(PowerBuilder) Verify Multiple Signatures in XML

Demonstrates how to verify multiple signatures within a single XML document.

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

// A sample XML file containing multiple signatures is available at:
// https://www.chilkatsoft.com/exampleData/document.signed.bes.cs.xml

loo_Http = create oleobject
// Use "Chilkat_9_5_0.Http" for versions of Chilkat < 10.0.0
li_rc = loo_Http.ConnectToNewObject("Chilkat.Http")
if li_rc < 0 then
    destroy loo_Http
    MessageBox("Error","Connecting to COM object failed")
    return
end if
loo_SbXml = create oleobject
// Use "Chilkat_9_5_0.StringBuilder" for versions of Chilkat < 10.0.0
li_rc = loo_SbXml.ConnectToNewObject("Chilkat.StringBuilder")

li_Success = loo_Http.QuickGetSb("https://www.chilkatsoft.com/exampleData/document.signed.bes.cs.xml",loo_SbXml)
if li_Success <> 1 then
    Write-Debug loo_Http.LastErrorText
    destroy loo_Http
    destroy loo_SbXml
    return
end if

// Load the XML containing the signature to be verified.
loo_Verifier = create oleobject
// Use "Chilkat_9_5_0.XmlDSig" for versions of Chilkat < 10.0.0
li_rc = loo_Verifier.ConnectToNewObject("Chilkat.XmlDSig")

li_Success = loo_Verifier.LoadSignatureSb(loo_SbXml)
if li_Success <> 1 then
    Write-Debug loo_Verifier.LastErrorText
    destroy loo_Http
    destroy loo_SbXml
    destroy loo_Verifier
    return
end if

// How many Signatures exist in this XML?
Write-Debug "Number of XML signatures = " + string(loo_Verifier.NumSignatures)

// Let's show the XML nicely indented, so we can make sense of it.
// Loading the XML into an XML parser and re-emitting with nice formatting
// changes whitespace that breaks the signatures.  We're only doing this
// for the example to examine this XML, which contains 2 ds:Signature's
// and each signature has multiple references.

// This is what we have:

// When I look at the complicated XML above, there are specific things I look at to get a handle
// on the situation.
// 
// 1) Does the signature already embed the public keys required for verification?  
//    Within each <ds:Signature>, look for the <ds:KeyInfo>.  In this case, I can see that
//    each signature contains the full X.509 certificate needed to verify (<ds:KeyInfo><ds:X509Data><ds:X509Certificate>).
//    This means that Chilkat will automatically use the public keys contained within the base64 certificates
//    already present in the signature. 
// 
//  2) Look at each <ds:Reference> within each <ds:Signature>.  Do the URI attribute values begin with "#"?
//     If so, then these are same-document references, and there's no need to explicitly fetch external data for reference verification.
//     Chilkat can automatically validate each same-document Reference.
// 
// So it turns out that this seemingly formidable XML document is easy to verify...
// Here we go...
