WebThe Caesar cipher is a classic example of ancient cryptography and is said to have been used by Julius Caesar. The Caesar cipher is based on transposition and involves shifting each letter of the plaintext message by a certain number of letters, historically three, as shown in Figure 5.1.The ciphertext can be decrypted by applying the same number of … Webpython caesar_ciphyer. This reference program caesar_ciphyer encrypts a given message and then performs decryption. After the caesar_ciphyer program is run, it will display the plaintext, ciphertext, and the decrypted plaintext. If the cipher works correctly, the plain text and decrypted text should be the same.
