pub struct Playfair { /* private fields */ }

Playfair cipher structure, stores data needed during the encryption/decryption

Implementations

impl Playfair

pub fn new(kw: &str) -> Self

Generates a new Playfair cipher structure with the keyword and appropriate alphabet padding to ensure it can fit into the matrix.

pub fn keyword(&self) -> &str

Get a copy of the keyword of the Playfair structure

pub fn update_keyword(&mut self, kw: &str)

Allow updating the current keyword of the Playfair object. This may be useful if you are encrypting and decrypting amonst multiple parties at once, and have numerous different keywords / matricies to operate over.
