title: Python Authentication API
body: <p>I'm looking for a python library that will help me to create an authentication method for a desktop app I'm writing.
  I have found several method in web framework such as django or turbogears.</p>
  
  <p>I just want a kind of username-password association stored into a local file.
  I can write it by myself, but I'm really it already exists and will be a better solution (I'm not very fluent with encryption).</p>
