Interface SignedInfo

All Superinterfaces:: XMLStructure

public interface SignedInfo
extends XMLStructure
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.

Since:: 1.6
See Also:: XMLSignatureFactory.newSignedInfo(CanonicalizationMethod, SignatureMethod, List), XMLSignatureFactory.newSignedInfo(CanonicalizationMethod, SignatureMethod, List, String)

Method Detail

getCanonicalizationMethod

CanonicalizationMethod getCanonicalizationMethod()

Returns the canonicalization method of this SignedInfo.

Returns:: the canonicalization method

getSignatureMethod

SignatureMethod getSignatureMethod()

Returns the signature method of this SignedInfo.

Returns:: the signature method

getReferences

List getReferences()

Returns an unmodifiable list of one or more References.

Returns:: an unmodifiable list of one or more References

getId

String getId()

Returns the optional Id attribute of this SignedInfo.

Returns:: the id (may be null if not specified)

getCanonicalizedData
