SYNOPSIS

#include <openssl/engine.h> void
ENGINE_register_all_RSA(void); void
ENGINE_register_all_DSA(void); void
ENGINE_register_all_ECDH(void); void
ENGINE_register_all_ECDSA(void); void
ENGINE_register_all_DH(void); void
ENGINE_register_all_RAND(void); void
ENGINE_register_all_STORE(void); void
ENGINE_register_all_ciphers(void); void
ENGINE_register_all_digests(void); int
ENGINE_register_all_complete(void); void
ENGINE_load_builtin_engines(void); void
ENGINE_load_dynamic(void);

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.
