Hi,

I'm considering to use this library to work with PDF documents, but I need to sign PDF documents using certificates saved on smartcards (Not possible to retrieve the private key, you must sign using external Hash of the document), and I also need to attach timestamping and OCSP check to the signature.

Is this possible with QuickPDF?
Thanks.

It's not possible to apply a server timestamp to a PDF file using Quick PDF Library. When you sign a file using SignFile a local timestamp is applied from the clock on the signer's computer.

In the future we might add support for server timestamps, but not in the short-term.
