A project that explains and implements the principle of WinRAR license key generation.
Core Features
Explains the underlying principle of WinRAR license key generation.
Generates WinRAR license files (rarreg.key and rarkey.rar).
Supports multiple encoding types for license details (ASCII, ANSI, UTF8NoBOM).
Offers various methods for usage, including GUI, GitHub Actions, and building from source.
Detailed Introduction
WinRAR is a widely used commercial file archiver. This project delves into the cryptographic and algorithmic mechanisms behind the generation of WinRAR's license files, specifically 'rarreg.key'. It not only provides a detailed explanation of this reverse-engineered process but also offers practical tools to generate these license files. The project supports different character encodings for license information and provides flexible usage options, from a standalone GUI application to integration with GitHub Actions or building directly from source code using Visual Studio or CMake, aiming to demystify WinRAR's licensing.
