What is PDF encryption and what is it for?
Adds a password to your PDF files with 256-bit AES encryption, or removes a password you know. Useful when emailing documents such as contracts, proposals, payslips and invoices. Don't send the password through the same channel as the document; if the document goes by email, give the password by phone.
