Examples

The following example uses the GetXml method in the CipherReference class to write the XML values to the console.

#using <System.Xml.dll>
#using <System.Security.dll>
#using <System.dll>

using namespace System;
using namespace System::Security::Cryptography::Xml;
using namespace System::Xml;
using namespace System::IO;

/// This sample used the GetXml method in the CipherReference class to 
/// write the XML values for the CipherReference to the console.

[STAThread]
int main()
{
   
   //Create a URI string.
   String^ uri = "http://www.woodgrovebank.com/document.xml";
   
   // Create a Base64 transform. The input content retrieved from the
   // URI should be Base64-decoded before other processing.
   Transform^ base64 = gcnew XmlDsigBase64Transform;
   
   //Create a transform chain and add the transform to it.
   TransformChain^ tc = gcnew TransformChain;
   tc->Add( base64 );
   
   //Create <CipherReference> information.
   CipherReference ^ reference = gcnew CipherReference( uri,tc );
   
   // Write the CipherReference value to the console.
   Console::WriteLine( "Cipher Reference data: {0}", reference->GetXml()->OuterXml );
}

{
    class CipherReference2
    {
        [STAThread]
        static void Main(string[] args)

            Transform base64 = new XmlDsigBase64Transform();

            //Create a transform chain and add the transform to it.
            TransformChain tc = new TransformChain();

            tc.Add(base64);

            //Create <CipherReference> information.
            CipherReference reference = new CipherReference(uri, tc);

Constructors

EncryptedReference()	Initializes a new instance of the EncryptedReference class.
EncryptedReference(String, TransformChain)	Initializes a new instance of the EncryptedReference class using the specified Uniform Resource Identifier (URI) and transform chain.
EncryptedReference(String)	Initializes a new instance of the EncryptedReference class using the specified Uniform Resource Identifier (URI).

Properties

CacheValid	Gets a value that indicates whether the cache is valid.
ReferenceType	Gets or sets a reference type.
TransformChain	Gets or sets the transform chain of an EncryptedReference object.
Uri	Gets or sets the Uniform Resource Identifier (URI) of an EncryptedReference object.

Methods

AddTransform(Transform)	Adds a Transform object to the current transform chain of an EncryptedReference object.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
