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.
