So all the governments of the whole world, plus the army of crypto-scientists who have yet to crack SHA-256, are on the whole, either less technically adept than the NSA, OR are in on it too.
The NSA's budget is classified for a reason. The NSA's benefactors have access to resources that most of the world cannot even comprehend. I cannot offer proof but I can claim this is a possibility more real than most think. When a national government such as the US helps achieve control of the world's finances and military in less than 2 centuries anything seems possible.
By the way, have you seen the budget of the Department of Defense recently?
