Struct ciphers::Caesar

pub struct Caesar { /* fields omitted */ }

A Caesar cipher implementation.

Methods

impl Caesar

pub fn new(key: u8) -> Self

Takes the key for the Caesar cipher and returns a corresponding Caesar struct.

Trait Implementations

impl Cipher for Caesar

fn encipher(&self, ptext: &str) -> CipherResult

Enciphers the given plaintext (a str reference) using the Caesar cipher and returns the ciphertext as a CipherResult.

Example

use ciphers::{Cipher, Caesar};

let caesar = Caesar::new(1);

let ctext = caesar.encipher("DEFENDTHEEASTWALLOFTHECASTLE");
assert_eq!(ctext.unwrap(), "EFGFOEUIFFBTUXBMMPGUIFDBTUMF");

fn decipher(&self, ctext: &str) -> CipherResult

Deciphers the given ciphertext (a str reference) using the Caesar cipher and returns the plaintext as a CipherResult.

Example

use ciphers::{Cipher, Caesar};

let caesar = Caesar::new(1);

let ptext = caesar.decipher("EFGFOEUIFFBTUXBMMPGUIFDBTUMF");
assert_eq!(ptext.unwrap(), "DEFENDTHEEASTWALLOFTHECASTLE");
