PDF digital signature

Post by mael15 » Tue May 25, 2021 9:54 am

I create PDFs using wxPdfDocument. Due to a new law/regulation/certification in Germany I have to find a way to add a digital signature. Is there a way to do this without using some other tool after creating the PDF? I would like to create and sign it in one go without the user of my app having to click some more.

Unfortunately, wxPdfDocument doesn't support adding digital signatures to generated PDF documents. And this isn't going to change anytime soon, although I have plans to enhance wxPdfDocument in the course of time. So, for now you will have to use a separate tool to accomplish this.

I suppose you need a component that you can add to your application somehow. Most solutions I know of are commercial - ranging in prices from one-time fees of 500 USD to 3000 USD/year. The open source library PoDoFo claims to support digital signatures, but I haven't tested that for myself.
