请确保创建并激活一个[虚拟环境](../../virtual-environments.md)，然后安装 `pyjwt`：

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | 信息

如果你计划使用类似 RSA 或 ECDSA 的数字签名算法，你应该安装加密库依赖项 `pyjwt[crypto]`。

可以在 [PyJWT 安装文档](https://pyjwt.readthedocs.io/en/latest/installation.html)中了解更多。

## 密码哈希 { #password-hashing }

“哈希”是指把一些内容（这里是密码）转换成看起来像乱码的一串字节（其实就是字符串）。

当你每次传入完全相同的内容（完全相同的密码）时，都会得到完全相同的“乱码”。

/// info | 정보

RSA나 ECDSA 같은 전자 서명 알고리즘을 사용할 계획이라면, cryptography 라이브러리 의존성인 `pyjwt[crypto]`를 설치해야 합니다.

자세한 내용은 [PyJWT 설치 문서](https://pyjwt.readthedocs.io/en/latest/installation.html)에서 확인할 수 있습니다.
