RGF

Option name: "rgf"
Option values: true/false/0-1/Function

Requires Eval

The obfuscated code will contain unsafe eval expressions. The code will not work properly in environments that have disabled eval.

Input / Output

This example showcases how RGF transforms the code. Try it out by changing the input code and see changes apply in real-time.

Input.js

// Input.js
function printToConsole(message) {
  console.log(message);
}

printToConsole('Hello World'); // "Hello World"

// Output.js
function ZQIWtZJ(ZQIWtZJ = !0) {
  return ZQIWtZJ;
}
var zQZeULs = ZQIWtZJ(),
  YqeQsOH = [
    mc2oyOd(
      'function gw49xP(){var[gw49xP,Syn9bRU]=arguments;function Eaw6eWv(gw49xP){console.log(gw49xP)}return Eaw6eWv.apply(this,Syn9bRU)}gw49xP;',
    ),
  ];
function F01ISEq() {
  return YqeQsOH[0].apply(this, [YqeQsOH, arguments]);
}
function mc2oyOd(ZQIWtZJ) {
  if (zQZeULs) {
    return eval(ZQIWtZJ);
  }
}
F01ISEq('Hello World');

Independent Functions

RGF will only transform functions that are independent of their scope. A function referencing a variable outside of its scope disqualifies it from being transformed. If you enable Flatten, you can isolate functions from their original scope so then RGF can then apply on them. This is the recommended way to use RGF.

Custom Implementation

`options.rgf(fnName)`

Control which functions are changed. Returns a boolean.

Parameter	Type	Description
`fnName`	`string`	The function name proposed to be changed.

Usage Example

The provided code example will obfuscate the file input.js and write the output to a file named output.js.

Usage Example

import JSConfuser from "js-confuser";
import {readFileSync, writeFileSync} from "fs";

// Read input code
const sourceCode = readFileSync("input.js", "utf8");
const options = {
  target: 'browser',
  rgf: true,
};

JSConfuser.obfuscate(sourceCode, options).then((result)=>{
  // Write output code
  writeFileSync("output.js", result.code);
}).catch(err=>{
  // Error occurred
  console.error(err);  
});
