Sanic-HTTPAuth

This a fork of Flask-HTTPAuth for Sanic. It is a simple extension that provides Basic and Digest HTTP authentication for Sanic routes.

Still a work in progress, contributions are welcome.

Installation

The easiest way to install this is through pip.

pip install Sanic-HTTPAuth

Basic authentication example

import hashlib
from sanic import Sanic, response
from sanic_httpauth import HTTPBasicAuth

app = Sanic(__name__)
auth = HTTPBasicAuth()


def hash_password(salt, password):
    salted = password + salt
    return hashlib.sha512(salted.encode("utf8")).hexdigest()


app_salt = "APP_SECRET - don't do this in production"
users = {
    "john": hash_password(app_salt, "hello"),
    "susan": hash_password(app_salt, "bye"),
}


@auth.verify_password
def verify_password(username, password):
    if username in users:
        return users.get(username) == hash_password(app_salt, password)
    return False


@app.route("/")
@auth.login_required
def index(request):
    return response.text(f"Hello, {auth.username(request)}!")


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

Note: See the Flask-HTTPAuth documentation for more complex examples that involve password hashing and custom verification callbacks.

Digest authentication example

from sanic import Sanic, response
from sanic_httpauth import HTTPDigestAuth
from sanic_session import Session

app = Sanic(__name__)
app.config["SECRET_KEY"] = "secret key here"
auth = HTTPDigestAuth()
Session(app)

users = {"john": "hello", "susan": "bye"}


@auth.get_password
def get_pw(username):
    if username in users:
        return users.get(username)
    return None


@app.route("/")
@auth.login_required
def index(request):
    return response.text(f"Hello, {auth.username(request)}!")


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