c# can we detect if a pdf is signed

Can we detect if a pdf is signed before showing it on the PdfViewer. I want to check if the Document is signed by Handwritten Signature or a secure signature, I just want to see if it is signed.

Hi Luis,


We can find that whether the document is digitally signed or not. We cannot achieve it for handwritten signatures. We have shared a sample of this. Kindly refer to it and revert to us if you have any concerns.
