## 安装 `python-jose`

安装 `python-jose`，在 Python 中生成和校验 JWT 令牌：

<div class="termy">

```console
$ pip install python-jose[cryptography]

---> 100%
```

</div>

<a href="https://github.com/mpdavis/python-jose" class="external-link" target="_blank">Python-jose</a> 需要安装配套的加密后端。

    # TODO: remove after upgrading python-jose to a version that explicitly supports Python 3.12
    # also, if it won't receive an update, consider replacing python-jose with some alternative
    # related issues:
    #   - https://github.com/mpdavis/python-jose/issues/332
    #   - https://github.com/mpdavis/python-jose/issues/334

## `python-jose` installieren.

Wir müssen <abbr title="JOSE: JavaScript Object Signing and Encryption">`python-jose`</abbr> installieren, um die JWT-Tokens in Python zu generieren und zu verifizieren:

<div class="termy">

```console
$ pip install "python-jose[cryptography]"

---> 100%
```

## Install `python-jose`

We need to install `python-jose` to generate and verify the JWT tokens in Python:

<div class="termy">

```console
$ pip install "python-jose[cryptography]"

---> 100%
```

</div>

<a href="https://github.com/mpdavis/python-jose" class="external-link" target="_blank">Python-jose</a> requires a cryptographic backend as an extra.

## `python-jose` のインストール

PythonでJWTトークンの生成と検証を行うために、`python-jose`をインストールする必要があります：

<div class="termy">

```console
$ pip install python-jose[cryptography]

---> 100%
```

</div>

また、<a href="https://github.com/mpdavis/python-jose" class="external-link" target="_blank">Python-jose</a>だけではなく、暗号を扱うためのパッケージを追加で必要とします。
