Using `age` or `rage` is deadly easy. Also, e2e is most effective when it happens out of band - if the idea is "I don't trust Dropbox, so I want client side encryption" then you shouldn't trust them to do the e2e anyways. I realize it can be more complex, but managing it yourself gives you the maximal benefits of e2e.

I agree if you care about security it's better to DIY, it's just not simpler than say putting a file in Proton Drive

It's not just "better", it's the only approach that addresses the real threat model. So you can go with something simpler like checking a box but then you aren't getting the same feature.

FWIW this is the reason, to my understanding, that Dropbox has always been reluctant to support this feature - because if you actually want E2E you probably want it out of band.
