title: Get host key of an ssh server in base 64
body: <p>I'm using paramiko and I need the host key of an ssh server in base 64 for the following line:</p>
  
  <pre><code>key = paramiko.RSAKey(data=base64.decodestring('...'))
  </code></pre>
  
  <p>Does anyone know of a way either through the Mac OS X terminal, in a python script, or something else to find this? Thanks</p>
