An Analysis of Legacy Software Piracy Scene Releases and the Architecture of WinRAR Key Generation
A (or Keygen) is the holy grail of reverse engineering. The group CORE successfully reverse-engineered WinRAR's internal validation algorithm. Instead of butchering the original code, their tool allowed users to type in any name, and the "Keyfilemaker" would mathematically generate a perfectly valid, flawlessly signed rarreg.key file.

Today, WinRAR 3.91 is a relic. WinRAR is currently on version 7.x, featuring much better security and support for modern formats like RAR5.
