I'm sure you are all aware of the challenges that RSA security set to crack encrypted messages which allows us to understand how secure a specific algorythm is. Distributed.NET works on these projects via means of distributed computing and brute force.
I've worked on previous projects in the past such as RC5-64, back in 1998 and I continued to work on it until completion. I had the advantage of having a lot of machines at college working on the project for me and at the peak I usually had around 5-10,000 blocks a day being submitted for me which all went to the team I was part of (alt.ph.uk). Looking at the stats, I can see that in total I submitted 832,603 blocks, not bad at all.
I've recently started working on RC5-72 now, but this time I have the advantage of using 2 Sun Fire V880's, that both have 8 UltraSPARC-III processors & 32GB of RAM as well as a few other machines P4/Athlon XP based.

That's 8 blocks done in no time already on the one Sun Fire, the same amount are being kicked out on the other Sun Fire too. I wonder if I will be able to get my rate up to the level I had it at in the past? Anyway, if you're interested in joining and helping out by donating your idle CPU cycles then head on over to www.distributed.net - If you want to sumbit your blocks to the team I am part of then join up to Valve Media.
