<span style="color: #444444; font-family: Arial, Helvetica, sans-serif; font-size: large;">Turn the whole world into a keyboard! It's a simple Invention Kit for Beginners or Experts doing art, engineering, and everything in between. Using the MaKey MaKey you can make anything and everything into a key just by connecting a few crocodile clips. The MaKey MaKey is an invention kit that tricks your computer into thinking that almost anything is a keyboard. This allows you to use up all kinds of fun things as an input. For example, play Mario with a Play-Doh keyboard, or piano with fruit!</span></div>

<div style="text-align: justify;">
<span style="color: #444444; font-family: Arial, Helvetica, sans-serif; font-size: large;">The MaKey MaKey uses high resistance switching to detect when you've made a connection even through materials that aren't very conductive (like leaves, fruits or people). This technique attracts noise on the input, so a moving window averager is used to lowpass the noise. The on-board ATMega32u4 communicates with your computer using the Human Interface Device (HID) protocol which means that it can act like a mouse or keyboard.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: Arial, Helvetica, sans-serif; font-size: large;"><br /></span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: Arial, Helvetica, sans-serif; font-size: large;">There are six inputs on the front of the board, which can be attached to via crocodile clipping, soldering to the pads, or all other methods you can think of. There are another 12 inputs on the back, 6 for keyboard keys, and 6 for mouse motion, which you can access with jumpers via the female headers. If you wish to use a different set of keys, or otherwise change the behavior of your MaKey MaKey, you can simply reprogram it using the Arduino environment. And yes, MaKey MaKey is an Arduino-compatible controller!That's right, it runs the Leonardo bootloader so reprogramming is fast and easy.</span></div>

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif; font-size: large;"><b>Password cracking-</b></span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif; font-size: large;"><br /></span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Password cracking is usually done by either repeatedly guessing the password,</span><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">its done using computer algorithm in which computer tries numerous combinations until the password is successfully discovered.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Password cracker use two primary methods to identify correct passwords:</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">1)Brute force</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">2)Dictionary searches</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;"><br /></span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">In this tutorials we going to use brute force method to crack password.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Brute force: When password cracker uses a brute force tool, tests all possible combination of characters of predetermined length </span><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">until its finds the right combination accepted by the computer system.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Brute force is generally trial and error method used by application programs to decode encrypted data.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Brute force is considered to be an infallible but time consuming approach.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;"><br /></span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">In this tutorial we gonna use Mozilla Firefox addons- Fireforce.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">If you don't have Mozilla Firefox version 20.0 installed the version am using and also required addons please see my previous post </span></div>

<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">I hope you have installed addons and the version of Mozilla Firefox</span><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;"> am  using.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">For this method you must know the username to successfully cracking the password.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Lets start------</span></div>
<div style="text-align: justify;">

<br />
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;">STEP 4)This will asks for the minimum and maximum number of characters that the password requires, and also the message required to detect the failure or success.</span></div>
<div style="text-align: justify;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif; font-size: large;"> In this case, our failure text is "Login Failed!". </span></div>

<h3>
<span style="font-size: large;">Hacking tutorial Episode 1--></span></h3>
<h4>
<span style="font-size: large;">INTRODUCTION--></span></h4>
<span style="font-size: large;">Hacking is the gaining of access(wanted or unwanted) to a computer and viewing, copying, or creating data(leaving a trace) without the intention of destroying data or maliciously harming the computer. </span><br />
<span style="font-size: large;"> And who is Hacker ...According to me hacker is "A clever programmer" who tries to break into computer system.</span><br />
<span style="font-size: large;"> There's not more to talk about Hacking in introduction because we all are fimilar with it.</span><br />
<span style="font-size: large;"><br /></span><span style="font-size: large;">INITIAL SETUP--></span><br />
<span style="font-size: large;"><br /></span><span style="font-size: large;">Before starting this tutorial you need to install following software.</span><br />
<span style="font-size: large;">1>Mozilla Firefox</span><br />
<span style="font-size: large;">   Installing Firefox is most important procrdure in this tutorials.</span><br />
<span style="font-size: large;">   Moilla Firefox browser is known as Hackers Browser for the following reasons--></span><br />
<span style="font-size: large;">    1.Firefox provide you great add-ons and this add-ons are helpful for hackers.</span><br />
<span style="font-size: large;">    2.Chrome and some other browser filter data and avoid browser site attack.</span><br />
<span style="font-size: large;">2>You should install Mozilla Firefox Version 20.0.</span><br />
<span style="font-size: large;">  Now you may ask why Firefox 20.0 ?Why not latest version of Firefox?</span><br />
<span style="font-size: large;">  Because some of the add-ons I use is not available on latest version.</span><br />
<span style="font-size: large;">  Download Mozilla Firefox 20.0 from the link below--</span><br />
<div style="text-align: center;">
<b><i><u><span style="font-size: large;"> </span><a href="http://download.mozilla.org/?product=firefox-20.0.1&os=win&lang=en-US" style="font-size: x-large;" target="_blank">Mozilla Firefox 20.0(Download Link)</a></u></i></b></div>
<span style="font-size: large;"><br /></span><span style="font-size: large;"> By the time you might be installed Firefox,Now its time to add some great add-ons to your Browser.</span><br />
<span style="font-size: large;"> Now open the firefox,left click just above Address Bar And select "Menu Bar".This enable your Menu bar which will</span><br />
<span style="font-size: large;">make it easy to launch any add-ons from the "Tools" menu.</span><br />
