I'm trying to create a simple pdf using self-signed signature encryption method in php with tcpdf
and open that pdf threw digital ID.
I'm running example 016
in TCPDF
library but an error occurred, when I opened the PDF with Acrobat Reader with installing .p12
certificate. :
"File Type Error"
My code is look like this:
$pdf->SetProtection($permissions=array('print','copy','owner'),$user_pass='', $owner_pass=null, $mode=1,$pubkeys=array(array('c' =>'file://data/cert/test.crt', 'p' => array('print', 'copy','owner'))));
