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 sup-
ported 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 sup-
ported, or another negative error code in case of a failure. Zero on
success.
