EncryptedReference Class

.NET Framework (current version)

Represents the abstract base class used in XML encryption from which the CipherReference, KeyReference, and DataReference classes derive.

Namespace: System.Security.Cryptography.Xml
Assembly: System.Security (in System.Security.dll)

Inheritance Hierarchy

System::Object
System.Security.Cryptography.Xml::EncryptedReference
System.Security.Cryptography.Xml::CipherReference
System.Security.Cryptography.Xml::DataReference
System.Security.Cryptography.Xml::KeyReference

Syntax

C++

[HostProtectionAttribute(SecurityAction::LinkDemand, MayLeakOnAbort = true)]
public ref class EncryptedReference abstract

Constructors

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

Properties

	Name	Description
	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

	Name	Description
	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.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	GetXml()	Returns the XML representation of an EncryptedReference object.
	LoadXml(XmlElement^)	Loads an XML element into an EncryptedReference object.
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Examples

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

C++

#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 );
}
