Recently I had to encrypt an entire partition to protected some sensitive data. I found out that TrueCrypt is quite easy to use and provide pretty good protection against attackers with physical access to your machine.

You can encrypt your data in two ways:

1) By creating an encrypted file which you then mount as a regular disk

2) By creating an encrypted partition in a similar fashion.
I am running on ArchLinux but you should have any problems installing truecrypt with any distro’s software installer. In case you’d like to do it manually, just follow this link.

When you are done with the installation make sure that you load the kernel module with ‘modprobe truecrypt’. Remember that all commands are executed as ‘root’. You can use a regular user if you give him access to the truecrypt utility through sudo.
