java.lang.Object | +--java.security.AlgorithmParameterGeneratorSpi
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.
