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.

gnutls_pkcs11_init ()

int
gnutls_pkcs11_init (unsigned int flags,
                    const char *deprecated_config_file);

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.

You don't need to call this function since GnuTLS 3.3.0 because it is being called during the first request PKCS 11 operation. That call will assume the GNUTLS_PKCS11_FLAG_AUTO flag. If another flags are required then it must be called independently prior to any PKCS 11 operation.

Since: 2.12.0

gnutls_pkcs11_token_get_info ()

int
gnutls_pkcs11_token_get_info (const char *url,

                              size_t *output_size);

This function will return information about the PKCS 11 token such as the label, id, etc.

When output is text, a null terminated string is written to output and its string length is written to output_size (without null terminator). If the buffer is too small, output_size will contain the expected buffer size (with null terminator for text) and return GNUTLS_E_SHORT_MEMORY_BUFFER.

This function will initialize and set values to an object list by using all objects identified by a PKCS 11 URL.

This function will enumerate all the objects specified by the PKCS11 URL provided. It expects an already allocated p_list which has *n_list elements, and that value will be updated to the actual number of present objects. The p_list objects will be initialized and set by this function. To obtain a list of all available objects use a url of 'pkcs11:'.

All returned objects must be deinitialized using gnutls_pkcs11_obj_deinit().

The supported in this function flags are GNUTLS_PKCS11_OBJ_FLAG_LOGIN, GNUTLS_PKCS11_OBJ_FLAG_LOGIN_SO, GNUTLS_PKCS11_OBJ_FLAG_PRESENT_IN_TRUSTED_MODULE, GNUTLS_PKCS11_OBJ_FLAG_CRT, GNUTLS_PKCS11_OBJ_FLAG_PUBKEY, GNUTLS_PKCS11_OBJ_FLAG_PRIVKEY, GNUTLS_PKCS11_OBJ_FLAG_WITH_PRIVKEY, GNUTLS_PKCS11_OBJ_FLAG_MARK_CA, GNUTLS_PKCS11_OBJ_FLAG_MARK_TRUSTED, and since 3.5.1 the GNUTLS_PKCS11_OBJ_FLAG_OVERWRITE_TRUSTMOD_EXT.

In versions of GnuTLS later than 3.5.11 the object is protected using locks and a single gnutls_pkcs11_privkey_t can be re-used by many threads. However, for performance it is recommended to utilize one object per key per thread.

gnutls_pkcs11_privkey_cpy ()

int
gnutls_pkcs11_privkey_cpy (gnutls_pkcs11_privkey_t dst,

                                  unsigned int flags);

This function will "import" a PKCS 11 URL identifying a private key to the gnutls_pkcs11_privkey_t type. In reality since in most cases keys cannot be exported, the private key structure is being associated with the available operations on the token.

This function will generate a private key in the specified by the url token. The private key will be generate within the token and will not be exportable. This function will store the DER-encoded public key in the SubjectPublicKeyInfo format in pubkey . The pubkey should be deinitialized using gnutls_free().

Note that when generating an elliptic curve key, the curve can be substituted in the place of the bits parameter using the GNUTLS_CURVE_TO_BITS() macro.

Since 3.6.3 the objects are marked as sensitive by default unless GNUTLS_PKCS11_OBJ_FLAG_MARK_NOT_SENSITIVE is specified.

                                     unsigned int flags);

This function will extract the public key (modulus and public exponent) from the private key specified by the url private key. This public key will be stored in pubkey in the format specified by fmt . pubkey should be deinitialized using gnutls_free().
