Struct ciphers::ColumnarTransposition

pub struct ColumnarTransposition { /* fields omitted */ }

A Columnar Transposition cipher implementation.

Methods

impl ColumnarTransposition

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

Takes the key for the Columnar Transposition cipher and returns a corresponding ColumnarTransposition struct.

Panics

• If key is not valid ascii.

Trait Implementations

impl Cipher for ColumnarTransposition

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

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

Example

use ciphers::{Cipher, ColumnarTransposition};

let ct = ColumnarTransposition::new("GERMAN");

let ctext = ct.encipher("DEFENDTHEEASTWALLOFTHECASTLE");
assert_eq!(ctext.unwrap(), "NALCEHWTTDTTFSEELEEDSOAFEAHL")

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

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

Example

use ciphers::{Cipher, ColumnarTransposition};

let ct = ColumnarTransposition::new("GERMAN");

let ptext = ct.decipher("NALCEHWTTDTTFSEELEEDSOAFEAHL");
assert_eq!(ptext.unwrap(), "DEFENDTHEEASTWALLOFTHECASTLE");
