Hi All,
I have a program which take the initupload.xml for JPK_VAT and sign it using a sample digital certificate stored in .PFX file.

My user is using certum digital signature and they are saying that the certificate is on card and cannot be exported as .pfx file.

can anyone suggest what i need to do to get the digital certificate in .pfx file ?

This is for JPK_VAT submission for Polish Government
