abstract public class: AlgorithmParameterGeneratorSpi [javadoc | source]

java.lang.Object
   java.security.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. For example, the Sun provider uses a default modulus prime size of 1024 bits for the generation of DSA parameters.
