⏰ Timestamps for content in this video ⏰

00:00 Mathematics of the AES column mixing function MixColumns
01:35 Outline of AES decryption cipher
02:06 Implementing the AES column mixing function MixColumns in Python
09:40 Executing the AES encryption

🔷🔷 About 🔷🔷

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

In this last part, the implementation of the AES function Mix-Columns is demonstrated, which concludes the implementation of the AES encryption cipher.

All code demonstrated serves educational purposes only.
