$begingroup$ An interesting point about some modern standardized ciphers, like AES, is the fact that the government is "ingesting its very own dogfood" through the use of them internally. (AES 192 and 256 are authorized for top-secret info.) Back again within the day (up from the 90s), U.S. govt interior encryption benchmarks wasn't carefully aligned with public sector cryptography, and we mostly experienced to invest as as to if public copyright could hold up to the government requirements; the NSA experienced a history of knowing much more copyright than they Permit on.
