UnlockECU

All security algorithms are reverse-engineered and reimplemented in C#, eliminating reliance on proprietary DLLs and allowing free distribution without legal concerns, as stated in the README.

The core is a portable .NET 5 class library, making it easy to integrate into custom automotive diagnostic tools or other platforms, per the project's design philosophy.

Supports adding custom ECU definitions via JSON files, enabling users to extend support for new targets without modifying the core code, as detailed in the 'Adding definitions' section.

Includes over 25 pre-implemented security providers for major brands like Bosch and Volkswagen, covering many common ECU models, based on the listed providers.

Available as both a web-based tool for instant access and a downloadable desktop application for offline use, providing flexibility in different scenarios, as mentioned in 'Getting started'.
