Flask-PASETO-Extended is a Flask extension to use [PASETO (Platform-Agnostic Security Tokens)](https://paseto.io/) for several purposes.

For encoding/decoding PASETO, we have adopted [PySETO](https://github.com/dajiaji/pyseto),
which is a PASETO implementation supporting all of PASETO versions (
[v4](https://github.com/paseto-standard/paseto-spec/blob/master/docs/01-Protocol-Versions/Version4.md),
[v3](https://github.com/paseto-standard/paseto-spec/blob/master/docs/01-Protocol-Versions/Version3.md),
[v2](https://github.com/paseto-standard/paseto-spec/blob/master/docs/01-Protocol-Versions/Version2.md) and
[v1](https://github.com/paseto-standard/paseto-spec/blob/master/docs/01-Protocol-Versions/Version1.md)) and purposes (`local` and `public`).

Currently, we provide the following classes for using PASETO with Flask:

- **PasetoCookieSessionInterface**
  - Flask (`Flask.sessions`) stores session information as a Cookie value. By using this class, you can serialize the session information as an encrypted (and then MACed) PASETO.
- **PasetoLoginManager**
  - By using this class together with [Flask-Login](https://github.com/maxcountryman/flask-login), you can use PASETO for remember-me tokens which is also encoded into a Cookie value.
- **PasetoManager**
  - This class can be used for verifying public (signed) PASETO. It is suitable for using PASETO as API tokens (NOTE: under construction).

## Installation

You can install Flask-PASETO-Extended with pip:

```py
$ pip install flask-paseto-extended
```

## Usage

Flask-PASETO-Extended provides three classes for each purpose.

### PasetoCookieSessionInterface

Flask (`Flask.sessions`) stores session information as a Cookie value. By using this class, you can serialize the session information as an encrypted (and then MACed) PASETO.

This class can be used as follows:

```py
import flask
from flask_paseto_extended import PasetoCookieSessionInterface

app = flask.Flask(__name__)
app.secret_key = "super secret string"

# Use PASETO("v4" by default) for cookie sessions.
app.session_interface = PasetoCookieSessionInterface()
```

See [examples/cookie_session.py](https://github.com/dajiaji/flask-paseto-extended/blob/main/examples/cookie_session.py) for a sample code that actually works.

### PasetoLoginManager

By using this class together with [Flask-Login](https://github.com/maxcountryman/flask-login), you can use PASETO for remember-me tokens which is also encoded into a Cookie value.

This class can be used as follows:

```py
import flask
import flask_login
# Import PasetoLoginManager instead of flask_login.LoginManager.
from flask_paseto_extended import PasetoLoginManager

app = flask.Flask(__name__)
app.secret_key = "super secret string"

login_manager = PasetoLoginManager(app)
```

See [examples/login_manager.py](https://github.com/dajiaji/flask-paseto-extended/blob/main/examples/login_manager.py) for a sample code that actually works.

### PasetoManager

This class can be used for verifying public (signed) PASETO. It is suitable for using PASETO as API tokens (NOTE: under construction).
