My real motivation was looking around for the best way to do descrypt on readily available FPGAs with JtR. Parallella would also be attractive if the price/performance was on par with the ztex-bruteforcer work (960Mh/s at 40W), or at least significantly ahead of GPU. In my ideal world, I'd like to chip in with others to sponsor JtR work on what might be called descrypt-ztex or descrypt-parallella. I'm just a solo researcher on this one, but since there looks like a lot of potential, I could chip in more than lunch money. :-) The obvious problem is that most folks aren't super-interested in descrypt. It does seem to make a good first port to a new platform, so it will almost certainly happen, but it's not likely to inspire a Kickstarter, etc. Royce
