Is there a software or functionality on Fedora that supports creating and using some kind of encrypted container for a file, preferably supporting GPG encryption? Or some abstraction layer that lets programs like LibreOffice edit GPG encrypted files?
I am editing a few files and sharing them via cloud. Currently I copy the file to an offline folder, decrypt it manually, edit it, then encrypt it with my and recipient’s key and copy it back to the network share. The copying and decrypting/encrypting is a little tedious and I’d like to skip it.
