Noise protocol framework support for libp2p.

This crate provides libp2p_core::InboundUpgrade and libp2p_core::OutboundUpgrade implementations for various noise handshake patterns (currently IK, IX, and XX) over a particular choice of DH key agreement (currently only X25519).

All upgrades produce as output a pair, consisting of the remote's static public key and a NoiseOutput which represents the established cryptographic session with the remote, implementing tokio_io::AsyncRead and tokio_io::AsyncWrite.

Usage

Example:

use libp2p_core::Transport;
use libp2p_tcp::TcpConfig;
use libp2p_noise::{Keypair, X25519, NoiseConfig};

# fn main() {
let keys = Keypair::<X25519>::new();
let transport = TcpConfig::new().with_upgrade(NoiseConfig::xx(keys));
// ...
# }
