Explanation:
Detailed explanation-1: -A Caesar cipher is a simple method of encoding messages. Caesar ciphers use a substitution method where letters in the alphabet are shifted by some fixed number of spaces to yield an encoding alphabet. A Caesar cipher with a shift of 1 would encode an A as a B, an M as an N, and a Z as an A, and so on.
Detailed explanation-2: -An old simplistic trick is the Caesar cipher. Pick a key from 1 and 25; then for each character in your message, shift each letter forward by the key, wrapping around the end of the alphabet. For example, if your original message is “helloyou", and your key is 2, your encrypted message is “jgnnqaqw".
