Add "Digital Signature is OK/not valid" to Info Tips?

I have Directory Opus configured to show an Info Tip when I click on a file in a Lister and press the CTRL key. Is it possible to have Directory Opus check if that file has a Digital Signature when I press the CTRL key key, and if it does, display whether the Signature is "OK" or "not valid" in that file's Info Tip? Thank you for any help.

I don't think there is currently, unless you can find a shell extension or Explorer column that adds it as a column or property, or a way to do it via JScript/VBScript.

(The WShell "Scripting.Signer" object built into Windows is promising but it displays a confirmation dialog every time you use it, making it completely useless for the task. Maybe there are other ways.)
