This is a continuation of (DES) The Data Encryption Standard [Part 1], so it is highly encouraged to read that post before reading this post.

Introduction In 1976, Whitfield Diffie and Martin Hellman introduced to the world the concept of public key cryptography also known as asymmetric cryptography.
Motivation In the next few posts I want to discuss the Advanced Encryption Standard or better known as AES, which is the most
The Substitution Cipher We will discuss one of the simplest ciphers, the substitution cipher. This cipher has a lot of historical relevance being
