Signing PDFs in ColdFusion with CAC certificates

Question

Has anyone had any experience with signing PDFs in ColdFusion using certificates stored on a CAC?

I know you can manually import certs to the server, run some java commands to create a keystore, and eventually slap a digital signature on a PDF.

What I'd like to do is read the certificate data from the CAC via the browser and use that to populate a digital signature on a PDF using cfpdf - basically recreating the signing of a PDF in Acrobat but within my applications. I'm not sure if this is possible without a 3rd party tool like DbSign or manually moving around PDFs outside the application for signature.

Curious to hear of anyone's experience with something like this.

Cheers,

To save time/trouble for others following along but unfamiliar with a CAC, I suspect Paul is referring to the dod/gov Common Access Card (https://www.cac.mil/Common-Access-Card/). That said, I have no thoughts to offer on the prospect of pulling data from that, for such a purpose as he proposes.
