TLS Server Example

Demonstrates the custom TLS server implementation built from scratch. Shows TLS configuration with certificate/key PEM files, ALPN negotiation, HTTP/1.1 and HTTP/2 over TLS, and TLS client handshake.

Demo Program

// Create a server with TLS enabled
var server = httpx.Server.initWithConfig(allocator, .{
    .host = "127.0.0.1",
    .port = port,
    .tls_enabled = true,
    .tls_cert_path = "examples/certs/server.crt",
    .tls_key_path = "examples/certs/server.key",
    .tls_alpn_protocols = &.{ "h2", "http/1.1" },
    .http2_enabled = true,
});

// TLS client handshake
var session = tls.TlsSession.init(tls_config);
session.socket = &sock;
session.handshake("127.0.0.1");
const protocol = session.negotiatedProtocol();

Run

zig build run-tls_server

Checklist

• [x] Server starts with TLS enabled
• [x] Certificate and key PEM files are loaded
• [x] TLS handshake completes successfully
• [x] ALPN negotiates h2 or http/1.1
• [x] HTTP/2 is detected via ALPN
• [x] HTTP request over TLS returns 200 OK
• [x] Supports TLS 1.2 and 1.3 cipher suites
• [x] Record-level fragmentation works correctly
