Struct ciphers::Porta

pub struct Porta { /* fields omitted */ }

A Porta cipher implementation.

Methods

impl Porta

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

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

Panics

• If key is not alphabetic.

Trait Implementations

impl Cipher for Porta

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

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

Example

use ciphers::{Cipher, Porta};

let porta = Porta::new("FORTIFICATION");

let ctext = porta.encipher("DEFENDTHEEASTWALLOFTHECASTLE");
assert_eq!(ctext.unwrap(), "SYNNJSCVRNRLAHUTUKUCVRYRLANY");

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

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

Note that the Porta cipher is reciprocal.

Example

use ciphers::{Cipher, Porta};

let porta = Porta::new("FORTIFICATION");

let ptext = porta.decipher("SYNNJSCVRNRLAHUTUKUCVRYRLANY");
assert_eq!(ptext.unwrap(), "DEFENDTHEEASTWALLOFTHECASTLE");
