## Health v2 (maintenance only)
Score: 96/100 (v2, computed 2026-09-03T02:39:23.370411+00:00)
- activity 96, release rhythm 94, longevity 100
- inputs: {"age_days": 2215, "days_push": 26, "days_rel": 43, "gap_med": 20.0, "n_releases_24m": 7}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
An open-source tool and educational write-up explaining the principle behind WinRAR's 'rarreg.key' license file generation, with implementations in C++ buildable via Visual Studio, CMake, or GitHub Actions. It includes a Windows WPF GUI and supports ASCII, ANSI, and UTF-8 (No BOM) encodings.

## Use cases
- understand how WinRAR license keys are generated
- generate a rarreg.key file for WinRAR
- study the WinRAR keygen algorithm in C++ source code
- build a keygen with CMake or Visual Studio
- generate license files via GitHub Actions workflows
- use a GUI tool on Windows to produce WinRAR license files

## When to choose
- you want to learn the cryptographic principle behind WinRAR license file generation
- you need a reproducible, scriptable way to generate rarreg.key files across platforms
- you prefer building from source with CMake or Visual Studio

## When to avoid
- you want a legally licensed copy of WinRAR - buy a license from RARLAB instead
- you need a general-purpose archive tool rather than a license-file generator
- you cannot accept the legal risk of using license circumvention tools on commercial software
