ap-client 0.3.0

Noise Protocol Clients for access-protocol

This crate provides both remote and user client implementations for connecting through a proxy using the Noise Protocol.

Features

• PSK-based authentication using pairing codes
• Noise Protocol NNpsk2 pattern for secure 2-message handshake
• Session caching for reconnection without re-pairing
• Supports both classical (Curve25519) and post-quantum (Kyber768) cryptography

Remote Client Usage (untrusted device)

use ap_client::{RemoteClient, DefaultProxyClient, IdentityProvider, SessionStore};
use ap_proxy_client::ProxyClientConfig;
use tokio::sync::mpsc;

// Create proxy client
let proxy_client = Box::new(DefaultProxyClient::new(ProxyClientConfig {
    proxy_url: "ws://localhost:8080".to_string(),
    identity_keypair: Some(identity_provider.identity().to_owned()),
}));

let (event_tx, mut event_rx) = mpsc::channel(32);
let (response_tx, response_rx) = mpsc::channel(32);

let mut client = RemoteClient::new(
    identity_provider,
    session_store,
    event_tx,
    response_rx,
    proxy_client,
).await?;

// Pair with rendezvous code
client.pair_with_handshake("ABCDEF123").await?;

let query = ap_client::CredentialQuery::Domain("example.com".to_string());
let credential = client.request_credential(&query).await?;

User Client Usage (trusted device)

use ap_client::{
    DefaultProxyClient, IdentityProvider, UserClient, UserClientEvent, UserClientResponse,
};
use ap_proxy_client::ProxyClientConfig;
use tokio::sync::mpsc;

// Create proxy client
let proxy_client = Box::new(DefaultProxyClient::new(ProxyClientConfig {
    proxy_url: "ws://localhost:8080".to_string(),
    identity_keypair: Some(identity_provider.identity().to_owned()),
}));

let (event_tx, event_rx) = mpsc::channel(32);
let (response_tx, response_rx) = mpsc::channel(32);

let mut client = UserClient::listen(
    identity_provider,
    session_store,
    proxy_client,
).await?;

// Enable PSK mode or rendezvous mode
client.enable_psk(event_tx, response_rx).await?;
