Hello I've noticed the default encryption in the Windows application is AES256-CBC. From what I can see on the web, AES256-GCM replaced AES256-CBC with OpenVPN > 2.4 , is less ressources consuming and also less vulnerable to some kind of attacks. I can't state these myself, as said it's obon what I've found. But if all of these are true, is there any reason or preference to use AES256-CBC as default choice? Is there any drawback to use AES256-GCM instead AES256-CBC with perfect-privacy? Thank you.
