gnutls_x509_crq_get_extension_by_oid2 - API function

#include <gnutls/x509.h>

int gnutls_x509_crq_get_extension_by_oid2(gnutls_x509_crq_t */crq/, const char * oid, unsigned indx, gnutls_datum_t * output, unsigned int * critical);*

gnutls_x509_crq_t crq

should contain a gnutls_x509_crq_t type

const char * oid

holds an Object Identifier in a null terminated string

unsigned indx

In case multiple same OIDs exist in the extensions, this specifies which to get. Use (0) to get the first one.

gnutls_datum_t * output

will hold the allocated extension data

unsigned int * critical

will be non-zero if the extension is marked as critical

This function will return the extension specified by the OID in the certificate. The extensions will be returned as binary data DER encoded, in the provided buffer.

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
