Hello, In my company we are PDF maniacs 😃, We generate any data using PDF, Usually we use word to make the file, and "print" it to a "PDF File Printer", that produce the PDF files for us.
Then all the reports and dinamic files GENERATED by the web server at the Intranet, are generated using PHP with PDFLib.
So far everithig is perfect, but the files generated by PDFLib can be edited!, can be modified, and can be printed!. Usually with the pdf printer, all the files are protected to avoid Modifications. Some to be Readed (with out a password), or printed with out an other password.
But How can I do this to the files I generate in PHP ?
(I know their can be cracked, but that's an other history. Right now I need to protect them, at the most possible 😃 )
