(C++) XOR Operation by Thomas Roccia
Created the Tuesday 13 December 2022. Updated 9 months, 2 weeks ago.
Description:
The original message is first converted to binary format using the string data type. The key is also converted to binary format using the same type. The XOR operation is then performed on the binary message using the binary key. The resulting ciphertext is then concatenated to a string and printed to the screen. This ciphertext can then be decrypted using the same key to access the original message.
Code
#include <iostream>
#include <string>
using namespace std;
int main()
{
// Define the key to use for the XOR operation
string key = "mysecretkey";
// Define the original message to be encrypted
string message = "Hello, world!";
// Convert the key and message to binary format
string binary_key = key;
string binary_message = message;
// Perform the XOR operation on the binary message using the binary key
string ciphertext = "";
for (int i = 0; i < binary_message.length(); i++)
{
ciphertext += binary_message[i] ^ binary_key[i % binary_key.length()];
}
// Print the resulting ciphertext
cout << ciphertext << endl;
return 0;
}
