# 인증서 갱신
<a name="sdk-renew"></a>

다음 예제에서는 [RenewCertificate](https://docs.aws.amazon.com/acm/latest/APIReference/API_RenewCertificate.html) 함수를 사용하는 방법을 보여 줍니다. 이 함수는 Private Certificate Authority(CA)에서 발급하고 [ExportCertificate](https://docs.aws.amazon.com/acm/latest/APIReference/API_ExportCertificate.html) 함수로 내보낸 사설 인증서를 갱신합니다. 이때 내보낸 사설 인증서만을 이 함수로 갱신할 수 있습니다. ACM으로 AWS Private CA 인증서를 갱신하려면 먼저 ACM 서비스 보안 주체에게 권한을 부여해야 합니다. 자세한 내용은 [ACM에 인증서 갱신 권한 할당](https://docs.aws.amazon.com/privateca/latest/userguide/assign-permissions.html#PcaPermissions)을 참조하세요.
