markrad 58:f50b97b08851 26 * The Random number generator (RNG) module provides random number

markrad 58:f50b97b08851 30 * bit generator (CTR_DBRG) as specified in NIST SP800-90. It needs an external
markrad 58:f50b97b08851 31 * source of entropy. For these purposes \c mbedtls_entropy_func() can be used.
markrad 58:f50b97b08851 32 * This is an implementation based on a simple entropy accumulator design.
markrad 58:f50b97b08851 33 *
markrad 58:f50b97b08851 34 * The other number generator that is included is less strong and uses the
markrad 58:f50b97b08851 35 * HAVEGE (HArdware Volatile Entropy Gathering and Expansion) software heuristic
markrad 58:f50b97b08851 36 * which considered unsafe for primary usage, but provides additional random
markrad 58:f50b97b08851 37 * to the entropy pool if enables.
markrad 58:f50b97b08851 38 *
markrad 58:f50b97b08851 39 * Meaning that there seems to be no practical algorithm that can guess
markrad 58:f50b97b08851 40 * the next bit with a probability larger than 1/2 in an output sequence.

markrad 58:f50b97b08851 42 * This module can be used to generate random numbers.
