create a software in python that can encrypt and decrypt in cipher block chaining mode using one of the following ciphers : affine modulo 256, Hill modulo 256, S-DES,DES. Test data for S-DES using a ...
This repository contains implementations of basic cryptographic ciphers as part of the Security Protocols course at Tampere University. The tasks cover encryption, decryption, and cryptanalysis of ...
Abstract: Affine Cipher is the development of Classic Caesar cipher that multiplies plain text before shifting operation. Affine cipher has two parameters namely key a, and b. Key ‘a’ is multiplies ...
