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.

The signature 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)
