nROT

Simple letter substitution cipher 🔐️

Features

• ROT encryption & decryption
• Exhaustive testing

Usage

``` rust use nrot::{rot, rot_letter, Mode};

fn encrypt(input: String) { let rotation = 13;

let input_length = input.len();
let input_bytes = input.as_bytes();

if input_length == 1 {
    let byte_result = rot_letter(Mode::Encrypt, input_bytes[0], rotation);
    println!("{}", String::from_utf8_lossy(&[byte_result]))
} else {
    let bytes_result = rot(Mode::Encrypt, input_bytes, rotation);
    println!("{}", String::from_utf8_lossy(&bytes_result))
};

}

fn decrypt(input: String) { let rotation = 13;

let input_length = input.len();
let input_bytes = input.as_bytes();

if input_length == 1 {
    let byte_result = rot_letter(Mode::Decrypt, input_bytes[0], rotation);
    println!("{}", String::from_utf8_lossy(&[byte_result]))
} else {
    let bytes_result = rot(Mode::Decrypt, input_bytes, rotation);
    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);

} ```
