The Random number generator (RNG) module provides random number generation, see 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 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.

This module can be used to generate random numbers.
