🚀 Installation & Quickstart

🔧 1. Install Dependencies

pip install -r requirements.txt

🔑 2. Generate Encryption Keys

SecureCrypt simplifies the key generation process. Run the following command:

def generate_keys():
    private_key = RSA.generate(4096)
    private_key.save('private.pem')
    public_key = private_key.publickey()
    public_key.save('public.pem')

generate_keys()

🔐 3. Encrypt a File via CLI

Encrypt files easily using the following command:

python main.py --encrypt --file secret.txt --key public.pem

🔓 4. Decrypt Data

Decrypt an encrypted file:

python main.py --decrypt --file secret.enc --key private.pem

🖥️ 5. Launch the Graphical User Interface (GUI)

To launch the GUI, run:

python main.py --gui

Note: Ensure tkinter is installed. For installation instructions, refer to the Tkinter documentation.

🛠 6. Customize Security Settings via config.json

Modify SecureCrypt’s settings by editing the config.json file. Example:

{
  "security": {
    "hsm_enabled": true,
    "key_rotation_interval_days": 30
  },
  "logging": {
    "level": "INFO",
    "retention_days": 90
  }
}

🏆 Best Practices for Maximum Security

🔒 Enable HSM for Secure Key Storage – Utilize hardware-backed key management for an added layer of security.
🔏 Use Strong Passphrases – Always choose a strong passphrase with a minimum length of 16 characters.
🔄 Rotate Keys Regularly – Periodically update keys to prevent long-term cryptographic vulnerabilities.
🛡 Restrict Log Access – Store encrypted logs in secure environments to prevent unauthorized access.

Example Configuration for Enhanced Security

{
  "security": {
    "hsm_enabled": true,
    "key_rotation_interval_days": 30
  },
  "logging": {
    "level": "INFO",
    "retention_days": 90
  }
}
