RAND_set_rand_method(3)

NAME

RAND_set_rand_method, RAND_get_rand_method, RAND_SSLeay — select RAND method

/* -lcrypto */
#include <openssl/rand.h>

int
RAND_set_rand_method(const RAND_METHOD *meth);

const RAND_METHOD *
RAND_get_rand_method(void);

RAND_METHOD *
RAND_SSLeay(void);

These functions used to allow for the random number generator functions to be replaced by arbitrary code.

They are kept for ABI compatibility but are no longer functional, and should not be used in new programs.

RAND_set_rand_method() always returns 1. RAND_get_rand_method() and RAND_SSLeay() always return NULL.

RAND_set_rand_method(), RAND_get_rand_method(), and RAND_SSLeay() first appeared in SSLeay 0.9.1 and have been available since OpenBSD 2.6.
