[−][src]Struct ciphers::FourSquare
A Four-Square cipher implementation.
Methods
impl FourSquare
[src]
pub fn new(key1: &str, key2: &str, alphabet: &str, pad: char) -> Self
[src]
Takes the two keys for the Four-Square cipher and returns a corresponding FourSquare struct.
Panics
- If
alphabet
is not 25 chars in length. - If
alphabet
is not valid ascii. - If
alphabet
contains repeated chars. - If
key1
is not 25 chars in length. - If
key1
contains repeated chars. - If any of the chars in
key1
are not contained inalphabet
. - If
key2
is not 25 chars in length. - If
key2
contains repeated chars. - If any of the chars in
key2
are not contained inalphabet
. - If
pad
is not contained inalphabet
.
Trait Implementations
impl Cipher for FourSquare
[src]
fn encipher(&self, ptext: &str) -> CipherResult
[src]
Enciphers the given plaintext (a str reference) using the Four-Square
cipher and returns the ciphertext as a CipherResult
.
Example
use ciphers::{Cipher, FourSquare}; let four_square = FourSquare::new( "ZGPTFOIHMUWDRCNYKEQAXVSBL", "MFNBDCRHSAXYOGVITUEWLQZKP", "ABCDEFGHIKLMNOPQRSTUVWXYZ", 'X', ); let ctext = four_square.encipher("ATTACKATDAWN"); assert_eq!(ctext.unwrap(), "TIYBFHTIZBSY");
fn decipher(&self, ctext: &str) -> CipherResult
[src]
Deciphers the given ciphertext (a str reference) using the Four-Square
cipher and returns the plaintext as a CipherResult
.
Example
use ciphers::{Cipher, FourSquare}; let four_square = FourSquare::new( "ZGPTFOIHMUWDRCNYKEQAXVSBL", "MFNBDCRHSAXYOGVITUEWLQZKP", "ABCDEFGHIKLMNOPQRSTUVWXYZ", 'X', ); let ptext = four_square.decipher("TIYBFHTIZBSY"); assert_eq!(ptext.unwrap(), "ATTACKATDAWN");
