impl Vigenere

pub fn new(key: &str) -> Self

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

Trait Implementations

impl Cipher for Vigenere

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

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

Example

use ciphers::{Cipher, Vigenere};

let vigenere = Vigenere::new("FORTIFICATION");

let ctext = vigenere.encipher("DEFENDTHEEASTWALLOFTHECASTLE");
assert_eq!(ctext.unwrap(), "ISWXVIBJEXIGGBOCEWKBJEVIGGQS");

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

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

Example

use ciphers::{Cipher, Vigenere};

let vigenere = Vigenere::new("FORTIFICATION");

let ptext = vigenere.decipher("ISWXVIBJEXIGGBOCEWKBJEVIGGQS");
assert_eq!(ptext.unwrap(), "DEFENDTHEEASTWALLOFTHECASTLE");
