.config文件加密解密

给配置文件加密，FrameWork2.0自带加密功能，只能对web.config加密，所以，如果是C/S项目，那么只要把app.config改成web.config即可。

打开SDK

-pef 加密

 <connectionStrings>    

	<add name="ConnectionString" connectionString="Data Source=.;Initial Catalog=HRMS20;Persist Security Info=True;User ID=sa;PassWord=sa" providerName="System.Data.SqlClient"/>  </connectionStrings>

</connectionStrings>

aspnet_regiis -pef  "节点名" "配置文件路径"

-pdf 解密

aspnet_regiis -pdf  "节点名" "配置文件路径"
