PDFSign Plugin Allows you to create signed or timestamped PDF, PDF / A and ZUGFeRD documents using the eDocPrintPro printer driver. The signature can be applied visibly or invisibly. The product video shows how it works.
PDFSign can sign PDF, PDF/A, and ZUGFeRD documents with a X.509 certificate and maintains PDF / A compliance. Create a visible signature with multiple options, timestamp, self-signed certificates. Available as a command line, folder monitor or REST/SOAP web service application.
