A Visual Cryptography Generator that takes text as input and encrypts it using a (2,2) visual cryptography scheme.

Installation

1. Clone the repository:

git clone https://github.com/your-username/project-name.git

2. Navigate to the project directory:

cd project-name

3. Create a virtual environment (optional but recommended):

python -m venv venv

4. Activate the virtual environment:

On Unix-based systems:

source venv/bin/activate

On Windows:

venv\Scripts\activate

5. Install the required packages using pip and the requirements.txt file:

pip install -r requirements.txt

This will install all the necessary dependencies for the project.

Usage

To run the main file of the project, execute the following command:

python main.py <text> <private_key>

• <text> (optional): The text to encrypt (up to 10 characters). If not specified, it will prompt for user input.
• <private_key> (optional): The private key filename. If not specified, it will default to default.png.

For example, to encrypt the word "hello" using the private key file secret_1.png, you would run:

python main.py hello secret_1.png

If you omit the arguments, it will prompt you to enter the text and the private key filename in the terminal:

python main.py
