Hi Luis,
you need to calculate the signature over the whole PDF (without the
contents-data).
Therefore it's the best to
- fill the contents-field with a placeholder
- write out the whole PDF to a ByteArray
- calculate the hash-value and signature
- replace the /Contents-Data with the new data in the byte array
It's useful to do the same procedure (set placeholder-data / write out /
replace)
with the /ByteRange value, too.
Regards,
Peter
