ESP32 JWT Authentication with ESP-IDF 🚀

Overview 🌐

Welcome to the ESP32 JWT Authentication repository! This project demonstrates how to implement JSON Web Token (JWT) authentication on an ESP32 microcontroller using the ESP-IDF framework in Visual Studio Code. Ideal for secure communication in IoT applications! 🔒

Features ✨

• Secure Authentication: Utilizes JWT for stateless authentication. 🛡️
• ESP-IDF Compatibility: Built with the ESP-IDF framework for advanced ESP32 projects. ⚙️
• Modular Design: Easy to integrate with existing applications. 🔄
• Robust Handling: Efficient JWT management for secure API communication. 📡

Getting Started 🚀

Prerequisites 📋

Before you begin, ensure you have the following:

• ESP32 Board: Any compatible ESP32 development board. 🖥️
• ESP-IDF: Install the latest version from the ESP-IDF official website. 📚
• Visual Studio Code: Install VS Code along with the ESP-IDF extension. 💻

Installation 🛠️

1. Clone the Repository 📥

   git clone https://github.com/euginfrancis/ESP32_JWT_Auth.git
   cd ESP32_JWT_Auth

2. Set Up ESP-IDF Environment 🌟

   Follow the instructions in the ESP-IDF documentation to set up your development environment.

3. Configure Wi-Fi Credentials 📶

   Edit the sdkconfig or the respective configuration file to set your Wi-Fi SSID and password.

4. Build and Flash the Project 🔄

   Use the following commands in the terminal:

   idf.py menuconfig    # Configure project settings
   idf.py build          # Build the project
   idf.py flash          # Flash the project to your ESP32

5. Example Usage 📖 This project includes an example to demonstrate JWT authentication. Follow the instructions in the code comments to test the functionality.

How It Works 🔍

• Authentication Flow: The ESP32 sends a request to an authentication server to obtain a JWT. 📨
• Token Storage: The JWT is securely stored in memory for subsequent use. 💾
• API Calls: The ESP32 includes the JWT in the HTTP headers for authenticating further requests. 📢
