I want to signature my Pdf''s.
I use the Flow-Model to generate my PDF and want also a digital signature.

I test the example from the Help, but it doesn''t work correctly.

Is the pfx-file from the evaluation center valid?
When I use the example from evaluation center, my PDF shows me an error like "Error in signature check".... And the icon has a question mark on it.

And how about pfx-files. Where can I get one.
Is is right, that I can generate a pfx-file from a valid cert-file? An example shows me, that I can generate a pfx-file from Internet Explorers "Certificate Management".

Sorry for my bad english. ;-)

Of course, I have a screenshot of my pdf.
This red cross comes when I click on the symbol with a question mark.

Perhaps it''s normal in the example of pdf-signature?
Because of the incorrect pfx-file?

Hi Erich,

Thank you for your interest in Essential PDF. Take a look at the following link to create a Self-Signed Digital ID [pfx file]


Regarding the error with digitally signing the document I am afraid I was unable to reproduce it, can you please take a look at the following flow model sample

and let me if the problem still exists.

Best Regards,
