> Noise libp2p handshake for js-libp2p

This repository contains TypeScript implementation of noise protocol, an encryption protocol used in libp2p.

##### Warning: Even though this package works in browser, it will bundle around 600Kb (200Kb gzipped) of code

https://bundlephobia.com/result?p=@chainsafe/libp2p-noise@latest

## Usage

Install with `yarn add @chainsafe/libp2p-noise` or `npm i @chainsafe/libp2p-noise`.

Example of using default noise configuration and passing it to the libp2p config:

```js

import {createLibp2p} from "libp2p"

import {noise} from "@chainsafe/libp2p-noise"

//custom noise configuration, pass it instead of `noise()`

//x25519 private key

const n = noise({ staticNoiseKey });

const libp2p = await createLibp2p({

  connectionEncryption: [noise()],

  //... other options

})

```

See the [NoiseInit](https://github.com/ChainSafe/js-libp2p-noise/blob/master/src/noise.ts#L29-L38) interface for noise configuration options.

## API

This module exposes an implementation of the [ConnectionEncrypter](https://libp2p.github.io/js-libp2p/interfaces/_libp2p_interface.connection_encrypter.ConnectionEncrypter.html) interface.

## Bring your own crypto

You can provide a custom crypto implementation (instead of the default, based on [@noble](https://paulmillr.com/noble/)) by adding a `crypto` field to the init argument passed to the `Noise` factory.

The implementation must conform to the `ICryptoInterface`, defined in https://github.com/ChainSafe/js-libp2p-noise/blob/master/src/crypto.ts
