1024 bit wide keys sheesh, the keyrate on an Athlon 1.5ghz would suck soooo bad, I wonder if it could even check a single 1024 bit key in less than a second. not to mention theres 97453140113999990803533823878751000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 times more keys than there are in RC5-64 (yes, thats an exact number from my calculator)
