Flask extension for providing basic digest and token authentication via apache htpasswd files. So largely it fits between Flask-Security <https://pythonhosted.org/Flask-Security/>_ which has additional dependencies and Flask-BasicAuth <http://flask-basicauth.readthedocs.org/en/latest/>_ which only allows you to have one user (and also puts the plain text password into the configuration).

Sample usage is to first create an htpasswd file with the apache tool <http://httpd.apache.org/docs/2.2/programs/htpasswd.html>_:

.. code-block:: bash

htpasswd -c /path/to/.htpasswd my_username

Additional users can be added, or have their passwords changed, by running:

.. code-block:: bash

htpasswd /path/to/.htpasswd new_user htpasswd /path/to/.htpasswd user_I_want_to_change_passwords_for

Then you just need to setup and configure your flask application, with something like:

.. code-block:: python

import flask from flask_htpasswd import HtPasswdAuth

app = flask.Flask(name) app.config['FLASK_HTPASSWD_PATH'] = '/path/to/.htpasswd' app.config['FLASK_SECRET'] = 'Hey Hey Kids, secure me!'

htpasswd = HtPasswdAuth(app)

@app.route('/') @htpasswd.required def index(user): return 'Hello {user}'.format(user=user)

app.run(debug=True)

And that view should now prompt for a username and password (and accept tokens).

If you would like to protect all of your views, that is easy too, just add a little config. By setting app.config['FLASK_AUTH_ALL']=True before initializing the extension, an @app.before_request is added that will require auth for all pages, and it will add the user as flask.g.user.

One last small feature, is that you can also set the authentication realm. The default is 'Login Required', but it can be set with app.config['FLASK_AUTH_REALM'] before initialization.

Using Tokens

Tokens are based on the username and password, and thus invalid whenever the user's password is changed. To get a user password, you can serve it out to the user with something like

.. code-block:: python

import flask from flask_htpasswd import HtPasswdAuth

app = flask.Flask(name) app.config['FLASK_HTPASSWD_PATH'] = '/path/to/.htpasswd' app.config['FLASK_SECRET'] = 'Hey Hey Kids, secure me!' htpasswd = HtPasswdAuth(app)

@app.route('/') @htpasswd.required def index(user): return flask.jsonify({'token': htpasswd.generate_token(user)})

app.run(debug=True)

It can then be used by the user by adding it to the header of their requests, something like:

.. code-block:: python

import requests

requests.get('http://localhost:5000/', headers={'Authorization': 'token '})
