CAN SOMEONE PLEASE HELP ME CREATE THIS. THANK YOU!

a. Develop a Caesar cipher-type encryption algorithm with a little more complexity in it. For example, the algorithm could alternatively shift the cleartext 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. (Message should read "GOOD MORNING PROFESSOR")

d. Give your instructor the algorithm, key, cleartext, and ciphertext.
