Definition
A digital signature is a cryptographic mechanism verifying the authenticity and integrity of an electronic document. For e-Faktura in MK, the XAdES (XML Advanced Electronic Signatures) standard is used.
Details
Digital certificates are issued by authorized issuers (KIBS, Makedonski Telekom). Valid for 1-3 years and must be renewed. For e-Faktura, the signature is added to the UBL XML document before submission to UJP. Levka automatically adds the digital signature.
Example
You create an invoice → Levka generates UBL XML → automatically adds XAdES signature with your digital certificate → document is legally valid and ready for UJP.
