Crypto 101 – Classical Cryptography

Hi and welcome to this new video! In this video I discuss the main idea behind cryptography, the difference between cryptography and steganography, and what characterized classical ciphers. In the future video of the series I will discuss about modern cryptography and modern cryptographic primitives. I hope you find it helpful, and I would appreciate if you leave your feedback down in the comments, subscribe to the channel and share this series with like-minded people.
