Struct ciphers::Autokey

pub struct Autokey { /* fields omitted */ }

An Autokey cipher implementation.

Methods

impl Autokey

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

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

Panics

• If key is not alphabetic.

Trait Implementations

impl Cipher for Autokey

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

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

Example

use ciphers::{Cipher, Autokey};

let autokey = Autokey::new("FORTIFICATION");

let ctext = autokey.encipher("DEFENDTHEEASTWALLOFTHECASTLE");
assert_eq!(ctext.unwrap(), "ISWXVIBJEXIGGZEQPBIMOIGAKMHE");

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

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

Example

use ciphers::{Cipher, Autokey};

let autokey = Autokey::new("FORTIFICATION");

let ptext = autokey.decipher("ISWXVIBJEXIGGZEQPBIMOIGAKMHE");
assert_eq!(ptext.unwrap(), "DEFENDTHEEASTWALLOFTHECASTLE");
