Polygraphia

A comprehensive Rust library for classical and modern cryptographic algorithms.

Features

• Classical Ciphers: Caesar, Affine, Hill, Playfair
• Text Modes: Preserve all characters or alphabetic only
• Key Derivation: PBKDF2-HMAC-SHA512/256
• FFI Support: C-compatible shared library (coming soon!)
• Type-Safe: Leverages Rust's type system for security

Installation

Add to your Cargo.toml:

[dependencies]
polygraphia = "0.1.1"

Quick Start

use polygraphia::classical::Caesar;
use polygraphia::traits::Cipher;

let cipher = Caesar::new(3);
let encrypted = cipher.encrypt("hello")?;
let decrypted = cipher.decrypt(&encrypted)?;

Algorithms

Caesar Cipher

use polygraphia::classical::Caesar;
let cipher = Caesar::new(3);

Affine Cipher

use polygraphia::classical::Affine;
let cipher = Affine::new(5, 8)?;

Playfair Cipher

use polygraphia::classical::Playfair;
let cipher = Playfair::new("secret")?;

Hill Cipher

use polygraphia::classical::Hill;
let cipher = Hill::new("hill")?;
