Doubt about dm_crypt

Elastic Stack Elasticsearch
1

Hi everybody,
I know that we can use dm_crypt with a basic license even if we will be out of support.
I would like just to know: where dm_crypt will perform the encryption? I mean, directly on the filesystem? who will be able to read data as a plain text?
in another discussion (How to use dm_crypt with elasticsearch - #2 by DavidTurner), I read:

Yes, dm_crypt transparently encrypts the data stored on disk so it looks like normal data to users of the host machine.

ok, data will be available from Kibana, from API but not from filesystem?

dmcrypt sits between the app and the filesystem. The wiki page goes into more detail.
