-aiohttp-basicauth-middleware
-============================
-
-.. figure:: https://travis-ci.org/bugov/aiohttp-basicauth-middleware.svg?branch=master
-
-
-Aiohttp middleware for simple http basic
-auth protection for some urls.
-
-Works with Python >= 3.6.
-
-Works with UTF-8 🖖
-
-Installation
-------------
-
-.. code:: bash
-
-    pip install aiohttp-basicauth-middleware
-
-Usage
------
-
-.. code:: python
-
-    app = web.Application(loop=loop)
-
-    app.router.add_route('GET', '/hello', handler_a)
-    app.router.add_route('GET', '/admin/hello', handler_b)
-
-    app.middlewares.append(
-        basic_auth_middleware(
-            ('/admin',),
-            {'user': 'password'},
-        )
-    )
-
-
-`basic_auth_middleware` has 3 params:
-
-1. list of protected urls. For example `['/admin']` will match
-   with `/admin/user`, but will not match with `/user/admin`.
-2. auth dict – a dict with pairs: login-password.
-3. strategy (optional) for password comparision. For example you can
-   store hashed password in `auth_dict`. See `aiohttp_basicauth_middleware.strategy.BaseStrategy` and
-   `example.strategy` for more information.
-
-Example with md5 password hashing:
-
-.. code:: python
-
-    app = web.Application(loop=loop)
-
-    app.router.add_route('GET', '/hello', handler_a)
-    app.router.add_route('GET', '/admin/hello', handler_b)
-
-    app.middlewares.append(
-        basic_auth_middleware(
-            ('/admin',),
-            {'user': '5f4dcc3b5aa765d61d8327deb882cf99'},
-            lambda x: hashlib.md5(bytes(x, encoding='utf-8')).hexdigest(),
-        )
-    )
-
-`/admin/...` will be accessed by the same login+password pair ('user', 'password').
