ToneCrypt

ToneCrypt is a Python-based tool that encrypts folders into WAV audio files using pitch shifts, noise, and reverb, with tones encoding decryption keys via a nonlinear equation [cos(f1/200)*f2^3 + log(f3+1)*exp(f2/500) + sin(f1/f3)]. It supports decryption from audio files, microphone recordings, or CDs, with Reed-Solomon error correction for robust folder restoration.

Features

• Audio-Based Encryption: Convert folders or .zip files to WAV files with customizable pitch shifts and noise levels.
• Flexible Decryption: Decrypt from WAV files, microphone input, or CD audio. Supports restoring folders or .zip files.
• Secure Key Derivation: Uses SHA-256 to derive encryption parameters from a user-provided key.
• Error Correction: Implements Reed-Solomon encoding for reliable data recovery.
• Interactive & CLI Modes: Supports both interactive prompts and command-line arguments.

Installation

Option 1: Quick Start (Recommended)

Use a Python virtual environment to keep your system clean:

git clone https://github.com/ewarggg776/tonecrypt.git
cd tonecrypt
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python3 ToneCrypt.py

Option 2: Install via .deb Package

(Best for permanent system-wide usage)

1. Install System Dependencies:

   sudo apt-get update
   sudo apt-get install python3 python3-pip libsndfile1 ffmpeg wodim cdparanoia alsa-utils

2. Build and Install:

   dpkg-deb --build tonecrypt_1.0-1
   sudo dpkg -i tonecrypt_1.0-1.deb

Usage

Interactive Mode (with Color & Verbosity)

Run python3 ToneCrypt.py (or the installed /usr/local/bin/ToneCrypt.py) with no arguments to enter interactive mode:

python3 ToneCrypt.py

Features:

• Colorful, user-friendly prompts
• Toggle verbose/debug output with V at the menu
• Choose encrypt or decrypt, and follow the prompts
• Supports both folders and .zip files for encryption and decryption

Command-Line Mode

You can also use command-line arguments:

# Encrypt a folder:
python3 ToneCrypt.py --mode encrypt --input my_folder --output encrypted.wav --key mysecret --noise 0.1
# Encrypt a .zip file:
python3 ToneCrypt.py --mode encrypt --input my_archive.zip --output encrypted.wav --key mysecret
# Decrypt to a folder:
python3 ToneCrypt.py --mode decrypt --input encrypted.wav --output restored_folder --key mysecret
# Decrypt to a .zip file:
python3 ToneCrypt.py --mode decrypt --input encrypted.wav --output restored.zip --key mysecret

Examples

1. Encrypt a Folder:

   mkdir -p test_folder/subdir
   echo "Hello" > test_folder/test.txt
   echo "World" > test_folder/subdir/subtest.txt
   python3 ToneCrypt.py --mode encrypt --input test_folder --output encrypted.wav --key mysecret

2. Encrypt a .zip File:

   zip -r mydata.zip test_folder
   python3 ToneCrypt.py --mode encrypt --input mydata.zip --output encrypted.wav --key mysecret

3. Decrypt to a Folder:

   python3 ToneCrypt.py --mode decrypt --input encrypted.wav --output restored_folder --key mysecret

4. Decrypt to a .zip File:

   python3 ToneCrypt.py --mode decrypt --input encrypted.wav --output restored.zip --key mysecret
   # Then unzip restored.zip
   unzip restored.zip -d restored_folder

5. Decrypt from Microphone:

   python3 ToneCrypt.py

   Choose decrypt, select mic, and follow prompts.

Troubleshooting

• APT Lock Errors: If you encounter Could not get lock /var/lib/dpkg/lock-frontend:

  sudo rm /var/lib/dpkg/lock-frontend
  sudo dpkg --configure -a
  sudo apt-get install -f

• Command Not Found: Ensure /usr/local/bin is in your PATH:

  echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc
  source ~/.bashrc

• Python Dependency Errors: Reinstall dependencies:

  pip3 install --break-system-packages numpy scipy soundfile librosa reedsolo colorama pydub
