How to get a certification to sign PDFs

I'm trying to get a certification to sign my PDF files these days. My Goal:

  1. It is a certification signed by a trusted CA in Adobe Acrobat (of course it can't be self-signed)
  2. It is cheap
What I did: Check the current list of Adobe Approved  Trusted CA (http://helpx.adobe.com/acrobat/kb/approved-trust-list1.html) Check those CA's website. Many of those CA are used inside their company/organization only, Some "Widely known CA" like DigiCert, GlobalSign, Entrust cost a lot(200-800 USD/year) for the certification, and you maybe asked for purchasing a USB device for the cert, PLUS, some of them limit the number of files you signed. Finally I found "CERTUM (Unizeto Technologies)" in Porland, they supply a certification for a low cost(~10USD/year)  https://en.sklep.unizeto.pl/data-safety/id-certificates/certyfikat-professional-id.html (more…)
