GetCertificateAuthorityCsr

다음 Java 샘플은 GetCertificateAuthorityCsr작업 사용 방법을 보여줍니다.

이 작업은 사설 인증 기관(CA)을 위한 인증서 서명 요청(CSR)을 검색합니다. CSR은 CreateCertificateAuthority오퍼레이션을 호출할 때 생성됩니다. CSR을 온프레미스 X.509 인프라로 가져와서 루트 또는 하위 CA를 사용해 서명합니다. 그런 다음 작업을 호출하여 서명된 인증서를 ACM PCA로 다시 가져옵니다. ImportCertificateAuthorityCertificate CSR은 PEM 형식의 base64 인코딩 문자열로 반환됩니다.

지정한 CA(인증 기관)에 대한 출력은 다음과 유사해야 합니다. 인증서 서명 요청(CSR)은 PEM 형식으로 base64로 인코딩됩니다. CSR을 로컬 파일에 저장하고 온프레미스 X.509 인프라로 가져와서 루트 또는 하위 CA를 사용해 서명합니다.
