Codefend
is a dynamic 🪩 CLI tool that obfuscates your source code, folders, and file names, compatible with any programming language or framework.
It delivers powerful obfuscation while ensuring performance maintained âš¡, so you benefit from enhanced security without compromising your application's speed or efficiency.
Additionally, Codefend offers plugins for Webpack, Rollup, and Vite.
Beyond simple obfuscation, Codefend delivers advanced features, integrating smoothly with current uglifiers or minifiers. It employs a two-layer obfuscation 🪞 process, embedding hidden code within hidden code for irreversible source code protection.
For Codefend to work properly, you need to implement a folder and files naming convention, a code naming convention, or both. Once set up, Codefend will handle obfuscation, allowing you to concentrate on development and safeguard your intellectual property ✨
Visit the docs for instructions, examples, and advanced settings.
Globally
npm install -g codefend
codefend -i //required only the first time, generates .codefendrc.json
codefend -o //obfuscates your whole project inside a new directory: 'codefend-output'
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'
Webpack
If you're using Webpack, you can use webpack-plugin-codefend instead of directly using the CLI, keeping in mind that not all features are propagated to the plugin and may take time to become available.
Rollup/Vite
If you're using Rollup or Vite, you can use rollup-plugin-codefend instead of directly using the CLI, keeping in mind that not all features are propagated to the plugin and may take time to become available.
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
Step 1
: Naming conventionAdd 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;
}
}
<!-- Html example, can work also with Angular,React,Vue,Svelte... in the same way -->
<html>
<head>
<style>
.l_red {
color: red;
}
</style>
</head>
<body>
<div class="l_red">l_secret</div>
<div class="l_red">Hello World</div>
</body>
</html>
<!-- Will Become -->
<html>
<head>
<style>
.Ox1 {
color: red;
}
</style>
</head>
<body>
<div class="Ox1">Ox0</div>
<div class="Ox1">Hello World</div>
</body>
</html>
Step 2
: Run the CLInavigate 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'
For a more detailed explanation, please refer to the obfuscation section of the docs.
Step 3
: install dependencies, build and deploy the obfuscated projectPlease refer to the build and deployment and troubleshooting sections of the docs.
Please refer to the configuration section of the docs.
Please refer to the migration guide section of the docs.
