pub struct FractionatedMorse { /* private fields */ }
Expand description
A Fractionated Morse cipher.
This struct is created by the new()
method. See its documentation for more.
Trait Implementations§
source§impl Cipher for FractionatedMorse
impl Cipher for FractionatedMorse
source§fn new(key: String) -> FractionatedMorse
fn new(key: String) -> FractionatedMorse
Initialise a Fractionated Morse cipher given a specific key.
Panics
- The
key
is empty. - The
key
contains a non-alphabetic symbol.
source§fn encrypt(&self, message: &str) -> Result<String, &'static str>
fn encrypt(&self, message: &str) -> Result<String, &'static str>
Encrypt a message using a Fractionated Morse cipher.
Morse code supports the characters a-z
, A-Z
, 0-9
and the special characters
@ ( ) . , : ' " ! ? - ; =
. This function will return Err
if the message contains any
symbols that do not meet this criteria. As morse code does not preserve case, all messages
will be transposed to uppercase automatically.
Examples
Basic usage:
use cipher_crypt::{Cipher, FractionatedMorse};
let fm = FractionatedMorse::new(String::from("key"));;
assert_eq!("CPSUJISWHSSPFANR", fm.encrypt("AttackAtDawn!").unwrap());
source§fn decrypt(&self, cipher_text: &str) -> Result<String, &'static str>
fn decrypt(&self, cipher_text: &str) -> Result<String, &'static str>
Decrypt a message using a Fractionated Morse cipher.
The Fractionated Morse alphabet only contains the normal alphabetic characters a-z
,
therefore this function will return Err
if the message contains any non-alphabetic
characters. Furthermore, it is possible that a purely alphabetic message will not produce
valid Morse code, in which case an Err
will again be returned.
Examples
Basic usage:
use cipher_crypt::{Cipher, FractionatedMorse};
let fm = FractionatedMorse::new(String::from("key"));;
assert_eq!("ATTACKATDAWN!", fm.decrypt("cpsujiswhsspfanr").unwrap());
