(C++) Paraguay E-Invoicing Signed XML (SIFEN)See more XML Digital Signatures ExamplesDemonstrates how to sign XML for e-invoicing -- SISTEMA INTEGRADO DE FACTURACIÓN ELECTRÓNICA NACIONAL (SIFEN). This is for signing XML files that need to be submitted to a government agency (Country Paraguay, SIFEN / EKUATIA, Sistema Nacional de Facturacion Electrónica).
