AlgorithmParametersSpi

public abstract class AlgorithmParametersSpi extends Object

This class defines the Service Provider Interface (SPI) for the AlgorithmParameters class, which is used to manage algorithm parameters.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply parameter management for a particular algorithm.
