The Caesar cipher is a simple and widely known encryption technique. It works by shifting each letter in the plaintext by a fixed number of positions down or up the alphabet.
This Python program allows you to encrypt and decrypt messages using the Caesar cipher with a specified key.
- Encryption: Transform plain text into a Caesar cipher with a specified key.
- Decryption: Reverse the Caesar cipher to reveal the original plain text.
- Shifts: Choose any integer value from 1 to 26 for shifting the characters.
-
Run the program:
python caesar_cipher.py -
Select 'e' for encryption or 'd' for decryption.
-
Enter the shift key (1-26).
-
Input the text you want to process.
-
The program will display the encrypted or decrypted text.
- Input:
e - Shift Key:
3 - Text:
hello, world! - Output:
khoor, zruog!
- Input:
d - Shift Key:
3 - Text:
khoor, zruog! - Output:
hello, world!
