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.
