public Interface DigestMethod

extends XMLStructure, AlgorithmMethod
Known Direct Implementers
org.jcp.xml.dsig.internal.dom.DOMDigestMethod
Imports
javax.xml.crypto.AlgorithmMethod, .XMLStructure, javax.xml.crypto.dsig.spec.DigestMethodParameterSpec, java.security.spec.AlgorithmParameterSpec
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.

The digest method algorithm URIs defined in this class are specified in the W3C Recommendation for XML-Signature Syntax and Processing and RFC 9231: Additional XML Security Uniform Resource Identifiers (URIs)
