This video discusses the Simplified DES algorithm with an example. This is a good place to start learning the DES algorithm for cryptography.
Simplified DES (SDES) is a lightweight version of the Data Encryption Standard (DES) designed for educational purposes. It operates on 8-bit blocks instead of 64-bit blocks, making it easier to understand and implement while demonstrating the principles of block cipher encryption.
