# 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::CkStringBuilder.new()
success = sbXml.LoadFile("qa_data/xml_dsig/sii_cl/signed1.xml","iso-8859-1")
if (success == false)
    print "Failed to load input file." + "\n";
    exit
end

dsig = Chilkat::CkXmlDSig.new()

success = dsig.LoadSignatureSb(sbXml)
if (success != true)
    print dsig.lastErrorText() + "\n";
    exit
end

bVerifyReferenceDigests = true
bVerified = dsig.VerifySignature(bVerifyReferenceDigests)
if (bVerified == false)
    print dsig.lastErrorText() + "\n";
    exit
end

print "Signature verified = " + bVerified.to_s() + "\n";
