If you have ever worried about the security of your documents on your computer then I have just the thing for you. It's called True Crypt, and it will put anything on lock down you don't want prying eyes to see. True Crypt accomplishes this by creating a virtual drive on your computer that is only seen when you log in the program. It uses a very hefty AES with 14 rounds and a 256-bit key. Now I know you are saying "what the hell is that", but to break it down the US National Security Agency has verified that it is strong enough to protect classified material up to Top Secret Level.
Which is more than enough to protect your personal documents. You can also use it for encrypting data on your USB thumb drive, or Ipod as well. As always my favorite theme is that it's free. So check it out and let me know what you think. Also don't worry they give you a step by step guide to set it up. It only took me about 10 minutes to complete the process.
