DESCRIPTION
These functions loop over all the ENGINE objects contained in the global table described in the ENGINE_add(3) manual page. They register each object for the respective algorithm by calling the corresponding function described in ENGINE_register_RSA(3).ENGINE_register_all_complete()
calls
ENGINE_register_complete()
in this way, except that it skips those ENGINE objects
that have the ENGINE_FLAGS_NO_REGISTER_ALL flag set
with
ENGINE_set_flags(3).
ENGINE_load_builtin_engines()
calls
OPENSSL_init_crypto(3) with no options, loads any built-in
engines that are enabled by default, and calls
ENGINE_register_all_complete(). Currently, LibreSSL
does not provide any engines.
GOST and
aesni
support is provided by the crypto library itself and does not require any
engines, not even built-in ones.
ENGINE_load_dynamic()
has no effect and is only provided for compatibility.
