XORCryptor Lib
Algorithm for encrypting and decrypting based on XOR bitwise operation
About algorithm
Usage
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);
// or
let res = XORCryptor::new_bytes(key.as_bytes());
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)
);
}
