Question about .docx password security in libre office.

Hi,

I use Libre Office regularly and for compatibility with my friends I save
documents in .docx format with a password.

I use Libre Office Version: 5.1.4.2

Do Libre Office protect password encrypted .docx documents with 128-bit key
AES protection when the .docx documents are made with Libre Office and not
with Microsoft Office ?

Thanks in advance for your answer.
Vladimir.

A addendum: Does the answer change for documents saved in .doc format?
