GetCertificateAuthorityCsr

Il seguente esempio di Java mostra come utilizzare l'GetCertificateAuthorityCsroperazione.

Questa operazione consente di recuperare la richiesta di firma del certificato (CSR) per l'autorità di certificazione (CA) privata. La CSR viene creata quando si chiama l'CreateCertificateAuthorityoperazione. Porta la CSR nell'infrastruttura locale X.509 e firmala utilizzando la CA root o subordinata. Quindi importa nuovamente il certificato firmato in ACM PCA richiamando l'operazione. ImportCertificateAuthorityCertificate Il CSR viene restituito come stringa con codifica Base64 in formato PEM.

L'output deve essere simile al seguente per l'autorità di certificazione (CA) specificata. La richiesta di firma del certificato (CSR) è con codifica base64 nel formato PEM. Salvala in un file locale, portala nell'infrastruttura locale X.509 e firmala utilizzando la CA root o subordinata.
