Vigenere Cipher

Implementations

impl Vigenere

pub fn new(key: &'static str) -> Result<Self, String>

Initializes a vigenere cipher with a supplied key.

Examples

use kryptos::ciphers::vigenere::Vigenere;

let v = Vigenere::new("secret").unwrap();

Errors

Will return Err() if the key is not alphabetic.

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

Enciphers a message with a vignere cipher.

Examples

use kryptos::ciphers::vigenere::Vigenere;

let v = Vigenere::new("blaise").unwrap();
assert_eq!(
    "tsh ggy ilvm qsv hhqktfc",
    v.encipher("shh you have you whisper").unwrap()
);

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

Deciphers a message with a vignere cipher.

Examples

use kryptos::ciphers::vigenere::Vigenere;

let v = Vigenere::new("blaise").unwrap();
assert_eq!(
    "whispering can still be heard by others",
    v.decipher("xsiahistno ueo dtqdp cp hmsve my wllfcs").unwrap()
);
