Nevermind that the NSA currently is paying telecommunication companies to store our metadata (thanks Snowden!) or that the NSA is subsidizing transoceanic cables (non sarcastic thanks Snowden)
Patent 8,363,825, from 2009, looks at lot like some kind of CRC fuzzy hashing.
Patent 9,525,866, from 2016, is anti-camera forensics. Time to go back to film! (or maybe just resize it to 50% and save it as a rather lossy JPEG)
Patent 7,406,595, from 2004, shows how the NSA encrypts communications. Sounds more efficient than Enchilada, as submitted to CAESAR.
Patent 6,922,774, from 2001, shows what the NSA does with virtual machines.
Patent 6,724,893, from 1996, is about key escrow. If one uses TENS, a version of linux from the US government, one notices that the help manual for the encryption wizard talks about key escow. But all our keys is escrowed since the NSA stole SIM card keys from foreign manufacturers of our devices?
Patent 6,912,284, from 1983 and the longest expiration date, is about some kind of LFSR AEAD cipher. What? They discovered this in 1983 and we're still working on AEAD ciphers?
Patent 6,820,830 appears to be just placing slants under a paper shredder to direct output into multiple rubbish bins.
Like people. You can just go to the NSA's website. This is two clicks away from the front page. What are you people doing? If you're going to be lazy.
