PyCriptoNita

PyCriptoNita is a simple Python script designed to encrypt and decrypt text messages using a randomly generated substitution cipher.

How it works:

1. Key Generation: A unique key is created by randomly shuffling all possible characters (letters, digits, punctuation, and special characters).
2. Encryption: Each character in the input message is replaced with the corresponding character in the key, shifted by one position to the right.
3. Decryption: The encrypted message is decrypted by reversing the encryption process, shifting each character in the encrypted message one position to the left.

Usage:

1. Run the script: Execute the main.py file.
2. Enter your message: The script will prompt you to input the message you want to encrypt or decrypt.
3. View the result: The encrypted or decrypted message will be displayed on the console.

Example:

Enter your message: Hello, world!

Encrypted message: Ifmmpx, yxovl!

Note:

• The security of this encryption method is limited.
• The script assumes that the same key is used for both encryption and decryption. In a real-world application, the key should be securely distributed to authorized parties.

Future enhancements:

• Implement different encryption algorithms.
• Allow users to choose the key.
• Provide options for saving and loading encrypted messages.
• Add a graphical user interface for easier interaction.
