title: SSH Service Connection - Cannot parse privateKey: Unsupported key format
body: <p>I'm trying to setup a release pipeline to copy files over to a linux server via ssh. However when I try to run the release I get the following error during the copy task:</p>
  
  <pre><code>Failed to connect to remote machine. Verify the SSH service connection details. Error: Cannot parse privateKey: Unsupported key format.
  </code></pre>
  
  <p>I've tried generating the key multiple times with <code>ssh-keygen -t rsa</code> and uploaded or copied the contents of the private key directly into the Private Key text area in the service connection. All to no avail.</p>
  
  <p>It seems like I'm missing something simple as I can't find much mention of others having issue with this.</p>
