Simple Cipher – Can You Decode the Message?

 

This week’s challenge is for all the security enthusiasts and code breakers out there. Let’s test your skills with a classic encryption concept!

🧩 Challenge: Caesar Cipher Decoder

A Caesar Cipher is a simple encryption technique where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Example:
If the shift is 3, then:

  • A → D

  • B → E

  • C → F
    ... and so on.

Here’s the encrypted message:

🔍 Your Task:

  1. Write a program to decode the message using the Caesar Cipher method.

  2. Assume the shift is unknown – your program should try all possible 25 shifts and display the results.

  3. Identify and print the most readable one (hint: check for common English words like "this", "is", "the"...).

💻 Requirements:

  • Language: Any (Python, JavaScript, Ruby, etc.)

  • Output: All possible decoded messages with their shift number.

🚀 Bonus:

  • Automatically detect the most likely correct shift using a list of English keywords.

  • Add a function to allow the user to input their own encrypted message.


💡 Tip: Use ord() and chr() in Python for quick character shifting.
