AES-256-CBC Cryptography Module

This Node.js module provides a simple and secure way to encrypt and decrypt data using the AES-256-CBC algorithm. It's designed to help developers implement robust encryption in their applications with minimal setup.

Features

• Secure Encryption: Utilizes the strong AES-256-CBC encryption algorithm.
• Easy Integration: Simple API for encrypting and decrypting data.
• Environment Variable Support: Uses environment variables to manage encryption keys securely.

Getting Started

Prerequisites

You'll need Node.js installed on your machine. This project is tested with Node.js version 14.17.0 or higher. You can download Node.js here.

Installation

Clone the repository and install its dependencies:

git clone https://github.com/sachintalekar07/AES_256_CBC_CRYTO.git
cd AES_256_CBC_CRYTO
npm install

Usage

Here is a quick example of how to use this module:

const { encrypt, decrypt } = require('./path_to_module');

const data = { name: 'John Doe', age: 30 };
const key = process.env.PROJECT_ENCRYPTION_KEY;  // Ensure your key is set in the environment variables

const encrypted = encrypt(data, key);
console.log('Encrypted:', encrypted);

const decrypted = decrypt(encrypted.IV, encrypted.encryptedData, key);
console.log('Decrypted:', decrypted);

Environment Variables

Make sure to set the following environment variables in your .env file:

PROJECT_ENCRYPTION_KEY=your_secure_key_here

API Reference
