ObjectRSA

Encrypt and decrypt JavaScript objects using asymmetric key encryption

Installation

npm install object-rsa

Usage

Initialize the class with at least a key. Have this in mind:

• Private keys can encrypt and decrypt
• Public keys can only encrypt

import ObjectRSA from 'object-rsa';

const objectRsa = new ObjectRSA({
  privateKey: '------',
  publicKey: '------'
});

You can create a key pair with the crypto module:

import crypto from 'crypto';

const { publicKey, privateKey } = crypto.generateKeyPairSync('rsa', {
  modulusLength: 2048,
});

Methods

Encrypt object

const objectToEncrypt = {
  number: '4242 4242 4242 4242',
  code: '939',
  expiration: '12/23'
};

const encryptedObject = objectRsa.encrypt(objectToEncrypt);

encryptedObject will now look like:

{
  number: 'bo3gQCqp96Ksqt47BuVGGj+jpjK4Q5j8mAmv+EgW...',
  code: 'DF/pkpCbgRJ61z1pHhH2sps02pN0S2eFY9XI6QFzvmMvN...',
  expiration: 'FaAYCvvMvciMcY1AGX2Jaoy2sf5pzaP...'
}

Decrypt object

const objectToDecrypt = {
  number: 'bo3gQCqp96Ksqt47BuVGGj+jpjK4Q5j8mAmv+EgW...',
  code: 'DF/pkpCbgRJ61z1pHhH2sps02pN0S2eFY9XI6QFzvmMvN...',
  expiration: 'FaAYCvvMvciMcY1AGX2Jaoy2sf5pzaP...'
};

const decryptedObject = objectRsa.decrypt(objectToDecrypt);

decryptedObject will now look like:

{
  number: '4242 4242 4242 4242',
  code: '939',
  expiration: '12/23'
}

What is encrypted

For now, not every value inside the object is encrypted. Check this list (✅ is encrypted, ❌ is not encrypted):

• Strings ✅
• Objects ✅
• Arrays ✅
• Arrays of objects ✅
• Booleans ❌
• Numbers ❌
