gnutls_x509_crt_get_key_purpose_oid(3) |
 |
gnutls_x509_crt_get_key_purpose_oid − This function returns the Certificate’s key purpose OIDs
#include <gnutls/x509.h>
int gnutls_x509_crt_get_key_purpose_oid(gnutls_x509_crt_t cert, int indx, void * oid, size_t * sizeof_oid, unsigned int * critical);
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t structure
|
int indx |
This specifies which OID to return. Use zero to get the first one. | ||
|
void * oid |
a pointer to a buffer to hold the OID (may be null) |
size_t * sizeof_oid
initially holds the size of oid
unsigned int * critical
This function will extract the key purpose OIDs of the Certificate specified by the given index. These are stored in the Extended Key Usage extension (2.5.29.37) See the GNUTLS_KP_* definitions for human readable names.
If oid is null then only the size will be filled.
Returns GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the *sizeof_oid will be updated with the required size. On success 0 is returned.
