NAME

       gnutls_pkcs12_mac_info - API function

SYNOPSIS

       #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 ** oid);

ARGUMENTS

       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

DESCRIPTION

       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.

RETURNS

       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.
