Thanks a bunch for the technical reply.

Veracrypt is intended for local file system encryption. Do not use it for cloud encryption. You will need to reupload the entire encrypted file that encapsulates all your encrypted files every time you make a change, which eats a lot of date/bandwidth as it increases in size.

I have unlimited gigabit internet so I wouldn’t be too worried about that, although accessing said cloud drive from another machine I might soon run into problems, so that’s really good to know.

You probably want something like cryfs or cryptomater, like the other commenter mentioned.

CryFS and Cryptomator both look perfect for cloud encryption indeed. Surprisingly I’m leaning towards CryFS. I’ve really gotten to love the mounting of RAR files (rar2fs) and other compressed archives (archivemount-ng), so CryFS looks just like what I’d prefer - but Cryptomator has an android and better windows version which sounds more handy…

Quick look around and it looks like DroidFS supports CryFS, so I think I’ll take my chances.
