       Prior to OpenSSL 1.1.0, RAND_cleanup() released all resources used by the PRNG.  As of version 1.1.0, it
       does nothing and should not be called, since no explicit initialisation or de-initialisation is
       necessary. See OPENSSL_init_crypto(3).

RAND_cleanup() was deprecated in OpenSSL 1.1.0; do not use it.  See OPENSSL_init_crypto(3)

RAND_cleanup() returns no value.

RAND(7)

        #include <openssl/rand.h>

       The following function has been deprecated since OpenSSL 1.1.0, and can be hidden entirely by defining
       OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):

        void RAND_cleanup(void);
