What Is a Secured PDF?
A secured PDF is essentially a document encrypted to restrict any changes or actions on the file. Securing a PDF with a password or encryption is an added layer of security to ensure your PDF is authentic.
- A password-protected PDF: restricts the PDF file only to authorized users. If you’re allowed to open and view a password-protected PDF, you have a “Document Open” password. If the PDF restricts printing, copying, or editing the PDF meanwhile, then you have a “Permissions” password-protected PDF.
- An encrypted PDF: uses encryption and access codes to hide important data within the file. Only authorized people can see the encrypted information by using a password. Once a PDF document is encrypted, it will require a cipher and a key to allow users to decrypt the data stored within.
