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

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

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // 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 
    sbXml := chilkat.NewStringBuilder()
    success := sbXml.LoadFile("qa_data/xml_dsig/sii_cl/signed1.xml","iso-8859-1")
    if success == false {
        fmt.Println("Failed to load input file.")
        sbXml.DisposeStringBuilder()
        return
    }

    dsig := chilkat.NewXmlDSig()

    success = dsig.LoadSignatureSb(sbXml)
    if success != true {
        fmt.Println(dsig.LastErrorText())
        sbXml.DisposeStringBuilder()
        dsig.DisposeXmlDSig()
        return
    }

    bVerifyReferenceDigests := true
    bVerified := dsig.VerifySignature(bVerifyReferenceDigests)
    if bVerified == false {
        fmt.Println(dsig.LastErrorText())
        sbXml.DisposeStringBuilder()
