Create XAdES-EPES Factura Electrónica Signature
See more XAdES Examples
Demonstrates how to create an XAdES-EPES signature. The sample data is for the Costa Rica Factura Electrónica (http://www.hacienda.go.cr/contenido/14350-factura-electronica)Note: This example requires Chilkat v9.5.0.75 or greater.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// This example will add an XAdES-EPES signature to the file
// at FacturaElectronica_cr.xml
//
// The XML to be signed looks like this:
