Currently other GemBox components (except GemBox.Pdf) have a support for encrypted PDF files, see:
- GemBox.Spreadsheet's PDF encryption example
- GemBox.Document's PDF encryption example
- GemBox.Presentation's PDF encryption example
This feature request is for adding the support for PDF encryption in GemBox.Pdf as well, so that input PDF files can be saved as encrypted output PDF files.
This feature request has been implemented and is available in the latest versions of GemBox.Pdf.
