(JavaScript) Cape Verde Fatura Eletrónica XML Digital Signature
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
var success = false;
// 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
// you can simply load the XML to be signed from a file..
