Question 1

What encryption strength does Protect PDF use?

Accepted Answer

AES-256, the same standard used by banks and password managers. Strong enough that brute-forcing a good password is computationally infeasible.

Question 2

Can I set print and copy restrictions separately from the open password?

Accepted Answer

Yes. Set an owner password to control printing, copying, and editing — even after the file is open.

Question 3

If I forget the password, can I recover the PDF?

Accepted Answer

No, and that's the point — there's no backdoor. Store your password somewhere safe before encrypting.
