What you’re now suggesting is very close to conspiracy territory. Most cryptosystems are developed outside the government. Moreover, if you look at the authors of many of the most prominent cryptographic primitives, they aren’t exactly fans of the NSA. Do you think that the NSA has backdoored the algorithms to the extent that the entirety of academia is in on it? That’s what it would take for what you’re suggesting to be true, because there’s a huge incentive to catch this if it’s occurring.
