title: Get key signature/fingerprint for GPG Public Key
body: <p>How can I get the key signature from a GPG Public Key?  For example, I need a signature for Spotify's public key here: 
  <a href="https://download.spotify.com/debian/pubkey.gpg" rel="nofollow noreferrer">https://download.spotify.com/debian/pubkey.gpg</a></p>
  
  <p>Something <a href="https://stackoverflow.com/questions/9607295/calculate-rsa-key-fingerprint">like this</a>, but for GPG Keys.</p>
  
  <p>This is as far as I've got:</p>
  
  <pre><code>$ gpg pubkey.gpg 
  pub  4096R/130D1D45 2019-07-15 Spotify Public Repository Signing Key &lt;tux@spotify.com&gt;
  </code></pre>
