# tokio-noise

An authenticated encryption layer on top of [tokio](https://tokio.rs) streams, driven by the [Noise Protocol Framework](https://noiseprotocol.org/).

This library is [sponsored by dlcBTC](https://www.dlcbtc.com).

## Usage

```rust

use tokio::net::{TcpListener, TcpStream};

use tokio_noise::{NoiseError, NoiseTcpStream};

const PSK: [u8; 32] = [0xFF; 32];

async fn run_noise_server(tcp_stream: TcpStream) -> Result<(), NoiseError> {

    let mut noise_stream = NoiseTcpStream::handshake_responder_psk0(tcp_stream, &PSK).await?;

    let mut buf = [0u8; 1024];

    let n = noise_stream.recv(&mut buf).await?;

    assert_eq!(&buf[..n], b"hello world");

    Ok(())

}

#[tokio::main]

async fn main() -> Result<(), NoiseError> {

    let listener = TcpListener::bind("127.0.0.1:0").await?;

    let addr = listener.local_addr()?;

    let srv = tokio::task::spawn(async move {

        let (tcp_stream, _) = listener.accept().await?;

        run_noise_server(tcp_stream).await

    });

    // Client

    let tcp_stream = TcpStream::connect(&addr).await?;

    let mut noise_stream = NoiseTcpStream::handshake_initiator_psk0(tcp_stream, &PSK).await?;

    noise_stream.send(b"hello world").await?;

    // Wait for server to finish

    srv.await.unwrap()?;

    Ok(())

}

```
