json-ed-aes

json-ed-aes-gcm is a simple aes-256-gsm encrypt and decrypt module for node.js. This module is build for both Commonjs and ECMAScript.

It is for doing encryption of json object or string using aes-256-gcm with a provided secret and then decrypt the encrypted message with the secret.

The encrypted message is a combination of encrypted message, iv, tag and salt.

The JsonEncryptDecryptAES constructor takes one required argument secret.

The salt and iv are randomly generated and prepended to the result and secret is the key by which the message is decrypted.

This Module is not for password generation.

Passwords are one way hash and there are many library you can choose form.

Install

npm install @faizul-mustafiz/json-ed-aes

Usages

Basic Example

Node.js Module

const JsonEncryptDecryptAES =  require('@faizul-mustafiz/json-ed-aes');
const aes = new JsonEncryptDecryptAES.default('my-super-secret');

// Encrypt an json object
const encryptMessage = aes.encrypt({  deviceId: '67256558250eda49',});

// Decrypt an encrypted message
const decryptMessage = aes.decrypt(encryptMessage);

console.log('encryptMessage:', encryptMessage);
// encryptMessage: HxMsz/kBD5vKP5IJvgrotFHHDfcOy0YYgZ6ukaGpTDpoJi93PXERAu8ii9m0KJWxm3AWaJnaJTD5e5Ca8wl/MDQL1vgq1Na1M3jBKu3ZMHHpoIT7krzC4pURw3pRgd9j8tQ3NSrwWzzhrIdm03bjmtfR2MgyyNBIj5saQKuMhA==

console.log('decryptMessage:', decryptMessage);
// decryptMessage: { deviceId: '67256558250eda49' }
