"TinFoil Hat Linux is a small Linux distribution that can be easily booted from a floppy disk. As from my perspective its two best sides are that you have your ring pair backuped on one place and that you can securely encrypt and decrypt files wherever you are located. TinFoil Hat Linux is created to be a little paranoid place, so its other features surely go door-to-door with paranoia:

Anti KeyLogger feature: KeyLoggers are little software or hardware pests that are installed by people with malicious intent (for instance if your computer has been compromised so a KeyLogger is installed to snoop all your keystrokes and send them to attacker's e-mail address) or by people within the company infrastructure (that usually install hardware KeyLoggers to spy on what their employees spend their business time on). If you are on a non secure computer and you really need to use encryption, TinFoil Hat Linux has a nifty feature that gives you the abbility of entering your password in a secure manner, so the hardware KeyLogger (TinFoil Hat Linux boots from a floppy and as it is a seperate Operating System software keyloggers from other OS on this computer, of course, cannot work) and the people that check its logs cannot get to your passphrase. TinFoil Hat Linux used a wrapper for GPG, called gpggrid, that lets you use a video game style character entry system instead of typing in your passphrase. Don't think that it is something heavily graphical, as it is just a simple grid where column and row characters are randomly being changed. This finishes up with the possible KeyLogger getting aZ zT jP cJ aM hY instead of your passphrase "sensei" (just an example).

Anti Tempest feature: As seen from the readme.txt file attributed to this small Linux distribution - " TinFoil Hat Linux uses ctheme to manipulates the VGA console palette. It's an amusing hack, and does make it harder to photograph the screen with a digital camera, but it won't complicate tempest observation. It's the best I could figure out without having greyscale fonts." This feature is very interesting if you are into illuminati and big brother theories. What the heck - if your encrypted file is worth 2 million dollars, you should be afraid of people looking your screen over your shoulder, agents using their machines to grab your monitor signals, corporate spies using tele-kynesis powers and... and... well, you watched Enemy of the State, didn't you? BTW what to say about a software package that is being described by its author with the following line - "An exercise in paranoia or a day to day tool". Also, the thing degrates in a positive anti-paranoia sense - in order to complicate listening to radiation from the keyboard, TinFoil Hat Linux blinks encrypted messages in morse code on the keyboard LEDs."
