Digitally Sign word document with a certificate

Question

I need to programmatically sign a word document.

I tried to find something like this in VSTO, but there is only Signatures.Add/Signatures.AddNonVisibleSignature which just shows a dialog to choose a certificate.

I have to achieve this in a ribbon. Office.Signature objSignature = signatureSet.AddNonVisibleSignature(); this is showing the user to select a certificate from the user store, rather i should be able to pass the certificate object to the sign API.

Is this possible ?

Hi,
Check sample code in this document to see if it helps.  It used signature provider ID.
