Hi
I use Picocrypt-NG but I discovered that it is vibecoded, which is huge no-go for me, especially in so sensitive task as encryption.
Can you please advice me good GUI (because I am a beginner) utils for Linux to encrypt files? And better without sudo, because I don’t feel comfortable allowing any app to have root rights on my distribution permanently.
I need exactly file encryption, so I can upload them to cloud (backup)
So… Any good ideas? I am complete newbie

Have you seen https://github.com/FiloSottile/age/, usage is basically one line.
Or, for GUI: gocryptfs

I see one of our “Experts” is already helping you out on this topic so I’ll read about this with interest, since it is not one of my areas where my current experience level is strong. By the way, reading about technology, then trying things out has served me well for decades; I tend to be a generalist and there are more things that I don’t know than things that I know for certain, but participating in very good forums like this one helps me keep my aging brain functioning reasonably well!
