I have web.config file and it is encrypted completely and hosted in one server,Now I got one requirement to change admin person mail id. So I need to decrypt the web.config file and update the mail id then encrypt the config file again. Please tell me how to do this using aspnet_regiis -pdf commands?
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!
I used the following command to encrypt my connection string but an error ocurred, "The connection name'DatabaseConnectionString1' was not found in the applications configuration or the connection string is empty" How can I encrypt it while keeping the application working? What if I move the encrypted application to another computer? Will it work?
I have to Encrypt and Decrypt Back the Password field in sql server i have used the pwdencrypt and pwdCompare() but i dont have to compare but i have to display the password back using the Decrypt technique Is there any algorithm which i can use only for encryption and decryption of password field?
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 have requirement to encrypt the windows service config file and web.config connection strings, I could able to do that for web.config with aspnet_regiisC:WindowsMicrosoft.NETFramework64v2.0.50727>aspnet_regiis -pe "connectionStrings" -app "/application.ui")But I am still looking similar kind of way for windows service config file to encrypt and decrypt..exe.config file snippet as below
I was reading about how it is a good idea to encrypt the connection strings for security purposes. I came up with a solution that I think may be somewhat elegant, but there may be big flaws in my thinking. I am overworked and tired :)
Basically I have a setting in the web config EncryptConnectionString. In the Global.asax. Application_Start I am checking this in the config. If it is true, I am encrypting the connection strings. If it is false, I am decrypting the connection string.
I Actually want to simulate like those using asp.net(crypting string or image), but i don't know what is this type of encryption, and how i can generate, i would be grateful if I just know the name of it.
I want to encrypt the connection string in web.config, the problem is each time a developer changes the connection string in web.config and publishes, it needs to be encrypted every time in the web server. Is there any way that the connection string can encrypted automatically every time someone publishes it?
Note :- All of us work on our local machines other than the server. So encryption using local machine key is not an option.
When you need to store sensitive data such as CCs or SSNs, do you:1) Build your own encryption routine within the application, define a secret key somewhere in a config file, and then manually encrypt/decrypt data going to the database.2) Push all the problem to the database, using the built in DB capabilities (I think most vendors call it Transparent Database Encryption).What trade-offs have you find for your solution? Does writing your own routine perform poorly when compared to TDE? Is code maintainability, or conversely DB vendor lock-in an issue?
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
I'm using webservice to integrate asp.net app with PeopleSoft. Sometimes, the value that I get from a querystring (eg in url below, request id =7) and pass it to PeopleSoft via webservice is blank, although the querystring contains key value pair. This causes the webservice integration piece to fail. What can cause this issue where the querystring value is blank? and how can I fix it?
