# RevokeCertificate
<a name="JavaApi-RevokeCertificate"></a>

下列 Java 範例示範如何使用 [RevokeCertificate](https://docs.aws.amazon.com/privateca/latest/APIReference/API_RevokeCertificate.html) 操作。

此操作可撤銷您透過呼叫 [IssueCertificate](https://docs.aws.amazon.com/privateca/latest/APIReference/API_IssueCertificate.html) 操作發行的憑證。如果您在建立或更新私有 CA 時啟用憑證撤銷清單 (CRL)，CRL 中會包含已撤銷憑證的相關資訊。 會將 CRL AWS 私有 CA 寫入您指定的 Amazon S3 儲存貯體。如需詳細資訊，請參閱 [CrlConfiguration](https://docs.aws.amazon.com/privateca/latest/APIReference/API_CrlConfiguration.html) 結構。
