Wiznet makers

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.
