I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

Ok I created a web app with membership & role, intially I had 2 db but combined data with the default aspnetdb.mdf created to simplify.I then used "copy web" to move all asp files & roles folders to remote server in a sub domain directory.Created a backup of the aspnetdb.mdf and then ftp to sub domain directory which was then loaded by the host as MS SQL db name: aspnetdb3.Now, I know I need to change the web.config connection settings but to what???here is the initial connection setting:

My boss does like storing the connection string and credentials in the web.config - even when its encrypted.
He also doesnt want the IIS box and SQL box to both be in the same domain, or have trusted domains.
Is there a more secure method of connecting to SQL? Is there some kind of token login?

I have been searching internet in order to secure my connection string in the web.config file and setting the Login controls connection strings in runtime
TEverything about encrypting connection strings works fine on local machine. I can do it programmatically and on aspnet_regiis.exe
My questions are How can I set the connection string to any login control in runtime? How can I encrypt my connection string on my shared hosting ?How can I use aspnet.regiis.exe to encrypt my config file on shared hosting ? How to define the commands ?If I can find a solution to my 1st question, 2nd doesnt matter anymore.

i am receiving this error when trying to use my membership provider: After googling the error most peoples problems are fixed by removing the old connection string first but this has not worked for me.
I have used a simple custom memberhip provider with one table.
On shared hosting with 123-reg.
The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Configuration.Provider.ProviderException: The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.

I have a very basic web site that uses a standard login control. It was original built using ASP.NET 2.0, and when I preformed a few site improvments, VS 2010 upgraded the site to version 4.0. Locally, everything is fine. But live, everything is working except the login authentication. All other pages that use the database work fine.
does the upgrade process affect the database? As this is the only thing I've not replaced on the live server.
The error I get with the login is:
The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file Any thoughts?

I have looked for ideas on this and read several posts but none of them seems to be because the problem is that web.com (my host) doesnt allow us to update web.config on their server programmatically. I can use example codes and encrypt them on my local pc but heres the error i get when I run them on the live site:
An error occurred loading a configuration file: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. (machine.config)

In the web.config, how do add a connection string by using a window authentication with the username and password? I have tried like this and it keeps ignoring the username and password
<connectionStrings>

This is meant to be easy ...so ive been told, but still cant get it to work!I have a sql database hosted on a shared server which requires the use of sql authentication.As a result I require to encrypt my sensitive data in the config (connection strings etc).I understand that you can do this using aspnet_regiis etc, but ive been told that as I have no direct acccess to the server, I may need to program the encryption.
I have seen a few examples, but as a novice I have been banging away at this, looking at an errors screen most of the time!

My problem is that I'm going to have a SQL Server database and website that accesses that database via a hosting provider, most likely GoDaddy.com, using ASP.Net. I need to make sure the connection string in the web.config file is as secure as possible, because the database will actually be storing trivia questions for a game I'm developing, and the clients will be accessing these questions, saving specific state related details, and other details, to the database, so every player that plays the game will have their details stored in this database. I need to ensure hacking is very difficult to accomplish.
From my research it appears as though the only viable solution for your web.config when you've got a hosting account with something like GoDaddy.com is to use SQL Server security to connect to your SQL Server database and place those details in the web.config file. Is this correct? It seems that this is the most likely scenario for most users, because we don't have access to our hosting providers IIS servers in order to use Windows authentication with SQL Server access and then use DPAPI encryption from there.

I have a Triple DES Key generated by java code from a third party vendor. It is a 3 part key.
We need to use this key in our VB.NET application. When I try to combine this key and use it in my app
'Dim desTransform As ICryptoTransform = desCrypto.CreateEncryptor(EncryptKey(Key), EncryptIV(IV))' gives me an error ' Specified key is not a valid size for this algorithm)
I am new to cryptography and do not understand the algorithms well. How can I use the java generated key in our app for encrypt/decrypt.

In asp.net mvc project I am using MYSQlMemberShipProvider. Now I want that instead of reading the connection string from web.config file, it will read the connection string from external file every time. So that I am implementing the cutsom mebership provider class, this class inherits the MemberShipProvider class. But the problem is that if I inherits the MemberShipProvider class then I have to impelment all of its method in my cutsom membership provider class, But I want to use all other inbuilt methods of MemeberShip. What can i do. I only want to add the code like below:
public class CustomSqlMembershipProvider :MembershipProvider
{
public override void Initialize(string name, NameValueCollection configs)
{
base.Initialize(name, configs);
Connectionstring objProducts = // redaing the connection string.
}
}
But on compiltaion it is giving me the error does not implement inherit abstract member.

For our website, we have decided we would like to maintain our user passwords as encrypted binary data in our database. We are using ASP.NET 3.5 to host our site and SQL Server Express 2008 for the database, both running on the same server. When a user logs in and submits a username and password, there will need to be some sort of encryption or decryption in order to verify the credentials. To me, it would appear that there are 3 ways to do this:
1)[C# Encyrption] On User creation, perform encryption in the Web App and submit the encrypted password to the database. To verify credentials at Login, perform the same encryption on the submitted password and ensure that it matches the value stored in the database.
2)[SQL Encryption] On User creation, submit the plain-text password to the database and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, have the database perform decryption on the password during the SELECT statement, and compare the plain-text submitted password to the one in the database.
3)[Mix] On User creation, submit the plain-text password to the database, and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, perform the same encryption algorithm used by SQL on the submitted password ( is this possible? ), and ensure that it matches the value stored in the database.
Does anybody have an opinion as to which of these options is best? Number 1) is the most familiar to me, and would be the easiest to use with LINQ to SQL ( which is our current data model ), so I am leaning towards that. But if there are better options I would love to know about them.

I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
