Free analyzes software for linux

xor-analyze provides a program for cryptanalyzing xor "encryption" with variable key length.
Main features:
- Could possibly crack bad implementations of one-time pads
- Check ftp://ftp.habets.pp.se/pub/synscan/ for windows binaries
To find out what length the password is the ciphertext is XOR-ed against itself with different shifts (see XOR_analyze::coincidence() in analyze.cc) and the number of zeroes (equal bytes) are counted. This is called counting coincidences. When the number of zeroes is high the shift value is potentially a multiple of the key length. The one that stands out most is checked with statistics (with a frequency table) to get the key. To check with statistics on all key-lengths in key-length interval (-m and -M) use the -a switch (with -v for one key per keylength)
Compiling
Type make. Mail me if it doesnt compile and dont forget to tell me what kind of system you have.
Encryption
$ ./xor-enc secret file.txt file.xor

BabyChess is a chess program. You can edit chess games, play chess on the internet, and play locally against engines.
BabyChess is distributed as free software under the terms of the GNU GPL.
Main features:
- Games between humans and/or engines can be played in the match window. XBoard engines are supported.
- The chess position editor lets you edit a chess position, and save it in FEN notation, as used by other chess programs.
- The chess game editor understands PGN notation.
- The game archive editor reads PGN files that contain any number of chess games. It displays a list of all games and lets you edit those games using the game editor.
- The ICS client connects you to an Internet Chess Server and lets you play games against human opponents.
- The "evaluator" of BabyChess is a chess engine that uses its own communication protocol. It is not an XBoard engine. This program is given a FEN position as an argument and analyzes the position. During the thinking process, information about the current best move and more is written.
- The game editor uses the chess evaluator to analyze chess positions.
- Internally, the evaluator uses 64 bit numbers even on 32 bit systems, meaning it is possible to analyze more than 2 billion positions on PCs.
- This program implements an XBoard chess engine. It uses the evaluator as a backend.
- In addition to the standard algebraic notation (SAN). French, German and Dutch notations are supported. Figurine notation is also supported, also the current fonts dont make it look good. New notations can be created.

Directory Analysis Tool is used to analyze LDAP directories and report on their contents.

Useful if you want to find inactive accounts, people who havent changed passwords, or who has administrator privileges.

neurALC project is an open-source cross-platform software for the analysis of multi-electrode recordings.

In the current version it supports experimental data files in the Neural Event Format (NEV 1.x, 2.0, 2.1), and offers functionality to reveal and analyze some of the information contained in such recordings.

It is further intended as a kind of "catalyst" for the development of a free available cross-platform program for the analysis of electrophysiological recordings.

OpticalRayTracer is a free Linux utility that analyzes systems of lenses, it is Xwindows GUI-based.

It uses optical principles and a virtual optical bench to predict the behavior of many kinds of ordinary and exotic lens types. OpticalRayTracer includes an advanced, easy-to-use interface that allows the user to rearrange the optical configuration by simply dragging lenses around using the mouse.

OpticalRayTracer fully analyzes lens optical properties, incuding refraction and dispersion. The dispersion display uses color-coded light beams, as shown above, to simplify interpretation of the results.

Educators take note: OpticalRayTracer has significant educational potential in the teaching of basic optical principles, and it has some entertaining and game-like behaviors to hold the students attention.

OpticalRayTracer includes a detailed tutorial/help file to assist the user in getting started in this interesting activity.

Installation:

Put it in any convenient location.
$ tar -xjf raytracer.tar.bz2
$ cd raytracer.dist
$ ./auto_install.sh
If you dont want the automatic installation or you want to fine-tune the process, instead of running "auto_install.sh", after the unpacking step above, do this:
$ make -f Makefile.cvs dist
$ ./configure
$ make
$ sudo make install
Obviously you may want to modify some of these steps to suit your platform.

Maccess is a program which helps to analyse data in databases.
Maccess helps to analyse data in databases; it is a Web interface to an SQL server. Its main features are user friendly query creation for SQL server; selective, grouped, and crosstab queries; various outputs (XML, HTML, TXT, graphs, and Europe map); data ungrouping in grouped queries; creation of Web links and definition of CSS styles for all values in output; ability to format numbers, dates, and times; and input and data update.
Main features:
- user friendly query creation for SQL server
- selective, grouped and crosstab queries
- various outputs - XML, HTML, TXT fixed, TXT tab, OpenOffice.org, graphs and Europe map
- data ungrouping in grouped queries
- creation of web links and definition of CSS styles for all values in output
- possibility of formating numbers, dates and times
- input and data update
Enhancements:
- This release adds better installation instructions
- some minor bugfixes
- code cleanup for using XML::LibXML version 1.56
- the recode utility has been changed to htmlrecode.

Net::Traces::SSFNet is a Perl module to analyze traces generated by SSFNet.

SYNOPSIS

use Net::Traces::SSFNet qw( droptail_record_player droptail_record_plotter );

$Net::Traces::SSFNet::PRINT_EXACT_DECIMAL_DIGITS = 0;
$Net::Traces::SSFNet::SHOW_SOURCES = 1;
$Net::Traces::SSFNet::SHOW_STATS = 0;

# Use with traces created by either
# SSF.Net.droptailQueueMonitor_1 or SSF.Net.droptailQueueMonitor_2
#
droptail_record_player(q.trace, text.output, some_stream_id.0);

# Use with traces created by SSF.Net.droptailQueueMonitor_1
#
droptail_record_plotter(q.trace, some_stream_id.0, drops, pkts, av_qlen);

# Use with traces created by SSF.Net.droptailQueueMonitor_2
#
droptail_record_plotter(q.trace, some_stream_id.0, drops, pkts, sumpkts, sumdrops);

ABSTRACT

Net::Traces::SSFNet can analyze traces created by Scalable Simulator Framework Network Models. It efficiently emulates in Perl the functionality provided by Java-based, SSFNet-bundled trace analyzers, and adds new features, including allowing for finer granularity in the processed output.

alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, susbstitutional, and mixed employing human-reconstructable algorithms.
alph project provides a pipe filter interface in order to encrypt and decrypt block text to acheive transparency.
The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information.
The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
The program can be conjuncted with pipes reulting in transparent en-decrypt: Atbash, Caesar, Vigenere, Playfair, Vernam.
Enhancements:
- Warnings for unstable cyphers have been added as well as the possibility to unscramble words based on a dictionary file.
- The tools section has been altered to accept pipe strings instead of file operations.
