Encryption enabled. How does impersonate still work? 1. Assuming I have a user and an admin
2. The admin enables encryption using the default module
3. The user uploads some files
4. Nextcloud encrypts the file with user provided entropy, like the password (?)
5. The admin uses the "Impersonate" app to look into the users files
6. He can see the files

Why does it work? I mean shouldn't only the user be able to see his files in the clear?
How can I verify if nextcloud actually encrypts data?
