pub struct Scytale { /* private fields */ }

Scytale Cipher

The struct is generated through the new() function.

Implementations

impl Scytale

pub fn new(height: usize) -> Result<Self, String>

Initializes a scytale cipher with a supplied height.

Examples

use kryptos::ciphers::scytale::Scytale;

let s = Scytale::new(4).unwrap();

Errors

Will return Err() if the key is zero.

pub fn encipher(&self, plaintext: &str) -> Result<String, String>

Enciphers a message with a scytale cipher.

Examples

use kryptos::ciphers::scytale::Scytale;

let s = Scytale::new(6).unwrap();
assert_eq!("I r aeh tas ve ec ", s.encipher("I have a secret").unwrap());

Errors

Will return an error if the height is greater than the length of the text

pub fn decipher(&self, ciphertext: &str) -> Result<String, String>

Deciphers a message with a scytale cipher.

Examples

use kryptos::ciphers::scytale::Scytale;

let s = Scytale::new(6).unwrap();
assert_eq!("I have a secret", s.decipher("I r aeh tas ve ec ").unwrap());

Errors

Will return an error if the height is greater than the length of the text
