Moscrack is a WPA cracker for use on clusters. It supports MOSIX, SSH, and RSH connectivity and works by reading a word list from STDIN or a file, breaking it into chunks, and passing those chunks off to separate processes that run in parallel. The parallel processes are then executed on different nodes in your cluster. All results are checked and recorded on your master node. Logging and error handling are taken care of. It is capable of running reliably for long periods of time, without the risk of losing data or having to restart. Moscrack uses aircrack-ng by default. Pyrit for WPA cracking and Dehasher for Unix password hashes are supported via plugins.
Suricata is an Intrusion Detection and Prevention (IDS/IPS) engine developed by the Open Information Security Foundation and its supporting vendors.

TCL2FTP is an extension library for Tcl scripts which allows Tcl programs to perform FTP client and gateway actions. It fully supports the FTP/FXP protocols, is ready for use with SSL/TLS, and is compatible with glFTPd. It can run simple FTP commands, and it supports 25 simultaneous FTP sessions.
mod_auth_pubtkt is a simple Web single sign-on (SSO) solution for Apache. It validates authentication tickets provided by the client in a cookie using public-key cryptography (DSA or RSA). Thus, only the login server that generates the tickets needs to possess the private key, while Web servers can verify tickets given only the public key. The implementation of the login server is left to the user, but an example and a library in PHP are provided with the distribution.
PyKCS11 is a PKCS#11 wrapper for Python. It lets you access almost all PKCS#11 functions and data types using any PKCS#11 library, such as the various modules supplied by smartcard vendors. It comes with two interfaces: a low level and very thin interface over the original PKCS#11 API, generated using the SWIG compiler (designed for library tests), and a high level interface that offers simpler access (with few limits) to the PKCS#11 APIs.
Suhosin is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts that can be used separately or in combination. The first part is a small patch against the PHP core that implements a few low-level protections against buffer overflows or format string vulnerabilities. The second part is a powerful PHP extension that implements all the other protections. Suhosin is binary compatible with plain PHP installations.
