Simple letter substitution cipher 🔐️
Features
- ROT encryption & decryption
Usage
use nrot::{rot13, rot13_letter, Mode};
fn encrypt(input: String) {
let input_length = input.len();
let input_bytes = input.as_bytes();
if input_length == 1 {
let byte_result = rot13_letter(Mode::Encrypt, input_bytes[0]);
println!("{}", String::from_utf8_lossy(&[byte_result]))
} else {
let bytes_result = rot13(Mode::Encrypt, input_bytes);
println!("{}", String::from_utf8_lossy(&bytes_result))
};
}
fn decrypt(input: String) {
let input_length = input.len();
let input_bytes = input.as_bytes();
if input_length == 1 {
let byte_result = rot13_letter(Mode::Decrypt, input_bytes[0]);
println!("{}", String::from_utf8_lossy(&[byte_result]))
} else {
let bytes_result = rot13(Mode::Decrypt, input_bytes);
println!("{}", String::from_utf8_lossy(&bytes_result))
};
}
fn main() {
let input = "Hello, world!".to_string();
encrypt(input);
let input = "Uryyb, jbeyq!".to_string();
decrypt(input);
}
