gnutls_x509_crt_set_serial(3) gnutls gnutls_x509_crt_set_serial(3)

NAME

gnutls_x509_crt_set_serial - API function

SYNOPSIS

#include <gnutls/x509.h>
int gnutls_x509_crt_set_serial(gnutls_x509_crt_t cert, const void * serial, size_t serial_size);

ARGUMENTS

gnutls_x509_crt_t cert
a certificate of type gnutls_x509_crt_t
const void * serial
The serial number
size_t serial_size
Holds the size of the serial field.

DESCRIPTION

This function will set the X.509 certificate's serial number. While the serial number is an integer, it is often handled as an opaque field by several CAs. For this reason this function accepts any kind of data as a serial number. To be consistent with the X.509/PKIX specifications the provided serial should be a big-endian positive number (i.e. it's leftmost bit should be zero).
The size of the serial is restricted to 20 bytes maximum by RFC5280. This function allows writing more than 20 bytes but the generated certificates in that case may be rejected by other implementations.

RETURNS

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
