    encrypt_and_destroy()

• The encrypt_and_destroy() function first prompts the user to select a folder to encrypt.

• The function then prompts the user to enter a password to encrypt the folder.

• The function then hashes the password using the SHA-512 algorithm and stores the hash in a variable.

• The function then prompts the user to re-enter the password.

• The function then compares the two passwords. If the passwords do not match, the function prints an error message and returns.

• If the passwords match, the function decompresses and decrypts the file.

• The function then prints a message stating that the file has been successfully decrypted.

• The if name == "main": statement ensures that the encrypt_and_destroy() function is only executed when the file is run as a script.

• A filedialog.askdirectory() function was added to the encrypt_and_destroy() function. This function opens a file selection dialogue box and allows the user to select the folder they want to encrypt.

• The input_folder variable was changed to a global variable. This was done so that the encrypt_and_destroy() function can access the value of the input_folder variable.
