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.

Configuration :: Encrypting A Custom Section Programatically

Aug 11, 2010

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.

Configuration :: Encrypting ConnectionStrings On A Hosted Website?

Feb 23, 2011

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?

Configuration :: Encrypting ConnectionStrings With RSA Container On Remote Sever

Oct 22, 2010

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?

Security :: Using Authentication For Certain Sections Of A Webpage?

Aug 6, 2010

I currently have a website which I want everyone to be able to view, authenticated or not. But if someone does sign in, I want different controls and different C# code to be run on the page.

At the moment I have not put any asp security in. I just have two text boxes that check against the database then keep the user logged in using a session variable. Each page then checks to see if the logged in session variable has a user in it and runs the code.

I'm assuming this is not the most secure way, is there a way to do this correctly?

Security :: Encrypting Section In Web.config?

May 3, 2010

I am wondering how to encrypt the below information in the "web.config" file of the "Account" folder (where we have the secured pages):


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?

Security :: Encrypting Passwords On Client?

Nov 1, 2010

I want the login password to not be sent in plaintext (due to the risk of hijacking). I know that this can be achieved in principle using MD5 or the like, but is there a common implementation for use with Asp.Net? Of course, it's crucial that the resulting hash (?) isn't easy to decrypt. When I read various posts on this matter, some people say it's just to do a reverse on the encrypted string, so that in effect, this is totally useless.

Security :: Ways Of Encrypting Querystrings?

Sep 8, 2010

I have been looking at ways of encrypting querystrings and I have found a few good examples.. but, I just want some clarification on what is most often referred to as the EncryptionKey and the characters that are in that key....Is there basically an unlimited number of alphanumeric combinations that could be used in the following code as the encryption key, is there anything that someone should be CAREFUL about including in that key?

using System.Security.Cryptography;
private static string EncryptionKey = "!#$a54?3";
/// other examples: "r0b1nr0y"
///in a try-catch:
key = System.Text.Encoding.UTF8.GetBytes(EncryptionKey.Substring(0, 8));
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
inputByteArray = Convert.FromBase64String(Input);

Configuration :: Encrypting The Connection String In Web.config On Windows Server 2008

Mar 30, 2010

When I try to encrypt the "connectionStrings" section in the web.config file of my 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.

Security :: Deploying And Encrypting Web.Config On Server

Nov 12, 2010

I have written a couple methods that encrypt and decrypt the appSettings section of my web.config file using the WebConfigurationManager. I just hooked up the methods to the page_load event to test that it works, which it does. Now I need to deploy to a web farm and need advice. What is the best way to make it so I can encrypt, but more importantly decrypt the web.config when I need to? I thought about putting a hidden page with "encrypt" and "decrypt" buttons, but that seems risky. What is the "accepted" method for rolling out something like this?

I have a problem hopefully someone out there will steer me in the right direction.

I have a web application that I am going to put on a standalone cd - currently the data is "Safe" because the database is in in the app folder and the code is located in the codebehind.

My problem is i'm putting this on a CD as a standalone site, anyone can access the database, or find the XML....

Is there a way to generate an encrypted Database / XML Page, that is complied with the CD, that the program can decrypt and access with a embedded key?

Security :: Encrypting Passwords With T-SQL That Will Be Decrypted By Membership Provider

Mar 4, 2011

I have been killing myself over this for a couple weeks now and cannot find a viable solution. Here's my scenario:

I have a DTSX package that imports user data from an external database. It then creates user accounts and profiles in the local database. Users can also be created via a custom ASP.NET Membership Provider. The provider must be able to authenticate both types of users.

This was all fine and dandy during development because passwords were stored as clear text. However, now that we're ready for release the passwords format of the provider must be set to encrypted and so the users created via the DTSX must be created with an encrypted password. (I'd prefer the passwords were hashed but the client's requirements are that passwords be recoverable). The real problem seems to be creating an encrypted password within the DTSX that will be decryptable by the ASP.NET Membership Provider.

My original solution was to have the DTSX call a CLR stored procedure that had access to the same encryption logic as the provider. I got it working but our client wouldn't enable CLR integration. So that's out the window. Now I'm investigating alternatives. One alternative is to simply use the built-in encryption methods of T-SQL. But how do I share the keys used for the encryption/decryption?

My question is, is it possible to generate a password in T-SQL, say using EncryptByKey, that will also be decryptable by my provider? This means that the key in SQL must match the key in my machineKey configuration.
