JObfuscator 是一款针对 Java 编程语言的源代码混淆器。它可以保护您的 Java 源代码和算法，防止黑客攻击、破解、逆向工程、反编译和技术盗窃。

JObfuscator 采用多种混淆技术来保护并隐藏您的 Java 源代码的真实功能。

它重命名所有变量和方法，通过使代码流程非线性来混淆代码流，并使用我们尖端的多态 字符串加密 引擎加密所有字符串。

Java 反编译是一个大问题

用 Java 编写并编译为 JAR、WAR 或 CLASS 格式的应用程序容易受到反编译的影响。

存在许多 反编译器，几乎可以将编译后的代码完全重新创建回 Java 源代码。

问题在于编译后的 Java 代码是针对 JVM（与类似 x86 或 x86-64 的本地 CPU 代码相反）的所谓 字节码。

除了被完美地 记录 外，这种代码形式允许在高级 Java 源代码中非常精确地复制原始指令。

Java 反编译器能做什么？

看看这个例子

Java JAD Decompiler

这是 反编译 的 Java 代码！所有变量、属性和方法名称都是可读的。您甚至可以轻松地浏览整个反编译项目，从一个类跳转到另一个类。

您感到惊讶吗？这可能是您的软件被竞争对手、黑客、破解者或其他人分析的情况。

技术与知识产权（IP）盗窃

他们能做什么？大多数情况下，软件或其算法被窃取或复制到竞争产品中。

在其他一些情况下，软件被破解，在反编译的源代码中可以清楚地看到许可证检查被修补，甚至整个破解软件被重新编译并发布在盗版网站上。

Java 源代码混淆

混淆是将 Java 源代码转换为自身 受保护 版本的过程。

功能保持 不变，一切正常工作，但源代码和最终编译的字节码受到保护，即使在反编译后也免受逆向工程分析。

混淆前的示例 Java 源代码

//

    {
        double sum = 0.0, standardDeviation = 0.0;
        int length = numArray.length;

        for(double num : numArray) {
            sum += num;
        }

        double mean = sum/length;

        for(double num: numArray) {
            standardDeviation += Math.pow(num - mean, 2);
        }

        return Math.sqrt(standardDeviation/length);
    }

    //

如果您不知道原始源代码，您能说出混淆代码做什么吗？

保护您的 Java 项目和算法

不要冒险，使用 JObfuscator 混淆和保护您的 Java 项目和算法。

我们公司在混淆技术和代码混淆器方面拥有悠久的历史（请参阅我们的 x86 汇编 & AutoIt 混淆器）。

我们积极修复错误、研究和开发新的混淆策略，以应用于我们的工具。

您可以依赖我们在该领域的专业知识和支持。

安装

WebApi 接口的推荐安装方式是通过 composer。

运行

php composer.phar require --prefer-dist pelock/jobfuscator "*"

或者将此条目

"pelock/jobfuscator": "*"

直接添加到您的 composer.json 的 require 部分。

安装包可在 https://packagist.org.cn/packages/pelock/jobfuscator 获取
