Currently other GemBox components (except GemBox.Pdf) have a support for digitally signed PDF files, see:
- GemBox.Spreadsheet's PDF Digital Signature example
- GemBox.Document's PDF Digital Signature example
- GemBox.Presentation's PDF Digital Signature example
This feature request is for adding the support for PDF Digital Signature in GemBox.Pdf as well, so that input PDF files can be saved as digitally signed output PDF files.
