SSL/TLSサーバ証明書を複製する

すべてのデジサート証明書には、無制限の無料複製発行が含まれています。複数のサーバーでセキュリティを強化し、証明書をインストールしやすくするには、新しいCSRを生成して、サーバーそれぞれに複製証明書を作成します。

複製証明書の詳細は、元の証明書と全く同じです。複製証明書では、デジサートが証明書の以前のコピーを失効させる必要は一切ありません。

Before you begin

Duplicate certificates require you to complete the domain and organization validation before requesting the certificate. Unlike the reissue process, the duplicate certificate process does not include a workflow for validating domains and organizations.

Unfortunately, DV TLS/SSL certificates do not allow duplicates. This is because domain validation for a DV certificate request only applies to issuing that specific certificate. So, each time you request a DV TLS/SSL certificate, you must demonstrate control over the domains on that request.

To get a duplicate DV TLS/SSL certificate, reissue your certificate instead.

複製証明書を作成する

複製証明書を取得するには、以下ののステップを実行してください。

  1. Generate CSR

    To duplicate an SSL/TLS certificate, you must generate a new CSR. For more information about creating a CSR, see the Create a CSR (Certificate Signing Request) knowledge base article.

  2. Sign in to your account

    CertCentral sign-in page.

  3. Fill out the Request Duplicate form

    1. In the left menu, go to Certificates > Orders.

    2. On the Orders page, select the Order # of the certificate you want a duplicate of.

    3. On the certificate's Order # details page, in the Certificate actionsdropdown, select Request duplicate.

    4. Fill out the Request Duplicate certificate form, update the certificate details as needed, and submit the request.

      1. Add your CSR

        Upload or paste your CSR in the form.

      2. Certificate validity

        By default, a duplicate expiration date matches the certificate you are duplicating.

        Next, to Certificate details, select the pencil (edit icon) to modify the validity date if needed.

      3. Signature hash

        In the dropdown, select a different signature hash if needed.

      4. Server platform

        In the dropdown, select the server platform on which you will install the certificate.

  4. DigiCert issues the duplicate SSL/TLS certificate

    Once approved, we issue and email the duplicate certificate to the certificate contact. You can also download the duplicate certificate from your account and specify the format. See Download a certificate from your account.

  5. Install your duplicate SSL/TLS certificate

    Install and configure the new certificate. For more information about installing your certificate, see our SSL Certificate Installation Instructions and Tutorials page.
