LockFly

LockFly is a simple secure file transfer application designed to facilitate the secure and encrypted transfer of files between devices. Leveraging Python's cryptography library, LockFly ensures data remains confidential and protected during transit.

Features

• Secure File Transfer: Utilizes symmetric encryption (Fernet) from the cryptography library for data protection.
• User-Friendly Interface: Command-line interface with interactive prompts and progress bars for user confirmation.
• Cross-Platform Compatibility: Designed to run on both Unix-based systems and Windows.
• Easy Setup: Automated setup scripts to simplify the installation and execution process.
• Disk Space Check: Ensures there is enough disk space before starting the file transfer to avoid any crashes.

Prerequisites

• Python 3.x

Setup and Usage

1. Clone the repository:

   git clone https://github.com/CloudyKhan/lockfly.git
   cd lockfly

2. Install dependencies:

   You can install the dependencies manually using pip:

   pip install -r requirements.txt

   Or, you can use the provided setup script:

   Unix-based Systems

   chmod +x setup.sh
   ./setup.sh

   Windows

   setup.bat

3. Run the Application

   python lockfly.py

4. Follow the interactive prompts to send or receive files.

Encryption Details

LockFly employs symmetric encryption using the Fernet module from the cryptography library. Fernet uses AES in CBC mode with a 128-bit key for encryption and HMAC for authentication. This ensures that files are encrypted with a key derived from a password provided by the user, ensuring that only users with the correct password can decrypt and access the transferred files.
