I'm trying to sign a PDF with an external service. This service receives the
PDF's content (hash) and returns the signature (hash).
I followed the "CreateSignature" and "CreateVisibleSignature" examples and I
was able to make it works.
But, I need to sign the PDF in 2 steps: 1- Get PDF's content, calculate the
hash and send the hash to the service that is responsible to sign the hash.
2- Get the signature hash returned from the service and insert it into my
PDF.
Note that in the 2nd step I'm not in the same context from 1st step, so, I
can't access the PDF that was loaded in step 1. I would need to load it again.
