XORCryptor Lib

Algorithm for encrypting and decrypting based on XOR bitwise operation

About algorithm

Usage

For 64 bit CPU:

use xor_cryptor::XORCryptor;

fn main() {
    let sample_text = String::from("Hello World !");
    let key = String::from("secret_key");
    let buffer = sample_text.as_bytes().to_vec();

    let res = XORCryptor::new(&key);
    if res.is_err() {
        return;
    }
    let xrc = res.unwrap();

    let encrypted_buffer = xrc.encrypt_vec(buffer);
    let encrypted_string = String::from_utf8_lossy(&encrypted_buffer);
    println!("Encrypted: {}\n", encrypted_string);

    // This encrypted string contains formatted non-utf8 characters
    // Do not use this string as vector to decrypt
    let decrypted_buffer = xrc.decrypt_vec(encrypted_string.as_bytes().to_vec());
    println!(
        "Decrypted from string : {:?}",
        String::from_utf8_lossy(&decrypted_buffer)
    );

    let decrypted_buffer = xrc.decrypt_vec(encrypted_buffer);
    println!(
        "Decrypted from vec    : {:?}",
        String::from_utf8_lossy(&decrypted_buffer)
    );
}

For rest:

use xor_cryptor::XORCryptor;

fn main() {
   let sample_text = String::from("Hello World !");
   let key = String::from("secret_key");

   let mut buffer = sample_text.as_bytes().to_vec();
   let res = XORCryptor::new(&key);
   if res.is_err() {
       return;
   }
   let xrc = res.unwrap();
   xrc.encrypt_vec(&mut buffer);

   let encrypted_string = String::from_utf8_lossy(&buffer);
   println!("Encrypted: {}\n", encrypted_string);

   // This encrypted string contains formatted non-utf8 characters
   // Do not use this string as vector to decrypt
   let mut d_buff = encrypted_string.as_bytes().to_vec();
   xrc.decrypt_vec(&mut d_buff);
   println!("Decrypted from string : {:?}", String::from_utf8_lossy(&d_buff));

   xrc.decrypt_vec(&mut buffer);
   println!("Decrypted from vec    : {:?}", String::from_utf8_lossy(&buffer));
}
