SipHash-2-4 implementation, CFFI-wrapped for Python.
It just works. If you have Python ≥ 3.6.
Inspired by https://github.com/majek/csiphash and https://github.com/zacharyvoase/python-csiphash.
$ pip install csiphash24>>> from binascii import hexlify
>>> from csiphash24 import siphash24
>>> hexlify(siphash24(b'0123456789abcdef', b'hello'))

To be honest, I'm not sure. I tried several implementations and they weren't compatible with the device I was working with. This one seems to do the job. So, it might work for you too.
