Encryption / Decrypting Web.Config

Hello,

I have a script below that will encrypt and decrypt my web.config file.
My question is if I have the web.config encrypted, how to I access the database name, username and password when I need to access the database?

Do I need to run the decrypt code everytime when I open up a database source?





code:
Public Sub Encrypt()
        Dim confg As Configuration = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
        Dim confgSect As ConfigurationSection = confg.GetSection(section)
        If confgSect IsNot Nothing Then
            confgSect.SectionInformation.ProtectSection(provider)
            confg.Save()
        End If
    End Sub

Public Sub Decrypt()
 Dim config As Configuration = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
        Dim confgSect As ConfigurationSection = config.GetSection(section)
        If confgSect.SectionInformation.IsProtected Then
            confgSect.SectionInformation.UnprotectSection()
            config.Save()
        End If
End Sub

Thanks

Why not decrypt it and grab the value from the file when your application starts? You encrypt the file so that someone who has access to the filesystem (be he authorized or not) cannot see your DB login credentials by simply opening the file. Someone would have to scan the memory of your machine to actually see the unencrypted values while your program was running.

you don't need to decrypt, actually there should not be any decrypt code ever in the application. it should only encrypt. the idea behind encryption is so that no one can see what is written in the section. When ever you will access any protected section, it will automatically be decrypted and value will be returned to you.

For example, if you encrypt conn string name conn, then to access it you only need to do:-

configurationmanager.connectionstrings["conn"];

that is it.
