## FastAPI Authentication Implementation Guide
### Overview
This document describes the implementation of JWT-based authentication in a FastAPI application.
### Requirements
- Python 3.8+
- FastAPI
- PyJWT
- passlib
### Implementation Steps
1. Install Dependencies
```bash
pip install fastapi pyjwt passlib[bcrypt]
```
2. Set Up JWT Configuration
```python
from datetime import datetime, timedelta
from jose import JWTError, jwt
SECRET_KEY = "your-secret-key"
ALGORITHM = "HS256"
ACCESS_TOKEN_EXPIRE_MINUTES = 30
```
3. Create Token Generation Function
```python
def create_access_token(data: dict):
to_encode = data.copy()
expire = datetime.utcnow() + timedelta(minutes=ACCESS_TOKEN_EXPIRE_MINUTES)
to_encode.update({"exp": expire})
encoded_jwt = jwt.encode(to_encode, SECRET_KEY, algorithm=ALGORITHM)
return encoded_jwt
```
This technical documentation should be converted into a more comprehensive guide with examples and best practices.
