X509_GET_SERIALNUMBER(3ossl) OpenSSL X509_GET_SERIALNUMBER(3ossl)
NAME
X509_get_serialNumber, X509_get0_serialNumber, X509_set_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);
DESCRIPTION
X509_get_serialNumber() 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_get0_serialNumber() is the same as X509_get_serialNumber() 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.
RETURN VALUES
X509_get_serialNumber() and X509_get0_serialNumber() return an
ASN1_INTEGER structure.
X509_set_serialNumber() returns 1 for success and 0 for failure.

function was added in OpenSSL 1.1.0.
