JAVA动态混淆JS

相关项目依赖

主要流程

js代码调用javascript-obfuscator实现对指定文件的混淆

使用pkg将js打包成mac/linux/windows都可以执行的程序

在java中使用命令行进行js文件混淆

pkg打包

打包命令

npm install pkg -g

cd /打包目录 #目录中需要包含pkg配置文件

pkg ./JavaScriptObfuscator4File.js

可执行程序

在新的环境中运行前需要修改文件的权限，让它成为一个可执行的文件

chmod 755 ./file_name

使用打包程序进行js混淆

#使用绝对路径

./bin conf.file input.js output.js

混淆js的脚本

let JavaScriptObfuscator = require('javascript-obfuscator');

let fs = require('fs');

let path = require('path');

//入参

const argv = process.argv;

console.log('请指定待处理的文件地址');

return

}

const process_conf_file_path = argv[2];

const process_in_file_path = argv[3];

const process_out_file_path = argv[4];

let data = get_js_content();

let conf = get_obfuscate_conf();

let obfuscate_data = obfuscate(data, conf);

output_file(obfuscate_data);

console.log("混淆js成功");

function output_file(data) {

fs.writeFileSync(path.join(process_out_file_path), data);

}

function get_obfuscate_conf() {

return JSON.parse(data);

}

function get_js_content() {

let data = fs.readFileSync(path.join(process_in_file_path), "utf8");

return data;

}

function obfuscate(source_code, conf) {

let obfuscationResult = JavaScriptObfuscator.obfuscate(source_code, conf);

return obfuscationResult.getObfuscatedCode();
