## `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

---> 100%
```

</div>

/// info | 참고

RSA나 ECDSA 같은 전자 서명 알고리즘을 사용하려면, `pyjwt[crypto]`라는 암호화 라이브러리 의존성을 설치해야 합니다.
