iotpatch 0.2.0

IoT Security Hardening Toolkit for Edge Devices

🧩 IoTPatch — Secure, Auto-Patching Framework for IoT Devices

---

🔒 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.
