# Enhanced ESP32 W5500 Ethernet Module with SSL Support

## Article

We came across an open-source project on GitHub called **ESP32-Wiznet-W5500-SSL-MicroPython**, which brings SSL/TLS capabilities to an ESP32 + W5500 Ethernet setup under MicroPython.

### What this project does

- It connects an ESP32 board to a **WIZnet W5500** Ethernet module and enables HTTP and HTTPS communication with SSL/TLS support.

- The implementation includes modules like `ssl_wrapper`, `enhanced_requests`, and extended error handling to support secure communication.

- You’ll find example scripts, compiled `.mpy` versions, and a test suite to validate HTTP/HTTPS operations.

### Why this matters

Adding SSL/TLS support to embedded devices using Ethernet is valuable, especially for IoT systems handling sensitive data. This project offers a bridge between hardware (ESP32 + W5500) and secure internet protocols, making it possible to build more robust and secure systems without relying solely on Wi-Fi.

### Limitations & things to watch

The original version of the project (non-SSL) supported only HTTP, not HTTPS.

Integration of SSL adds complexity (certificate validation, library dependencies, etc.).

Real-world deployment may require tuning timeouts, verifying cipher suites, and handling connectivity robustness.
