Does anyone know if rclone supports encrypted cloud sync? That seems like a good solution.
Generally I think it is way easier to use any normal WebDAV storage, mount it and only write encrypted data in there.
Though, note that systems like cryFS, encFS or goCryptFS all either failed audits or haven’t had audits.
Many of the encryption tools fail, if an attacker has constant read access to the changing encrypted data.
The hardcore solution would be something like LUKS (you could use tomb here) or Veracrypt, where everything always changes. This will of course cause very high network traffic.
The new iOS and Android Filen apps based on their Rust redesign started launching today in the app stores. Sadly, their mobile github that hosted their apk releases seems to be archived now. I’m not sure if that will be permanent. I hope they maintain a way to get the new app outside of the app stores.
