Описание (Description)
This function will return the requested extension data in the
certificate. The extension data will be stored in the provided
buffer.
Use gnutls_x509_crt_get_extension_info() to extract the OID and
critical flag. Use gnutls_x509_crt_get_extension_by_oid()
instead, if you want to get data indexed by the extension OID
rather than sequence.

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error code is returned. If you have reached the last
extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be
