How to extract digital signatures from PDF?

It seems like it should be such an easy task - or at least previously asked somewhere, but I can't find anything useful. Is there a command line utility that will give information about digitally signed pdf's?

So far, I've tried only PLOP DS, but it gives the following:

Signatures: 1
    invisible signature field 'sigField': signed

Is there anything else to try?

Take a look at iText, its a library for creating and manipulation Pdfs in Java. You can find some useful examples about signatures here: http://itextpdf.com/examples/iia.php?id=222 (see verifySignatures() method)
