gnutls_pkcs12_mac_info(3) 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 ** oid);


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.
