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.
 See the Keysize Restriction sections of the
 JDK Providers
 document for information on the AlgorithmParameterGenerator defaults
 used by JDK providers.
 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.
