The encryption method I’ll demonstrate is a simple letter shift cipher, where each letter of the alphabet is replaced by another letter.

A letter shift cipher is known as “Caesar’s cipher,” named for Julius Caesar, who was the first recorded person to use it.

My example will remind older readers of the code card they received when they joined the “Supermen of America” club from the back of Superman and Action Comics magazines.
