Python File Protector - Enhanced Documentation

Comprehensive Application Description

Python File Protector is a robust security application designed to safeguard your Python source code files (.py) through advanced encryption and access control mechanisms. This tool provides multiple layers of protection to prevent unauthorized access, modification, or theft of your intellectual property.

Key Security Features

• Military-grade AES-256 encryption for file protection
• Password-based access control with configurable complexity requirements
• File integrity verification using SHA-256 hashing
• Multi-platform compatibility (Windows, macOS, Linux)
• Secure deletion of original files after encryption
• Tamper-evident design that detects modification attempts

System Requirements

Minimum Requirements

• OS: Windows 7/10/11, macOS 10.15+, or Linux with GTK
• Processor: 1.5 GHz dual-core
• Memory: 2 GB RAM
• Storage: 50 MB available space
• Python: 3.8+ (bundled in executable version)

Recommended Requirements

• OS: Windows 10/11, macOS 12+, or Ubuntu 20.04+
• Processor: 2.4 GHz quad-core
• Memory: 4 GB RAM
• Storage: 100 MB SSD
• Python: 3.10+ (for source version)

Detailed Usage Guide

1. Application Launch

• Executable Version: Double-click protector.exe (Windows) or protector.app (macOS)
• Source Version: Run python protector.py in terminal

2. File Selection Interface

• Click Browse to select a Python file (.py)
• Supported file indicators:
  • ✅ Valid Python files show green highlight
  • ❌ Invalid files show red warning
• File details panel displays:
  • File size
  • Last modified date
  • Line count estimate
  • SHA-256 checksum

3. File Protection Options

# Sample encryption configuration
config = {
    "algorithm": "AES-256-CBC",
    "key_derivation": "PBKDF2-HMAC-SHA256",
    "iterations": 100000,
    "salt_size": 16,
    "iv_size": 16,
    "block_size": 64
}

Locking Process:

1. Select encryption strength:

   • Standard (AES-128)
   • Strong (AES-256) - Recommended
   • Maximum (AES-256 with double encryption)

2. Set password requirements:

   • Minimum 12 characters
   • Require mixed case
   • Require numbers/symbols

3. Advanced options:

   • Shred original file (7-pass DoD standard)
   • Add digital signature
   • Create recovery certificate

4. Click Lock to encrypt

4. File Recovery Process

1. Select encrypted file (.pye extension)
2. Enter password (show/hide toggle available)
3. Options:
   • Restore to original location
   • Save to new location
   • Verify file integrity before opening
4. Click Unlock to decrypt

Frequently Asked Questions

Q: Can I recover files if I forget my password?
A: No, the encryption is designed to be irreversible without the password. We recommend using our password hint system or storing recovery keys securely.

Q: How does this compare to pyc compilation?
A: Unlike pyc files which can be decompiled, our encryption provides true security. See our benchmark:

Method	Decompilation Risk	Size Overhead	Performance Impact
.pyc	High	0%	None
.pye	Impossible	15-20%	<5% decryption time

Q: Can I automate this in CI/CD pipelines?
A: Yes! Use our command-line interface:

python protector.py --lock --input script.py --output secured.pye --pass "YourStrongPassword"
