Explanation:
Detailed explanation-1: -With a shift of 3, every letter is replaced by the letter 3 letters to its right. Letters at the end of the alphabet wrap around to the beginning (e.g. ‘z’ shifted by 3 becomes ‘c’).
Detailed explanation-2: -The Caesar cipher uses shift-by-3 rule for its encryption and decryption. However, the newly-developed algorithm uses keys between 0 and 25; it employs three different keys, one for each encryptionphase.
Detailed explanation-3: -Choose a value to shift the alphabet by. Make a table where the top row contains letters in standard alphabetical order, and the bottom row is the new shifted alphabet. Encode the message by exchanging each letter in the message with the equivalent shifted letter. More items
