I used FX File Explorer on Android and there is a feature that is kind of like adding a network drive but over the internet. You specific the address, login, password, and path. I've written a couple (very shitty) web apps so I know it's possible to set this up like this, but this is the kind of thing where businesses usually say it's not supported or it's not possible or whatever because they don't want to have to help a million people doing it. The UI is most likely doing exactly what I'm trying to figure out. I just need to maybe dick around with the browser dev tools a little more.
I guess I need to figure out exactly what the protocol is that's used when logging in. I tried just sshing to
api.boxcryptor.com and it tried to connect. I mean, it didn't just immediately refuse the connection. I actually had it set up where it was just telling me the password was bad. I'm going to need to fire up Zap/Burp and see what the traffic actually looks like though because at this point I'm kinda just guessing.
I just exported my keys and I'm looking at them. Think I might try to format the public key how they are in
.ssh. I'm sure there is a much better way to go about figuring this out, but I just don't have enough experience with it. So, please, if someone could chime in with anything that could be helpful even if it's just an idea on where to look that would be really appreciated.
Boxcryptor for Android is otherwise too awkward in my opinion to be as useful as it could be. That's mostly just due to the form factor and how Android is made so I'm not complaining. I still really want to figure this out though.
