pks-commands.php3 allows your Web server to search and add PGP/GPG keys from the public keys out there. It takes the TCP 11371 port connection and does it all on the web server. It is good in environments where the client machines are unable to get to arbitrary TCP ports (such as behind tightened firewalls).
OpenPGP Webmail is a set of PHP scripts which allows anonymous Web users to send encrypted email to anyone with PGP or GPG keys. It is designed to run over SSL, and has a key search facility built in. GnuPG is required to do the encryption. The project is now abandonware. Anyone can take it over if they like.
Care2x (formerly Care 2002) is software for hospitals and health care organizations. It is designed to integrate the different information systems existing in these organizations into a single efficient system. It solves the problems inherent in a network of multiple programs that are incompatible with each other. It can integrate almost any type of services, systems, departments, clinics, processes, data, or communication that exist in a hospital. Its design can even handle non-medical services or functions like security or maintenance. All of its functions can be accessed with a Web browser, and all program modules are processed on the server side.
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.
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.
Lasso (Liberty Alliance Single Sign On) is an implementation of the Liberty Alliance specifications. These specifications define protocols for federated identities, single sign-on, etc. Lasso supports ID-FF 1.2, SAML 2.0, and parts of ID-WSF. It provides both a C library and bindings for several languages (Python, Java, Perl, PHP 4, and PHP 5).
rfrandpass is a PHP application that generates random passwords according to your specifications (minimum length, number of alpha/numeric/symbol characters, etc). It features many output crypt and hashing options. Also included is a native PHP library for performing NT and LM hashing.
