This will use ``/dev/urandom`` on UNIX platforms, and ``BCryptGenRandom()`` on
Windows.
If you need your random number as an integer (for example, for If you need your random number as an big integer, you can use
:meth:`~cryptography.x509.CertificateBuilder.serial_number`), you can use
``int.from_bytes`` to convert the result of ``os.urandom``: ``int.from_bytes`` to convert the result of ``os.urandom``:
.. code-block:: pycon .. code-block:: pycon
>>> serial = int.from_bytes(os.urandom(20), byteorder="big") >>> serial = int.from_bytes(os.urandom(16), byteorder="big")
