Dear list,
I have a question for users with more knowledge on digitally-signed PDF
documents.
Is it possible to concatenate PDF documents (each signed by a different
certificate [by a different person]) into a single PDF document without
invalidating any signature?
I tried to join all PDF files with pdftk, but digital signatures in the
resulting file were invalid.
I guess that I’m trying something impossible, but I’ll really appreciate
the confirmation from somebody with experience in digital-signed PDF
documents.
Many thanks for your help,
Pablo

Many thanks for your reply, Henri.
I saw that a way is attaching the PDF files to another PDF document.
My understanding of PDF Portfoliios is that they are only a fancy way of
presenting the attached files in the PDF.
I’m afraid that adding attachments to a PDF file would make life too
hard for the recipients of the file.
Many thanks for your help,
Pablo
