int gnutls_x509_crt_set_extension_by_oid(gnutls_x509_crt_t crt, const char * oid, const void * buf, size_t sizeof_buf, unsigned int critical);
- gnutls_x509_crt_t crt
a certificate of type gnutls_x509_crt_t
- const char * oid
holds an Object Identifier in null terminated string
- const void * buf
a pointer to a DER encoded data
- size_t sizeof_buf
holds the size of buf
- unsigned int critical
should be non-zero if the extension is to be marked as critical
This function will set an the extension, by the specified OID, in the certificate. The extension data should be binary data DER encoded.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
