kryptos::ciphers::substitution

Struct Substitution

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

Substitution Cipher

The struct is generated through the new() function.

Implementations§

Source§

impl Substitution

Source

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

Initializes a substitution cipher with a supplied substitute alphabet.

§Examples
use kryptos::ciphers::substitution::Substitution;

let s = Substitution::new("RBQIZDJCFMELOPAVNHYGWKTUXS").unwrap();
§Errors

Will return Err() if the alphabet is not 26 unique alphabetic characters.

Source

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

Enciphers a message with a substitution cipher.

§Examples
use kryptos::ciphers::substitution::*;

let s = Substitution::new("NAKYQRTXBZPFIVEJSDCHGOUMWL").unwrap();
assert_eq!(
    "Ye weg fbpq cqkdqh iqccntqc",
    s.encipher("Do you like secret messages").unwrap()
);
§Panics

Will panic if there is a missing character or invalid character.

Source

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

Deciphers a message with a substitution cipher.

§Examples
use kryptos::ciphers::substitution::*;

let s = Substitution::new("NAKYQRTXBZPFIVEJSDCHGOUMWL").unwrap();
assert_eq!(
    "Do you like secret messages",
    s.decipher("Ye weg fbpq cqkdqh iqccntqc").unwrap()
);
§Panics

Will panic if there is a missing character or invalid character.
