    PHP 8 deprecates openssl_free_key (actually openssl_pkey_free which it aliases) and automatically destroys the key instance when it goes out of scope.

    This function also frees public key resources as received with openssl_pkey_get_public().

    Manual above should say: "Frees a pkey resource"
