"Document has been altered or corrupted since it was signed" right after signing
I'm trying to sign PDFs using a digital signature from a smart card.
Right after the file is being signed, I'm seeing "Document has been altered or corrupted since it was signed" error.
Signing the file with a self signed digital signature on file works just fine.
Signing the file with the smart card signature works just fine in Foxit PhantomPDF and Comsign Trust Desktop.
I'm using Adobe Acrobat Pro DC 2019.010.200064.
I saw a previous discussion with a similar error that was not resolved.
1. From the name of the user that openner the thread it seems where both from Israel. Could it be related to some timzone issue?
2. It was suggested on this thread that it's LTV related. Is it possible to disable LTV, i.e. make Acrobat not add LTV information?
