Verify Factura Electronica Chile SII (iso-8859-1)

See more XAdES Examples

Demonstrates how to verify SII XML stored as iso-8859-1 having just a single signature. C#

bool success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The signed XML to be verified in this example contains the following:

// <?xml version="1.0" encoding="ISO-8859-1"?>
// <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
// <Documento ID="F13T34">
// ...
// </Documento>
// <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
// ....
// </Signature>
// </DTE>

// Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1 
Chilkat.StringBuilder sbXml = new Chilkat.StringBuilder();
success = sbXml.LoadFile("qa_data/xml_dsig/sii_cl/signed1.xml","iso-8859-1");
if (success == false) {
    Debug.WriteLine("Failed to load input file.");
    return;
}

Chilkat.XmlDSig dsig = new Chilkat.XmlDSig();

success = dsig.LoadSignatureSb(sbXml);
if (success != true) {
    Debug.WriteLine(dsig.LastErrorText);
    return;
}

bool bVerifyReferenceDigests = true;
bool bVerified = dsig.VerifySignature(bVerifyReferenceDigests);
if (bVerified == false) {
    Debug.WriteLine(dsig.LastErrorText);
    return;
}

Debug.WriteLine("Signature verified = " + Convert.ToString(bVerified));
