AlgorithmParameterGeneratorSpi

abstract class AlgorithmParameterGeneratorSpi

This class defines the Service Provider Interface (SPI) for the AlgorithmParameterGenerator class, which is used to generate a set of parameters to be used with a certain algorithm.

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

In case the client does not explicitly initialize the AlgorithmParameterGenerator (via a call to an engineInit method), each provider must supply (and document) a default initialization. However, note that defaults may vary across different providers. Additionally, the default value for a provider may change in a future version. Therefore, it is recommended to explicitly initialize the AlgorithmParameterGenerator instead of relying on provider-specific defaults.
