[SOGo] OpenPGP.js support

["Rothlyn Giles"]

Hello everyone!
I'm currently using MailCow, which includes SOGo, and I'm looking to secure it 
as much as possible. During my first-time experience with this self-hosted 
email server, I've only found outdated posts from 10 to 16 years ago.
Is there an easy way to use OpenPGP with SOGo? It seems that support is only 
mentioned for Afterlogic. If OpenPGP isn't supported or planned for SOGo, what 
methods are people using to secure their email in the browser and beyond?
Thank you!
