How to add digital signature to pdf

Question

I'm using MPDF library to generate pdf documents, Now I want to add digital signature extension with .pfx file into the pdf document. I searched over the internet most of the suggestion are showing as TCPDF, I don't want to use the TCPDF library. I want to continue with MPDF library for some reason.

Answer 1

mPDF does not support signing documents yet, so you will have to use another solution - either switching libraries, or appending a step to your PDF generation process.

There is an open feature request https://github.com/mpdf/mpdf/issues/389
