Interface SignedInfo

All Superinterfaces:

XMLStructure

public interface SignedInfo

extends XMLStructure

An representation of the XML SignedInfo element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. The XML Schema Definition is defined as:

 <element name="SignedInfo" type="ds:SignedInfoType"/> 
 <complexType name="SignedInfoType">
   <sequence> 
     <element ref="ds:CanonicalizationMethod"/> 
     <element ref="ds:SignatureMethod"/> 
     <element ref="ds:Reference" maxOccurs="unbounded"/> 
   </sequence>  
   <attribute name="Id" type="ID" use="optional"/> 
 </complexType>
 

A SignedInfo instance may be created by invoking one of the newSignedInfo methods of the XMLSignatureFactory class.

the canonicalization method

getSignatureMethod

public SignatureMethod getSignatureMethod()

Returns the signature method of this SignedInfo.

Returns:

the signature method

getReferences

public java.util.List getReferences()

Returns an unmodifiable list of one or more References.

Returns:
