<p>Creates an X.509 certificate using the specified certificate signing request. </p> <p>Requires permission to access the <a href="https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions">CreateCertificateFromCsr</a> action. </p> <note> <p>The CSR must include a public key that is either an RSA key with a length of at least 2048 bits or an ECC key from NIST P-25 or NIST P-384 curves. For supported certificates, consult <a href="https://docs.aws.amazon.com/iot/latest/developerguide/x509-client-certs.html#x509-cert-algorithms"> Certificate signing algorithms supported by IoT</a>. </p> </note> <note> <p>Reusing the same certificate signing request (CSR) results in a distinct certificate.</p> </note> <p>You can create multiple certificates in a batch by creating a directory, copying multiple <code>.csr</code> files into that directory, and then specifying that directory on the command line. The following commands show how to create a batch of certificates given a batch of CSRs. In the following commands, we assume that a set of CSRs are located inside of the directory my-csr-directory:</p> <p>On Linux and OS X, the command is: </p> <p> <code>$ ls my-csr-directory/ | xargs -I {} aws iot create-certificate-from-csr --certificate-signing-request file://my-csr-directory/{}</code> </p> <p>This command lists all of the CSRs in my-csr-directory and pipes each CSR file name to the <code>aws iot create-certificate-from-csr</code> Amazon Web Services CLI command to create a certificate for the corresponding CSR. </p> <p>You can also run the <code>aws iot create-certificate-from-csr</code> part of the command in parallel to speed up the certificate creation process:</p> <p> <code>$ ls my-csr-directory/ | xargs -P 10 -I {} aws iot create-certificate-from-csr --certificate-signing-request file://my-csr-directory/{} </code> </p> <p>On Windows PowerShell, the command to create certificates for all CSRs in my-csr-directory is:</p> <p> <code>&gt; ls -Name my-csr-directory | %{aws iot create-certificate-from-csr --certificate-signing-request file://my-csr-directory/$_} </code> </p> <p>On a Windows command prompt, the command to create certificates for all CSRs in my-csr-directory is:</p> <p> <code>&gt; forfiles /p my-csr-directory /c "cmd /c aws iot create-certificate-from-csr --certificate-signing-request file://@path" </code> </p>
