- - ### Constructor Detail

    - #### KeyGenerationParameters

          public KeyGenerationParameters​(java.security.SecureRandom random,
                                         int strength)

      initialise the generator with a source of randomness and a strength (in bits).
      Parameters:
        `random` - the random byte source.
        `strength` - the size, in bits, of the keys we want to produce.

  - ### Method Detail

    - #### getRandom

          public java.security.SecureRandom getRandom()

      return the random source associated with this generator.
      Returns:
        the generators random source.

    - #### getStrength

          public int getStrength()

      return the bit strength for keys produced by this generator,
      Returns:
        the strength of the keys this generator produces (in bits).
