Implementing DES encryption algorithm in C++

DES Encryption Algorithm in C++

This project is a C++ implementation of the Data Encryption Standard (DES), a symmetric-key algorithm for secure data encryption. It is designed to provide a foundational understanding of encryption mechanisms and showcases how DES operates.

Features

• Encryption and Decryption: Implements core DES functions for data encryption and decryption.
• Modern C++ Standards: Built with C++23, leveraging modern language features for clarity and performance.
• Modular Design: Organized with separate directories for headers and source files for better maintainability.
• Designed as Library: The project is structured to function as a reusable library.

TODOs

• Add functionality to encrypt and decrypt strings.
• Handle file encryption.

Prerequisites

CMake 3.10 or newer. A C++23 compatible compiler.
