How to Import SSL Certificates on Windows Server 2022

Securing your website with an SSL certificate is crucial for protecting sensitive data and building user trust. For websites hosted on Windows Server 2022, importing and assigning an SSL certificate from another server is a common task for system administrators. This guide provides a comprehensive, step-by-step walkthrough to help you seamlessly import and install your SSL certificate on Windows Server 2022.

Prerequisites for Importing SSL Certificates

Before you begin, ensure you have the following:

• Administrative Access: You need administrator privileges on your Windows Server 2022.
• SSL Certificate Files: Obtain your SSL certificate files from your Certificate Authority (CA) or the server where it is currently installed. These files typically include:
  • Certificate File (.crt, .cer, .pem): The actual SSL certificate file.
  • Private Key File (.key, .pem): Crucial for SSL to function; keep this secure.
  • Intermediate Certificate Bundles (Optional, .ca-bundle, .crt): May be required for complete chain of trust.
• MMC (Microsoft Management Console): This tool is built into Windows Server and is used to manage certificates.

Step-by-Step: Importing the SSL Certificate into Windows Server 2022

To import the SSL certificate into the local computer’s certificate store, follow these detailed steps:

   • In the Certificates snap-in dialog box, select Computer account. This ensures the certificate is available for services running on the server, like IIS.
   • Click Next.

5. Select Local Computer:
