GPUs, password recovery and thunder tables

April 24, 2008 (at 10:30 a.m.) in Attacks

I’m going to talk about using graphic processors for accelerating cryptographic algorithms and, thus, password recovery. Some information on GPU architecture will be given along with general optimization strategies. Step by step, you’ll see how to build GPU-enabled password cracker from ground up and turn your GeForce into password crunching machine :-)
