#define GNUTLS_PKCS11_MAX_PIN_LEN 32


gnutls_pkcs11_token_callback_t ()

int                 (*gnutls_pkcs11_token_callback_t)   (void *const userdata,
                                                         const char *const label,
                                                         unsigned  retry);

Token callback function. The callback will be used to ask the user to re-insert the token with given (null terminated) label. The callback should return zero if token has been inserted by user and a negative error code otherwise. It might be called multiple times if the token is not detected and the retry counter will be increased.

userdata :

user-controlled data from gnutls_pkcs11_set_token_function().

label :

token label.

retry :

retry counter, initially 0.

Returns :

GNUTLS_E_SUCCESS (0) on success or a negative error code on error.

Since 2.12.0

gnutls_pkcs11_init ()

int                 gnutls_pkcs11_init                  (unsigned int flags,

This function will initialize the PKCS 11 subsystem in gnutls. It will read configuration files if GNUTLS_PKCS11_FLAG_AUTO is used or allow you to independently load PKCS 11 modules using gnutls_pkcs11_add_provider() if GNUTLS_PKCS11_FLAG_MANUAL is specified.

Normally you don't need to call this function since it is being called by gnutls_global_init() using the GNUTLS_PKCS11_FLAG_AUTO. If other option is required then it must be called before it.

flags :

GNUTLS_PKCS11_FLAG_MANUAL or GNUTLS_PKCS11_FLAG_AUTO

deprecated_config_file :

either NULL or the location of a deprecated configuration file

Returns :

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

Since 2.12.0


gnutls_pkcs11_deinit ()

void                gnutls_pkcs11_deinit                (void);

                                                         void *userdata);

This function will set a callback function to be used when a token needs to be inserted to continue PKCS 11 operations.

fn :

The token callback

userdata :

data to be supplied to callback

Since 2.12.0


gnutls_pkcs11_set_pin_function ()

void                gnutls_pkcs11_set_pin_function      (gnutls_pin_callback_t fn,
                                                         void *userdata);

This function will set a callback function to be used when a PIN is required for PKCS 11 operations. See gnutls_pin_callback_t() on how the callback should behave.

fn :

The PIN callback, a gnutls_pin_callback_t() function.

userdata :

data to be supplied to callback

Since 2.12.0


gnutls_pkcs11_add_provider ()

int                 gnutls_pkcs11_add_provider          (const char *name,
                                                         const char *params);

This function will load and add a PKCS 11 module to the module list used in gnutls. After this function is called the module will be used for PKCS 11 operations.

name :

The filename of the module

params :

should be NULL

Returns :

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

Since 2.12.0


gnutls_pkcs11_obj_init ()

int                 gnutls_pkcs11_obj_init              (gnutls_pkcs11_obj_t *obj);

This function will initialize a pkcs11 certificate structure.

obj :

The structure to be initialized

Returns :

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

Since 2.12.0


GNUTLS_PKCS11_OBJ_FLAG_LOGIN

                                                         unsigned int flags);

This function will "import" a PKCS 11 URL identifying an object (e.g. certificate) to the gnutls_pkcs11_obj_t structure. This does not involve any parsing (such as X.509 or OpenPGP) since the gnutls_pkcs11_obj_t is format agnostic. Only data are transferred.

obj :

The structure to store the object

url :

a PKCS 11 url identifying the key

flags :

One of GNUTLS_PKCS11_OBJ_* flags

Returns :

This function will export the PKCS11 object data. It is normal for data to be inaccesible and in that case GNUTLS_E_INVALID_REQUEST will be returned.

If the buffer provided is not long enough to hold the output, then *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

If the structure is PEM encoded, it will have a header of "BEGIN CERTIFICATE".

obj :

Holds the object

output_data :

will contain a certificate PEM or DER encoded

output_data_size :

holds the size of output_data (and will be replaced by the actual size of parameters)

Returns :

In case of failure a negative error code will be returned, and GNUTLS_E_SUCCESS (0) on success.
