示例1: SignDetachedResource
' Sign an XML file and save the signature in a new file.
Public Shared Sub SignDetachedResource(URIString As String, XmlSigFileName As String, DSAKey As DSA)
' Create a SignedXml object.
Dim signedXml As New SignedXml()
' Assign the DSA key to the SignedXml object.
signedXml.SigningKey = DSAKey
' Create a reference to be signed.
Dim reference As New Reference()
' Add the passed URI to the reference object.
reference.Uri = URIString
' Add the reference to the SignedXml object.
signedXml.AddReference(reference)
' Add a DSAKeyValue to the KeyInfo (optional; helps recipient find key to validate).
Dim keyInfo As New KeyInfo()
keyInfo.AddClause(New DSAKeyValue(CType(DSAKey, DSA)))
signedXml.KeyInfo = keyInfo
' Compute the signature.
signedXml.ComputeSignature()
' Get the XML representation of the signature and save
' it to an XmlElement object.
Dim xmlDigitalSignature As XmlElement = signedXml.GetXml()
' Save the signed XML document to a file specified
' using the passed string.
Dim xmltw As New XmlTextWriter(XmlSigFileName, New UTF8Encoding(False))
xmlDigitalSignature.WriteTo(xmltw)
xmltw.Close()
End Sub示例2: SignXmlFile
' Sign an XML file and save the signature in a new file.
Public Shared Sub SignXmlFile(FileName As String, SignedFileName As String, DSAKey As DSA)
' Create a new XML document.
Dim doc As New XmlDocument()
' Format the document to ignore white spaces.
doc.PreserveWhitespace = False
' Load the passed XML file using it's name.
doc.Load(New XmlTextReader(FileName))
' Create a SignedXml object.
Dim signedXml As New SignedXml(doc)
' Add the DSA key to the SignedXml document.
signedXml.SigningKey = DSAKey
' Create a reference to be signed.
Dim reference As New Reference()
reference.Uri = ""
' Add a transformation to the reference.
Dim trns = New XmlDsigC14NTransform()
reference.AddTransform(trns)
' Add an enveloped transformation to the reference.
Dim env As New XmlDsigEnvelopedSignatureTransform()
reference.AddTransform(env)
' Add the reference to the SignedXml object.
signedXml.AddReference(reference)
' Add a DSAKeyValue to the KeyInfo (optional; helps recipient find key to validate).
Dim keyInfo As New KeyInfo()
keyInfo.AddClause(New DSAKeyValue(CType(DSAKey, DSA)))
signedXml.KeyInfo = keyInfo
' Compute the signature.
signedXml.ComputeSignature()
' Get the XML representation of the signature and save
' it to an XmlElement object.
Dim xmlDigitalSignature As XmlElement = signedXml.GetXml()
' Append the element to the XML document.
doc.DocumentElement.AppendChild(doc.ImportNode(xmlDigitalSignature, True))
If TypeOf doc.FirstChild Is XmlDeclaration Then
doc.RemoveChild(doc.FirstChild)
End If
' Save the signed XML document to a file specified
' using the passed string.
Dim xmltw As New XmlTextWriter(SignedFileName, New UTF8Encoding(False))
