# NAME

RAND_cleanup - erase the PRNG state

# SYNOPSIS

     #include <openssl/rand.h>

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

# DESCRIPTION

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).

# RETURN VALUES

`RAND_cleanup()` returns no value.

# SEE ALSO

RAND(7)

# HISTORY

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