X509_GET_SERIALNUMBER(3)	    OpenSSL	      X509_GET_SERIALNUMBER(3)

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.
