Struct cipher_crypt::scytale::Scytale

pub struct Scytale { /* fields omitted */ }

A Scytale cipher.

This struct is created by the new() method. See its documentation for more.

Trait Implementations

impl Cipher for Scytale

type Key = usize

type Algorithm = Scytale

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

Initialize a Scytale cipher with a specific cylinder height.

Will return Err if the key == 0.

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

Encrypt a message using a Scytale cipher.

Whilst all characters (including utf8) can be encrypted during the transposition process, it is important to note that the space character is also treated as padding. As such, whitespace characters at the end of a message are not preserved during the decryption process.

Examples

Basic usage:

use cipher_crypt::{Cipher, Scytale};

let s = Scytale::new(6).unwrap();
assert_eq!("Pegr lefoporaryr !", s.encrypt("Prepare for glory!").unwrap());

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

Decrypt a message using a Scytale cipher.

Examples

Basic usage:

use cipher_crypt::{Cipher, Scytale};

let ct = Scytale::new(6).unwrap();
assert_eq!("Prepare for glory!", ct.decrypt("Pegr lefoporaryr !").unwrap());
