 * A generic interface for adding random bytes to an entropy pool.
00049 public interface EntropySource {

    * Returns the estimated quality of this source. This value should be
    * between 0 and 100 (the running quality is computed as a percentage,
    * 100 percent being perfect-quality).
    * @return The quality.
   double quality();

    * Returns a new buffer with the next random bytes to add.
    * @return The next random bytes.
