Before you can add digital signature in PDF file, you need to get a digital ID, sometimes called a digital certificate. Certificates for digital signatures are normally issued by a trusted third party provider called a Certificate Authority (CA), who are certified to do this. Ordering certificates from Certificate Authority often costs you some money depending on the type of certificate you need.
