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.
