Struct ciphers::RunningKey

pub struct RunningKey { /* fields omitted */ }

A Running Key cipher implementation.

Methods

impl RunningKey

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

Takes the key for the Running Key cipher and returns a corresponding RunningKey struct.

Panics

• If key is not alphabetic.

Trait Implementations

impl Cipher for RunningKey

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

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

Example

use ciphers::{Cipher, RunningKey};

let running_key = RunningKey::new("HOWDOESTHEDUCKKNOWTHATSAIDVICTOR");

let ctext = running_key.encipher("DEFENDTHEEASTWALLOFTHECASTLE");
assert_eq!(ctext.unwrap(), "KSBHBHLALIDMVGKYZKYAHXUAAWGM");

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

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

Example

use ciphers::{Cipher, RunningKey};

let running_key = RunningKey::new("HOWDOESTHEDUCKKNOWTHATSAIDVICTOR");

let ptext = running_key.decipher("KSBHBHLALIDMVGKYZKYAHXUAAWGM");
assert_eq!(ptext.unwrap(), "DEFENDTHEEASTWALLOFTHECASTLE");
