The JavaScript Object Signing and Encryption (JOSE) technologies - JSON
Web Signature (JWS), JSON Web Encryption (JWE), JSON Web Key (JWK), and
JSON Web Algorithms (JWA) - collectively can be used to encrypt and/or
sign content using a variety of algorithms. While the full set of
permutations is extremely large, and might be daunting to some, it is
expected that most applications will only use a small set of algorithms
to meet their needs.


Installation
------------

::

    $ pip install python-jose[cryptography]


Cryptographic Backends
----------------------

As of 3.3.0, python-jose implements three different cryptographic backends.
The backend must be selected as an extra when installing python-jose.
If you do not select a backend, the native-python backend will be installed.

Unless otherwise noted, all backends support all operations.

Due to complexities with setuptools, the native-python backend is always installed,
even if you select a different backend on install.
We recommend that you remove unnecessary...

## AI interpretation — verify before relying

Implements JOSE (JSON Object Signing and Encryption) standards including JWS, JWE, JWK, and JWA to sign and encrypt JSON-based content using various cryptographic algorithms.

Verdict: Production-ready JOSE library with active maintenance, no known vulnerabilities, and permissive licensing. Low install friction and broad algorithm support make it suitable for JWT and encryption workflows. Choose your cryptographic backend at install time based on performance and feature needs.
