Hi Tamas,
I saw your posting in the mailing lists, I am also having the same scenario, but I am getting the error, "Unexpected Byte Range".
My scenario is,
I have to make a hash out of the pdf and send to an external entity, which creates the pkcs7.
I have to insert the pkcs7 into the original pdf.
I've followed the sample "how to sign with external siganture", except for the code, which generates the signature, I've put the generated pksc7 bytes. I keep getting the above error, "Byte Range is invalid."
Are you able to successfully attach the signature with the original pdf.
regards
siva
