Hi!

I am programming in vb.net and would like to know how I can simply
verify the presence of a signature on a PDF ? I don't need to validate
the signature, I just need to know that the PDF is signed.

I made a little search my-self and I think I should use the DigSig API
(Digital Signature Extended API). Is this accessible with Acrobat
Professionnel 7 ? Or do I need the SDK 7 ?

Thanks for your help.
