Cracking Codes

  1. 1. Cracking Codes A project about codes and how to crack them.
  2. 2. Introduction <ul><li>Codes are symbols representing the alphabet. They can be used for many reasons. Some use them just for fun or to send a private note to a friend that you don’t want anyone else to figure out. But others may use it in war like one of the George Washington codes, at sea like the flag code, or on telegraphs like Morse code. Read more to find out different codes, how to crack them and more! </li></ul>
  3. 3. Code 1 <ul><li>The first code you are going to learn about is the letter code. In this code “A” is lined up with “Z”, “B” is lined up with “Y” and so on. In order to crack this code, like if you were to do “Hi”, the code would read “Sr”. First, you would find “S” and look below it and “H” would be there. Then, do the same with “S” and you’ll find “I”. Put that together and you have “Hi”. Use the chart on the next page to figure out the code beneath it. </li></ul>
  4. 4. Figure This Out!
  5. 5. Code 2 <ul><li>Code two is the number code. In this one, “A” lines up with “1”, “B” lines up with “2” and so on. To crack this code, let’s say you want to say “Hi”, the code would read 8, 10. First you would go to the bottom of the chart and find 8. Then, you’d go up and there is “H”, To find out what the 10 is, you would do what you did with 8. Use the chart on the next page to figure out the code beneath it. </li></ul>
  6. 6. Figure This Out!
  7. 7. Code 3 <ul><li>On to code three. This one is called the color code. Each letter has a different color so there is no certain pattern. Let’s say you wanted to say “Hi”, your code would use the colors light green and red. Find the colors then look above and there is the letter in this case if you used light green there would be a “H” above it. It’s the same concept for red. Find red on the bottom row, look above and there will be an “I”. Use the chart on the next page to figure out the code below it. </li></ul>
  8. 8. Figure This Out!
  9. 9. The Last Three Codes <ul><li>The last three codes were the most basic codes used when having fun or sending a private note. The next two are used at war, and were both used by George Washington. He used both these codes to send secret notes to spy’s or have spy’s send secret notes to other people. </li></ul>
  10. 10. Code 4 <ul><li>The code on the next page is very much like one of George Washington code. It consists on different symbols. He used it probably in the American Revolution to safeguard hid messages. Use the chart on the next page to figure out the code beneath it. </li></ul>
  11. 11. Figure This Out
  12. 12. Code 5 <ul><li>This last code is called the sympathetic stain code. It was another code used by George Washington in the war. This code has two parts. The first part ( on the next page), had “A” line up with “E”, and “B” line up with “F” and so on. The next part used letters. The tricky part with this is that there is no certain pattern. Different set of numbers for a common used word. For instance, camp was 73, and enemy was 178. Use the chart on the next page to figure out the code below it. </li></ul>
  13. 13. Figure This Out!
