/**
|
|
* @addtogroup rng_module Random number generator (RNG) module
|
|
*
|
|
* 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 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.
|
|
*
|
|
* This module can be used to generate random numbers.
