问题描述

我要在连接字符串中的密码进行加密。当我做一个连接到DB连接字符串是公开存储在App.config中，我需要找到一种方法，只保留密码加密。

I want to encrypt the password in connection string. When I make a connection to DB the connection string is openly stored in App.config and I need to find a way to keep only password encrypted.

推荐答案

可以说，这是你的连接字符串：

Lets say this is your connection string:

<connectionStrings>
    <add name="cs" connectionString="Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=XXSDFASFDKSFJDKLJFDWERIODFSDFHSDJHKJNFJKSD;"/>
</connectionStrings>

然后，你可以做这样的事情：

Then you can do something like this:

string myCs = System.Configuration.ConfigurationManager.ConnectionStrings["cs"].ConnectionString;

System.Data.SqlClient.SqlConnectionStringBuilder csb = new System.Data.SqlClient.SqlConnectionStringBuilder(myCs);
csb.Password = EncDecHelper.Decrypt(csb.Password);
myCs = csb.ToString();

您可以写 EncDecHelper.Decrypt 用样品从这里：的的加密/解密字符串在.NET
