Interface SignatureMethod

All Superinterfaces:

AlgorithmMethod, XMLStructure

public interface SignatureMethod

extends XMLStructure, AlgorithmMethod

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

   <element name="SignatureMethod" type="ds:SignatureMethodType"/>
     <complexType name="SignatureMethodType" mixed="true">
       <sequence>
         <element name="HMACOutputLength" minOccurs="0" type="ds:HMACOutputLengthType"/>
         <any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
           <!-- (0,unbounded) elements from (1,1) namespace -->
       </sequence>
       <attribute name="Algorithm" type="anyURI" use="required"/>
     </complexType>
 

A SignatureMethod instance may be created by invoking the newSignatureMethod method of the XMLSignatureFactory class.

XMLSignatureFactory.newSignatureMethod(String, SignatureMethodParameterSpec)

Method Detail

getParameterSpec

public AlgorithmParameterSpec getParameterSpec()

Returns the algorithm-specific input parameters of this SignatureMethod.

The returned parameters can be typecast to a SignatureMethodParameterSpec object.

Specified by:

getParameterSpec in interface AlgorithmMethod

Returns:

the algorithm-specific input parameters of this SignatureMethod (may be null if not specified)
