Sample text

So read through the ciphertext several times, and be prepared to keep finding instances popping out at you! For more hints on how to crack substitution ciphers, read the later section about letter frequency analysis. Caesar / Shift Ciphers A Caesar / Shift Cipher was widely used by the Roman emperor Julius Caesar. Chapter 7 is the place to go for these puzzles. With a Caesar / Shift Cipher, all the letters in the alphabet are shifted by a set amount (such as +5, or –2). To create a Caesar / Shift Cipher, you write the cipher alphabet in order under the plain alphabet, wrapping it around from Z to A until all letters are assigned.

Obviously, the first two words indicate that the correct message is READ THIS BOOK, because READ THIS COOL doesn’t make sense. (Or does it? ) Use your cellphone to help crack these codes. Start a new text message (that you won’t send to anyone), and type in the numbers to see which words are options. Chapter 2: Simplifying Codes and Cryptograms 33 Be careful, though — the phone’s dictionary is very limited. Foreign words, unusual words, and proper nouns generally aren’t included. Typewriter Ciphers Humans have a long history of using “code machines” to physically create a cipher.

Any cipher word that’s in the pattern 1 - - 1 is almost definitely THAT (see, the T appears twice). Check out dictionaries of pattern words (The Cryptogram Dictionary by Lloyd MacCallum is one you may like). These useful books can tell you all the words that fit the 1 2 2 1 pattern, for example (ASSAY, DEEDS, KOOKY, TEETH, and TOOTH, just in case you were wondering). The numbers represent the repeating letters. Chapter 2: Simplifying Codes and Cryptograms 45 With practice you’ll pick up some of the more common pattern words, like PEOPLE (1 2 - 1 - 2), SELLS (1 - 2 2 1), ELEVEN (1 - 1 - 1 -), and ILLEGALLY (- 1 1 - - - 1 1 -).
