加密SQL connectionstring c＃ [英] encrypt SQL connectionstring c#

问题描述

我创建了连接到sql 2005服务器的c＃应用程序（不是asp网页）。在我的源代码中，这个sql-server的密码和userid是ConnectionString中的纯文本。

I created an c# application (not asp webpage) which connects to a sql 2005 server. In my sourcecode the password and userid for this sql-server is coded plain text in ConnectionString.

SqlConnection con = new SqlConnection();
con.ConnectionString = 
         "Data Source=server1;"+
         "Initial Catalog=mydatabase;"+
         "Integrated Security=no;"+
         "User ID=admin;Password=mypassword;";
con.Open();

是否有一种简单的方法来加密密码或整个连接字符串，反汇编我的工具的其他人不是能够看到密码？

Is there a easy way to encrypt password or whole connectionstring, that other peoples who disassemble my tool are not able to see the password?

谢谢

推荐答案

你的连接字符串在一个配置文件并加密该部分。请参阅 http://www.4guysfromrolla.com/articles/021506-1.aspx或 http://msdn.microsoft.com/en -us / library / 89211k9b％28VS.80％29.aspx 。

You should store your connection string in a config file and encrypt that section. See http://www.4guysfromrolla.com/articles/021506-1.aspx or http://msdn.microsoft.com/en-us/library/89211k9b%28VS.80%29.aspx.
