NodeJS Encryption Sample Code

Overview

This project demonstrates encryption and decryption using RSA and AES algorithms in Node.js. It includes two main scripts:

1. generateTestData.js: Generates RSA key pairs, encrypts data using AES, and encrypts the AES session key using RSA.
2. decrypt.js: Decrypts the AES session key using RSA and then decrypts the data using the decrypted AES session key.

Steps and Functionality

1. Generating Test Data (generateTestData.js)

This script performs the following steps:

• Generates an RSA key pair (public and private keys).
• Saves the private key to a file (private-key.pem).
• Saves the public key to a file (public-key.pem).
• Generates a random AES session key.
• Encrypts a sample data string (encryptme!) using AES with the generated session key and a random IV (Initialization Vector).
• Encrypts the AES session key using the RSA public key.
• Outputs the encrypted session key, encrypted data, and IV in Base64 format.

Example Usage

node generateTestData.js
