title: Is it safe to change the 'Security.salt' line to a more lengthy string {64 hex key}
body: <p>I have changed the <pre><code>Configure::write('Security.salt', '############');</code></pre> value in the file </p>
  
  <blockquote>
    <p>config/core.php</p>
  </blockquote>
  
  <p>file to a '256-bit hex key'. Is it safe or a good practice to change these lines for every different installation of cakephp application or shall I revert back to the original ?</p>
  
  <p>I also changed the <pre><code>Configure::write('Security.cipherSeed','7927237598237592759727');</code></pre> to a different one of more length.</p>
  
  <p>Please throw some light on this.</p>
  
  <p>Thanks</p>
