🛡️ TLSBridge – Secure Minecraft Connections Over TLS

TLSBridge is a lightweight Paper plugin designed for Minecraft servers hosted behind CGNAT or without public IP access. It enables encrypted TLS connections to your server, allowing players to connect seamlessly using secure tunneling (via Tailscale Funnel or similar) on port 443.

🔧 Features

✅ TLS Support for Minecraft: Accepts inbound connections over TLS (HTTPS-style), translating them into standard Minecraft connections.

🌐 Use with Tailscale Funnel: Perfectly integrates with Tailscale's funnel to expose your server on 443, even behind CGNAT.

🛠️ No Port Forwarding Needed: Avoid router configuration and host your server securely using a domain like your-server.tailnet.ts.net.

🔒 Built-in Certificate Generation: Automatically generates a self-signed TLS certificate for secure tunneling.

⚙️ Plug and Play: Just drop the plugin in and run your Paper server. Simple config, no bloat.

🧠 How It Works

When the plugin is enabled:

It launches a TLS listener on port 10000

Decrypts incoming TLS connections (from a service like Tailscale Funnel)

Forwards them into the Minecraft server on port 25565

With Tailscale set to forward external :443 traffic to localhost:10000, TLSBridge acts as a secure gateway into your Minecraft world.
