Cyphering means to encrypt data so as to render unreadable to unwanted

eyes. Your costumers' account details, as well your own, are protect by

cyphering. Here you can choose the algorithm you prefer:

 Rijndael with mcrypt lib. Default choice. Fast and secure.

 custom BlowFish class. Better security, but performance take a

toll, as it takes more time to validate the authentication, this for

each page load. You customers might appreciate the added security,

but might not like the time spent waiting for the page to load.

Ergo, choose wisely.

Caching

Your server's cache stores static versions of your dynamic webpage, in

order to serve these to your customers and thus reduce server load and

compiling time.

This section enables you to choose to enable caching, and choose the

caching method:

 Memcached. A distributed caching system. Very effective, but you

need to make sure that your server/host supports it – most

probably, if your PHP configuration features the Memcached PECL

extension, you're good to go. You can add Memcached servers by

clicking on the "Add server" link.

 File system. The static files are simply stored as any other file, on

your server. You can indicate the directory depth
