X509_GET_SERIALNUMBER(3ossl) OpenSSL X509_GET_SERIALNUMBER(3ossl)
NAME
X509_get_serialNumber, X509_get0_serialNumber, X509_set_serialNumber,
X509_ACERT_get0_serialNumber, X509_ACERT_set1_serialNumber - get or set
certificate serial number
SYNOPSIS
#include <openssl/x509.h>
ASN1_INTEGER *X509_get_serialNumber(X509 *x);
const ASN1_INTEGER *X509_get0_serialNumber(const X509 *x);
int X509_set_serialNumber(X509 *x, ASN1_INTEGER *serial);
#include <openssl/x509_acert.h>
ASN1_INTEGER *X509_ACERT_get0_serialNumber(X509_ACERT *x);
int X509_ACERT_set1_serialNumber(X509_ACERT *x, ASN1_INTEGER *serial);
DESCRIPTION
X509_get_serialNumber(3) returns the serial number of certificate x as
an ASN1_INTEGER structure which can be examined or initialised. The
value returned is an internal pointer which MUST NOT be freed up after
the call.
X509_get_serialNumber(3) except
it accepts a const parameter and returns a const result.
X509_set_serialNumber() sets the serial number of certificate x to
serial. A copy of the serial number is used internally so serial should
be freed up after use.
X509_ACERT_get0_serialNumber() performs the same operation as
X509_get_serialNumber(3) for attribute certificates.
X509_ACERT_set1_serialNumber() performs the same operation as
X509_set_serialNumber() for attribute certificates.
RETURN VALUES
X509_get_serialNumber(3), X509_get0_serialNumber() and
X509_ACERT_get0_serialNumber() return a pointer to an ASN1_INTEGER
structure.
X509_set_serialNumber() and X509_ACERT_set1_serialNumber() return 1 for
success and 0 for failure.

HISTORY
The X509_get_serialNumber(3) and X509_set_serialNumber() functions are
available in all versions of OpenSSL. The X509_get0_serialNumber()
function was added in OpenSSL 1.1.0. The
X509_ACERT_get0_serialNumber() and X509_ACERT_set1_serialNumber()
functions were added in OpenSSL 3.4.
