The Security Inspector provides feedback about the permissions of the current document and whether the document is encrypted. It also allows entering passwords to unlock the document or to remove otherwise restricted privileges (printing and copying).
Note: Encrypted documents cannot be saved (in PDFClerk Pro format) or exported as PDF documents, nor can their pages be copied within the document. They can, however, be printed to printers or to PDF documents. If you want to edit an encrypted document over various sessions or with full editorial access, it is best to open and unlock the document, then print it to PDF and use the produced PDF document as the source for further editing in PDFClerk Pro.
