title: Recommended Python cryptographic module?
body: <p>I've been exploring what cryptographic modules are available to Python, and I've found 3: ezPyCrypt, yawPyCrypt and KeyCzar (which actually supports a few languages, but Python is included amongst them). The first two rely on the PyCrypto module.</p>
  
  <p>Are there choices I am missing? Is there a clear front-runner for ease and features or does it simply come down to a manner of one's comfort level?</p>
  
  <p>I'm currently leaning towards KeyCzar, with ezPyCrypt close behind.</p>
  
  <p>I would be using the library for digital signature signing and verification, and potentially for key creation (although I won't cry if I have to make a call to something else for that functionality).</p>
  
  <p>I am using Python 3.x and have access to GPG.</p>
