Public-key cryptography - the RSA cryptosystem

Abstract

This paper‘s main goal is to deliver an accurate image on the concepts of data security and cryptography, by presenting the theory and by developing the application of a fundamental public-key cryptosystem used nowadays, namely the RSA cryptosystem. To prove the usefulness and power of public-key cryptography from a practical standpoint, a software application has been designed, that implements every algorithm inherent to the process of securing data (primes generation, key generation, encryption and decryption).
