How to export a digital certificate in Windows 11

To export a digital certificate in Windows 11, you'll typically use the Certificate Management Console (certmgr.msc) to locate the certificate, then use the Export Wizard to back it up. The process involves specifying the file format (PFX), including the private key, and optionally setting a password for security. 

Here's a step-by-step guide with image examples:

  1. 1. Open Certificate Management Console:

    • Click the Start menu, type "certmgr.msc", and press Enter.

    • In the console tree, navigate to Certificates - Current User (or Computer) > Personal > Certificates. 

  2. 2. Select and Export:

    • Right-click the certificate you want to export, and select "All Tasks" > "Export". 

    • The Certificate Export Wizard will open. 

  3. 3. Export Wizard Steps:

    • Welcome screen: Click Next to proceed. 

    • Export Private Key: Choose "Yes, export the private key" and click Next. 

    • File Format: Select "Personal Information Exchange - PKCS#12 (.PFX)" and click Next. 

    • Include Certificates: If desired, check "Include all certificates in the certification path if possible" and "Export all extended properties". 

    • Password (Optional): If you want to protect the certificate with a password, check "Password" and enter a password, then click Next. 

    • File Location: Click Browse to choose a location on your computer to save the exported file (e.g., a .pfx file). 

    • Summary: Review the settings and click Finish. 

  4. 4. Confirmation:

    • You'll receive a confirmation message indicating that the export was successful. 

    • Click OK to close the wizard. 

This exported .pfx file can then be used to back up your certificate and potentially import it into another system or browser if needed.
