kryptos::ciphers::caesar

Struct Caesar

Source
pub struct Caesar { /* private fields */ }
Expand description

Caesar Cipher

The struct is generated through the new() function.

Implementations§

Source§

impl Caesar

Source

pub fn new(rot: u8) -> Result<Self, String>

Initializes a caesar cipher with a supplied rotation.

§Examples
use kryptos::ciphers::caesar::Caesar;

let c = Caesar::new(13).unwrap();
§Errors

Will return Err() if the rotation is not between 1 and 26.

Source

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

Enciphers a message with a caesar cipher.

§Examples
use kryptos::ciphers::caesar::Caesar;

let c = Caesar::new(13).unwrap();
assert_eq!("guvf vf n frperg", c.encipher("this is a secret").unwrap());
Source

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

Deciphers a message with a caesar cipher.

§Examples
use kryptos::ciphers::caesar::Caesar;

let c = Caesar::new(10).unwrap();
assert_eq!("this is a secret", c.decipher("drsc sc k combod").unwrap());
