FPGAs (Field Programmable Gate Arrays) are slowly becoming more and more advanced and practical as high-speed computing platforms. In this talk, David will provide an in-depth introduction into the guts and capabilities of modern day FPGAs and show how you can take your current algorithms and efficiently convert them to gate logic and run them on hardware. This presentation will also introduce a set of open source cores (jawn v1.0) that will implement the basic functionality of john the ripper on FPGAs and allow you to crack password hashes as fast as 100+ PCs using FPGA PCMCIA cards on your laptop.
