Which locking mechanism is used for Password-protect function of Pages app?
In this article (https://support.apple.com/en-us/HT207595), I can see that exporting to PDF uses AES-128 which is a baseline good sign, however nowhere has a detail of its normal document password protection using which algorithm.
Does simply password-protecting and saving it as .pages file still encrypt the file in AES-128 or 258?
