The Enhanced File Crypt/eXtended File Stealth System (EFC/XFSS) makes your uploaded files safe on the server so that no one can read them without knowing a few details to decipher the files. It generates different obfuscated names and encrypted files so no one will know what the original format or name was.
Link Protect will prevent direct linking, downloads, and spider searches of your images and pages that would otherwise enable unauthorized downloads. If the call is not from within your site or an authorized site, a customizable default image is displayed. You can specify domains from which you will accept links such as your other sites or those of authorized associates. Almost any type of file can be protected (GIF, JPEG, zip, HTML, exe, etc.).
PHPCoder is a Web-based frontend to the Turck MMCache encoding functions, which are similar to the Zend Encoder product. PHPCoder enables you to encode your PHP scripts and applications into non-reversible bytecode, thus preventing users of your programs from viewing or altering the source code while having full functionality. Another excellent use for PHPCoder is to encode your applications PHP configuration files, that way someone viewing your source code does not see your databae login and password information. It also allows you to set restrictions on the encoded scripts, you can lock a script to a particular server IP address, server host name, visitor IP, or even place a time limit on the script so it will expire after a configurable amount of time. You specify Text, HTML, or PHP code that should be prepended and appended to each file before it is encoded, allowing you to easily and securely implement your own licensing scheme.
