In fact, I'm working on a method which is similar to

  /*
   * Generates some random bytes.
   *
   * @param n requested random value in bytes.
   * @param extraEntropy optional entropy caller can provide, null if none.
   */
  byte[] getRandom(int n, byte[] extraEntropy)

Most caller won't be able to provide extra entropy, but if one does have a dedicated device which can generate fresh entropy, it is welcome.

Thanks
