Explanation:
Detailed explanation-1: -Cryptography is the process of converting between readable text, called plaintext, and an unreadable form, called ciphertext . This occurs as follows: The sender converts the plaintext message to ciphertext. This part of the process is called encryption (sometimes encipherment ).
Detailed explanation-2: -The Caesar Cipher is a monoalphabetic rotation cipher used by Gaius Julius Caesar. Caesar rotated each letter of the plaintext forward three times to encrypt, so that A became D, B became E, etc., as shown in Table 4.6.
Detailed explanation-3: -Decryption, the inverse of encryption, is the process of turning ciphertext into readable plaintext.
