very cool. i'm also hijacking your thread to talk about elcomsoft's distributed password cracker that uses GPUs to do the cracking. anyone used this yet?http://elcomsoft.com/edpr.html
"Elcomsoft Distributed Password Recovery employs a revolutionary, patent pending technology to accelerate password recovery when a compatible NVIDIA graphics card is present in addition to the CPU-only mode. Currently supporting all GeForce8 boards, the acceleration technology offloads parts of computational-heavy processing onto the fast and highly scalable processors featured in the NVIDIA’s latest graphic accelerators.
The acceleration technology developed by ElcomSoft allows the execution of mathematically intensive password recovery code on the massively parallel computational elements found in latest NVIDIA graphic accelerators. The GPU acceleration is unique to Elcomsoft Distributed Password Recovery, making password recovery up to twenty times faster
compared to password recovery methods that only use the computer’s main CPU."
of course, with passing the hash there is really no reason to crack passwords anymore
