The chart you showed says the toughest encryption would take 83.5 days to crack at 1 billion passwords per second. Divide your 83.5 / 76.1 = 1.09 days for Project Bovine to crack.
That being said, I am sure that JA is aware of this and using the best possible methods that he is aware of.
Can you run the numbers to see what would happen using the bove parameters?
Besides, the govt. will eventually crack it (probably 4Chan also) to see what it is, if it's legit, then they will know if he is bluffing or going "all in."
Thoughts?
