Multi Purpose Scanner is a simple scanner written in C that starts a number of child processes, connects to a list of IP addresses, and logs a certain number of characters to standard out or a file.
Low band use is one consecuence of a single connection per child that recieve an only defined num of characters.
Main features:
- $ mpscan -e -p 25 -t 15 -r 100 -T 20 -R 192.168.1.0-10
- Fast mp-scan 0.04-testing ...
- Total ip: 11
- 11/11 91% 192.168.1.10
- Generated 11 ip in 0.199 seconds
- Ip range parsed... 11 ip found
- Scan on 25 started...
- 0:192.168.1.0 -> Network is unreachable

Cryptomak Cipher Tools project consists of a collection of PHP scripts for encryption purposes.
Cryptomak contains a cipher and tools for encryption utilities written in PHP, including substitution, vigenere, affine, transposition, and index of coincidence.
It is powered by the Phrame platform which implements MVC design and the Smarty template engine.
Enhancements:
- It is programmed in modular programming. Welcome to OOP world ;)
- Using Phrame as web aplication platform which implements MVC design
- Using Smarty as template engine at the view layer
- New hashing script added
- Better web design

App::perlstyle is a App::Context Perl Style Guide.

The following document describes some of the coding standards used in writing the App::Context framework (App-Options, App-Context, App-Repository, App-Widget, and other minor distributions). This document exists for two purposes:

1. To provide a guideline for people who wish to contribute to or extend code in the App::Context framework.
2. To provide a samples style guide to any development group who desires a simple, effective coding standard for programming in Perl.

Note that these are all guidelines, not unbreakable rules.

Note that with much of this document, it is not so much the Right Way as it is One Reasonable Way. Everyone needs to have conventions in order to make life easier.

The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library.
OpenSSL project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the OpenSSL toolkit and its related documentation.
OpenSSL is based on the excellent SSLeay library developed by Eric A. Young and Tim J. Hudson. The OpenSSL toolkit is licensed under an Apache-style licence, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.
Main features:
- Creation of RSA, DH and DSA key parameters
- Creation of X.509 certificates, CSRs and CRLs
- Calculation of Message Digests
- Encryption and Decryption with Ciphers
- SSL/TLS Client and Server Tests
- Handling of S/MIME signed or encrypted mail

mod_cgi is an Apache module that turns a CGI program into a dynamically loaded library (.so) and runs it without forking. Gives the simplicity and portability of CGI without the overhead.

There is no documentation, beyond the source code comments. It will build cleanly with Apache 1.3b6+, and youll need some configuration: e.g.

AddHandler mod_ecgi .so

or

AddType x-embedded-cgi .so

As I said, see the source file.

Theres also a small harness for CGI programs, to get round the way many sloppy CGIs never return but call exit() instead. Its not absolutely necessary, but for most purposes youll want it.

SdlZombies project is a zombie game clone.
The purpose of the game is to attract zombies and make them fall in holes.
Enhancements:
- Remove : all tty debug output.
- Final version !

CTris its mainly a tetris clone made by me for educational purposes, you can try to
have a look at the code but unfortunately its terribly messy and with few comments.

If you want to compile it from the sources you will need the DUMB libraries.

pppit allows one to tunnel through a firewall which only allows proxy telnet, such as SWAN. It is a modified, special-purpose ppp daemon.
