NAME
RAND - pseudo-random number generatorSYNOPSIS
#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.INTERNALS
The RAND_SSLeay() method implements a PRNG based on the systems' arc4random_buf(3) random number generator.SEE ALSO
