PDFBox: Add metadata to signed document

[Alberto Malvido]

Hi,

Is there any way to add metadata to a signed document without breaking the
digital signature? If so, could you please point me to the right way to do
it?

The digital signature is performed with the following filter and subfilter:


   - signature.setFilter(PDSignature.FILTER_ADOBE_PPKLITE);
   - signature.setSubFilter(PDSignature.SUBFILTER_ADBE_PKCS7_DETACHED);

Thank you so much,
Alberto
