Hashcat is an excellent tool to use or security audits of passwords. I will be doing a series of articles relating to anything from simple brute forcing such as the article to more complex techniques using Hashcat, oclHashcat, and the Hashcat-gui on both Windows and Linux operating systems. The goal is to make people more aware of the technologies available to crack passwords which should allow people to audit their companies passwords for more strict enforcement. This article relates to using the Hashcat-gui on Windows 7 to crack 10 MD5 hashes and assumes that you already have successfully installed Hashcat and the Hashcat-gui.
I typically use Hashcat and oclHashcat in a Linux environment however I wanted to play around with the Windows version which includes the Hashcat-gui. When attempting to run the Hashcat-gui on my Windows 7 Ultimate 64-bit laptop to brute force a list of MD5 hashes I was receiving an error. The error is described below along with how it was resolved temporarily until a fix can be provided.
