(at roughly the current rate) actually the rate at which we are moving through the blocks in increasing. Although we have been going for 608 days, at our current rate it would have taken us 265 days to do the same. Assuming our rate doesn't actually decrease (or increase) it will take us about 6.8 years to check the remaining keyspace. > Tangible timeframe ... long.

However if our rate of checking blocks keeps increasing due to more participants and faster computers it may be a different story. http://rc5stats.distributed.net/rc5-64/ > > In any case, my science background makes me far more interested in doing a > more "traditional" science experiment than cracking encrypted messages > where I can work for years and maybe never do anything but pump out keys. > In SETI, I might not find aliens, but I might find something else of > scientific interest. I was going to try this but am reluctant to swap over half way. To me it is a little like changing aisles at the supermarket. Just as I change lines the one I was in speeds up and the one I moved to slows down. just my .02 Andrew Perry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
