title: Must I generate SSH key for each my computer, or to copy the `~/.ssh` directory's content is enough?
body: <p>I use <a href="http://git-for-windows.github.io/" rel="nofollow">Git for Windows</a>. I have done all steps of <a href="https://help.github.com/articles/generating-ssh-keys/" rel="nofollow">this</a> instruction. It works fine. Must I generate the SSH key for each my computer, or to copy the <code>~/.ssh</code> directory's content is enough (from my office computer to my home notebook)? Can I use the same SSH key for both computers?</p>
