All that information is inside the PKCS#7 signature - so you'll need to use the crypto-provider APIs.

The signatures can or cannot be signed with an external timestamp. The timestamping itself works flawlessy, but how can I, when I open a PDF again and get the certificates, extract the timestamp information again (precisely: if there is an external time stamp, what server and the certificate)? Is there any sample code or does anyone have a solution for that already? Best regaerds and thanks Rog -- * The most important single aspect of software development is to be clear about what you are trying to build.
