Rainbowtables re-implemented

Presented at REcon 2010, July 10, 2010, 5:20 p.m. (60 minutes).

Over the last few years rainbow-tables have started to disappear. Torrents didn't get seeded anymore, mirrors went down. So we wondered why that happened and what mistakes have been made in the past. With more and more graphics cards adding support for running own code on their gpu's one has to ask himself is there still a need for rainbow-tables. Does the memory over time tradeoff still meet the requirements of modern day computing? Taking a closer look, one quickly realises the reduction function used by tools such as rainbow-crack and rcracki doesn't scale well on gpu's. There are also a few things that aren't as good as they could be with the current table implementations. So we decided to give it another go. Re- Think, Re- Plan, Re- write in oder to meet the new challenges of gnu computing.
