TrueCrypt – Free Disk Encryption Software

TrueCrypt is a Free, open-source disk encryption software for Windows XP/2000/2003 that encrypts on the fly.

Main Features:

  • It can create a virtual encrypted disk within a file and mount it as a real disk.
  • It can encrypt an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc.
  • Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
    1. Hidden volume (more information may be found here).
    2. No TrueCrypt volume can be identified (TrueCrypt volumes cannot be distinguished from random data).
  • Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5, Serpent (256-bit key), Triple DES, and Twofish (256-bit key). Supports cascading (e.g., AES-Twofish-Serpent).
  • Based on Encryption for the Masses (E4M) 2.02a, which was conceived in 1997.

PyKeylogger 0.6.5 released

PyKeylogger is a simple keylogger written in python. It is primarily designed for personal backup purposes, rather than stealth keylogging (though it can do that, too). It does not raise any trust issues, since it is a short python script that you can easily examine.

This is a bugfix release. Fixed the first-ever reported bug (1323518), logging to onefile.

Open Office RC3 made available for free download a third release candidate of Version 2.0 of its popular open-source office suite Friday. The release includes bug fixes only and no new features.

The project had planned to release its final 2.0 version on Oct. 13—the fifth anniversary of the founding of the organization—but it decided to hold off due to a “show-stopping” problem with the software. No new date has been attached to the final release, but community manager Louis Suarez-Potts said it could be ready as early as next week or as late as the end of the month.

Ubuntu OEM Installation

An OEM (Original Equipment Manufacturer) installation mode is now available for Ubuntu 5.10. This will help OEMs (lke HP, Dell or even your local computer store) to pre-install Ubuntu on a computer and sell it to you. Once you buy the computer, the first time you power up, you will be asked to set your time zone, create a new user and basically customize the computer for your use.

With the OEM installation mode, it is hoped that more and more vendors will pre-install Ubuntu on the computers they sell. This would increase the number of Home users using Free Softwares like GNU/Linux. OEM Installation can be done easily using the Install CD.
Here are the steps for OEM Installation:

The Ubuntu Wiki has some documentation about the OEM Installer. Here are the seven easy steps.

  1. Place the Ubuntu 5.10 Install CD in the CD-ROM Drive and power on the computer.
  2. At boot:, type oem and press Enter.
  3. The Ubuntu 5.10 installer will run. Follow the on-screen instructions to start the installation.
  4. Once the installation is complete, you will be informed that Ubuntu 5.10 has been fully installed and the computer is ready for shipping.
  5. You can also run a system test to check if the installation of Ubuntu 5.10 OEM mode went smoothly. The system test will run the Ubuntu Hardware Database and will check if the hardware is configured correctly.
  6. Sell the Computer (The next step is for the potential buyer)
  7. Power on your new Ubuntu-powered computer (or laptop!). You will be asked to select your language, keyboard layout, time zone configuration, and create your first user account. The first user account created has administrative rights via sudo. Since Ubuntu 5.10 is a multi-user system, you can create more user accounts as needed.

About Free Software Blog

Welcome to Free Software Blog.
My name is Srinivasan and I have started this blog where I will post about the various Free Softwares available and how they could be used as a viable alternative to the proprietary ones.

I need to emphasise here about what I mean by Free Softwares.
Free software, as defined by the Free Software Foundation, is software which can be used, copied, studied, modified and redistributed without restriction. Freedom from such restrictions is central to the concept of “free software”, such that the opposite of free software is proprietary software, and not software which is sold for profit, such as commercial software. Free software may sometimes be known as libre software, FLOSS, or open source software.

According to Richard M Stallman and the FSF, Softwares which provides the following four freedoms are classified as Free Software.

  • the freedom to run the program for any purpose (called “freedom 0”)
  • the freedom to study and modify the program (“freedom 1”)
  • the freedom to copy the program so you can help your neighbor (“freedom 2”)
  • the freedom to improve the program, and release your improvements to the public, so that the whole community benefits (“freedom 3”)

See the FSF Website to know more about Free Software and Freedom

In this blog I will post tutorials, tips and tricks on using free softwares instead of the proprietary ones, so that you would have the above mentioned freedoms. You can also comment on my articles so that it makes me to think. If you want me to write about some specific content, then please write to me at
