gnutls_pkcs12_mac_info3

Usage

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

Overview

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.
