Advanced Encryption Standard

Project1AES runs the AES protocol on a 128-, 192-, and 256-bit keys in Python.

Dependencies

• Python 3

Instructions

Program prints to the terminal. To redirect output to a file:

python3 Project1AES.py > output.txt

To check it against appendix_c.txt:

vimdiff output.txt appendix_c.txt

The only differences between the two files is the lack of the Equivalent Inverse Cipher sections, which was not implemented.
