Security is the most important thing in our lives, to this end, a lot of tools and algorithms has been created, tools allowing you to encrypt your data. In this article I will provide details on the 2 most commonly used tools/algorithm for data protection, GnuPG and LUKS.

In this article, I will teach you how to use both tools in a different situations, exploring many useful situations… Once you’re done, you will be able to protect and keep your data safe and secured…

It’s very important, when you are choosing an important password, to choose it well, always mix letters ( lower AND upper ), numbers and characters… A week password can be guessed via dictionary attack, like `home` or `computer` etc… A strong password can never be guessed via dictionary attack, ex: `]RmXpEB=1&` or `rl*~V3nM"S` …

I agree that random passwords are very hard to remember, but it’s better safe than sorry right ? Anyway you might think I thought of that password, well guess again

To generate a random, yet powerful, password I use apg it’s a small program that generates passwords, you can request both pronounceable and random passwords.. here some examples:
Generate an 8 to 10 chars long, pronounceable passwords
$ apg -a 0 -m 8 -x 10

Generate 15, 5 to 10 chars long, random passwords
$ apg -a 1 -m 5 -x 10 -n 15

Password Strength
To check the strengh of your password, you can use Password checker by Microsoft.com or this small Java program
