Ah, good hint, I found n...@home, a project to factor large integers... There is also eni...@home, but that is a bit old fashioned ;) I think I'll stay with fold...@home >> thing is breaking RSA-2048 would require about 10.000.000 times more >> power than breaking RSA-1024, which -so far as we know- has not been >> broken yet > > Off by about a factor of 100 there.
