Introducing node.data.obfuscator

• Download source code from Github

Background

Well, I have built an app with React Native and had to have some sensitive data for Firebase and others.

The solution could be to include that data in a native side, but doing this will result in having to build a native module for IOS, Android and Windows. I wanted to skip that and an idea come to me.

When you build a React Native app, it will create a JS bundle. What if the data is shuffled and unreadable so even if someone looks at it, he wouldn't understand any of it anyway? And this is how I came up with this idea to hide the data in JS files.

Platforms

This library will work with any platforms React, React Native and web.

Installation

npm i -D node.data.obfuscator 

OR:

npm i node.data.obfuscator -g

Using the Code

For help, simply execute cla help secure.

Let's say we have secure.json that contains the following JSON:

{
  "user": "test",
  "password": "test.password"
}

To obfuscate a file, simple execute cla secure -f "../secure.json" -p "./data" -c 3

The library will know if the file content is a JSON or simple string and return it as it should be. The command above will create a folder with name 'data' that will contain the following files:

To make it create less files, simply remove or increase --counter.

As for the content or the files, it will be the following. For the preview below, I removed --counter so it creates two files for the preview:

// x0.js
// the array below is impossible to read as it is shuffled.
const x0= ['\u0074','\u003a','\u0022','\u000a','\u007b','\u0070',
           '\u0077','\u0073','\u002c','\u0064','\u0072','\u0065','\u002e',
           '\u006f','\u0061','\u007d','\u0020','\u000d','\u0075'];
export default [x0, ""];

// index.js
import x0 from './x0'
let x36=x0[0X1];
x36+=x0[0X0][0X4];
x36+=x0[0X0][0X11];
x36+=x0[0X0][0X3];
x36+=x0[0X0][0X10];
x36+=x0[0X0][0X10];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X12];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0XB];
x36+=x0[0X0][0XA];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X1];
x36+=x0[0X0][0X10];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X0];
x36+=x0[0X0][0XB];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0X0];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X8];
x36+=x0[0X0][0X11];
x36+=x0[0X0][0X3];
x36+=x0[0X0][0X10];
x36+=x0[0X0][0X10];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X5];
x36+=x0[0X0][0XE];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0X6];
x36+=x0[0X0][0XD];
x36+=x0[0X0][0XA];
x36+=x0[0X0][0X9];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X1];
x36+=x0[0X0][0X10];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X0];
x36+=x0[0X0][0XB];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0X0];
x36+=x0[0X0][0XC];
x36+=x0[0X0][0X5];
x36+=x0[0X0][0XE];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0X7];
x36+=x0[0X0][0X6];
x36+=x0[0X0][0XD];
x36+=x0[0X0][0XA];
x36+=x0[0X0][0X9];
x36+=x0[0X0][0X2];
x36+=x0[0X0][0X11];
x36+=x0[0X0][0X3];
x36+=x0[0X0][0XF];
export default JSON.parse(x36)

Now for use, you can simply do the following;

import secureJSON from './data'
console.log(secureJSON.password);

Points of Interest

This is a simple library that will make your data available in JS and secured.
