EncryptedKey Class

Note: This class is new in the .NET Framework version 2.0.

Represents the <EncryptedKey> element in XML encryption. This class cannot be inherited.

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

public ref class EncryptedKey sealed : public EncryptedType
public final class EncryptedKey extends EncryptedType
public final class EncryptedKey extends EncryptedType

This class represents the <EncryptedKey> element in XML encryption. The <EncryptedKey> element is used to send encryption keys. It can be created in a stand-alone XML document, be placed within an application document, or be inside an <EncryptedData> element as a child of a <KeyInfo> element. The key value is always encrypted to the recipient. When <EncryptedKey> is decrypted, the resulting key is made available to the <EncryptionMethod> algorithm without any additional processing.

The <EncryptedKey> element is similar to the <EncryptedData> element of the EncryptedData class except that the data encrypted is always a key value.

The following code example illustrates how to encrypt and decrypt an XML element using the EncryptedKey class. This example then displays the values of various properties of the EncryptedKey class to the console.

No code example is currently available or this language may not be supported.
