| * |
| * 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 |
| * 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. |
| * |
| * \* 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. |
| * |
| * This module can be used to generate random numbers. |
