How to encrypt app.config config file in C#?

Question

Encryption

Can you please tell me how to encrypt data in app.config? Specifically interested in the section with connection strings, but in the general case it would be useful to know.
On the Internet, this method was found. But, as you can see, it is applicable only for ASP.net and IIS, which does not suit me.

In general, you can use any encryption algorithm for connection strings, the only question is, what qualifications are you hiding these strings from people :)
