# AES Playground
My experiments in understanding AES, Whitebox AES, and related attacks.
See `textbook_aes.py` and the contents of the `aes/` subdirectory for an AES128
implementation, which maps as closely to the FIPS 197 spec as possible.
### DISCLAIMER: This code is optimised for educational purposes. Do not use in a security context.
My goals are to:
- Implement textbook AES from first principles.
- Implement LUT-based AES.
- Try extracting keys from the LUTs.
- Replicate academic Whitebox AES implementations.
- Implement known attacks, from first principles.
- Invent/implement novel attacks! (can "Differential Fault Analysis Using Symbolic Execution" be applied to whitebox/LUT based implementations?)
