## 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);

}

```
