This project implements the Playfair cipher, a classical symmetric encryption method. The program uses a 5x5 table to encrypt and decrypt messages, where the letter "W" is replaced by "V" and ...

Abstract: nowadays, the need to protect information from various attackers is growing. There are asymmetric cryptographic algorithms that offer a good security rate, but at the same time, they consume ...

Abstract: Quantum computing is generally considered non-threatening to symmetric ciphers. Quantum attacks on symmetric ciphers require a thorough analysis of their internal structures, posing ...

The project involves the implementation of a classic symmetric key encryption, the same key is used for both encryption and decryption. Ceasar Cipher algorithm is used, which employs a single shift ...
