GPU Password Cracking – Bruteforceing a Windows Password Using a Graphic Card


Vijay's Tech Encounters

GPGPU computing is getting lots of attention these days. GPGPU computing simply means doing general calculations on graphic cards (GPUs) rather than CPUs. Traditionally, GPUs were used only for getting graphical output, rendering frames in games and other purposes related to graphics. Lately, people started realizing that GPUs are far more efficient at handling highly parallel tasks and that there should be a way to code for graphic cards. Though GPGPU computing is still at its infancy, a lot of progress has been made toward this direction. For example GPUs are used to speed up video conversion, video processing, doing scientific calculations, folding and password hash cracking.

The last one – password cracking looks very interesting and we are going to discuss about just that. Recently I came across a free password hash cracker called ighashgpu. This tool is developed by a guy called Ivan Golubev. It’s a…
