[UPHPU] Token Authentication

[Chad Sollis]

Greetings,
I am building a webservice that I would like to require authentication to
access.  What would be a best practice (and perhaps a light how-to) on
secure authentication, preferably using a token/shared key.

Unfortunately, the client consuming the webservice will likely not have a
lot of flexibility on generating anything dynamic to pass along with the
request.  Is this even possible, if the parameters are static on their side?

I am open to any and all suggestions.

thank you for your help.
