public interface KeyInfo
extends XMLStructure

A representation of the XML KeyInfo element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. A KeyInfo contains a list of XMLStructures, each of which contain information that enables the recipient(s) to obtain the key needed to validate an XML signature. The XML Schema Definition is defined as:

<element name="KeyInfo" type="ds:KeyInfoType"/>
 <complexType name="KeyInfoType" mixed="true">
   <choice maxOccurs="unbounded">
     <element ref="ds:KeyName"/>
     <element ref="ds:KeyValue"/>
     <element ref="ds:RetrievalMethod"/>
     <element ref="ds:X509Data"/>
     <element ref="ds:PGPData"/>
     <element ref="ds:SPKIData"/>
     <element ref="ds:MgmtData"/>
     <any processContents="lax" namespace="##other"/>
     <!-- (1,1) elements from (0,unbounded) namespaces -->
   </choice>
   <attribute name="Id" type="ID" use="optional"/>
 </complexType>

A KeyInfo instance may be created by invoking one of the newKeyInfo methods of the KeyInfoFactory class, and passing it a list of one or more XMLStructures and an optional id parameter; for example:

KeyInfoFactory factory = KeyInfoFactory.getInstance("DOM");
   KeyInfo keyInfo = factory.newKeyInfo
      (Collections.singletonList(factory.newKeyName("Alice"), "keyinfo-1"));

KeyInfo objects can also be marshalled to XML by invoking the marshal method.

List getContent()

Returns an unmodifiable list containing the key information. Each entry of the list is an XMLStructure.

If there is a public subclass representing the type of XMLStructure, it is returned as an instance of that class (ex: an X509Data element would be returned as an instance of X509Data).

String getId()

void marshal(XMLStructure parent,
             XMLCryptoContext context)
      throws MarshalException
