gnutls_x509_crt_get_dn3

Api function

Usage

#include <gnutls/x509.h>

int gnutls_x509_crt_get_dn(gnutls_x509_crt_t cert, char * buf, size_t * buf_size);

Arguments

gnutls_x509_crt_t cert

should contain a gnutls_x509_crt_t type

char * buf

a pointer to a structure to hold the name (may be null)

size_t * buf_size

initially holds the size of buf

Overview

This function will copy the name of the Certificate in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC4514. The output string will be ASCII or UTF-8 encoded, depending on the certificate data.

The buf returned will be null terminated and the buf_size will account for the trailing null. If buf is null then only the size will be filled.

This function does not output a fully RFC4514 compliant string, if that is required see gnutls_x509_crt_get_dn3().

Returns

GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the buf_size will be updated with the required size. GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the DN does not exist, or another error value on error. On success 0 is returned.
