             * An interface to an object capable of generating DSA key pairs.
             * <p>The {@code initialize} methods may each be called any number
             * of times. If no {@code 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.
             * <p>Users wishing to indicate DSA-specific parameters, and to generate a key
             * pair suitable for use with the DSA algorithm typically
             * <ol>
             * <li>Get a key pair generator for the DSA algorithm by calling the
             * KeyPairGenerator {@code getInstance} method with "DSA"
             * as its argument.
             * <li>Initialize the generator by casting the result to a DSAKeyPairGenerator
             * and calling one of the
             * {@code initialize} methods from this DSAKeyPairGenerator interface.
             * <li>Generate a key pair by calling the {@code generateKeyPair}
             * method from the KeyPairGenerator class.
             * </ol>
             * <p>Note: it is not always necessary to do do algorithm-specific
             * initialization for a DSA key pair generator. That is, it is not always
             * necessary to call an {@code initialize} method in this interface.
             * Algorithm-independent initialization using the {@code initialize} method
             * in the KeyPairGenerator
             * interface is all that is needed when you accept defaults for algorithm-specific
             * parameters.
             * <p>Note: Some earlier implementations of this interface may not support
             * larger sizes of DSA parameters such as 2048 and 3072-bit.
