JaPCrypt

JavaScript and PHP Encryption

What!?

JaPCrypt is a PHP class which purpose is to give encrypted communications over HTTP by using server and client side scriptng like PHP and Javascript. It should be used mostly on administrative sessions, to avoid the stealing of sensitive data. It uses a symmetric encryption algorithm, XTEA, so a pre shared key is required. As it's thought to be used in CMS's administrative sessions, the administrator password could be used as pre-shared key. In order to avoid that the password will be sniffed during the authentication process, done of course via HTTP, JaPCrypt comes with a sample secure login system.
