📦 Installation

# Desktop / PC / Mac
pip install pyprotectorx

# Termux (Android)
pkg install python
pip install pyprotectorx

# Pydroid3 (Android)
# Menu → Pip → Search: pyprotectorx → Install

🎯 Quick Start

Command Line (Easiest)

# Protect any Python file
pyprotectorx script.py

# Run protected file
python script.protected.py

Python API

from pyprotectorx import protect

# Protect file
protect("script.py")
# Output: script.protected.py

Advanced API

from pyprotectorx import encrypt, run

# Encrypt code
source = 'print("Hello, World!")'
encrypted = encrypt(source)

# Run encrypted code
run(encrypted)

📖 Complete Examples

Example 1: Basic Usage

# Create test script
echo 'print("Secret Code!")' > test.py

# Protect it
pyprotectorx test.py

# Run protected version
python test.protected.py
# Output: Secret Code!

Example 2: Termux

# Install
pkg install python -y
pip install pyprotectorx

# Protect your script
cd ~/storage/shared
pyprotectorx myapp.py

# Share the protected file
python myapp.protected.py

Example 3: Pydroid3

from pyprotectorx import protect

# Protect file
protect("/sdcard/Download/script.py")

# Output: /sdcard/Download/script.protected.py

🔥 API Reference

protect(input_file, output_file=None)

Easiest method - Protect a Python file

from pyprotectorx import protect

protect("app.py")  # → app.protected.py
protect("app.py", "secure.py")  # → secure.py

encrypt(source_code)

Encrypt Python source code

from pyprotectorx import encrypt

encrypted = encrypt('print("Hi")')
# Returns: bytes

run(encrypted_data)

Execute encrypted code

from pyprotectorx import run

namespace = run(encrypted_data)
# Returns: dict with execution namespace

info()

Show version information

from pyprotectorx import info

print(info())
# {'version': '5.5.0', 'python': '3.12.0', ...}

📱 Mobile Development Tips

Termux Best Practices

# Storage access
termux-setup-storage

# Work in shared storage
cd ~/storage/shared

# Protect scripts
pyprotectorx script.py

Pydroid3 Tips

# Use full paths
from pyprotectorx import protect

# Protect file in Downloads
protect("/sdcard/Download/app.py")

# Protect file in Documents
protect("/sdcard/Documents/script.py")

⚠️ Requirements & Limitations

Requirements

• Python 3.11, 3.12, or 3.13
• No additional dependencies

Limitations

• Maximum file size: 100 MB
• Source code must have valid syntax
• Python 3.14+ not yet supported

Compatibility

✅ Linux, macOS, Windows
✅ Termux (Android)
✅ Pydroid3 (Android)
✅ Raspberry Pi
✅ Cloud environments

🐛 Troubleshooting

Error: "Python 3.11+ required"

# Check Python version
python --version

# Termux: Install Python 3.11+
pkg install python

# Pydroid3: Update app to latest version

Error: "Failed to load core"

# Reinstall package
pip uninstall pyprotectorx -y
pip install --no-cache-dir pyprotectorx

Error: "Syntax error in source"

# Validate your script first
python -m py_compile script.py

Protected file too large

# Use direct encryption API
from pyprotectorx import encrypt
import base64

encrypted = encrypt(source_code)
# Store encrypted bytes separately
with open('data.bin', 'wb') as f:
    f.write(encrypted)

🔒 Security Notice

⚠️ Important: No encryption is unbreakable. PyProtectorX makes reverse engineering significantly harder but cannot guarantee absolute protection against determined attackers with unlimited resources.

Good for:

• ✅ Protecting proprietary algorithms
• ✅ Preventing casual code inspection
• ✅ Obfuscating business logic
• ✅ License key protection
• ✅ Anti-tampering measures

Not a substitute for:

• ❌ Proper authentication systems
• ❌ Secure password storage
• ❌ Network security
• ❌ Server-side validation
