This Python project implements a Caesar Cipher, a type of substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.
- Encoding and Decoding: The program allows users to encode or decode messages using the Caesar Cipher.
- Input Validation: It handles input validation to ensure that only letters are encoded or decoded, while maintaining numbers, symbols, and spaces unchanged.
- Shift Wrapping: If the shift number provided by the user is greater than 26 (the number of letters in the alphabet), it wraps around to continue the shift cycle.
- User Interaction: The program prompts users to enter the direction (encode or decode), the message to be processed, and the shift number.
- Restart Option: After encoding or decoding a message, users can choose whether to restart the program to encode/decode another message.
- Run the Python script (
encryptDecode.py) to start the program. - The program will display the Caesar Cipher logo.
- Enter the direction of the operation: 'encode' to encrypt a message or 'decode' to decrypt a message.
- Enter the message to be encoded or decoded.
- Enter the shift number to determine the amount of shifting for encoding or decoding.
- After the result is displayed, choose whether to restart the program by typing 'yes' or 'no'.
If the user enters a shift number greater than 26 (the number of letters in the alphabet), the program handles this by wrapping around the shift cycle. For example, a shift of 27 would be equivalent to a shift of 1, and a shift of 30 would be equivalent to a shift of 4.
The program imports and displays a logo from encryptDecodeLogo.py at the beginning of execution.
After encoding or decoding a message, the program prompts the user to restart by typing 'yes' to continue encoding/decoding another message or 'no' to exit the program.
