NAME

6       gnutls_pkcs12_mac_info - API function
7

SYNOPSIS

9       #include <gnutls/pkcs12.h>
10
11       int  gnutls_pkcs12_mac_info(gnutls_pkcs12_t pkcs12, unsigned int * mac,
12       void * salt, unsigned int * salt_size, unsigned int * iter_count,  char
13       ** oid);
14

ARGUMENTS

16       gnutls_pkcs12_t pkcs12
17                   A pkcs12 type
18
19       unsigned int * mac
20                   the MAC algorithm used as gnutls_mac_algorithm_t
21
22       void * salt the   salt  used  for  string  to  key  (if  non-NULL  then
23                   salt_size initially holds its size)
24
25       unsigned int * salt_size
26                   string to key salt size
27
28       unsigned int * iter_count
29                   string to key iteration count
30
31       char ** oid if non-NULL it will contain  an  allocated  null-terminated
32                   variable with the OID
33

DESCRIPTION

35       This  function  will provide information on the MAC algorithm used in a
36       PKCS 12 structure. If the structure algorithms  are  unknown  the  code
37       GNUTLS_E_UNKNOWN_HASH_ALGORITHM  will be returned, and only  oid , will
38       be set. That is,  oid will be set on structures with a MAC whether sup‐
39       ported or not. It must be deinitialized using gnutls_free().  The other
40       variables are only set on supported structures.
41

RETURNS

43       GNUTLS_E_INVALID_REQUEST if the provided structure  doesn't  contain  a
44       MAC,  GNUTLS_E_UNKNOWN_HASH_ALGORITHM if the structure's MAC isn't sup‐
45       ported, or another negative error code in case of a  failure.  Zero  on
46       success.
