DOMSignatureMethod JDK 1.6)

Constructors

protected DOMSignatureMethod (Element smElem) throws MarshalException

Creates a DOMSignatureMethod from an element.

Creates a DOMSignatureMethod from an element. This ctor
invokes the abstract unmarshalParams method to
unmarshal any algorithm-specific input parameters.
Parameters:
- smElem - a SignatureMethod element

protected DOMSignatureMethod (String algorithm, AlgorithmParameterSpec params) throws InvalidAlgorithmParameterException

Creates a DOMSignatureMethod.

Creates a DOMSignatureMethod.
Parameters:
- algorithm - the URI identifying the signature algorithm
- params - the algorithm-specific params (may be null)
Throws:
- NullPointerException - if algorithm is null
- InvalidAlgorithmParameterException - if the parameters are not appropriate for this signature method

Methods

Hide/Show inherited methods

protectedabstract void checkParams (SignatureMethodParameterSpec params) throws InvalidAlgorithmParameterException

Checks if the specified parameters are valid for this algorithm.

Checks if the specified parameters are valid for this algorithm.
Parameters:
- params - the algorithm-specific params (may be null)
Throws:
- InvalidAlgorithmParameterException - if the parameters are not appropriate for this signature method

public boolean equals (Object o)

publicfinal String getAlgorithm ()

publicfinal AlgorithmParameterSpec getParameterSpec () [Specified in SignatureMethod]

publicfinal boolean isFeatureSupported (String feature) [Inherited From DOMStructure]

public void marshal (Node parent, String dsPrefix, DOMCryptoContext context) throws MarshalException [Specified in DOMStructure]

This method invokes the abstract marshalParams method to marshal any algorithm-specific parameters.

protectedabstract void marshalParams (Element parent, String paramsPrefix) throws MarshalException

Marshals the algorithm-specific parameters to an Element and appends it to the specified parent element.

protectedabstract boolean paramsEqual (AlgorithmParameterSpec spec)

Returns true if parameters are equal; false otherwise.

publicabstract byte sign (Key key, DOMSignedInfo si, XMLSignContext context) throws InvalidKeyException XMLSignatureException

Signs the bytes with the specified key, using the underlying signature or MAC algorithm.

Signs the bytes with the specified key, using the underlying
signature or MAC algorithm.
Returns: the signature
Parameters:
- key - the signing key
- si - the DOMSignedInfo
- context - the XMLSignContext
Throws:
- NullPointerException - if key or si are null
- InvalidKeyException - if the key is improperly encoded, of the wrong type, or parameters are missing, etc
- XMLSignatureException - if an unexpected error occurs

pack-privatestatic SignatureMethod unmarshal (Element smElem) throws MarshalException

protectedabstract SignatureMethodParameterSpec unmarshalParams (Element paramsElem) throws MarshalException

Unmarshals SignatureMethodParameterSpec from the specified Element.

Unmarshals SignatureMethodParameterSpec from the specified
Element. Subclasses should implement this to unmarshal
the algorithm-specific parameters.
Returns: the algorithm-specific SignatureMethodParameterSpec
Parameters:
- paramsElem - the Element holding the input params
Throws:
- MarshalException - if the parameters cannot be unmarshalled

publicabstract boolean verify (Key key, DOMSignedInfo si, byte[] signature, XMLValidateContext context) throws InvalidKeyException SignatureException XMLSignatureException

Verifies the passed-in signature with the specified key, using the underlying signature or MAC algorithm.

Verifies the passed-in signature with the specified key, using the
underlying signature or MAC algorithm.
Returns: true if the signature verified successfully, false if not
Parameters:
- key - the verification key
- si - the DOMSignedInfo
- signature - the signature bytes to be verified
- context - the XMLValidateContext
Throws:
- NullPointerException - if key, si or signature are null
- InvalidKeyException - if the key is improperly encoded, of the wrong type, or parameters are missing, etc
- SignatureException - if an unexpected error occurs, such as the passed in signature is improperly encoded
- XMLSignatureException - if an unexpected error occurs
