4. Dependencies

• Flask
• Crypto (pycryptodome)

Install dependencies using: pip install -r requirements.txt

5. Configuration

• Update configurations in the respective files if needed.

6. Authentication

• The auth.py module handles user authentication using username, account number, phone number, and password.
• User authentication is done through the Flask web interface (main.py).
• The password is same as phone number.

7. Encryption

• Encryption of sensitive data is implemented in the encryption.py module using the DES algorithm.
• Keys are generated dynamically for each transaction.

8. Consistency Checks

• Consistency checks are performed in the consistency_checks.py module.
• Checks include verifying unique transaction IDs, different sender and recipient accounts, and sufficient funds.

9. Database

• The database.py module manages user accounts and transactions.
• It loads and saves data to CSV files (accounts.csv and transactions.csv).

10. Verification

• The verification.py module is responsible for verifying transfer requests.
• It checks the validity of the sender and recipient accounts, transaction amount, and other details.

11. Web Interface

• The web interface is implemented using Flask in main.py.
• HTML templates are stored in the templates directory.
