be influenced by the persisted peers, as a way to decrease the load on Bootstrap nodes.
