title: Is there a way to "autosign" commits in Git with a GPG key?
body: <p>Is there an easy way to make Git always signs each commit or tag that is created?</p>
  
  <p>I tried it with something like:</p>
  
  <pre>alias commit = commit -S</pre>
  
  <p>But that didn't do the trick.</p>
  
  <p>I don't want to install a different program to make this happen. Is it doable with ease?</p>
  
  <p>Just a side question, maybe commits shouldn't be signed, only tags, which I never create, as I submit single commits for a project like Homebrew, etc.</p>
