Some documents shouldn't open for whoever happens to receive the email — payslips, medical letters, contracts, statements. This encrypts the PDF with AES-256 so it can't be opened without the password you set.
Lock a PDF with AES-256 encryption so it needs a password to open.
We can't recover it. The password is used to encrypt the file and is never stored anywhere on our side, so keep it somewhere safe.
AES-256, the strongest encryption the PDF standard supports.
