Trait Implementations

impl Cipher for Caesar

type Key = usize

type Algorithm = Caesar

fn new(shift: usize) -> Result<Caesar, &'static str>

Initialise a Caesar cipher given a specific shift value.

Will return Err if the shift value is outside the range 1-26.

fn encrypt(&self, message: &str) -> Result<String, &'static str>

Encrypt a message using a Caesar cipher.

Examples

Basic usage:

use cipher_crypt::{Cipher, Caesar};

let c = Caesar::new(3).unwrap();
assert_eq!("Dwwdfn dw gdzq!", c.encrypt("Attack at dawn!").unwrap());

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

Decrypt a message using a Caesar cipher.

Examples

Basic usage:

use cipher_crypt::{Cipher, Caesar};

let c = Caesar::new(3).unwrap();
assert_eq!("Attack at dawn!", c.decrypt("Dwwdfn dw gdzq!").unwrap());
