DESCRIPTION

ENGINE objects used to provide alternative implementations of cryptographic algorithms, for example using specialized hardware. LibreSSL no longer supports this feature.

All functions in this manual ignore all their arguments and do nothing except return failure if possible. They are provided only to avoid patching software that expects ENGINE support to be available.

RETURN VALUES

ENGINE_new(), ENGINE_by_id(), ENGINE_get_default_RSA(), ENGINE_load_private_key(), and ENGINE_load_public_key() always return NULL.

ENGINE_free(), ENGINE_init(), ENGINE_finish(), ENGINE_ctrl_cmd(), ENGINE_ctrl_cmd_string(), ENGINE_set_default(), ENGINE_set_default_RSA(), and ENGINE_register_all_complete() always return 0.

ENGINE_get_id() and ENGINE_get_name() always return the constant empty string.

HISTORY

ENGINE_new(), ENGINE_free(), ENGINE_init(), ENGINE_finish(), ENGINE_by_id(), ENGINE_get_id(), ENGINE_get_name(), ENGINE_set_default(), ENGINE_get_default_RSA(), ENGINE_set_default_RSA(), ENGINE_load_private_key(), and ENGINE_load_public_key() first appeared in OpenSSL 0.9.7 and have been available since OpenBSD 2.9.

ENGINE_ctrl_cmd(), ENGINE_ctrl_cmd_string(), ENGINE_load_builtin_engines(), ENGINE_load_openssl(), ENGINE_register_all_complete(), and ENGINE_cleanup() first appeared in OpenSSL 0.9.7 and have been available since OpenBSD 3.4.

All these functions were turned into stubs in OpenBSD 7.4.
