Display memory in hexa:

Encrypter/decrypter of mesage:
def encrypt(message, shift): encrypted_message = "" for char in message: if char.isalpha(): offset = ord('A') if char.isupper() else ord('a') encrypted_char = chr((ord(char) - offset + shift) % 26 + offset) encrypted_message += encrypted_char else: encrypted_message += char return encrypted_message def decrypt(encrypted_message, shift): return encrypt(encrypted_message, -shift) # Example usage: original_message = "Hello, World!" shift_amount = 3 # Encrypt the message encrypted_message = encrypt(original_message, shift_amount) print(f"Encrypted: {encrypted_message}") # Decrypt the message decrypted_message = decrypt(encrypted_message, shift_amount) print(f"Decrypted: {decrypted_message}")
