title: Python ImportError No module named crypto.PublicKey.RSA
body: <p>When I try to execute a python program, I get this from terminal</p>
  
  <pre><code>Traceback (most recent call last):
  File "ring.py", line 1, in &lt;module&gt;
  import os, hashlib, random, crypto.PublicKey.RSA
  ImportError: No module named crypto.PublicKey.RSA
  </code></pre>
  
  <p>I have no idea how to solve this and other questions have proven completely useless to my situation.</p>
  
  <p>Is the module there but in the wrong place?
  Should I download modules from somewhere like for node.js?
  Or it's more like Java?</p>
