In this chapter, we will discuss two types of symmetric encryption algorithms, Data Encryption Standard (DES) and Advanced Encryption Standard (AES). The goal of this chapter is to provide a starting point for implementing such algorithms from scratch without using third-party libraries, by using the theoretical concepts and translating them into a practical application using Java.

Data Encryption Standard

This section will describe DES as ...
