I NEED A MATHEMATICAL ALGORITHM FOR A CEASER CHYPER I CREATED. PLEASE HELP ME...THANK YOU!

THE SINGLE-DIGIT KEY IS 14

THE PHRASE IS "GOOD MORNING PROFESSOR"

THE CYPHER IS UCCR ACFBWBU DFCTSGGCF

I DON'T KNOW HOW TO CREATE THE ALGORITHM AND IT CANNOT BE COMPUTER GENERATED.

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.

14

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