# NAME

RAND_cleanup - erase the PRNG state

# SYNOPSIS

     #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);

# 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)
