GetCertificateAuthorityCertificate - AWS Certificate Manager Private Certificate Authority

GetCertificateAuthorityCertificate

The following Java sample shows how to use the GetCertificateAuthorityCertificate operation.

This operation retrieves the certificate and certificate chain for your private certificate authority (CA). Both the certificate and the chain are base64-encoded strings in PEM format. The chain does not include the CA certificate. Each certificate in the chain signs the one before it.

package com.amazonaws.samples; import com.amazonaws.auth.AWSCredentials; import com.amazonaws.auth.profile.ProfileCredentialsProvider; import com.amazonaws.client.builder.AwsClientBuilder; import com.amazonaws.client.builder.AwsClientBuilder.EndpointConfiguration; import com.amazonaws.auth.AWSStaticCredentialsProvider; import com.amazonaws.services.acmpca.AWSACMPCA; import com.amazonaws.services.acmpca.AWSACMPCAClientBuilder; import com.amazonaws.services.acmpca.model.GetCertificateAuthorityCertificateRequest; import com.amazonaws.services.acmpca.model.GetCertificateAuthorityCertificateResult; import com.amazonaws.AmazonClientException; import com.amazonaws.services.acmpca.model.ResourceNotFoundException; import com.amazonaws.services.acmpca.model.InvalidStateException; import com.amazonaws.services.acmpca.model.InvalidArnException; public class GetCertificateAuthorityCertificate { public static void main(String[] args) throws Exception { // Retrieve your credentials from the C:\Users\name\.aws\credentials file // in Windows or the .aws/credentials file in Linux. AWSCredentials credentials = null; try { credentials = new ProfileCredentialsProvider("default").getCredentials(); } catch (Exception e) { throw new AmazonClientException("Cannot load your credentials from disk", e); } // Define the endpoint for your sample. String endpointRegion = "region"; // Substitute your region here, e.g. "us-west-2" String endpointProtocol = "https://acm-pca." + endpointRegion + ".amazonaws.com/"; EndpointConfiguration endpoint = new AwsClientBuilder.EndpointConfiguration(endpointProtocol, endpointRegion); // Create a client that you can use to make requests. AWSACMPCA client = AWSACMPCAClientBuilder.standard() .withEndpointConfiguration(endpoint) .withCredentials(new AWSStaticCredentialsProvider(credentials)) .build(); // Create a request object GetCertificateAuthorityCertificateRequest req = new GetCertificateAuthorityCertificateRequest(); // Set the certificate authority ARN, req.withCertificateAuthorityArn("arn:aws:acm-pca:region:account:" + "certificate-authority/12345678-1234-1234-1234-123456789012"); // Create a result object. GetCertificateAuthorityCertificateResult result = null; try { result = client.getCertificateAuthorityCertificate(req); } catch (ResourceNotFoundException ex) { throw ex; } catch (InvalidStateException ex) { throw ex; } catch (InvalidArnException ex) { throw ex; } // Retrieve and display the certificate information. String strPcaCert = result.getCertificate(); System.out.println(strPcaCert); String strPCACChain = result.getCertificateChain(); System.out.println(strPCACChain); } }

Your output should be a certificate and chain similar to the following for the certificate authority (CA) that you specified.

-----BEGIN CERTIFICATE----- base64-encoded certificate -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- base64-encoded certificate -----END CERTIFICATE-----
