## What it is
A C++ tool that generates valid Windows XP and Windows Server 2003 VLK product keys from a raw product key, based on reverse-engineered elliptic curve cryptography from pidgen.dll. It includes research tooling such as a BINK resource reader and documentation of the ECDLP private-key recovery process.

## Use cases
- generate valid windows xp product keys
- recover private keys from pidgen.dll bink resources
- study the windows xp product key activation algorithm
- generate windows server 2003 vlk keys
- learn about elliptic curve discrete logarithm attacks
- archive and preserve legacy windows activation knowledge

## When to choose
- you need to activate legacy Windows XP or Server 2003 installations for retro computing or archival
- you are researching the XP product key algorithm or elliptic curve discrete logarithm problems
- you want a working reference implementation of the XP key generation scheme

## When to avoid
- you need keys for modern, supported Windows versions
- you want a legally sanctioned licensing or activation solution for production systems
- you need a maintained, well-supported tool for enterprise use

## Facets
