CryptGuard: Kyber Programming Library

Crates.io MIT licensed Documentation GitHub Library GitHub CLI

Introduction

CryptGuard: Kyber is a comprehensive cryptographic library, offering robust encryption and decryption capabilities. It integrates traditional cryptography with post-quantum algorithms, ensuring resilience against quantum computing threats. Designed for developers, CryptGuard: Kyber empowers applications to withstand future digital security challenges. Embrace CryptGuard: Kyber as your trusted ally in safeguarding privacy in the digital realm.

Prerequisites

Ensure your system has the latest stable versions of Rust, Cargo, and the Tokio runtime environment.

Encrypting Data

Encrypt data using encrypt, encrypt_msg, or encrypt_file functions from the Encrypt struct.

Encrypt a Message

use crypt_guard::{
    File,
    Encrypt,
    Decrypt,
    Keychain,
    FileRemover,
    Signing,
    Sign,
    ActionType,
};

#[tokio::main]
async fn main() {
    let encrypt = Encrypt::new();
    let keychain = Keychain::new().unwrap();
    let message = "This is a secret message!";
    let hmac_key = b"encryption_test_key";

    let encrypted_message = encrypt.encrypt_msg(message, keychain.shared_secret.as_ref().unwrap(), hmac_key)
        .await
        .expect("Failed to encrypt message");
}

Encrypt a File


#[tokio::main]
async fn main() {
    let encrypt = Encrypt::new();
    let keychain = Keychain::new().unwrap();
    let file_path = PathBuf::from("path/to/your/file.txt");
    let hmac_key = b"encryption_test_key";

    let _ = encrypt.encrypt_file(file_path, keychain.shared_secret.as_ref().unwrap(), hmac_key)
        .await
        .expect("Failed to encrypt file");
}

Decrypting Data

Decrypt data using decrypt, decrypt_msg, or decrypt_file functions from the Decrypt struct.


#[tokio::main]
async fn main() {
    let decrypt = Decrypt::new();
    let keychain = Keychain::new().unwrap();
    let encrypted_data = ...; // Load your encrypted data here
    let hmac_key = b"encryption_test_key";

    let decrypted_message = decrypt.decrypt_msg(encrypted_data, keychain.shared_secret.as_ref().unwrap(), hmac_key)
        .await
        .expect("Failed to decrypt message");

    let file_path = PathBuf::from("path/to/your/encrypted_file.txt");
    let _ = decrypt.decrypt_file(file_path, keychain.shared_secret.as_ref().unwrap(), hmac_key)
        .await
        .expect("Failed to decrypt file");
}

Keychain Usage

The Keychain struct in CryptGuard: Kyber facilitates key management. It supports loading and saving public keys, secret keys, shared secrets, and ciphertexts.


fn main() {
    let keychain = Keychain::new().unwrap();
    // Load or generate keys as required
}

New Feature: xchacha20

The xchacha20 feature in CryptGuard: Kyber introduces the XChaCha20 encryption algorithm, providing an additional layer of security for your cryptographic needs. This feature is optional and can be enabled in your Cargo.toml.

Encrypting Data with XChaCha20

#[cfg(feature = "xchacha20")]

#[tokio::main]
async fn main() {
    #[cfg(feature = "xchacha20")]
    {
        let encrypt = Encrypt::new();
        let keychain = Keychain::new().unwrap();
        let message = "This is a secret message!";
        let nonce = generate_nonce();
        let hmac_key = b"encryption_test_key";

        let encrypted_message = encrypt.encrypt_msg_xchacha20(message, keychain.shared_secret.as_ref().unwrap(), &nonce, hmac_key)
            .await
            .expect("Failed to encrypt message with XChaCha20");
    }
}

Decrypting Data with XChaCha20

#[cfg(feature = "xchacha20")]

;

#[tokio::main]
async fn main() {
    #[cfg(feature = "xchacha20")]
    {
        let decrypt = Decrypt::new();
        let keychain = Keychain::new().unwrap();
        let nonce = ...; // Load your nonce here
        let hmac_key = b"encryption_test_key";
        let encrypted_data = ...; // Load your encrypted data here

        let decrypted_message = decrypt.decrypt_msg_xchacha20(encrypted_data, keychain.shared_secret.as_ref().unwrap(), &nonce, hmac_key, false)
            .await
            .expect("Failed to decrypt message with XChaCha20");
    }
}
