Cryptographic Algorithms: Theoretical Foundations and Practical Application for Secure Digital Communication

Abstract

The project compares a group of popular algorithms from different categories, including encryption and hashing. Through research and speed tests, it looks at these methods’ performance, security, speed, best use cases. The comparison helps to better understand how these tools operate to protect information in everyday digital activities. The goal of this comparative study is to understand why certain older algorithms have been replaced by newer ones, and to give a clear picture of which algorithms are most suitable for current and future digital security needs.
