Overview

Since MariaDB 10.4 (released ~5 years ago) introduced an authentication method called auth_ed25519 and still supported till now in the latest versions of MariaDB which is now 11.3, here's official to read more about auth_ed25519

	mysqlnd_plugin_register_ex((struct st_mysqlnd_plugin_header *) &mysqlnd_pam_authentication_plugin);
#ifdef MYSQLND_HAVE_SSL
	mysqlnd_plugin_register_ex((struct st_mysqlnd_plugin_header *) &mysqlnd_caching_sha2_auth_plugin);
	mysqlnd_plugin_register_ex((struct st_mysqlnd_plugin_header *) &mysqlnd_sha256_authentication_plugin);
#endif
}
/* }}} */
