- * The Random number generator (RNG) module provides random number
- * generation, see \c ctr_dbrg_random() or \c havege_random().

- * The former uses the block-cipher counter-mode based deterministic random
+ * The Random number generator (RNG) module provides random number
+ * generation, see \c ctr_dbrg_random().
+ *
+ * The block-cipher counter-mode based deterministic random
  * bit generator (CTR_DBRG) as specified in NIST SP800-90. It needs an external
  * source of entropy. For these purposes \c entropy_func() can be used. This is
  * an implementation based on a simple entropy accumulator design.
  *
- * The latter random number generator uses the HAVEGE (HArdware Volatile
- * Entropy Gathering and Expansion) software heuristic which is claimed 
- * to be an unpredictable or empirically strong* random number generation.
+ * The other number generator that is included is less strong and uses the HAVEGE
+ * (HArdware Volatile Entropy Gathering and Expansion) software heuristic
+ * which considered unsafe for primary usage, but provides additional random
+ * to the entropy pool if enables.
  *
  * \* Meaning that there seems to be no practical algorithm that can guess
  * the next bit with a probability larger than 1/2 in an output sequence.
