Phantom Wave is a desktop application written in Python that allows you to hide secret messages within WAV audio files using the Least Significant Bit (LSB) steganography method combined with AES encryption for enhanced security.

• Hide messages: Embed secret messages into WAV audio files.
• Extract messages: Retrieve hidden messages from WAV audio files.
• AES encryption: Messages are encrypted using AES (Advanced Encryption Standard) in CBC (Cipher Block Chaining) mode before being hidden, ensuring confidentiality.
• Key management: Generate and load AES encryption keys.
• User-friendly GUI: A simple graphical user interface built with Tkinter for ease of use.

• Python 3.x
• scipy
• numpy
• pycryptodome
• You can use the requirements.txt file to install all the needed libraries by navigating to the project's directory and running:

pip install -r requirements.txt

Run the app

1. Download the files.
2. Navigate to the directory containing the Python files.
3. Run the main_wav.py script:

   python main_wav.py
   

To Hide a Message:

1. Select WAV file: Click "Select WAV file" and choose a "clean" (original) WAV audio file.
2. Enter your secret message: Type the message you want to hide in the text box.
3. Generate or Load AES key:
   • If you don't have a key, click "Generate AES key" to create a new one. It will be saved as audio_key.key.
   • If you have an existing key, click "Load AES key" and select your .key file.
4. Hide message: Click "Hide message". You will be prompted to save the new WAV file containing the hidden message.

To Extract a Message:

1. Select WAV file: Click "Select WAV file" and choose the WAV file that contains a hidden message.
2. Load AES key: Click "Load AES key" and select the exact same key that was used to hide the message.
3. Extract message: Click "Extract message". The extracted message will be displayed in a pop-up window.
