       gnutls_pkcs12_mac_info - API function

       #include <gnutls/pkcs12.h>

       int gnutls_pkcs12_mac_info(gnutls_pkcs12_t pkcs12, unsigned int * mac,
       void * salt, unsigned int * salt_size, unsigned int * iter_count, char **

       gnutls_pkcs12_t pkcs12
                   A pkcs12 type

       unsigned int * mac
                   the MAC algorithm used as gnutls_mac_algorithm_t

       void * salt the salt used for string to key (if non-NULL then  salt_size
                   initially holds its size)

       unsigned int * salt_size
                   string to key salt size

       unsigned int * iter_count
                   string to key iteration count

       char ** oid if non-NULL it will contain an allocated null-terminated
                   variable with the OID

       This function will provide information on the MAC algorithm used in a
       PKCS 12 structure. If the structure algorithms are unknown the code
       GNUTLS_E_UNKNOWN_HASH_ALGORITHM will be returned, and only  oid , will be
       set. That is,  oid will be set on structures with a MAC whether supported
       or not. It must be deinitialized using gnutls_free().  The other
       variables are only set on supported structures.

       GNUTLS_E_INVALID_REQUEST if the provided structure doesn't contain a MAC,
       GNUTLS_E_UNKNOWN_HASH_ALGORITHM if the structure's MAC isn't supported,
       or another negative error code in case of a failure. Zero on success.
