Applied Cryptography C1: Introduction - Basic Cryptology Terminology (Lecture)

#cryptology, #cryptography, #cryptanalysis Welcome to the first video in my new series, "Applied Cryptography." This series is based directly on the university lecture Angewandte Kryptografie ("Applied Cryptography") that I teach at Cyber Campus NRW of the university of applied sciences (Hochschule) Niederrhein. The course content has been translated 1:1 from German, so some expressions on the slides may occasionally sound unusual in English. Throughout this series, we will explore the fundamentals of cryptology—including both cryptography and cryptanalysis—from its classical roots to modern-day applications. We'll look at key concepts such as ciphers, encryption, decryption, key exchange, and historical milestones that shaped the development of secure communication. To bring cryptographic techniques to life, we will make practical use of tools like CrypTool and OpenSSL, demonstrating how cryptographic operations can be implemented and analyzed in real-world scenarios. Whether you're a student, developer, or security enthusiast, I hope you find this series both educational and engaging.
