CompTIA Security+ Certification SY0-601: The Total Course - Cryptography Basics

The video tutorial introduces cryptography, focusing on obfuscation, diffusion, and confusion. It explains the Caesar cipher and its limitations, followed by the Vigenère cipher's application. The tutorial then covers binary encryption using XOR and concludes with Kirkoff's principle, emphasizing the importance of algorithms and keys in cryptography.
