XMLSignature JDK 1.6)

Description

public interface XMLSignature

A representation of the XML Signature element as defined in the W3C Recommendation for XML-Signature Syntax and Processing.

A representation of the XML Signature element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. This class contains methods for signing and validating XML signatures with behavior as defined by the W3C specification. The XML Schema Definition is defined as:


 <element name="Signature" type="ds:SignatureType"/>
 <complexType name="SignatureType">
    <sequence> 
      <element ref="ds:SignedInfo"/> 
      <element ref="ds:SignatureValue"/> 
      <element ref="ds:KeyInfo" minOccurs="0"/> 
      <element ref="ds:Object" minOccurs="0" maxOccurs="unbounded"/> 
    </sequence>  
    <attribute name="Id" type="ID" use="optional"/>
 </complexType>

An XMLSignature instance may be created by invoking one of the newXMLSignature methods of the XMLSignatureFactory class.

If the contents of the underlying document containing the XMLSignature are subsequently modified, the behavior is undefined.

Note that this class is named XMLSignature rather than Signature to avoid naming clashes with the existing java.security.Signature class.

Methods

Hide/Show inherited methods

public String getId ()

Returns the optional Id of this XMLSignature.

Returns the optional Id of this XMLSignature.
Returns: the Id (may be null if not specified)

public KeyInfo getKeyInfo ()

Returns the key info of this XMLSignature.

Returns the key info of this XMLSignature.
Returns: the key info (may be null if not specified)

public KeySelectorResult getKeySelectorResult ()

Returns the result of the KeySelector, if specified, after this XMLSignature has been signed or validated.

Returns the result of the KeySelector, if specified, after
this XMLSignature has been signed or validated.
Returns: the key selector result, or null if a key selector has not been specified or this XMLSignature has not been signed or validated

public List getObjects ()

Returns an

unmodifiable
 list

of XMLObjects contained in this XMLSignature.

Returns an

unmodifiable
 list

of XMLObjects contained in this XMLSignature.
Returns: an unmodifiable list of XMLObjects (may be empty but never null)

public SignatureValue getSignatureValue ()

Returns the signature value of this XMLSignature.

Returns the signature value of this XMLSignature.
Returns: the signature value

public SignedInfo getSignedInfo ()

Returns the signed info of this XMLSignature.

Returns the signed info of this XMLSignature.
Returns: the signed info (never null)

public void sign (XMLSignContext signContext) throws MarshalException XMLSignatureException

Signs this XMLSignature.

If this method throws an exception, this XMLSignature and the signContext parameter will be left in the state that it was in prior to the invocation.
Parameters:
- signContext - the signing context
Throws:
- ClassCastException - if the type of signContext is not compatible with this XMLSignature
- NullPointerException - if signContext is null
- MarshalException - if an exception occurs while marshalling
- XMLSignatureException - if an unexpected exception occurs while generating the signature

public boolean validate (XMLValidateContext validateContext) throws XMLSignatureException

Validates the signature according to the core validation processing rules.

Validates the signature according to the core validation processing rules. This method validates the signature using the existing state, it does not unmarshal and reinitialize the contents of the XMLSignature using the location information specified in the context.

This method only validates the signature the first time it is invoked. On subsequent invocations, it returns a cached result.
Returns: true if the signature passed core validation, otherwise false
Parameters:
- validateContext - the validating context
Throws:
- ClassCastException - if the type of validateContext is not compatible with this XMLSignature
- NullPointerException - if validateContext is null
- XMLSignatureException - if an unexpected error occurs during validation that prevented the validation operation from completing
