' A sample XML file containing multiple signatures is available at:

' 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

' 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...
i = 0
Do While i < verifier.NumSignatures
' The Selector property is used to set our context to the Nth signature.
' For example, if VerifySignature is called when Selector = 0, then the 1st signature is verified.
' If VerifySignature is called when Selector = 1, then the 2nd signature is verified, and so on.
verifier.Selector = i
verifyReferenceDigests = 1
' The quick way to validate all references and the signature over the SignedInfo
' is to call VerifySignature with verifyReferenceDigests equal to 1.
verified = verifier.VerifySignature(verifyReferenceDigests)
Response.Write "<pre>" & Server.HTMLEncode( "Signature " & i + 1 & " and all reference digests verified = " & verified) & "</pre>"
' We can also get information about each signature.
' For example, we could get information about each Reference...
' The NumReferences property returns the number of references for the Signature indicated by the Selector property.
numReferences = verifier.NumReferences
Response.Write "<pre>" & Server.HTMLEncode( " number of references: " & numReferences) & "</pre>"
j = 0
Do While j < numReferences
' Get information about the Jth reference in the Ith signature.
Response.Write "<pre>" & Server.HTMLEncode( " reference " & j & ":") & "</pre>"
' Is this a same-document or external reference?
Response.Write "<pre>" & Server.HTMLEncode( " is external: " & verifier.IsReferenceExternal(j)) & "</pre>"
' For external references, the URI could be used by an application to fetch the referenced data...
Response.Write "<pre>" & Server.HTMLEncode( " uri: " & verifier.ReferenceUri(j)) & "</pre>"
j = j + 1
Loop
' We could also get the KeyInfo for each Signature, which might be needed if we need to
' load and set a public key that is not physically present within the KeyInfo already.
' keyInfoXml is a Chilkat.Xml
Set keyInfoXml = verifier.GetKeyInfo()
