## What it is
PyJWT is a Python library implementing JSON Web Tokens (JWT) per RFC 7519, supporting encoding and decoding of signed tokens. It is the de facto standard JWT library for Python, published on PyPI as PyJWT.

## Use cases
- encode and decode JWTs in Python
- sign tokens with HS256 or other algorithms
- verify JWT signatures in a web API
- issue access tokens for authentication
- validate expired or malformed tokens

## When to choose
- you need standards-compliant JWT handling in a Python project
- you want a lightweight, well-maintained library with no heavy dependencies
- you need flexible algorithm support including asymmetric signing

## When to avoid
- you need a full identity/auth provider rather than a token library
- you need JWE encryption, which PyJWT does not fully cover
- your framework already bundles its own JWT handling

## Facets
- artifact type: library
- maturity: stable
- function: auth, cryptography, serialization
- domain: security, web-development, developer-tools
- platform: python, cross-platform
- tags: jwt, json-web-tokens, token-signing, rfc7519, authentication
