NAME
       RAND - pseudo-random number generator

SYNOPSIS
	#include <openssl/rand.h>

	int  RAND_bytes(unsigned char *buf, int num);
	int  RAND_pseudo_bytes(unsigned char *buf, int num);

DESCRIPTION
       These functions give access to the systems cryptographically secure
       pseudo-random number generator (PRNG). It is used by other library
       functions for example to generate random keys, and applications can use
       it when they need randomness.

       RAND_bytes(3) describes how to obtain random data from the PRNG.

INTERNALS
       The RAND_SSLeay() method implements a PRNG based on the systems'
       arc4random_buf(3) random number generator.
