The Caesar Cipher is one of the simplest and oldest encryption techniques. It is a type of substitution cipher where each letter in the plaintext is shifted by a certain number of positions down or up the alphabet. Though it's not secure for modern use, it is widely used in introductory cryptography lessons.
We implement the Caesar Cipher to encrypt and decrypt messages. The user can input a message and a shift value (between 0 and 25), and the program will either encrypt or decrypt the message based on their choice.
Encryption:
The process of converting plaintext (readable message) into ciphertext (encoded message) using a specific algorithm and key (shift value).
Decryption:
The process of converting the ciphertext (encoded message) back into its original form (plaintext) using the same key (shift value).
