⏰ Timestamps for content in this video ⏰

00:00 Implementing the AES adding of round key function AddRoundKey in Python
02:50 Implementing the AES byte substitution function SubBytes in Python
03:54 Implementing the AES row shifting function ShiftRows in Python

🔷🔷 About 🔷🔷

This Fundamental Cryptography in Theory and Python lesson is the 4th of 5 parts demonstrating, how AES can be implemented in Python straight out of its official standardization document NIST FIPS 197.

In this part, the implementation of the AES functions Add-Round-Key, Sub-Bytes and Shift-Rows is demonstrated.

All code demonstrated serves educational purposes only.
