DSAKeyPairGenerator

An interface to an object capable of generating DSA key pairs.

The initialize methods may each be called any number of times. If no initialize method is called on a DSAKeyPairGenerator, the default is to generate 1024-bit keys, using precomputed p, q and g parameters and an instance of SecureRandom as the random bit source.

Users wishing to indicate DSA-specific parameters, and to generate a key pair suitable for use with the DSA algorithm typically

1. Get a key pair generator for the DSA algorithm by calling the KeyPairGenerator getInstance method with "DSA" as its argument.
2. Initialize the generator by casting the result to a DSAKeyPairGenerator and calling one of the initialize methods from this DSAKeyPairGenerator interface.
3. Generate a key pair by ca
