Good statistic! You could shrink that number significantly if you equipped those computers with Nvidia graphics cards and off boarded the computation to them. But still, there is no way we are going to get past the encryption. 10^18 or 10^17 years are still a lot and definitely not worth it.

I don't remember how the PDF's are encrypted (Probably the highest level), but the lowest level of encryption can be broken in a day or two.
