### Features

Core

- 🔐 End‑to‑end RSA encryption — automatic keypair generation and real‑time public key sync

- 🔑 Public Key Monitor — live view of all known keys, drives encryption state

- 📦 Length‑prefixed packet framing — no desync, no corrupted packets

- 🌐 Async TCP networking — clean connect/disconnect cycle.

Client

- 👥 Real‑time user list — updates automatically on login/logout

- 😀 UTF‑8 messaging — emoji‑compatible

- 🔌 Configurable TCP port — choose the port before connecting

- 🏠 Local mode — runs locally if no IP address is provided

- 🪟 System tray integration — minimize/close to tray

- 🎨 Theme toggle — light/dark themes switchable at any time

- 🌐 Instant language switching — localized in French, Spanish and English

- ✏️ Adjustable input field — resize or shift it horizontally to match your layout preferences

- 🎞️ Subtle WPF animations using xaml storyboards and UI polish

Server

- ⚡ Async TCP engine — handles multiple clients concurrently with non‑blocking I/O

- 📡 Broadcast & routing logic — distributes messages to all connected clients

Architecture

- 🧱 Three‑module structure — Client, Server, Protocol

- 🧩 MVVM‑light — clean separation of UI and logic

- 🔧 Custom packet reader/writer — opcode‑based routing
