Module server 

Proxy server implementation.

This module provides the server-side implementation of the ap-proxy server. The server can be run standalone using the binary, or embedded in custom applications.

Running as a Binary

The simplest way to run the proxy server:

cargo run --bin ap-proxy

Embedding in Your Application

You can embed the proxy server in your own application:

use ap_proxy::server::ProxyServer;
use std::net::SocketAddr;

let addr: SocketAddr = "127.0.0.1:8080".parse()?;
let server = ProxyServer::new(addr);

// Run the server (blocks until shutdown)
server.run().await?;

Server Responsibilities

The proxy server:

• Accepts WebSocket connections from clients
• Authenticates clients using MlDsa65 challenge-response
• Manages rendezvous codes for peer discovery
• Routes messages between authenticated clients
• Cleans up expired rendezvous codes automatically

Security Considerations

The server operates as a zero-knowledge proxy:

• Verifies client identities via cryptographic signatures
• Routes messages based on fingerprints
• Does not decrypt or inspect message payloads
• Sees metadata: source, destination, timing, message size

Structs
