title: Openssh Private Key to RSA Private Key
body: <p>(I am using MAC)</p>
  <p>My id_rsa starts with</p>
  <pre><code>-----BEGIN OPENSSH PRIVATE KEY-----
  </code></pre>
  <p>but I expect it to starts with</p>
  <pre><code>-----BEGIN RSA PRIVATE KEY-----
  </code></pre>
  <p>I have send my id_rsa.pub to server administrator to get the access to server, so I don't want to generate a new key.</p>
  <ol>
  <li><p>Is there any way that I can transfer my id_rsa which is a openssh private key to a RSA private key?  (command please.)</p>
  </li>
  <li><p>If I can transfer, do I also need to transfer id_rsa.pub? (command please.) It seems id_rsa.pub doesn't have a header like id_rsa, so I am not sure if I should also transfer this.</p>
  </li>
  </ol>
