I am new to Digital Signature functionality.

I have a .PFX signature file with me. I need to generate digital signature using the file and append it to an existing PDF file.

I have used TCPDF with FPDI to get the content of existing PDF file and append new content to it.

I need the steps on how to generate signature and append it to the existing PDF file.

Also i am facing issue in appending content using FDPI. When trying to append it is overlapping the existing content means it starts appending content from page1. To avoid i need to add a new page to append the content. Is there any possibility to append the signature and some text content at the end of the existing content?

Is this pdf digital signed correctly? PHP/TCPDF

Take a look in my solution, I think will resolve your first question.
