title: SSHing from AWS Instance to AWS Instance using .pem asks for passphrase
body: <p>I am trying to ssh/scp into my AWS instance however it always asks for a passphrase for the .pem file even though there wasn't one set. I have spent hours researching and I have tried everything. Its chmod'ed 400 ( tried 600 and 777 too -no luck) </p>
  
  <p>This is a what I get after pressing enter on the passphrase/password :</p>
  
  <pre><code>  The authenticity of host '****************' can't be established.
      ECDSA key fingerprint is ************************.
      Are you sure you want to continue connecting (yes/no)? yes
      Warning: Permanently added '*********' (ECDSA) to the list of known hosts.
      Enter passphrase for key 'new_bro.pem':
      Permission denied (publickey).
      lost connection
  </code></pre>
  
  <p>and this is a ssh -v message</p>

  <p>I have tried doing it from different machine - same thing. I can login using Putty after converting .pem to .ppk</p>
  
  <p>Please help  </p>
