Lua代码加密，防止代码反编译
加密目的：
在游戏开发中，脚本作为一种资源文件，就像图片视频一样，被引擎所引用。如果不对脚本进行加密，不怀好意的人轻松解压出脚本文件，给你瞬间复制一个游戏出来。在程序发布前一般会对脚本进行加密，防止代码泄漏。
加密工具：
Virbox Protector
DS Protector
优点：
便捷，一键加壳，无需编写代码。
安全，混淆、虚拟化、碎片代码、反黑、定制SDK等最新加密安全技术。
快速，5分钟完成整个程序加壳，专注软件开发。
灵活，云锁、软锁、硬件锁三种许可形式，可满足联网或离线场景，云和软无需硬件加密。
加密工具下载：
SDK需Virbox LM帐号，获取许可ID及密码
1、 获取SDK：https://developer.lm.virbox.com/reg.html?code=f260815126
注册后，转正即可下载定制SDK
2、文档下载： https://lm.virbox.com/fangan.html
包含加密快速流程及加壳详细文档
加密流程
1、注册帐号
2、安装SDK
3、用Virbox Protector对安装目录下的lua.exe 进行加壳。如何加壳？
4、打开 DS Protector，导入刚加壳生成的配置工具，添加所需要保护的demo ，点击保护
5、进入 demo 所在的目录下，运行如lua demo.lua
