Class KeyGeneratorSpi

This class defines the Service Provider Interface (SPI) for the KeyGenerator class. All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a key generator for a particular algorithm.

In case the client does not explicitly initialize the KeyGenerator (via a call to an init 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 KeyGenerator instead of relying on provider-specific defaults.
