Cryptographic algorithm DES Electronic Code Book mode

The algorithm allows you to encrypt and decrypt the message.

How to use

You need to import the Cipher.h file, create an instance of the Cipher class.

File: main.cpp

#include <ctime>
#include <iostream>
#include <cstdlib>

#include "Cipher.h"


int main()
{
   system("chcp 1251");
   srand(time(nullptr));

   Cipher cipher;
   std::cout << "Input text: ";
   std::string text;
   std::getline(std::cin, text);

   Cipher::PairTxtKey pair = cipher.Encrypt(text);
   std::cout << "Encrypted text: " << pair.txt << std::endl;

   std::string srcText = cipher.Decrypt(pair);
   std::cout << "Decrypted text: " << srcText;
}
