Encryption on oxDrive

I read info about encrypting files on my drive here:

https://kb.mailbox.org/de/privat/drive/verschluesselung-im-drive/

Encrypting/decrypting files using this method is not convenient - are you able to tell me whether oxguard or simmilar solution is available for your suite?

My goal:

I'm using oxdrive on 4 devices, including mobile phone. I'm looking for a solution which would transparently decrypt files when I'd like to use it and would encrypt them again when no longer used.
