Trait Implementations§
source§impl Cipher for Caesar
impl Cipher for Caesar
source§fn new(shift: usize) -> Caesar
fn new(shift: usize) -> Caesar
Initialise a Caesar cipher given a specific shift value.
Panics
shift
is not in the inclusive range1 - 26
.
source§fn encrypt(&self, message: &str) -> Result<String, &'static str>
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);
assert_eq!("Dwwdfn dw gdzq!", c.encrypt("Attack at dawn!").unwrap());
source§fn decrypt(&self, ciphertext: &str) -> Result<String, &'static str>
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);
assert_eq!("Attack at dawn!", c.decrypt("Dwwdfn dw gdzq!").unwrap());
