Description

@despair56434/encryption is a Node.js module that provides utility functions for encryption and decryption using the AES-256-GCM algorithm. It includes functions to generate cryptographic keys and initialization vectors (IVs), as well as to encrypt and decrypt data.

Installation

To install this package, use npm:

npm install @despair56434/encryption

Usage

Importing the Module

import {
  decryptData,
  encryptData,
  generateIV,
  generateKey,
} from "@despair56434/encryption";

Generating a Key

const password = "password";
const salt = "salt";
const iterations = 1000; // random number you will implement in your application
const key = generateKey(password, salt, iterations);

Generating an Initialization Vector (IV)

const IV = generateIV();

Encrypting Data

const data = {
  name: "username",
  surname: "surname",
  age: 24,
  email: "[email protected]",
};
const encryptedData = encryptData(key, IV, JSON.stringify(data));

Decrypting Data

const decryptedData = decryptData(key, encryptedData);

Changelog

1.0.4

• Improved Error Handling
• Improved types

1.0.3

• Updated encryptData and decryptData functions to handle the authentication tag properly.
• Ensured that the IV and auth tag are prepended to the encrypted data and correctly extracted during decryption.
