RAND_CLEANUP(3) OpenSSL RAND_CLEANUP(3)

RAND_cleanup - erase the PRNG state

#include <openssl/rand.h>

#if OPENSSL_API_COMPAT < 0x10100000L
void RAND_cleanup(void)
#endif

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() returns no value.

RAND(7)

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