Questions
How strong is the encryption?
AES-256, which is the strongest the PDF specification defines. The strength that matters in practice is your password, so choose a long one.
What if I forget the password?
The file is not recoverable — that is what encryption means. Store the password somewhere safe before you rely on the encrypted copy.
