    4. After you place the order to renew your certificate, DigiCert verifies your information.

      If we need any additional information, we will promptly contact you by phone or email. If no additional information is required, we will most likely issue your certificate within an hour.

2. How to Import Your SSL Certificate Using the DigiCert Utility

After your renewal SSL Certificate has been issued, you need to run the DigiCert Certificate Utility to import it to your IIS 7 server.

  1. After receiving your new certificate file from DigiCert, save the file to the IIS 7 server where you created the CSR.

  2. On the same server, run the DigiCert® Certificate Utility for Windows.

    Double-click DigiCertUtil.

  3. In DigiCert Certificate Utility for Windows©, click SSL (gold lock) and then, click Import.

    Import an IIS 8 .cer certificate

  4. In the Certificate Import wizard, click Browse to browse to the .cer certificate file (i.e. your_domain_com.cer) that DigiCert sent you, select the file, click Open, and then, click Next.

    Import your_domain_com.cer

  5. In the Enter a new friendly name or you can accept the default box, type a friendly name for the certificate.

    Note:    The friendly name is not part of the certificate; instead, it is used to identify the certificate.

    We recommend that you add DigiCert and the expiration date to the end of your friendly name, for example: yoursite-digicert-(expiration date). This information helps identify the issuer and expiration date for each certificate. It also helps distinguish multiple certificates with the same domain name.

    Assign a Friendly Name

  6. To import the SSL Certificate to your server, click Finish.

    You should receive "Your certificate has been successfully imported" message. You are now ready to assign/configure your server software to use the renewed SSL Certificate.
