ncrypt_me - Secure Data Encryption

How the Data is Encrypted

Given some Credentials (username and password):

• Hashing: Both the password and username are hashed using Argon2.

  • The resulting hash of the password is used as the key for the XChaCha20Poly1305 cipher.
  • The resulting hash of the username is used as the Additional Authenticated Data (AAD) for the cipher.

• Encryption: With the key and AAD set, the data is encrypted using the XChaCha20Poly1305 cipher.

• Output: The encrypted data is then returned.

Example

use ncrypt_me::{encrypt_data, decrypt_data, Credentials, Argon2, secure_types::{SecureString, SecureBytes}};

let exposed_data: Vec<u8> = vec![1, 2, 3, 4];
let credentials = Credentials::new(
 SecureString::from("username"),
 SecureString::from("password"),
 SecureString::from("password"),
);

// I don't recommend using such low values, this is just an example

let m_cost = 24_000;
let t_cost = 3;
let p_cost = 4;

let argon2 = Argon2::new(m_cost, t_cost, p_cost);
let secure_data = SecureBytes::from_vec(exposed_data.clone()).unwrap();
let encrypted_data = encrypt_data(argon2, secure_data, credentials.clone()).unwrap();

let decrypted_data = decrypt_data(encrypted_data, credentials).unwrap();

decrypted_data.unlock_slice(|decrypted_slice| {
 assert_eq!(&exposed_data, decrypted_slice);
});
