This is my "textbook" implementation of AES128, which follows the FIPS specification as closely as possible (in python): https://github.com/DavidBuchanan314/aes-playground

It also includes from-scratch Galois field arithmetic functions.

Looks really nice and educational. I'm a big fan of reeinventing the wheel for understanding certain primitives better. I did the same for ECC. Once it's done it's really liberating because you don't have to consider these things black magic anymore.
