Hi, thank you for the reply.
pensadov1:Hi, thank you for the reply.I understand that Aspose.Pdf supports digitally signing PDF documents. However I don’t see in the documentation how to include a timestamp from a time stamping authority (e.g. GlobalSign).
currently not supported but for the sake of implementation, I have logged this

Is this feature already supported? I’m interested in it too.
