Master Key Encryption

Hi,

I would like to use OnlyOffice and for that I have to convert my encryption to Master Key. How does it work?

Here https://docs.nextcloud.com/server/12/admin_manual/configuration_files/encryption_configuration.html#occ-encryption-commands is written that only default encryption module is available while in owncloud it seems to be easily installed: https://doc.owncloud.org/server/latest/admin_manual/configuration/files/encryption_configuration.html#enabling-master-key-based-encryption

What do I have to do to convert my default encryption to master key? And what is the difference between both?

I’m using 12.0.4
