ruption_quantum_encrypt

A quantum-secure encryption crate with hybrid lattice/code-based cryptography and enhanced randomness.

Overview

ruption_quantum_encrypt provides a software-only approach to quantum-secure encryption, combining lattice-based and code-based cryptographic techniques. It includes a unique TrueRandom generator that approximates true entropy using system sources and a quantum-inspired simulation.

Note: This is a toy implementation for demonstration. For production use, replace the simplified algorithms with proper LWE and McEliece implementations.

Features

• Hybrid cryptography for post-quantum security.
• Enhanced randomness with TrueRandom.
• Simple API for key generation, encapsulation, and key derivation.

Installation

Add this to your Cargo.toml:

[dependencies]
ruption_quantum_encrypt = "0.1.0"

## Usage

Generate a keypair, encapsulate a shared secret, and derive keys:

use ruption_quantum_encrypt::{keypair, encapsulate, decapsulate, derive_keys};

let (pk, sk) = keypair();
let (ct, ss1) = encapsulate(&pk);
let ss2 = decapsulate(&ct, &sk);
assert_eq!(ss1.as_bytes(), ss2.as_bytes());

let keys = derive_keys(&ss1, 3);
assert_eq!(keys.len(), 3);
assert_eq!(keys[0].len(), 32);
