Implementations

impl Caesar

pub fn new(rotation: u8) -> Result<Caesar, &'static str>

Initialize a caesar cipher with a rotation.

Examples:

use cienli::ciphers::caesar::Caesar;
let caesar = Caesar::new(5).unwrap();

Errors:

The rotation must be in range 1 and 26.

pub fn encipher(&self, message: &str) -> String

Enciphers a message with the caesar cipher.

Examples:

• Encipher with five times rotation:

use cienli::ciphers::caesar::Caesar;
let caesar = Caesar::new(5).unwrap();

assert_eq!("Mjqqt, Ymnx Nx F Yjxy", caesar.encipher("Hello, This Is A Test"));

pub fn decipher(&self, message: &str) -> String

Deciphers a cipher with the caesar cipher.

Examples:

• Decipher with five times rotation:

use cienli::ciphers::caesar::Caesar;
let caesar = Caesar::new(5).unwrap();

assert_eq!("Hello, This Is A Test", caesar.decipher("Mjqqt, Ymnx Nx F Yjxy"));
