API key permissions for the Django REST Framework

Project description

Django REST Framework API Key

API key permissions for the Django REST Framework.

python versions django versions drf versions

Introduction

Django REST Framework API Key is a library for allowing server-side clients to safely use your API. These clients are typically third-party backends and services (i.e. machines) which do not have a user account but still need to interact with your API in a secure way.

Features

  • ✌️ Simple to use: create, view and revoke API keys via the admin site, or use built-in helpers to create API keys programmatically.
  • 🔒 As secure as possible: API keys are treated with the same level of care than user passwords. They are hashed using the default password hasher before being stored in the database, and only visible at creation.
  • 🎨 Customizable: satisfy specific business requirements by building your own customized API key models, permission classes and admin panels.

Should I use API keys?

There are important security aspects you need to consider before switching to an API key access control scheme. We've listed some of these in Security caveats, including serving your API over HTTPS.

Besides, see Why and when to use API keys for hints on whether API keys can fit your use case.

API keys are ideal in the following situations:

  • Blocking anonymous traffic.
  • Implementing API key-based throttling. (Note that Django REST Framework already has may built-in utilities for this use case.)
  • Identifying usage patterns by logging request information along with the API key.

They can also present enough security for authorizing internal services, such as your API server and an internal frontend application.

Please note that this package is NOT meant for authentication. You should NOT use this package to identify individual users, either directly or indirectly.

If you need server-to-server authentication, you may want to consider OAuth instead. Libraries such as django-oauth-toolkit can help.

Quickstart

Install with pip:

pip install "djangorestframework-api-key==2.*"

Note: It is highly recommended to pin your dependency to the latest major version (as depicted above), as breaking changes may and will happen between major releases.

Add the app to your INSTALLED_APPS:

# settings.py

INSTALLED_APPS = [
  # ...
  "rest_framework",
  "rest_framework_api_key",
]

Run the included migrations:

python manage.py migrate

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog. This project adheres to Semantic Versioning.

2.0.0 - 2020-04-07

NOTE: this release drops compatibility with certain Python and Django versions, but contains no other breaking changes. See Upgrade to 2.0 for detailed migration steps.

Removed

  • Dropped support for Django 2.0 and Django 2.1. (Pull #126)
  • Dropped support for Python 3.5. (Pull #84)

Added

  • Add support for Django 3.0. (Pull #82)
  • Add support for Python 3.8. (Pull #81)
  • Add BaseAPIKeyManager.get_from_key() to allow retrieving API keys from views. (Pull #93)
  • Add type annotations, and partial support for django-stubs and djangorestframework-stubs. (Pull #88, Pull #122)

1.4.1 - 2019-08-24

Added

  • Now ships with type annotations (PEP 561). (Pull #73)

1.4.0 - 2019-07-16

NOTE: this release contains migrations. See Upgrade to v1.4 for detailed instructions.

Added

  • The prefix and hashed_key are now stored in dedicated fields on the APIKey model. (Pull #62)

1.3.0 - 2019-06-28

NOTE: this release contains migrations. In your Django project, run them using:

python manage.py migrate rest_framework_api_key

Added

  • Add abstract API key model (AbstractAPIKey) and base manager (BaseAPIKeyManager). (Pull #36)
  • Add base permissions (BaseHasAPIKey). (Pull #46)

Changed

  • The id field of APIKey is now non-editable.
  • APIKeyModelAdmin does not define fieldsets anymore. This allows subclasses to benefit from Django's automatic fieldsets. (Pull #52)

Fixed

  • Explicitly use utf-8 encoding in setup.py, which could previously lead to issues when installing on certain systems. (Pull #58)

1.2.1 - 2019-06-03

Fixed

  • Fixed a critical bug in APIKeyModelAdmin that prevented rest_framework_api_key from passing Django system checks. (Pull #39)

1.2.0 - 2019-05-29

NOTE: this release contains migrations. In your Django project, run them using:

python manage.py migrate rest_framework_api_key

Added

  • API keys can now have an optional expiry_date. (Pull #33) HasAPIKey denies access if the API key has expired, i.e. if expiry_date, if set, is in the past.
  • It is now possible to search by prefix in the API key admin panel.
  • The prefix is now displayed in the edit view of the API key admin panel.

1.1.0 - 2019-05-14

Added

  • Improve documentation on which password hasher is used.
  • Add tests against the Argon2, BcryptSHA256 and PBKDF2SHA1 hashers. (Pull #32)

Fixed

  • Fix support for password hashers that generate hashes that contain dots. (Pull #31)

1.0.0 - 2019-04-24

This release is incompatible with 0.x. See Upgrade to 1.0 for migration steps.

Removed

  • Remove HasAPIKeyOrIsAuthenticated permission class. You should use bitwise composition now, e.g. HasAPIKey | IsAuthenticated.
  • Drop the DRF_API_KEY_* settings. (Pull #19)

Changed

  • Switch to a new API key generation and validation scheme. Clients must now authorize using a single API key header (Pull #19). The header is Authorization by default. It can be customized using the API_KEY_CUSTOM_HEADER setting (Pull #26). Use the name field to identify clients.

Added

  • Add support for Django 2.2. (Pull #27)
  • Add programmatic API key creation using APIKey.objects.create_key(). (Pull #19)

Fixed

  • Improved API key storage using Django's password hashing helpers. (Uses the default Django password hasher.) (Pull #19)

0.4.0 - 2019-04-21

Removed

  • Drop support for Python 3.4. Only 3.5, 3.6 and 3.7 are supported now.
  • Drop support for Django < 2.0. Only 2.0 and 2.1 are supported now.

Fixed

  • HasAPIKey now implements .has_object_permissions(), which allows to compose it with other permission classes and perform object-level permission checks. (Pull #25)

0.3.1 - 2018-11-17

Initial changelog entry.

Added

  • APIKey model.
  • HasAPIKey and HasAPIKeyOrIsAuthenticated permission classes.
  • Generate, view and revoke API keys from the Django admin.
  • Authenticate requests using the Api-Token and Api-Secret-Key headers. Customizable via the DRF_API_KEY_TOKEN_HEADER and DRF_API_KEY_SECRET_KEY_HEADER settings.
