A javaScript Obfuscation middleware library for expressjs built on top of javascript-obfuscation
npm install confusionjsConfusionjS is a javascript obfuscation middleware library for nodejs.
In order to use confusionjs into your nodejs express app, install the module into project like so:
Install using npm:
``shell`
$ npm install --save confusionjs
Install using Yarn:
`shell`
$ yarn add confusionjs
In Node.js Express App:
`js
// Load express
const express = require("express");
// Load Confusionjs
const confuse = require('confusionjs');
const app = express();
let options = {
root:"./static",
store:"confused"
cache:true,
debug:true,
};
app.use(confuse(options));
`
Note:
Install ConfusionJs for use in the Node.js > 8
JavaScript code running in the browser is visible to anybody who wishes to see it. This can sometimes pause a security threat to your application as people with malicious intent can steal or compromise your source code.
ConfusionJs limits those threats by obfuscating the javascript code so that it becomes difficult to read or decipher.
consider the following script as example:
`js
(function(){
alert("confuse the enemy!");
})();
`
In a normal setup, the code will just be delivered as is and anybody will be able to see the code.
However, Confusionjs takes the raw code and obfuscates it into a more hard to read and decipher syntax such as the one below:
`js
var _0x4f62 = [
'FhxUT',
'btlxw'
];
(function (_0x30ac87, _0x346513) {
var _0x2f9996 = function (_0x360049) {
while (--_0x360049) {
_0x30ac87'push');
}
};
_0x2f9996(++_0x346513);
}(_0x4f62, 0x18f));
var _0x11b1 = function (_0x11e762, _0x3fac47) {
_0x11e762 = _0x11e762 - 0x0;
var _0x58af7a = _0x4f62[_0x11e762];
return _0x58af7a;
};
(function () {
var _0x178c8d = {
'btlxw': function (_0x110a9e, _0x35231c) {
return _0x110a9e(_0x35231c);
},
'FhxUT': 'hit'
};
_0x178c8d_0x11b1('0x0')]);
}());
``
* root : A string. this represents the root of your static or public folder e.g "./static" or "./public"
* store: A string. a folder where to store the obfuscated javascript files
* cache: A boolean. determines wether or not confusionjs should create a new confused file everytime a js file is requested
* debug: A boolean. wether to log to console any debug information e.g when a file is cahed or served from cache
