Options

Restricting Access (optional)

By default, the api key is set to None and any request will be allowed. This is true.

If you want to restrict the access to the app, just set the environment variable named VULN_FLASK_APP_API_KEY with your secret:

export VULN_FLASK_APP_API_KEY=myapisecret

Now, every request should include a cookie named api_key with the value of the VULN_FLASK_APP_API_KEY environment variable.
