Of course, as aptly stated by khrafra [1] and many others, it's always 
better to use the prebuilt libraries to do signing.  Here are two 
standard modules that could do authentication:

Standard Python module: http://docs.python.org/library/hmac.html

Google Keyczar: http://www.keyczar.org/

Thanks,

Jason
