Networking Information (Protocol, Ports, Encryption, Communication route)

Hello there, I am considering purchasing one of your devices, namely, WD MyCloud Home 4TB.
But I would appreciated if you give me further information about the product as I have not been able to find them in your documentation.

1- The communication between client\s & MyCloud Home 4TB, what protocol is used, is it encrypted, what ports, and route is it directly from client & mycloud Home or via WD?
2- Can I encrypted mycloud home hard drive if it gets connected to my Winds 10 Pro PC?
3- What hard drive is used HDD or SSD?

Thank you very much in advance…

The data is stored locally and WD does not have access to the data. Internet connection is required for account authentication.
