CryptGuard programming library

Introduction

CryptGuardLib is a Rust library providing robust encryption and decryption functionalities. Utilizing advanced cryptographic algorithms, including the post-quantum Kyber1024, it's designed to secure data against quantum-computing threats. This library is ideal for developers looking to integrate strong cryptographic features into their Rust applications.

Prerequisites

To use CryptGuardLib, ensure your development environment includes:

• Rust (latest stable version)
• Cargo for Rust package management

Installation

Add CryptGuardLib to your Rust project by including it in your Cargo.toml file:

[dependencies]
crypt_guard = { git = "https://github.com/mm9942/CryptGuardLib.git" }

Usage

CryptGuardLib provides modules for key management (keychain), encryption (encrypt), and decryption (decrypt). Here's a basic usage example:

use crypt_guard::{encrypt, decrypt, keychain};

// Example: Encrypting and Decrypting a message
let keychain = keychain::Keychain::new().unwrap();
let encrypted_message = encrypt::Encrypt::encrypt_msg("Your message", keychain.shared_secret.as_ref().unwrap(), your_hmac_key)
    .await
    .expect("Encryption failed");
let decrypted_message = decrypt::Decrypt::decrypt_msg(&encrypted_message, keychain.shared_secret.as_ref().unwrap(), your_hmac_key, false)
    .await
    .expect("Decryption failed");

Features

• Keychain Management: Generate and manage cryptographic keys.
• Encryption: Encrypt data using state-of-the-art cryptographic algorithms.
• Decryption: Securely decrypt data back to its original form.

Testing

CryptGuardLib includes a suite of tests to ensure functionality. Run tests with:

cargo test

Dependencies

CryptGuardLib uses the following dependencies:

• aes: AES encryption.
• clap: Command-line argument parsing.
• pqcrypto-kyber: Post-quantum Kyber1024 algorithm.
• tokio: Asynchronous programming support.

Ensure these dependencies are included in your Cargo.toml when using CryptGuardLib.
