NAME

OPENSSL_load_builtin_modules, ASN1_add_oid_module — add standard configuration modules

SYNOPSIS

#include <openssl/conf.h>

void
OPENSSL_load_builtin_modules(void);

void
ASN1_add_oid_module(void);

DESCRIPTION

The function OPENSSL_load_builtin_modules() adds all the standard OpenSSL configuration modules to the internal list. They can then be used by the OpenSSL configuration code.

ASN1_add_oid_module() adds just the ASN.1 OBJECT module.

If the simple configuration function OPENSSL_config(3) is called then OPENSSL_load_builtin_modules() is called automatically.

Applications which use configuration functions like CONF_modules_load_file(3) directly need to call OPENSSL_load_builtin_modules() themselves before any other configuration code.

Applications should call OPENSSL_config(3) or OPENSSL_load_builtin_modules() to load all configuration modules instead of adding modules selectively: otherwise functionality may be missing from the application when new modules are added.

HISTORY

These functions first appeared in OpenSSL 0.9.7 and have been available since OpenBSD 3.2.
