12 int gnutls_x509_crt_get_dn_by_oid(gnutls_x509_crt_t cert, const char *
13 oid, int indx, unsigned int raw_flag, void * buf, size_t * sizeof_buf);
14
16 gnutls_x509_crt_t cert
17 should contain a gnutls_x509_crt_t structure
18
19 const char * oid
20 holds an Object Identified in null terminated string
21
22 int indx In case multiple same OIDs exist in the RDN, this specifies
23 which to send. Use zero to get the first one.
24
25 unsigned int raw_flag
26 If non zero returns the raw DER data of the DN part.
27
28 void * buf a pointer where the DN part will be copied (may be null).
29
30 size_t * sizeof_buf
31 initially holds the size of buf
32
34 This function will extract the part of the name of the Certificate sub‐
35 ject specified by the given OID. The output, if the raw flag is not
36 used, will be encoded as described in RFC2253. Thus a string that is
37 ASCII or UTF-8 encoded, depending on the certificate data.
38
39 Some helper macros with popular OIDs can be found in gnutls/x509.h If
40 raw flag is zero, this function will only return known OIDs as text.
41 Other OIDs will be DER encoded, as described in RFC2253 -- in hex for‐
42 mat with a 'using gnutls_x509_dn_oid_known().
43
44 If buf is null then only the size will be filled.
45
46 Returns GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long
47 enough, and in that case the *sizeof_buf will be updated with the
48 required size. On success 0 is returned.
