- * @addtogroup rng_module Random number generator (RNG) module
- *
- * The Random number generator (RNG) module provides random number
- * generation, see \c mbedtls_ctr_drbg_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 mbedtls_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.
