2019-10-22Parse Contents in signature dictionary without encryptionMasamichi Hosoda
Various PDF digital signing tools do not encrypt /Contents value in signature dictionary. Adobe Acrobat Reader DC can handle a PDF with the /Contents value not encrypted. Write Contents in signature dictionary without encryption Tests ensure that string /Contents are not handled specially when not found in sig dicts.

2019-10-22Add QPDFWriter::getWrittenXRefTable()Masamichi Hosoda

2019-10-22Exclude signature dictionary from compressible objectsMasamichi Hosoda
It seems better not to compress signature dictionaries. Various PDF digital signing tools, including Adobe Acrobat Reader DC, do not compress signature dictionaries. Table 8.93 "Entries in a signature dictionary" in PDF 1.5 reference describes that /ByteRange in the signature dictionary shall be used to describe a digest that does not include the signature value (/Contents) itself. The byte ranges cannot be determined if the dictionary is compressed.
