This Python program implements the Caesar Cipher, a simple substitution cipher where each letter in the plaintext is shifted a certain number of places down the alphabet. How to Use: Run the program: Execute the Python script. Choose encryption/decryption: Select "encode" to encrypt or "decode...

At this stage, we have understood the encryption and decryption process of the Caesar Cipher, and have implemented the same in Python. Now we will look at how it can be made more efficient and more flexible. Specifically, we’ll focus on how we can avoid the repeated computations of the ...
The decryption method used in the code isa form of brute-force attack.A brute-force attack is a cryptographic attack method that involves trying all possible combinations of keys to decrypt an encrypted message. In this case, the code tries all possible shift keys for the Caesar cipher, which...
