title: How to pass private key as text to ssh?
body: <p>I'm using one service which is connected to remote host via ssh. I don't  want to store or write ssh keys on that service, I want pass keys to service  and execute <code>ssh</code> connection to another host using passed keys before.</p>
  
  <p>To connect to host I used: <code>ssh user@host -i /path/to/key</code>.</p>
  
  <p>How can I use key as the <code>text</code> not a specific file?
  I tried <code>ssh user@host -i "key-text-example"</code>. It doesn't  work like that.</p>
