package com.sun.org.apache.xml.internal.security.encryption;


The EncryptedKey element is used to transport encryption keys
from the originator to a known recipient(s). It may be used as a stand-alone
XML document, be placed within an application document, or appear inside an
EncryptedData element as a child of a ds:KeyInfo
element. The key value is always encrypted to the recipient(s). When
EncryptedKey is decrypted the resulting octets are made
available to the EncryptionMethod algorithm without any
additional processing.


Its schema definition is as follows:


<element name='EncryptedKey' type='xenc:EncryptedKeyType'/>
<complexType name='EncryptedKeyType'>
    <complexContent>
        <extension base='xenc:EncryptedType'>
            <sequence>
                <element ref='xenc:ReferenceList' minOccurs='0'/>
                <element name='CarriedKeyName' type='string' minOccurs='0'/>
            </sequence>
            <attribute name='Recipient' type='string' use='optional'/>
        </extension>
    </complexContent>

public interface EncryptedKey extends EncryptedType {

    
Returns a hint as to which recipient this encrypted key value is intended for.

Sets the recipient for this EncryptedKey.

Returns pointers to data and keys encrypted using this key. The reference
list may contain multiple references to EncryptedKey and
EncryptedData elements. This is done using
KeyReference and DataReference elements
respectively.

Returns:an Iterator over all the ReferenceLists
  contained in this EncryptedKey.

Returns a user readable name with the key value. This may then be used to
reference the key using the ds:KeyName element within
ds:KeyInfo. The same CarriedKeyName label,
unlike an ID type, may occur multiple times within a single document. The
value of the key is to be the same in all EncryptedKey
elements identified with the same CarriedKeyName label
within a single XML document.


Note that because whitespace is significant in the value of
the ds:KeyName element, whitespace is also significant in
the value of the CarriedKeyName element.

Returns:over all the carried names contained in
  this EncryptedKey.
