  • You can encrypt the connection string using the aspnet_regiis tool as described on MSDN here: http://msdn.microsoft.com/en-us/library/dtkwfdky(v=vs.80).aspx

    Also, here is an article describing how to encrypt the connection string programatically: http://www.beansoftware.com/ASP.NET-Tutorials/Encrypting-Connection-String.aspx

  • Hi,Thank you for reply my question.

    I am trying to develop for database secure  connection .

    My architecture is below.

    My dll has two method, one of them return connection object(Idbconneciton) and the other is sqldatasource object.

    My problem starts here. :(

     Some application using  sqldatasource control because of that I can't return connection object ( Idbconneciton). if I return sqldatasource object, it shows password    when I start debuging or messagebox ( sqldatasource.connectionstring), i don't want to do that.

    please help me.

  • Is it an option to use Windows integrated authentication for database access in your solution? Then you don't need to have the password in the connection string:


    If you are required to use SQL Server authentication, decrypt the connection string in your service DLL and then encrypt it on the client side.

  •  A lot of application are using my dll to connect to different database ( Sql server , oracle ,etc..) .

    Already i am doing  encrypt and decrypt in my dll ,but if developer is wonder connection string  .

    it can be see their applications.

    any application never see password if i return the connection object .

    Sqldatasource is not allowed secure connection and can be crack.

  • Hi erolc,

    Here is also a thread talking about how to hide password from connection string.


    However if you returns the connection object to clients, I'm afraid it is difficult to hide the information from properties.
