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

次の Java サンプル例は、[DescribeCertificateAuthorityAuditReport](https://docs.aws.amazon.com/privateca/latest/APIReference/API_DescribeCertificateAuthorityAuditReport.html) オペレーションを使用する方法を示しています。

このオペレーションでは、[CreateCertificateAuthorityAuditReport](https://docs.aws.amazon.com/privateca/latest/APIReference/API_CreateCertificateAuthorityAuditReport.html) オペレーションを呼び出して作成した特定の監査報告書に関する情報がリストされます。監査情報は、認証機関 (CA) プライベートキーが使用されるたびに作成されます。プライベートキーは、証明書を発行、CRL に署名、または証明書を取り消すときに使用されます。
