The Blowfish cipher

The Blowfish cipher


The Blowfish cipher in C and i386 assembler. more>>
The Blowfish cipher in C and i386 assembler.

In cryptography, Blowfish is a keyed, symmetric block cipher, designed in 1993 by Bruce Schneier and included in a large number of cipher suites and encryption products. While no effective cryptanalysis of Blowfish has been found to date, more attention is now given to block ciphers with a larger block size, such as AES or Twofish.

Schneier designed Blowfish as a general-purpose algorithm, intended as a replacement for the aging DES and free of the problems associated with other algorithms. At the time, many other designs were proprietary, encumbered by patents or kept as government secrets. Schneier has stated that, "Blowfish is unpatented, and will remain so in all countries. The algorithm is hereby placed in the public domain, and can be freely used by anyone."

autocrypt 0.0.3

autocrypt 0.0.3


autocrypt is an automatic crypted disk mapping creation with rootplug. more>>
autocrypt its a set of scripts that use linux hotplug/udev/cryptoapi mechanism to allow you autocrypting a harddrive what do I means by autocrypting : I means using a "rootplug" ie an identification device to activate the possibility of mounting automatically a crypted device.

Youll need such tool if typically you have some data you require to protect whith cryptography and that you want not creating the node "by hand" each time (this require root privileges) look at the following scenario :

you work into a company which data are sensitives
you dont want to encrypt your home using pam crypt because
you dont want to have to setup your workspace each time you come back.

So you dant want to logout, using a screensaver to prevent use of your computer. But while youre loged the data are accessible.... a malicious hacker can login to you box via network and have access to your data....

You can manually create the cryting device mounting and umounting them at demand but this means you have root privilege you can use a special identification device, a "key" that do it for you.... thats autocrypt this solution use the widely available usbkeys/drives to create the unencrypted devices when the key is pluged and to remove it safely when the device is removed.

Play What I Mean 0.09

Play What I Mean 0.09


Play What I Mean plays media files on a local machine based on a given set of terms found within the filenames. more>>
Play What I Mean project allows a user to, from a single commandline or terminal, enter a string, or list of strings, that represent what he/she wishes to have played by whatsoever media player he chooses, the default being MPlayer, and then having that particular item be found and played.
What this essentially means is that if I were to have a sudden hankering to listen to a particular song or video, lets say Ice Pick by The Pillows, which happens to be the song to a particular music video that I enjoy watching. Under the traditional methods of video viewing I would be stuck with two potential courses of action for playing this particular file:
- Change directories several times to that one folder somewhere that I "know" its in, or
- Point and Click my mouse until I find that same directory and then search through what could be countless files to find it.
Each of these prospective choices have their own inherent difficulties and ire. Using the commandline often requires alot of typing to arrive at the desired directory, often times nestled deep within the tree.
Once there your problems only multiply by the number of files you actually store in your "media" folder, try ls | moreing through a heavily populated folder looking for the name of that file you wanted to play sometime, it isnt too fun and further is a waste of my valuable time.
You may be thinking at this point that the second option, the graphical one, must be easier since its exciting, full of pictures, and frankly novel, I disagree. I may not be the best judge on this matter, seeing as how I cant see out of my right eye however, I feel that scanning through a large folder, or folders, full of files is quite a strain on the vision, and more importantly an unnescesary burden on what should be a simple matter.
Main features:
- Nestable Playlist support
- Multi-string arguments
- Transparent command option passing
- Cache for faster access of frequently played files
- Graphical configure

Trfcrypt 1.2

Trfcrypt 1.2


Trfcrypt is an add-on package to the tcl-extension trf. more>>
trfcrypt is an add-on package to the tcl-extension trf. It provides the encryption functionality which was removed from the base package to allow its inclusion on the Tcl/Tk CDROM without violating US export control laws on cryptography.
The C API is layered on top of the trf C API and provides a set of commands for the management, implementation and usage of blockciphers and stream.
Although it is possible to implement ciphers using only the trf C API the code in this package makes it much easier, as general things like the handling of blockcipher modes are done here, thus obviating the need to reimplement them every time. A new cipher just has to provide some information about itself (key sizes) and functions to:
- generate the internal keyschedule from the specified key
- encrypt/decrypt a character or a block of data

Crypt::UnixCrypt 1.0

Crypt::UnixCrypt 1.0


Crypt::UnixCrypt is a perl-only implementation of the crypt function. more>>
Crypt::UnixCrypt is a perl-only implementation of the crypt function.

SYNOPSIS

use Crypt::UnixCrypt;
$hashed = crypt($plaintext,$salt);

# always use this modules crypt
BEGIN { $Crypt::UnixCrpyt::OVERRIDE_BUILTIN = 1 }
use Crypt::UnixCrypt;

This module is for all those poor souls whose perl port answers to the use of crypt() with the message `The crypt() function is unimplemented due to excessive paranoia..

This module wont overload a built-in crypt() unless forced by a true value of the variable $Crypt::UnixCrypt::OVERRIDE_BUILTIN.

If you use this module, you probably neither have a built-in crypt() function nor a crypt(3) manpage; so Ill supply the appropriate portions of its description (from my Linux system) here:

crypt is the password encryption function. It is based on the Data Encryption Standard algorithm with variations intended (among other things) to discourage use of hardware implementations of a key search.

$plaintext is a users typed password.

$salt is a two-character string chosen from the set [a-zA-Z0-9./]. This string is used to perturb the algorithm in one of 4096 different ways.

By taking the lowest 7 bit of each character of $plaintext (filling it up to 8 characters with zeros, if needed), a 56-bit key is obtained. This 56-bit key is used to encrypt repeatedly a constant string (usually a string consisting of all zeros). The returned value points to the encrypted password, a series of 13 printable ASCII characters (the first two characters represent the salt itself).
Warning: The key space consists of 2**56 equal 7.2e16 possible values. Exhaustive searches of this key space are possible using massively parallel computers. Software, such as crack(1), is available which will search the portion of this key space that is generally used by humans for passwords. Hence, password selection should, at minimum, avoid common words and names. The use of a passwd(1) program that checks for crackable passwords during the selection process is recommended.

The DES algorithm itself has a few quirks which make the use of the crypt(3) interface a very poor choice for anything other than password authentication. If you are planning on using the crypt(3) interface for a cryptography project, dont do it: get a good book on encryption and one of the widely available DES libraries.
