Cracking Windows Cryptography (CryptProtectData)

Eclipse · 04-15-2015, 08:05 PM

I was wondering if there was a way to crack shit encrypted with Windows Cryptography's CryptProtectData? Specifically, the Wifi password within the XML file in which Win7 Wifi passwords are stored.

Brute Forcing is obviously possible (not sure about Python), but I wanted to know if any of you have any specific tips to make the cracking faster and more efficient.
