Then, what is PDF encryption?
Adobe PDF security uses encryption to protect PDFs and allows you to apply permissions to control what a user can do with a document (print or edit it). The PDF is encrypted with a password (the encryption key) but weak passwords can be easily removed with password removal software.
Subsequently, question is, how can you tell if a PDF is encrypted? If you know the password to the file, you can view the encryption type using Adobe Reader. Go to File -> Properties -> Security and click the "Show Details" button. See 'Screen Capture 1' below. The security tab will also show you what version of Acrobat can open the file.
Beside above, how do I encrypt a PDF?
Acrobat will open the document only after you have entered the correct password. Click "Advanced" at the top of the Acrobat window. Select "Security" and then click "Remove Security." Click "OK" to confirm the action and remove the encryption.
