PDF Secure is a desktop and command-line application that encrypts and decrypts PDF files with an extra layer of IP-based security. Only authorized IP addresses can access the protected documents.
- Encrypt and decrypt PDF files using symmetric encryption (Fernet/AES).
- IP whitelisting: only specific IPs can decrypt the file.
- User-friendly graphical interface (Tkinter).
- Command-line interface (CLI) included.
- Manageable whitelist of IPs.
- Cross-platform: works on Windows, Linux, and macOS.
- Python 3.8 or higher
- Packages:
cryptography,tkinter(usually included with Python)
Install the required packages with:
#pip install cryptography
🚀 Installation Clone the repository: #git clone https://github.com/zeligmax/proyecto_pdf_seguro.git #cd proyecto_pdf_seguro
🖥️ GUI Usage Run the GUI with: #python app/app_gui.py
From the interface, you can:
Encrypt a PDF file.
Decrypt a .enc file.
Add or remove IPs from the whitelist.
🧪 CLI Usage Run the app in the terminal: #python app/main.py
Then follow the prompts:
Option 1: Encrypt a PDF
Option 2: Decrypt a protected file
🔐 IP-Based Access Control When encrypting a PDF, a list of authorized IPs is embedded. Only those IPs can decrypt the file, preventing unauthorized distribution.
You can manage the whitelist via the GUI or by editing config.py directly.
