Block Cipher vs. Stream Cipher Explained 🔐 | Cryptography Basics

Welcome back. In this video you will learn the basic concepts of block cipher and stream cipher. The explanation is made easy and understandable with a simple demonstration. Block cipher uses confusion and diffusion for the encryption process, while stream cipher uses only confusion. Hence, for better comprehension of the block cipher and stream cipher, I recommend you to watch my previous video on confusion and diffusion. The link of the video on confusion and diffusion is given below https://www.youtube.com/watch?v=U4SmJ4QJ1OE
