Lua脚本的加密压缩和解压缩

项目中lua脚本的热更新、将lua代码库打包成zip进行上传、下载 统一管理所有lua脚本的热更新。
项目中的配置文件也可以相同的办法处理
这里借助第三方压缩dll，ICSharpCode.SharpZipLib.dll

压缩部分

解压耗时 单位秒

用途：将一些零碎的文件集中打包管理更新
第一次写帖子，有点小激动，如果有不对的地方，还望指出
大神有更好的思路和方法 记得分享哦

下篇文章，和大家讨论下，lua中如何比较优的读取配置文件，网上大多数的方法，是将配置文件转换成LuaTable进行加载，这种方式读取起来比较费时，下篇文章讨论下用c语言读取配置文件解析到_G表中 集成到tolua.dll中
