Secio 协议是一个中间件，它将加密和解密通过套接字（或任何实现 AsyncRead + AsyncWrite）进行的通信。

使用方法

SecioConfig 实现 InboundUpgrade 和 OutboundUpgrade，因此充当传输认证的连接升级。请参阅 authenticate。

use futures::prelude::*;
use secio::{SecioConfig, SecioOutput};
use tet_libp2p_core::{PeerId, Multiaddr, identity, upgrade};
use tet_libp2p_core::transport::Transport;
use tet_libp2p_mplex::MplexConfig;
use tet_libp2p_tcp::TcpConfig;

// Create a local peer identity.
let local_keys = identity::Keypair::generate_ed25519();

// Create a `Transport`.
let transport = TcpConfig::new()
    .upgrade(upgrade::Version::V1)
    .authenticate(SecioConfig::new(local_keys.clone()))
    .multiplex(MplexConfig::default());

// The transport can be used with a `Network` from `tet-libp2p-core`, or a
// `Swarm` from from `tet-libp2p-swarm`. See the documentation of these
// crates for mode details.

// let network = Network::new(transport, local_keys.public().into_peer_id());
// let swarm = Swarm::new(transport, behaviour, local_keys.public().into_peer_id());
