Comparative Analysis of Symmetric Cryptographic Algorithms and Cryptanalysis Methods Through a Practical Software Tool for Educational Purposes †

Abstract

This paper presents the design and evaluation of an educational software tool aimed at facilitating the practical exploration of symmetric cryptographic algorithms. The application integrates widely used algorithms, including AES, DES, TripleDES, RC2, Blowfish, Twofish, and Camellia, allowing users to perform encryption, decryption, and cryptanalysis via dictionary and brute-force attacks. It provides performance benchmarking by measuring encryption and decryption speed, computational overhead, throughput, and resistance to attacks. Visual elements such as real-time charts and histograms aid in comparing algorithmic behavior. The tool is tailored for educational use, supporting cybersecurity and computer science students in understanding cryptographic principles, algorithm effectiveness, and cryptanalytic techniques. Its goal is to bridge theory and practice in a user-friendly and interactive manner, promoting deeper engagement with modern cryptographic methods.
