Code obfuscator CLI that protects your code regardless of the programming language or framework.

Package Exports

  • codefend
  • codefend/build/cjs/index.js
  • codefend/build/esm/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (codefend) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Codefend

GitHub Workflow Status NPM NPM NPM

Codefend short for "Code Defender" is a Code obfuscator CLI that protects your code regardless of the programming language or framework.
The complete list of examples for different programming languages/frameworks can be viewed here
Please make sure to read the Philosophy behind the obfuscation First to understand why Codefend can work with any code written in any language.

Installation

Globally

npm install -g codefend

Dev dependency

npm install -D codefend

npx

In case you want to execute it directly without installing it on your machine:

npx codefend -i  //required only the first time, generates .codefendrc.json
npx codefend -o  //obfuscates your whole project inside a new directory: 'codefend-output'

Commands

Usage: codefend [options]

Defend Your Code By All Means Necessary. 💪 😎

Options:
  -i, --init       Create the config file (.codefendrc.json)
  -o, --obfuscate  Obfuscate the project
  -c, --check      Check the config file for potential warnings/errors
  -v, --version    Output the version number
  -h, --help       Display help for command

Philosophy

  1. Codefend first copy all the files of your project to another directory by default: /codefend-output.
  2. Parse every word of every file of your project, searching for patterns in your code.
  3. Encrypts the detected words (Classes,Functions,Variables...) that matches the pattern.

The only thing Codefend needs from you as a programmer is to follow a specific naming convention for the words that you want to obfuscate (Classes,Functions,Variables...) and Codefend will do the rest ✨
This basic rule applies to all the languages and the frameworks that you will be programming with while using Codefend to defend your source.

Once your source code is obfuscated you can build the obfuscated version of your code and deploy it

Basic Usage

Step 1: Naming convention

Add prefixes to the words that you want to encrypt.

//as a starting point:  prefix the words that should be encrypted with l_
class l_Calculator {
  l_sum(l_a, l_b) {
    const l_results = l_a + l_b;
    return l_results;
  }
}

//>>>>>>==== Will Become ======<<<<<<

class Ox0 {
  Ox1(Ox2, Ox3) {
    const Ox4 = Ox2 + Ox3;
    return Ox4;
  }
}

// Or for a better organized naming convention:
/** 
 * 
1- class -> starts with c_
2- function -> starts with f_
3- parameter -> starts with p_
4- local variable -> starts with l_
*/
class c_Calculator {
  f_sum(p_a, p_b) {
    const l_results = p_a + p_b;
    return l_results;
  }
}

//>>>>>>==== Same results ======<<<<<<
class Ox0 {
  Ox1(Ox2, Ox3) {
    const Ox4 = Ox2 + Ox3;
    return Ox4;
  }
}

For Advanced usage, please check the Configuration section

Step 2: Run the CLI

navigate to the root of your project and run the following commands:

codefend -i  //required only the first time, generates .codefendrc.json
codefend -o  //obfuscates your whole project inside a new directory: 'codefend-output'

Step 3: install dependencies, build and deploy the obfuscated project

      /* navigate to the output folder*/
      cd codefend-output

      /* install the dependencies of the new obfuscated project */
      npm install

      /* run the obfuscated project */
      ...

      /* build the obfuscated project */
      ...

      /* deploy the obfuscated project */
      ...

Examples

  1. Node js

  2. Angular

  3. React

  4. Vue

  5. Svelte

  6. Python

  7. C#

  8. C++

Configuration

//default configuration generated inside .codefendrc.json
{
  debug: true,    // for additional logs
  generationOptions: {
    inputDir: ".", // the folder that should be copied and obfuscated ( keep it . if you're running in the same directory)
    outputDir: "codefend-output", // the output folder that will be an obfuscated clone of your code
    ignoredFilesInGeneration: [ // the files that should not be copied to the output folder
      "codefend-output",
      ".codefendrc.json",
      "node_modules",
      ".git",
      ".github",
      ".gitignore",
      ".vscode",
      "build",
      "dist",
      "README.md"
    ],
  },

  obfuscationOptions: {
    prefix: "Ox", // the prefix of each variable, make sure its a valid character to start with a variable ( e.g do not start with "-"" or a number)
    predefinedWords: [], // words that you want to obfuscate them in a static way (determined output)
                         // {"originalWord":"l_secretVar" , "targetWord": "123456"}
                         // note that the original word should have a prefix 'l_' to be detected and replaced

    ignoredWords: ["node_modules"], // words that you wish not to obfuscate them and they unfortunately match the regex :)
    regexList: [
      {
        name: "main",
        value: "([a-zA-Z]+(_[a-zA-Z0-9]+)+)",//regex for variables,functions,classes ...
        flag: "g",
      }
    ],
  },
}
