Method Detail
getId
- java.lang.String getId()
Returns:
the
Id attribute (may be null if
not specified) getValue
- byte[] getValue()
Returns the signature value of this
SignatureValue.
Returns:
the signature value (may be
null if the
XMLSignature has not been signed yet). Each
invocation of this method returns a new clone of the array to
prevent subsequent modification. validate
- boolean validate(XMLValidateContext validateContext)
- throws XMLSignatureException
Validates the signature value. This method performs a
cryptographic validation of the signature calculated over the
SignedInfo of the XMLSignature.
This method only validates the signature the first time it is invoked. On subsequent invocations, it returns a cached result.
Parameters:
validateContext - the validating context Returns:
true if the signature was
validated successfully; false otherwise Throws:
java.lang.NullPointerException - if validateContext is
null XMLSignatureException - if an unexpected exception occurs while
validating the signature
Idattribute of thisSignatureValue, which permits this element to be referenced from elsewhere.
