The JetScripts Text-CAPTCHA stops spambots from filling out your signup pages and contact forms by baffling them with a devious, text-based interlock. This CAPTCHA form is designed to be easy for humans but difficult for spambots. Best of all, it doesn't require graphics libraries like GD or ImageMagick to work. Unlike most CAPTCHA systems, the JetScripts Text-CAPTCHA presents users with a short, simple word instead of oddly-distorted, difficult-to-read random letters. * No graphics libraries required, nothing to configure and no file permissions to set. * Easy-to-read for humans, devilishly tough to crack for spambots! * Over 5,000 different words by default, and more can be added (as many as you want). * "Anti-highlighting" format prevents copying & pasting the CAPTCHA text. * No database required and no special modules or configuration needed. * Doesn't require Javascript- works with Javascript enabled or disabled.

This class can be used to recognize and handle Web robots by IP address or user agent. It can check the IP address of the computer or the user agent of the browser program currently accessing the Web server to determine if it is within a range of IP addresses known to be of Web robots like search engine site crawlers or even malicious crawlers. The class can call different callback functions depending on the type of crawler that was identified. It can also be set on debug mode by taking a given IP address or string as user agent instead of the user agent string sent by the accessing browser. The Web robots information is stored in a database. The class can load that database from a text data file. The database can be accessed using supplied database class or a database adapter class from the Zend Framework.

This class can allow or deny access to a specific port via *nix 'iptables' command. I developed this class because i have an application running under tomcat on port 9521, and there is no way for me to use an apache 'htaccess' method to manage accesses to this port. With this script i have created a web page redirecting browser requests to tomcat server. For all granted access, will be inserted in my firewall list a rule with port 9521 access. User can be enabled with user/password or by ip.

Unlike products that only encode the sources and decode them at runtime, selling only an illusion of protection, OBFUSC is a real obfuscator, with no extensions installed on servers and providing full control over the obfuscation process through a nice and powerfull user interface. OBFUSC incorporates a true PHP parser to ensure that all the syntax is properly handled. You can decide case by case if an identifier should be or not obfuscated. The default settings and decisions provide around 90% rate of obfuscation without human intervention for a normal project. You can make manual decisions and rise this rate in cases where OBFUSC is not 100% sure that understand all code intentions. If you want to preserve names as a part of an API for customers you can easily do this, too. From interface you can choose what files are not to be obfuscate and all identifiers used in those files will not be scrambled in the rest of the project.
