Struct cipher_crypt::fractionated_morse::FractionatedMorse [−][src]
pub struct FractionatedMorse { /* fields omitted */ }
A Fractionated Morse cipher.
This struct is created by the new()
method. See its documentation for more.

impl Cipher for FractionatedMorse
type Key = String
type Algorithm = FractionatedMorse
fn new(key: String) -> Result<FractionatedMorse, &'static str>
[src]
fn new(key: String) -> Result<FractionatedMorse, &'static str>
Initialise a Fractionated Morse cipher given a specific key.
Will return Err
if the key contains non-alphabetic symbols or is empty.
fn encrypt(&self, message: &str) -> Result<String, &'static str>
[src]
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")).unwrap(); assert_eq!("CPSUJISWHSSPFANR", fm.encrypt("AttackAtDawn!").unwrap());
fn decrypt(&self, cipher_text: &str) -> Result<String, &'static str>
[src]
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")).unwrap(); assert_eq!("ATTACKATDAWN!", fm.decrypt("cpsujiswhsspfanr").unwrap());
