## Features
- [x] Encrypted configuration files
- [x] Encrypted communication (SSL for all traffic)
- [x] Hole-punching support: TCP (including IPv6) and UDP
- [x] Hole-punching library: Use `linker.tunnel` in your projects
- [x] Relay connections with seamless switch to direct P2P once a hole is punched
- [x] Cross-LAN networking: Virtual NIC for building LANs between clients (P2P, point-to-network, network-to-network)
- [x] Virtual NIC library: Use `linker.tun` in your projects
- [x] Port forwarding: Forward local ports to remote client ports
- [x] Server penetration: Register ports/domains on a server to access internal services
- [x] Permission management: Master client controls permissions, exports/configures sub-client settings
- [x] Custom authentication: Validate connections via `HTTP POST` for beacon, relay, and penetration
- [x] Traffic statistics: Track beacon, relay, and penetration traffic on servers
- [x] Network configuration: Master client sets up networks, auto-assigns IPs to all clients
- [x] Distributed architecture: Multiple relay nodes for massive scalability
- [x] SOCKS5 proxy: Dynamic port forwarding without specifying ports
- [x] Easy integration: Use `linker.messenger.entry` to embed into your projects
- [x] CDKEY，It can temporarily lift certain restrictions

## Quick Integration
In a .NET 8+ project, install the NuGet package `linker.messenger.entry`
```
LinkerMessengerEntry.Initialize();
LinkerMessengerEntry.Build();
LinkerMessengerEntry.Setup(ExcludeModule.None);
```
