Rollup plugin for code obfuscation based on Codefend
npm install -D rollup-plugin-codefend
Step 1: ConfigurationAdd to your rollup.config.js:
import { codefend } from "rollup-plugin-codefend";
export default {
input:...,
output: ...,
plugins: [codefend()],
};
import { codefend } from "rollup-plugin-codefend";
export default {
input: ...,
output: ...,
plugins: [
codefend({
transformation:{
// the prefix to use of each obfuscated variable
prefix: "Ox",
// control how a specific variable should be obfuscated
static: [
{
from: "predefined_secretword",
to: "123456",
},
],
//will skip obfuscation for the following words
ignore: ["node_modules"],
},
debug: {
// to dislpay detailed stats about the words that have been obfuscated
stats: true,
},
}),
],
};
For a more detailed explanation, refer to the configuration section of the codefend docs.
Step 2: Naming conventionIn your code, add prefixes to the words that you want Codefend to encrypt.
Make sure to read the Philosophy behind Codefend obfuscation First to understand why Codefend can work with any code written in any language.
//node js example
//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;
console.log("node_modules");
console.log("predefined_secretword");
return l_results;
}
}
//>>>>>>==== Will Become ======<<<<<<
class Ox0 {
Ox1(Ox2, Ox3) {
const Ox4 = Ox2 + Ox3;
console.log("node_modules"); // will not be obfuscated as it is added to ignore
console.log("123456"); // will be transformed from predefined_secretword to 1234567 as it was added to staticoptions
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 -->

<style>
.Ox1 {
color: red;
}
</style>
</head>

<div class="Ox1">Ox0</div>
