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.
