A representation of the XML KeyInfo element as defined in the W3C Recommendation for XML-Signature Syntax and Processing.

  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.
