IssueCertificate

The following Java sample shows how to use the IssueCertificate function.

This function uses your private certificate authority (CA) to issue a private certificate. This action returns the Amazon Resource Name (ARN) of the certificate. You can retrieve the certificate by calling the GetCertificate and specifying the ARN.

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 java.nio.ByteBuffer; import java.nio.charset.StandardCharsets; import java.util.Objects; import com.amazonaws.services.acmpca.AWSACMPCA; import com.amazonaws.services.acmpca.AWSACMPCAClientBuilder; import com.amazonaws.services.acmpca.model.IssueCertificateRequest; import com.amazonaws.services.acmpca.model.IssueCertificateResult; import com.amazonaws.services.acmpca.model.SigningAlgorithm; import com.amazonaws.services.acmpca.model.Validity; import com.amazonaws.AmazonClientException; import com.amazonaws.services.acmpca.model.LimitExceededException; import com.amazonaws.services.acmpca.model.ResourceNotFoundException; import com.amazonaws.services.acmpca.model.InvalidStateException; import com.amazonaws.services.acmpca.model.InvalidArnException; import com.amazonaws.services.acmpca.model.InvalidArgsException; import com.amazonaws.services.acmpca.model.MalformedCSRException; public class IssueCertificate { public static ByteBuffer stringToByteBuffer(final String string) { if (Objects.isNull(string)) { return null; } byte[] bytes = string.getBytes(StandardCharsets.UTF_8); return ByteBuffer.wrap(bytes); } 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 endpointProtocol = "https://acm-pca.region.amazonaws.com/"; String endpointRegion = "region"; 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 certificate request: IssueCertificateRequest req = new IssueCertificateRequest(); // Set the CA ARN. req.withCertificateAuthorityArn("arn:aws:acm-pca:region:account:" + "certificate-authority/12345678-1234-1234-1234-123456789012"); // Specify the certificate signing request (CSR) for the certificate to be signed and issued. String strCSR = "-----BEGIN CERTIFICATE REQUEST-----" + " base64-encoded certificate " + "------END CERTIFICATE REQUEST------"; ByteBuffer csrByteBuffer = stringToByteBuffer(strCSR); req.setCsr(csrByteBuffer); // Set the signing algorithm. req.withSigningAlgorithm(SigningAlgorithm.SHA256WITHRSA); // Set the validity period for the certificate to be issued. Validity validity = new Validity(); validity.withValue(3650L); validity.withType("DAYS"); req.withValidity(validity); // Set the idempotency token. req.setIdempotencyToken("1234"); // Issue the certificate. IssueCertificateResult result = null; try{ result = client.issueCertificate(req); } catch(LimitExceededException ex) { throw ex; } catch(ResourceNotFoundException ex) { throw ex; } catch(InvalidStateException ex) { throw ex; } catch (InvalidArnException ex) { throw ex; } catch (InvalidArgsException ex) { throw ex; } catch (MalformedCSRException ex) { throw ex; } // Retrieve and display the certificate ARN. String arn = result.getCertificateArn(); System.out.println(arn); } }

Your output should be similar to the following.

arn:aws:acm-pca:region:account:certificate-authority/12345678-1234-1234-1234-123456789012/certificate/2669d5cacb539c0830998c23babab8dc
