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.
