Topic: Extracting digital certificates from a PDF document

I am working on a plugin for Acrobat...
I want to get all the certificates from a PDF document. Certificate's may be from any Signature Field, signed by any plugin.
My requirement is to gather all the certificates from a PDF document as soon as it is opened and then send those certificates to an OCSP responder to get the revocation status.
I have finally come to know by reading the documentation that Cos layer contains the signature fields, and there is somewhere exists a signature dictionary, but still I couldn't get to know how can I get the certificates from all the signature fields... having just the AVDoc object (which I get in the MyAVDocDidOpen callback)
