Please share signed and unsigned pdf document.
How do you think I can find out where the problem is? I don't have a pdf document, I don't know your code - traceback alone is not enough information....

I was wrong. The document is signed with a root certificate. I think this is not a normal situation, but will add some code to check this situation.

Cut confidential data and send it to me (e.g. e-mail) - the document will not be legible or verifiable, but I will be able to see where and how the...
