Questions
How strong is the protection?
AES-256 encryption, the strongest standard PDF encryption. Use a long password: a short or common one can be guessed by password-cracking software.
I forgot the password.
We can't recover it, and nobody should be able to — that's the point of encryption. Keep a copy of the unprotected file somewhere safe.
