GetCertificate - Amazon Certificate Manager
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).


Retrieves a certificate and its certificate chain. The certificate may be either a public or private certificate issued using the ACM RequestCertificate action, or a certificate imported into ACM using the ImportCertificate action. The chain consists of the certificate of the issuing CA and the intermediate certificates of any other subordinate CAs. All of the certificates are base64 encoded. You can use OpenSSL to decode the certificates and inspect individual fields.
