Method Detail

init

public void init(TransformParameterSpec params)
          throws java.security.InvalidAlgorithmParameterException

Description copied from class: TransformService

Initializes this TransformService with the specified parameters.

If the parameters exist in XML form, the TransformService.init(XMLStructure, XMLCryptoContext) method should be used to initialize the TransformService.

Specified by:

init in class TransformService

Parameters:

params - the algorithm parameters (may be null if not required or optional)

Throws:

java.security.InvalidAlgorithmParameterException - if the specified parameters are invalid for this algorithm

transform

public Data transform(Data data,
                      XMLCryptoContext xc)
               throws TransformException

Description copied from interface: Transform

Transforms the specified data using the underlying transform algorithm.

Parameters:

data - the data to be transformed

xc - the XMLCryptoContext containing additional context (may be null if not applicable)

Returns:

the transformed data

Throws:

TransformException - if an error occurs while executing the transform
