Sign pdf hidden

Post by marcel »

Hi, first of all best wishes for 2023.

It's probably very simple but I can't find it.
Is it possible to sign a pdf file with a digitial certificate "hidden".
So without a visual widget. if so, are there any code examples of that?

Hi Marcel,

I also wish you all the best in 2023!

Please read how to add digital signature to PDF document here: https://www.vintasoft.com/docs/vsimagin ... ument.html

If you want to create "hidden" digital signature, you need to hide interactive field that represents digital signature. Also I think it is possible to create interactive field without visual representation.

Best regards, Alexander
