代码混淆技术——Obfuscator

Obfuscator是一种用于混淆软件代码的技术,旨在保护程序免受反向工程攻击,同时不影响其执行性能。它通过删除人类可读的文本信息、压缩代码和删除未使用的元素来增加黑客破解的难度。虽然不会降低执行效率,但可以提高程序的加载速度和内存使用效率。对于源代码非公开、包含敏感信息或性能至关重要的Java和.NET程序,使用Obfuscator是必要的。

什么是Obfuscator ?

Obfuscator 只是迷惑了表面的分析者,而保持了机器编码层的一致性。软件 Obfuscator 使用混淆代码来挫败分析者的同时不破坏程序的执行。

    混乱代码以使客户机( JVM 和 CLR )并不明白内部的细节而能够正常使用。 Obfuscator 从编译后的代码中删除一些人或者反向工程软件可以读懂潜在的文字信息。它的目标就是从应用程序中去除上下文联系的同时保持程序的完整性。通过大量的技巧和坚持不懈的努力,黑客仍然可以反编译出代码的真正含义。 Obfuscator 的目标是提高黑客破解的难度,使得反向工程非常困难,以至于黑客不值得为破解做出那么大的努力。

淘宝花钱买的最新版!需要的拿去! This asset obfuscates your code to make it harder for bad guys to reverse engineer your projects. Specifically designed for Unity, it seamlessly links in with its build process. The top priority of this package is to work straight out of the box with no extra steps required. While other obfuscators can stop a game from working, Beebyte's obfuscator looks for specific Unity related code that must be protected. The contents of your source files are unchanged, the obfuscation targets the compiled assembly. Features: - Supports IL2CPP - Supports Assembly Definition Files (Unity 2017.3+) - Removes Namespaces without any conflicts - Recognises Unity related code that must not be changed - Renames Classes (including MonoBehaviours) - Renames Methods - Renames Parameters - Renames Fields - Renames Properties - Renames Events - String literal obfuscation - Adds fake methods - Easy and extensive customisation using the Unity inspector window - Consistent name translations are possible across multiple builds and developers - Semantically secure cryptographic naming convention for renamed members The asset works for both Unity Free and Unity Pro version 4.2.0 onwards (including Unity 5 & 2017 & 2018). Build targets include Standalone, Android, iOS, WebGL, UWP. Other platforms are not guaranteed or supported but may become supported at a future date. IL2CPP builds are much harder to reverse engineer but strings and member information (class, method names etc) are visible in the global-metadata.dat file. Obfuscation will apply to this file adding further security. Why not complement your security with the Anti-Cheat Toolkit - a great third party asset.

### Unity 中实现代码混淆的方法 为了提升开发的游戏或应用程序安全性,Unity Obfuscator Pro 5.10 提供了一种有效的手段来对抗逆向工程,保障开发者的核心逻辑不易被破解和复制[^1]。 #### 安装与配置 安装此插件前需确认已拥有适当版本的 Unity 编辑器环境。对于希望利用最新特性并享受稳定性的用户而言,建议访问官方提供的项目页面以获取最新的发布包以及详细的集成指南[^2]。通常情况下,在 Asset Store 或指定链接处可以找到对应的资源文件用于导入至目标项目中[^3]。 #### 使用说明 完成上述准备工作之后,便可以在 Unity Editor 内部操作界面里发现新增加的功能选项卡——“Obfuscator”。这里提供了直观易懂的操作面板让用户能够轻松设置想要应用混淆处理的具体范围及其强度参数: - **选择待保护的目标**:一般指代编译后的程序集(即 .NET DLL 文件),例如 `Assembly-CSharp.dll` 这样的默认脚本集合。 - **定义混淆策略**:包括但不限于重命名变量名、移除无用元数据、控制流转换等措施,这些都会增加反汇编难度进而达到预期效果[^4]。 ```csharp // 示例:简单的 C# 方法可能会变成如下形式 public class MyClass { public void MyMethod() { ... } } ``` 经过混淆后可能变为: ```csharp public class a { public void b() { ... } } ``` 这种变化使得外部人员难以理解原始意图的同时又不影响正常运行时的行为表现。
