### 🔒 Overview

**IoTPatch** is a Python-based **secure IoT firmware patching framework** designed to demonstrate **encrypted update delivery** and **authenticated device connectivity** over **MQTT with TLS**.

It provides a modular interface to:
- ✅ Establish **secure MQTT communication** between IoT nodes and servers.  
- 🔐 Manage **firmware updates and patches** safely using certificate-based authentication.  
- ⚙️ Integrate lightweight security layers for **IoT edge devices** with minimal dependencies.

Ideal for **IoT security researchers, embedded developers, and students** exploring **secure OTA (Over-The-Air)** update mechanisms.
