Cape Verde Fatura Eletrónica XML Digital Signature
See more XML Digital Signatures Examples
Demonstrates how to sign XML to create a signed invoice compatible with the Cape Verde Fatura Eletrónica requirements.Note: This example requires Chilkat v9.5.0.89 or greater for a small feature to provide the ability produce mult-line base64 signature ending with
Chilkat B4X Downloads

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.
' First create the following XML to be signed. This can be created programmatically as shown in the code below, or
