Configuration :: Encrypting Only ConnectionString?
Aug 24, 2010
i'm working on already built asp.net webapplication. in the web.config for connectionString section i have seen this
<add name="MyConnectionString" connectionString="3abcde12n3kd03kldwqaswe45tdw4fo23003ld3ddfot0lkdpe2d" providerName="System.Data.SqlClient"/>
can anyone tell me on how this encryption done? i know the standard way of encrypting using aspnetregiis.exe which replaces the entire connnectionString section of the web.config.

I am getting the error "An error occurred loading a configuration file: Access to the path is denied."
When I am in VS 2010, I can Encrypt as long as I run as administrator. Code as follows:
[Code]....
My problem is I need to run this in IIS. What is stopping me? It's a permission problem, but what permission. I am running IIS 7.5 on Windows 7. This is happening on my production server as well. Same error.

I have a custom section in a web application that I am having trouble encrypting. I have written an external .NET program that will encrypt both .NET 1.1 & .NET 2.0 web/app configs.Up until this point in time, I have never had to encrypt any custom sections for either type of application. Anyway, the way I set it up for my web application is I wrote a class library that I import into the web application which allows me to set up and read from the custom section in the web.config. That all works fine... I added the custom section, and the web pages are able to read the values fine.

I have been reading up on encrypting the connectionStrings section of the web.config file and I have noticed that all of the methods embed the cypher key in either the registry or the machine.config file. My site is currently being hosted for me by a hosting company and as such I do not have direct access to the registry (or aspnet_regiis for that matter). I was wondering what options are available to me if I cannot use the usual aspnet_regiis method or am I misreading the posts?

I just deployed my database to my remote server. I am trying to create a connectionstring to the remote server and it won't work. I am using godaddy. I kept having this message: could not establish a connection to the database. Here is the connectionstring for the local server:
<connectionStrings>
<add name="ApplicationServices" connectionString="data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"

How do I use aspnet_regiis to encrypt <connectionStrings> on a website that is hosted remotely? I guessing I need to use a machine-level container? I was able to do it locally with a user level container using this command:
aspnet_regiis -pef "connectionStrings" C:mysite -prov "DataProtectionConfigurationProvider"
but now I need to encrypt parts of the web.config in my real site hosted remotely and don't know how to do it I've created a custom RSA key and exported it to an xml file (is that the right way to do it?) but how do I use it in the web.config file?

I'm creating a multi-tenant Asp.Net MVC 3 Web app, and using EF4.1 code first for the db model.For development I'm happy to use SqlServerCE in App_Data, and for production this will move to Sql Server 2008.
Say my context is called "MyModels", by default code-first looks for a connection string called "MyModels" in Web.config. This can be told to use a file in App_Data or changed to access a database in SQL2008. All fine so far.
But because of multi-tenancy, I'd like the SqlServerCE filename to match the unique id of the tenant (so App_Data would have "client_x.sdf", "client_y.sdf"; Sql Server 2008 would have separate databases). I can't work out how to direct to these different databases.
I've tried MyModels inheriting from DbContext and supplying a connection string (using a 'placeholder' conn string in Web.config and replacing "{clientId}" with the unique id), and I've also tried setting the connection string in the MyModels constructor:
base.Database.Connection.ConnectionString = xxx;
but this never seems to work. I always get the following error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
( it's not yet 'configured' to use SqlServerCE, and so is trying to connect to Sql Server)
Tracing the code, Database.Connection.ConnectionString hasn't been read from Web.config at this point, so I can't search and replace that, and, possibly, it's getting overwritten by the 'placeholder' conn string later in the pipeline.I reckon this must be quite straightforward and I just can't find the 'hook'.

When I try to encrypt the "connectionStrings" section in the web.config file of my asp.net web application on Windows Server 2008, I'm getting the following error:
Administration utility (2.0.50727) to install and uninstall ASP.NET on the local machine. Copyright (c) Microsoft Corporation. All rights reserved. Note: This utility has limited capabilities on the Windows Vista operating system. It is recommended that you use the "Turn on or off Windows features" option of the "Programs" component of Control Panel to install or remove ASP.NET. It is also recommended that you use the IIS Manager component or the Appcmd.exe tool to configure ASP.NET applications.
The above information is followed by the list of valid options to aspnet_regiis.exe.
The command that I've used is:
aspnet_regiis.exe -pef "connectionStrings" "C:Usersuser1DocumentsMywebsite" -prov "DataProtectionConfigurationProvider"
But, the same command is working fine when used on a Windows Server 2003 machine. The problem is occurring only on Windows Server 2008 with IIS7.

found while searching for help on my asp.net application.I have a small application with connected to a SQL database. As it was so small, and contained very little data of any importance, i had set it up with Clear passwords.Now i have been asked to expand the database considerably, and encrypted passwords are now required. I can easily modify the web.config so all future users are set up with encrypted passwords. But is there any way to change all existing users passwords to be stored encrypted?

I'm using ASP.NET membership for a site that will serve primarily sophisticated users. I understand the difference between hashed and encrypted passwords, and I'm trying to decide between the two.After my last client complained bitterly about hashed passwords being a total PITA, I've started to favor encrypted passwords. But someone suggested this just isn't secure enough.So my question is: What, exactly are the risks of encrypting passwords? Any person with the ability to steal passwords by decrypting them from the database would surely have the ability to reset them if they were hashed, no? I'm having trouble seeing where someone could cause trouble with encrypted passwords but couldn't with hashed ones. Making it convenient for users is also important.

I am wondering how to encrypt the below information in the "web.config" file of the "Account" folder (where we have the secured pages):
[Code]....
My issue here is that even after I compiled my application (using "aspnet_compiler -v /reports c:
eports"), the information inside the web.config file of the Account folder still not encrypted, and I want to publish my site to the customer server. So, since this server is a customer server, then they can access this "web.config" file and change our web-application security behaviour (correct me if I am wrong). Basically, I don't want the customer to even have access to our secured pages when they access our web-application using the web browser. How to solve this issue?

I used the article Creating a Flexible Configuration Section Handler to create a Flexible Configuration Section Handler in my application.
I also saw this article entitled Encrypting Custom Configuration Sections on the OdeToCode blog, on how to encrypt portions of a web.config file.
From the first article, we have this web.config code.

I just came across some code that seems to encrypt database keys prior to sending them to the client (WebBrowser, Silverlight, etc).
To illustrate, suppose you have a list of students to extra-curricular activities, and a relationship defined between them. Every time the data is written out to the ASPX page, the studentID and activityID is encrypted. Every time a write, or modify is made, this value is sent back to the server, decrypted, and saved to the database.
What could be the reasons to expose data this way? Is this a normal practice?

Any section in my web.config file that I want to encrypt I run this command line util:
aspnet_regiis -pe "anySection" -app "/SampleApplication"
It all works just fine until I try encrypt my connectionStrings sections
I define (and I cannot change this) my connectionStrings section like this:
[code]....
Is there a way of doing this using the aspnet_regiis util? Doing it with code is not an option for me.
Also is there a way to run this untility without specifing the application (-app "/SampleApplication") instead giving the path to the web.config file?
