Hi,
I am not very sure about how iText works deep inside, but I wondered if is
it possible to create a signature without having access to the PDF
document's content, but for the digest of it, and that this signature could
be applied later to the final PDF document?
See this:
*Procedure 1 by Application A:*
[FULL PDF] -> Extract Digest -> [DOC's DIGEST]
*Procedure 2 by Application B:*
[DOC's DIGEST] -> Create Signature -> [DIGEST SIGNATURE]
*Procedure 3 by Application A:*
[DIGEST SIGNATURE] -> Apply Signature -> [FULL PDF]
Thanks in advance.
