# 🛡️ USSO Python Client SDK
The **USSO Python Client SDK** (`usso`) provides a universal, secure JWT authentication layer for Python microservices and web frameworks.
It’s designed to integrate seamlessly with the [USSO Identity Platform](https://github.com/ussoio/usso) — or any standards-compliant token issuer.
---
## 🔗 Relationship to the USSO Platform
This SDK is the official verification client for the **USSO** identity service, which provides multi-tenant authentication, RBAC, token flows, and more.
You can use the SDK with:
- Self-hosted USSO via Docker
- Any identity provider that issues signed JWTs (with proper config)
---
## ✨ Features
- ✅ **Token verification** for EdDSA, RS256, HS256, and more
- ✅ **Claim validation** (`exp`, `nbf`, `aud`, `iss`)
- ✅ **Remote JWK support** for key rotation
- ✅ **Typed payload parsing** via `UserData` (Pydantic)
- ✅ **Token extraction** from:
- `Authorization` header
- Cookies
- Custom headers
- ✅ **FastAPI integration** with dependency injection
- ✅ **Django middleware** for request-based user resolution
- 🧪 90% tested with `pytest` and `tox`
---
## 📦 Installation
```bash
pip install usso
````
With framework extras:
```bash
pip install "usso[fastapi]" # for FastAPI integration
pip install "usso[django]" # for Django integration
```
---
## 🚀 Quick Start (FastAPI)
```python
from usso.fastapi.integration import get_authenticator
from usso.schemas import JWTConfig, JWTHeaderConfig, UserData
from usso.jwt.enums import Algorithm
config = JWTConfig(
key="your-ed25519-public-key",
issuer="https://sso.example.com",
audience="api.example.com",
type=Algorithm.EdDSA,
header=JWTHeaderConfig(type="Authorization")
)
authenticator = get_authenticator(config)
@app.get("/me")
def get_me(user: UserData = Depends(authenticator)):
return {"user_id": user.sub, "roles": user.roles}
```
---
## 🧱 Project Structure
```
src/usso/
├── fastapi/ # FastAPI adapter
├── django/ # Django middleware
├── jwt/ # Core JWT logic and algorithms
├── session/ # Stateless session support
├── models/ # JWTConfig, UserData, etc.
├── exceptions/ # Shared exceptions
├── authenticator.py # High-level API (token + user resolution)
```
---
## 🐳 Integrate with USSO (Docker)
Run your own identity provider:
```bash
docker run -p 8000:8000 ghcr.io/ussoio/usso:latest
```
Then configure your app to verify tokens issued by this service, using its public JWKS endpoint:
```python
JWTConfig(
jwks_url="http://localhost:8000/.well-known/jwks.json",
...
)
```
---
## 🧪 Testing
```bash
pytest
tox
```
