"The leaked documents" is as much detail as the article goes into. Given the history of reporting on this matter and the walking back done on all the original leaks, color me skeptical its as dramatic as it sounds and not what I said: the NSA engages in a bunch of spycraft since encryption is based on trust, trust is easy to compromise, but again: I'll bet AES encryption has no easily exploitable weaknesses, and SSL is completely secure provided you don't need to use the root chain of trust associations which all ultimately wind up at "the government".
