만약 JWT 토큰을 다뤄보고, 작동 방식도 알아보고 싶다면 <a href="https://jwt.io/" class="external-link" target="_blank">https://jwt.io</a> 을 확인하십시오.

## `PyJWT` 설치

파이썬으로 JWT 토큰을 생성하고 검증하려면 `PyJWT` 를 설치해야 합니다.

[가상환경](../../virtual-environments.md){.internal-link target=_blank} 을 만들고 활성화한 다음 `pyjwt` 를 설치하십시오:

<div class="termy">

```console
$ pip install pyjwt
