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 for each obfuscated variable
prefix: "Ox",
// control how a specific variable should be obfuscated
static: [
{
from: "predefined_secret",
to: "123456",
},
],
//will skip obfuscation for the following words
ignore: ["node_modules"],
// By using everyday words such as books or recipes in the pool, you can subtly obfuscate your code, concealing its true nature without making it apparent that obfuscation is occurring.
pool: ["QueenOfHeart"],
},
debug: {
// to display 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_secret");
return l_results;
}
}
//>>>>>>==== Will Become ======<<<<<<
class QueenOfHeart /* 'QueenOfHeart' defined in pool*/ {
/* Ox1, Ox2... prefix transformation*/
Ox1(Ox2, Ox3) {
const Ox4 = Ox2 + Ox3;
console.log("node_modules"); // has not been obfuscated
console.log("123456"); // has transformed from "predefined_secret" to "123456"
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>
