Interface DigestMethod

All Superinterfaces:
AlgorithmMethod, XMLStructure

  1. public interface DigestMethod
  2. 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.

XMLSignatureFactory.newDigestMethod(String, DigestMethodParameterSpec)
