That makes me think of the current distributed.net project for RC5-72. After nearly three years (1038 days), they are 0.263% complete. If they get lucky they might crack it in the next 30 years, but at the current rate (which would double every six years based upon the project history), I expect it will take them close to 50 years to search the key space. It will take 42 years just to reach the half-way point. That's assuming my estimates and math are accurate.

In all fairness d.net admits they're unlikely to find the key. RC5-72 is pretty much being used as a "default" project if you don't prefer to run OGR. I myself run OGR on d.net.

distributed.net has such a polished client and network, I don't know why more people don't implement their projects on it instead of rolling their own programs and network. The d.net folks always say they're open for project ideas.

Au contraire! However, Bearnol ain't _another_ crank, he's the same old crank.

The first hit from google searching for "bearnol", and a memory of past sci.math posts should explain everything:
