Encrypting SQL Connection string in web.config file and retrieving it through ASP.NET code

I want to encrypt the SQL Connection string in web.config and retrieve it from ASP.NET code in a decrypted format.

I have come across DPAPI method, however, for decrypting looks like we need to run the command. I want to avoid this and have it retrieved in the code in a decrypted format.

How can I achieve this?

Thanks in advance.
