I have two warnings related to cakephp security
Please change the value of 'Security.salt' in app/Config/core.php to a salt value specific to your application [CORE\Cake\Utility\Debugger.php, line 717]
Please change the value of 'Security.cipherSeed' in app/Config/core.php to a numeric (digits only) seed value specific to your application [CORE\Cake\Utility\Debugger.php, line 721]
But I have no idea of what that actually means. Is it just alright to leave them as they are even in really large and important applications ?
