gnutls_x509_crt_set_serial(3) gnutls gnutls_x509_crt_set_serial(3)
gnutls_x509_crt_set_serial - API function
#include <gnutls/x509.h>
int gnutls_x509_crt_set_serial(gnutls_x509_crt_t cert, const void
* serial, size_t serial_size);
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.
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 certificates in that case may be rejected by other
implementations.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error value.
