So, how can we provide a timestamp server to use when the document is being Cert signed?
The document will be invalid after the Code Sign cert has expired if it doesn't have a time stamp. Not really sure what good this feature is without the timestamp. I can't imaging saving all the originals so that I can resign them, when our cert has been renewed in a couple years. This won't work for anyone in the medical community using signatures.
Of course you are right, but for security reason, we do not want our dll to able to make an external call.
After discussion with my CEO , I am starting to find a solution where the external call to the timestamp server should be done by the final application.
The process should be something like this : provide all information needed to sign the pdf, ask GdPicture for a footprint , here it is for the application to make the external call to the the timestamp server with this footprint and wait for the answer, and then the sign with the returned answer.
Due the complexity of the signing process, it will take some time to be implemented.
