Encrypting DataConnectionString

I would like to encrypt the DataConnectionString and decrypt it at runtime when called or needed.  Given how resourceful hacking can be, I think it is too vulnerable inside the App-_Data folder in plain text.  I am able to do this on my other .NET Core apps with an encrypter and a decrypter method; however, I am looking at the database calls in NopCommerce and can't seem to figure out where to decrypt the connection string.

Has anyone tried to do this with nopCommerce, successfully?

I would imagine you would be modifying

     public partial class DataSettingsManager

          LoadSettings routine would de-encrypt
     and
          SaveSettings routine would encrypt

@Yidna,

Thank you for the reference.  Utilizing the LoadSettings() Method, I was able to secure my SQL Server Connection String.  :)

Have a wonderful day!

Johnny

thanks for this good idea.
Can you share the code of encryption and decryption.
