I have a pdf document that shows as "password encrypted" by OSX under its security label. Since I can open the document without a password I imagine a more accurate description would be RO password protected. When I try to merge this document using phpdocx with another pdf document (no protection) I get the following error; TCPDF_PARSER ERROR: decodeFilterFlateDecode: invalid code. GhostScript is however able to merge the two documents without issue. Is there a way to merge the documents using phpdocx?

Hello,

encrypted/protected PDF documents can't be merged using the current version of phpdocx. Please check the information available on https://www.phpdocx.com/documentation/cookbook/repair-PDF about this limitation. Using gs or pdftocairo those encrypted/protected PDF documents can be repaired.

Merging protected PDF documents in mergePdf is a work in progress that is not ready to be used in production.

Regards.
