FlaskSecureKeyGen 0.1.0

A library to generate secure random secret keys for Flask apps.

FlaskSecureKeyGen

FlaskSecureKeyGen is a Python library designed to generate secure, random secret keys for Flask applications. It ensures that your Flask app's secret keys are cryptographically strong and suitable for production use.

Installation

You can install FlaskSecureKeyGen using pip:

pip install FlaskSecureKeyGen

Usage

1. Generating a Secret Key

The main functionality of this library is to generate secure secret keys. You can use the generate_secret_key function from the keygen module.

from flask_secure_keygen import generate_secret_key

# Generate a 64-character secret key
secret_key = generate_secret_key(64)
print(secret_key)

Parameters:

• length: The length of the secret key (default is 64). Must be at least 32 characters for security.

Example Output:

3a1f8e4d7c9b2a5f6e8c9d0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0

2. Using Utility Functions

The library also provides utility functions in the utils module to help validate key lengths.

from flask_secure_keygen.utils import validate_key_length

# Check if a key length is valid
is_valid = validate_key_length(40)
print(is_valid)  # Output: True

Parameters:

• length: The desired key length to validate.

Returns:

• True if the length is valid (i.e., 32 or more characters).
• False otherwise.

3. Integrating with Flask

You can use the generated secret key directly in your Flask application.

from flask import Flask
from flask_secure_keygen import generate_secret_key

app = Flask(__name__)

# Generate and set a secure secret key for the Flask app
app.secret_key = generate_secret_key(64)

@app.route('/')
def home():
    return "Hello, Flask!"

if __name__ == "__main__":
    app.run(debug=True)

Why Use FlaskSecureKeyGen?

• Secure: Uses Python's secrets module to generate cryptographically strong random keys.
• Simple: Just one function to generate keys of any length (minimum 32 characters).
• Customizable: You can specify the length of the key as per your requirements.
• Utility Functions: Additional utility functions to validate key lengths.
