Quickpost: Windows 7 Beta: ROT13 Replaced With Vigenère? Great Joke!

Filed under: Encryption,Entertainment,Forensics,Quickpost,Windows 7 — Didier Stevens @ 23:17

Remember that the UserAssist keys are encrypted with ROT13?

In Windows 7 Beta, not anymore! Weak ROT13 crypto has been replaced with “stronger” Vigenère crypto!

The Vigenère key I found through some basic cryptanalysis is BWHQNKTEZYFSLMRGXADUJOPIVC.

To the Microsoft developer who designed this: great joke! You really made me laugh. Seriously. 😎

And I thought Easter Eggs were banned in Microsoft products. Maybe you don’t think of it as an Easter Egg, but as a programmer, I do. 😉
