Struct cipher_crypt::affine::Affine
source · pub struct Affine { /* private fields */ }
Expand description
An Affine cipher.
This struct is created by the new()
method. See its documentation for more.
Trait Implementations§
source§impl Cipher for Affine
impl Cipher for Affine
source§fn new(key: (usize, usize)) -> Affine
fn new(key: (usize, usize)) -> Affine
Initialise an Affine cipher given the key (a
, b
).
Panics
a
orb
are not in the inclusive range1 - 26
.a
has a factor in common with 26.
source§fn encrypt(&self, message: &str) -> Result<String, &'static str>
fn encrypt(&self, message: &str) -> Result<String, &'static str>
Encrypt a message using an Affine cipher.
Examples
Basic usage:
use cipher_crypt::{Cipher, Affine};
let a = Affine::new((3, 7));
assert_eq!("Hmmhnl hm qhvu!", a.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 an Affine cipher.
Examples
Basic usage:
use cipher_crypt::{Cipher, Affine};
let a = Affine::new((3, 7));
assert_eq!("Attack at dawn!", a.decrypt("Hmmhnl hm qhvu!").unwrap());
