Nice write up on CNET about the agencies and they tools they are likely using to gather up and crack the data on Bin Laden’s computers. If extreme care was taken by the terrorists this could be an extremely difficult job. But maintaining absolute security of data over long periods of time is extremely difficult. The human factor usually provides some easy doors for cracking even encrypted data so I suspect they can process the data pretty quickly.
