> Noise libp2p handshake for js-libp2p

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

## Usage

When published, package should be imported as: `import { Noise } from 'libp2p-noise'`.

Example of instantiating noise and passing it to the libp2p config:
```
const NOISE = new Noise(privateKey);

const libp2p = new Libp2p({
   modules: {
     connEncryption: [NOISE],
   },
});
```

Where parameters for Noise constructor are:
 - *private key* - required parameter (32 bytes libp2p peer private key)
 - *static Noise key* - (optional) existing private Noise static key
 - *early data* - (optional) an early data payload to be sent in handshake messages
 


## API

This module exposes a crypto interface, as defined in the repository [js-interfaces](https://github.com/libp2p/js-interfaces).
