⏰ Timestamps for content in this video ⏰

00:00 Introducing NIST SP 800-38D as official Galois/Counter Mode (GCM) standardization document
01:41 Setting up the AES-GCM implementation in Python using official NIST test vectors
05:38 Implementing the GCM authenticated encryption function in Python

🔷🔷 About 🔷🔷

This Fundamental Cryptography in Theory and Python lesson is the 1st of 2 parts demonstrating, how AES-GCM can be implemented in Python straight out of the official standardization document NIST SP 800-38D which defines the Galois/Counter Mode (GCM) block cipher mode of operation.

In this first part, the implementation of AES-GCM is set up with a driver using official NIST test vectors, and the implementation of the GCM authenticated encryption function is demonstrated.

All code demonstrated serves educational purposes only.
