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 * se-
rial, 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. its
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 cer-
tificates in that case may be rejected by other implementations.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er-
ror value.
