Signature requires validating...

Post by lidds » Sat Feb 17, 2018 12:07 pm

I am a bit confused as to why when a document is opened in PDF-XChange Editor it keeps on prompting me that "At least one signature requires validating" when if I open the same document within Adobe Acrobat Reader it says the signatures are Valid?

Hi, probably Adobe Reader verifies the certificates on opening, while PDF-XChange Editor notifies about the missing verification.
You can change PDF-XChange Editors behavior:

Thanks Big Mike!

I was half way through making that same shot when I realized you've already provided it!
Indeed lidds - you can turn the option BigMike showed you on, so that we also try to validate signatures at the time you open a document with one.
