a. Develop a Caesar cipher type encryption algorithm with a little more complexity in it. For example, the algorithm could alternatively shift the clear text letters positive and negative by the amount of the key value. Variations on this are limitless.

b. Select a single digit key.

c. Code a short message using the algorithm and key.

d. Give your instructor the algorithm, key, clear text, and cipher text.

e. Optional: Your instructor will randomly redistribute to the class the cipher text messages completed in part d above. You are to decode the message you receive as an additional assignment.
