@deftypefun {int} {gnutls_x509_crt_print} (gnutls_x509_crt_t @var{cert}, gnutls_certificate_print_formats_t @var{format}, gnutls_datum_t * @var{out})
@var{cert}: The data to be printed

@var{format}: Indicate the format to use

@var{out}: Newly allocated datum with null terminated string.

This function will pretty print a X.509 certificate, suitable for
display to a human.

If the format is @code{GNUTLS_CRT_PRINT_FULL}  then all fields of the
certificate will be output, on multiple lines.  The
@code{GNUTLS_CRT_PRINT_ONELINE}  format will generate one line with some
selected fields, which is useful for logging purposes.

The output  @code{out} needs to be deallocated using @code{gnutls_free()} .

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.
