=====One-Time Pad Example=====

Figure 27 contains an excerpt form the ''Rubaiyat of Omar Khayyam'' and the word AWAKE is the first word in the ''Rubaiyat''.  Assuming we have the encoded message AFM and we want to use the second letter position to decode it.  The program will search the ''Rubaiyat'' from beginning to end, until it finds the first word that begins with A. From Figure 27, the word should be AWAKE. This will then be decoded to the second letter in the same word which is W.  The program will repeat step 2 for the rest of the letters in the code. The second word and third word should be FOR and MORNING based on the ''Rubaiyat of Omar Khayyam''.  The output should be WOO.  Figure 28 shows the output from MATLAB, the function called multi, which shows all possible decoded messages according to letter position n. For example, if n equals 2, the output will display the first original encoded message AFM and the second decoded message WOO as well.
