gnutls_x509_crt_get_dn_by_oid - API function
int gnutls_x509_crt_get_dn_by_oid(gnutls_x509_crt_t cert, const
char * oid, unsigned indx, unsigned int
raw_flag, void * buf, size_t *
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t type
- const char * oid
- holds an Object Identified in null terminated string
- unsigned indx
- In case multiple same OIDs exist in the RDN, this specifies which to send.
Use (0) to get the first one.
- unsigned int raw_flag
- If non-zero returns the raw DER data of the DN part.
- void * buf
- a pointer where the DN part will be copied (may be null).
- size_t * buf_size
- initially holds the size of buf
This function will extract the part of the name of the Certificate subject
specified by the given OID. The output, if the raw flag is not used, will be
encoded as described in RFC4514. Thus a string that is ASCII or UTF-8 encoded,
depending on the certificate data.
Some helper macros with popular OIDs can be found in gnutls/x509.h If raw flag
is (0), this function will only return known OIDs as text. Other OIDs will be
DER encoded, as described in RFC4514 -- in hex format with a '#' prefix. You
can check about known OIDs using gnutls_x509_dn_oid_known()
is null then only the size will be filled. If the raw_flag
is not specified the output is always null terminated, although the
will not include the null character.
if the provided buffer is not long enough,
and in that case the buf_size
will be updated with the required size.
if there are no data in the
current index. On success 0 is returned.
