libp2p-noise 0.12.0-alpha.1

Cryptographic handshake protocol using the noise framework.

Noise protocol framework support for libp2p.

Note: This crate is still experimental and subject to major breaking changes both on the API and the wire protocol.

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 Diffie–Hellman 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 futures::io::AsyncRead and futures::io::AsyncWrite.

Usage

Example:

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

# fn main() {
let id_keys = identity::Keypair::generate_ed25519();
let dh_keys = Keypair::<X25519>::new().into_authentic(&id_keys).unwrap();
let noise = NoiseConfig::xx(dh_keys).into_authenticated();
let builder = TcpConfig::new().upgrade(upgrade::Version::V1).authenticate(noise);
// let transport = builder.multiplex(...);
# }
