解密ASP源代码

从网上兴致冲冲地下载了ASP源代码,准备学习研究的时候.一打开文件,天书般的加密代码.很让人郁闷吧:(在网上是找到了解密的方法,得一个文件挨一个文件地打开,复制,粘贴,解密,再复制,再粘贴,再保存……如果一个ASP程序有几百个文件??? 解决办法来了..复制代码代码如下:<%@Language=\”JavaScript\”%> <% /* *—————decode.asp—————– *功能:遍历某个目录下的所有文件,对加密过的.asp文件 *进行解密,并写入源文件中. *实例:单个文件解密 *Response.Write(DncodeFile(Server.MapPath(\”conn.asp\”)));
