Why secure data


In the electronic age, information that could otherwise benefit or educate a group or individual can also be used against such groups or individuals.
A letter to your girlfriend may result in a letter from your wife's lawyer.

What is encryption?


Encryption is the conversion of data into a form, called a cipher text, that cannot be easily understood by unauthorized people.
Encryption is the process of transforming information using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key.

Hello bad guy,

I am giving you a valuable information regarding my company. With that information you can ruin my company.

We need tool so that we cay easily encrypt and decrypt our data
Many commercial and free version available
Built in technology in OS
T r u e C r y p t is free open-source disk encryption software for  Linux, Mac and Windows.


Features of Truecrypt


Creates a virtual encrypted disk within a file and mounts it as a real disk.
Encrypts an entire partition or storage device such as USB flash drive or hard drive.
Encryption is automatic, real-time (on-the-fly) and transparent

Main Features


Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
1) No TrueCrypt volume can be identified
2) Hidden volume (steganography)   and hidden operating system.

  • Standard Truecrypt volume
  • Hidden volume
Truecrypt can be found at http://www.truecrypt.org/
Truecrypt tutorial can be found athttp://www.truecrypt.org/docs/?s=tutorial http://www.truecrypt.org/docs/

Disadvantages of encryption


Extra processing
Slow access to data
Extra memory consumed
Data can be rendered useless if the key is lost
Forceful retrieve of key makes encryption useless

[Solved] invalid partition table on /dev/sda -- wrong signature 0.

Roshan Karki Anonymous
I was trying to use Disk Utility program to edit some partition in my system. But I got a strange error message "invalid partition table on /dev/sda -- wrong signature 0." and couldn't proceed. So I tried with gparted(Gnome Partition Editor). The result wasn't any different. Today while clean installing Ubuntu 11.10 Oneiric Ocelot, the installer said that there was no partition in my disk. While trying live CD, I could find all the partition and read data. If you also encounter any of the above problem, simple run fdisk by sudo fdisk /dev/sda press p and then press w . You'll see a message "The partition table has been altered!". Now try running the partition editor or the installer again.
