Symmetric cryptography

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!
