Symmetric ciphers

Lecture Cryptography: Modern Symmetric Ciphers (Part 1) focuses on classical symmetric cipher algorithms and introduces modern techniques. The lecture explores block ciphers, stream ciphers, and provides an in-depth analysis of the Data Encryption Standard (DES). This serves as a foundation for understanding advanced symmetric encryption. Please refer to the lecture for more details!

Lecture Cryptography: Modern Symmetric Ciphers (Part 2) delves into the Advanced Encryption Standard (AES) and modes of operation. The lecture explains how AES improves upon previous methods and introduces multiple techniques for secure encryption processing. It also examines how data can be handled in different cipher modes. Please refer to the lecture for more details!
