[PVE-User] Where is ZFS encryption key in Proxmox 7.1

[Eric Abreu]

Hello everyone,

I have created a ZFS pool from Proxmox 7.1 web interface with 2 SSDs in
RAID 1. I noticed that everything works fine after I created the pool, and
ZFS at REST encryption was also enabled. After rebooting the server it did
not ask for a passphrase so my guess is that Proxmox is getting the key
from somewhere in the file system. Anyone could help me find out where?

Thanks in advance.
