So you've got a few supercomputers at your disposal then?
What do you mean rainbow tables don't work? My rainbow tables with all sorts of other nasty shortcuts could bruise down that second password in less than a second. If there are other passwords in the same table its possible to pick up on patterns and exponentially increase the cracking speed.
If you can crack a 20+ character heck, let's go with MD5, hashed password in even an hour, please do record your huge supercomputer farms doing this magical cracking and upload it here so all may see quite how superhuman-like you are.
