Version ``1.7.1`` is the last one supporting Python 3.0-3.5. Require cryptography >= 3 ^^^^^^^^^^^^^^^^^^^^^^^^^ Drop support for PyCrypto and ECDSA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ We've kept this around for a long time, mostly for environments that didn't allow installing cryptography. Drop CLI ^^^^^^^^ Dropped the included cli entry point. Improve typings ^^^^^^^^^^^^^^^ We no longer need to use mypy Python 2 compatibility mode (comments) ``jwt.encode(...)`` return type ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Tokens are returned as string instead of a byte string Dropped deprecated errors ^^^^^^^^^^^^^^^^^^^^^^^^^ Removed ``ExpiredSignature``, ``InvalidAudience``, and ``InvalidIssuer``. Use ``ExpiredSignatureError``, ``InvalidAudienceError``, and ``InvalidIssuerError`` instead. Dropped deprecated ``verify_expiration`` param in ``jwt.decode(...)`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Use ``jwt.decode(encoded, key, algorithms=["HS256"], options={"verify_exp": False})`` instead. Dropped deprecated ``verify`` param in ``jwt.decode(...)`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Use ``jwt.decode(encoded, key, options={"verify_signature": False})`` instead. Require explicit ``algorithms`` in ``jwt.decode(...)`` by default ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Example: ``jwt.decode(encoded, key, algorithms=["HS256"])``. Dropped deprecated ``require_*`` options in ``jwt.decode(...)`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For example, instead of ``jwt.decode(encoded, key, algorithms=["HS256"], options={"require_exp": True})``, use ``jwt.decode(encoded, key, algorithms=["HS256"], options={"require": ["exp"]})``. Added ~~~~~ Introduce better experience for JWKs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Introduce ``PyJWK``, ``PyJWKSet``, and ``PyJWKClient``. .. code:: python import jwt from jwt import PyJWKClient token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6Ik5FRTFRVVJCT1RNNE16STVSa0ZETlRZeE9UVTFNRGcyT0Rnd1EwVXpNVGsxUWpZeVJrUkZRdyJ9.eyJpc3MiOiJodHRwczovL2Rldi04N2V2eDlydS5hdXRoMC5jb20vIiwic3ViIjoiYVc0Q2NhNzl4UmVMV1V6MGFFMkg2a0QwTzNjWEJWdENAY2xpZW50cyIsImF1ZCI6Imh0dHBzOi8vZXhwZW5zZXMtYXBpIiwiaWF0IjoxNTcyMDA2OTU0LCJleHAiOjE1NzIwMDY5NjQsImF6cCI6ImFXNENjYTc5eFJlTFdVejBhRTJINmtEME8zY1hCVnRDIiwiZ3R5IjoiY2xpZW50LWNyZWRlbnRpYWxzIn0.PUxE7xn52aTCohGiWoSdMBZGiYAHwE5FYie0Y1qUT68IHSTXwXVd6hn02HTah6epvHHVKA2FqcFZ4GGv5VTHEvYpeggiiZMgbxFrmTEY0csL6VNkX1eaJGcuehwQCRBKRLL3zKmA5IKGy5GeUnIbpPHLHDxr-GXvgFzsdsyWlVQvPX2xjeaQ217r2PtxDeqjlf66UYl6oY6AqNS8DH3iryCvIfCcybRZkc_hdy-6ZMoKT6Piijvk_aXdm7-QQqKJFHLuEqrVSOuBqqiNfVrG27QzAPuPOxvfXTVLXL2jek5meH6n-VWgrBdoMFH93QEszEDowDAEhQPHVs0xj7SIzA" kid = "NEE1QURBOTM4MzI5RkFDNTYxOTU1MDg2ODgwQ0UzMTk1QjYyRkRFQw" url = "https://dev-87evx9ru.auth0.com/.well-known/jwks.json" jwks_client = PyJWKClient(url) signing_key = jwks_client.get_signing_key_from_jwt(token) data = jwt.decode( token, signing_key.key, algorithms=["RS256"], audience="https://expenses-api", options={"verify_exp": False}, ) print(data) Support for JWKs containing ECDSA keys ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Add support for Ed25519 / EdDSA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Pull Requests ~~~~~~~~~~~~~ - Add PyPy3 to the test matrix (#550) by @jdufresne - Require tweak (#280) by @psafont - Decode return type is dict[str, Any] (#393) by @jacopofar - Fix linter error in test\_cli (#414) by @jaraco - Run mypy with tox (#421) by @jpadilla - Document (and prefer) pyjwt[crypto] req format (#426) by @gthb - Correct type for json\_encoder argument (#438) by @jdufresne - Prefer https:// links where available (#439) by @jdufresne - Pass python\_requires argument to setuptools (#440) by @jdufresne - Rename [wheel] section to [bdist\_wheel] as the former is legacy (#441) by @jdufresne - Remove setup.py test command in favor of pytest and tox (#442) by @jdufresne - Fix mypy errors (#449) by @jpadilla - DX Tweaks (#450) by @jpadilla - Add support of python 3.8 (#452) by @Djailla - Fix 406 (#454) by @justinbaur - Add support for Ed25519 / EdDSA, with unit tests (#455) by @Someguy123 - Remove Python 2.7 compatibility (#457) by @Djailla - Fix simple typo: encododed -> encoded (#462) by @timgates42 - Enhance tracebacks.
