  - ### Method Detail

    - #### init

          public void init(int size,
                           int certainty,
                           java.security.SecureRandom random)

      Initialise the parameters generator.
      Parameters:
        `size` - bit length for the prime p
        `certainty` - level of certainty for the prime number tests
        `random` - a source of randomness

    - #### generateParameters

          public DHParameters generateParameters()

      which generates the p and g values from the given parameters, returning the DHParameters object.
