This page will give you the required knowledge you need to have to break my codes in the next page. Hope you enjoy this little game ! CAESAR'S BOX The first type of code used is a Caesar�s box. This code was used by Julius Caesar to send messages to his troops. It is a string of seemingly random letters. To be a Caesar�s Box ,the number of letters has to be a square. Such as 9,16,25,36 etc., to enable you to form a box from the letters. As an example the string of letters STDEHOEEG, is nine letters. This will form a box three across and three down. The letters are written as follows, S T D E H O E E G and the message is read top to bottom by column, or SEE THE DOG. A string of 64 letters would produce a box 8 letters by 8 letters. When you are given a string of letters count to see if the number of letters is a square, and if so decipher using the Caesar�s Box. SUBSTITUTION CIPHER A Cryptogram is a puzzle in which each letter in a sentence is replaced by a different letter of the alphabet. The letters in the cryptogram are called �cipher� letters, and the letters that you will write down are called �plain� letters.The next type of code is the letter for letter substitution. This is the type of code where each letter is assigned a numeric value, A=1, B=2, C=3, etc. Then using a �key� number you are given, you will substitute the given number, for the real number. Example if the code is 5, then A=E, B=F, C=G, D=H, E=I, F=J, G=K, H=L, I=M, J=N, K=O, L=P, M=Q, N=R, O=S, P=T, Q=U, R=V, S=W, T=X, U=Y,V=Z, W=A, X=B, Y=C, Z=D. So in code 5, the string of letters WII XLI HSK = SEE THE DOG. These two codes can be combined. If the letter string is a square, but does not make sense in the Caesar�s box, then you will need the code to substitute the letters into the box. There are many more types of codes, however these are the only two types of code breaking techniques you require to break my codes.Please go to the Practice Page to practice with some of the easier codes before trying to attempt solving the main codes.
