I have installed Boxcryptor Portable on my Linux system, and a small professional group I am part of is also planning to open a separate Boxcryptor account that a number of the group can access.
Before the group gets up-and-running with this, I have been getting used to Boxcryptor and the way it works for me. I downloaded and installed it as root, and have been invoking it as root. This is, I think, giving rise to two issues:
1) When, within an encrypted folder, I edit a document, I obviously get a version of the relevant program (LibreOffice Calc or Writer in my case so far) which has been invoked by Boxcryptor in a version as superuser, which in itself wouldn’t be too bad, but I lose the menu at the top of the screen for some reason, and I lose all the tweaks I made to LibreOffice in the non-superuser version.
2) Boxcryptor seems to suggest editing documents like this is not a good idea because of sync issues, and recommends decrytping the document, downloading it to the local machine, editing it, then uploading it again and re-encrypting it. That makes sense, but when I have a look at a downloaded and decrypted document, I cannot open it, as I do not have root privileges at that point.
Not only does this have practical issues for myself around editing documents stored in this way, but it also has implications as our professional group wishes to be able to access and edit documents stored via a co-owned Boxcryptor account, ie if I have stored a document there as a superuser on my system, presumably it would not be accessible by other users. To add further complication, I am using Linux, while my colleagues will be using Windows machines.
So my questions come down to:
Should I change permissions on my downloaded Boxcryptor Portable program, so that it functions for me as a normal user? If so, what would be the command to do that? How do file permissions function across different operating systems?
