gnutls_x509_crt_get_dn_by_oid: API function
NAMEgnutls_x509_crt_get_dn_by_oid - API function
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t structure
- const char * oid
- holds an Object Identified in null terminated string
- int 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
DESCRIPTIONThis 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().
RETURNSGNUTLS_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 there are no data in the current index. On success 0 is returned.
