The point I was trying to make is that complexity is not in encrypt() and decrypt(). Those things can be very simple, yet cryptographically strong. Complexity

Complexity begins when you try doing something more involved than just symmetric block encryption.
- tptacek 10y agoIf by "symmetric block encryption" you mean "use the block permutation of the cipher directly", then nobody ever does that; the people who make the mistake of using the cipher's "Encrypt" and "Decrypt" are the ones who end up discovering that the default mode of a cipher is ECB. I think I sort of see your point, but SPECK is a weird recommendation.
