Interface DigestMethod

All Superinterfaces:
AlgorithmMethod, XMLStructure

public interface DigestMethod
extends XMLStructure, AlgorithmMethod

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

   <element name="DigestMethod" type="ds:DigestMethodType"/>
     <complexType name="DigestMethodType" mixed="true">
       <sequence>
         <any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
           <!-- (0,unbounded) elements from (1,1) namespace -->
       </sequence>
       <attribute name="Algorithm" type="anyURI" use="required"/>
     </complexType>
 
A DigestMethod instance may be created by invoking the newDigestMethod method of the XMLSignatureFactory class.

Since:
1.6

Method Detail

getParameterSpec

AlgorithmParameterSpec getParameterSpec()
Returns the algorithm-specific input parameters associated with this DigestMethod.

The returned parameters can be typecast to a DigestMethodParameterSpec object.

Specified by:
getParameterSpec in interface AlgorithmMethod
Returns:
the algorithm-specific parameters (may be null if not specified)
