This is a collaborative project developed by my self and Zindine-my class teammate-, focusing on cryptography fundamentals and secure message encoding/decoding. The main goal of this project is to explore how data can be encrypted and hidden using visual techniques and Python programming.
The program is a modern GUI application for encoding and decoding messages using colored dot patterns. This application allows you to encrypt text messages into a visual representation where each character is represented by a unique pattern of colored dots.
(Add your own screenshot here)
- Message Encryption: Convert text into colored dot patterns
- Message Decryption: Convert dot patterns back to readable text
- Modern UI: Clean, dark-themed interface using customtkinter
- File Operations: Load and save encrypted images
- Real-time Status Updates: View operation status in the footer bar
- Python 3.8 or higher
- PIL (Pillow)
- customtkinter
-
Clone the repository:
git clone https://github.com/username/dot-cryptography.git cd dot-cryptography -
Install required packages:
pip install pillow customtkinter
-
Run the application:
python crypto_app.py
- Enter your message in the text box on the left panel
- Click "Encrypt Message"
- The encrypted image will appear in the main panel
- Use "Save Image" to save the encrypted image to a file
- Load an encrypted image using "Load Image" or encrypt a message first
- Click "Decrypt Image"
- The decrypted message will appear in the text box at the bottom
The encryption system uses a grid of colored dots to represent each character:
- Each character is encoded as a 3×3 grid of colored dots
- The application uses 6 colors: Black, White, Gray, Green, Blue, and Red
- Some positions in the grid may be empty (using the background color)
- Each character has a unique pattern, making the code decipherable
The algorithm converts each character to its corresponding dot pattern and arranges these patterns in rows to form the complete encrypted message.

- BLACK: (0, 0, 0)
- WHITE: (255, 255, 255)
- GRAY: (128, 128, 128)
- GREEN: (0, 255, 0)
- BLUE: (0, 0, 255)
- RED: (255, 0, 0)
- Background: (200, 200, 200)
- DOT_SIZE: 10 pixels
- GRID_WIDTH: 3 dots
- GRID_HEIGHT: 3 dots
- GRID_SPACING: 5 pixels between dots
- CHAR_SPACING: 20 pixels between character grids
- ROW_SPACING: 10 pixels between rows
- Fuzzy Color Matching: The decryption algorithm can handle slight color variations due to image compression or editing
- Pattern Recognition: Uses pattern matching to identify characters even when exact matches aren't found
- Error Handling: Gracefully handles invalid characters and file operations
