Struct cipher_crypt::railfence::Railfence

pub struct Railfence { /* fields omitted */ }

Trait Implementations

impl Cipher for Railfence

type Key = usize

type Algorithm = Railfence

fn new(key: usize) -> Result<Railfence, &'static str>

Initialise a Railfence cipher given a specific key (number of rails).

Will return Err if the key == 0.

fn encrypt(&self, message: &str) -> Result<String, &'static str>

Encrypt a message using a Railfence cipher.

Examples

Basic usage:

use cipher_crypt::{Cipher, Railfence};

let r = Railfence::new(3).unwrap();
assert_eq!("Src s!ue-ertmsaepseeg", r.encrypt("Super-secret message!").unwrap());

fn decrypt(&self, ciphertext: &str) -> Result<String, &'static str>

Decrypt a message using a Railfence cipher.

Examples

Basic usage:

use cipher_crypt::{Cipher, Railfence};

let r = Railfence::new(3).unwrap();
assert_eq!("Super-secret message!", r.decrypt("Src s!ue-ertmsaepseeg").unwrap());
