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.

XMLSignatureFactory.newDigestMethod(String, DigestMethodParameterSpec)
Field Summary |
static java.lang.String |
SHA1
The
SHA1 digest method algorithm URI. |
Method Summary |
java.security.spec.AlgorithmParameterSpec |
getParameterSpec()
Returns the algorithm-specific input parameters associated with this
DigestMethod . |
SHA1
public static final java.lang.String SHA1
- The
SHA1 digest method algorithm URI.

- Constant Field Values
getParameterSpec
public java.security.spec.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)
