Adobe Sign created PDF "Certified by" Metadata in API or XML

[Brian24427893c287]

Hello all,

I'm attempting to validate some PDFs created by the Adobe Sign service (sent from the Adobe Sign web app), specifically I am trying to figure out if I can validate the "Certified by Adobe Sign a Document Cloud solution..." message/security seal without having to open the PDF in Adobe Acrobat.

Is anyone aware of a way to access this Metadata via the Adobe Sign API or from XML that's part of the PDF? If this can be accessed via XML Metadata from the PDF, is there a good program to use to access it? Please see red outlines in the attached screenshot for what I'm talking about.
